I still think the problem with our understanding of time is that we are trying to model the present moving along the series of events as some form of vector, rather than considering the present as what is physically real and it is the changing configuration which collapses future probability into actual events and then replaces them. We are not traveling the fourth dimension from yesterday to tomorrow. Tomorrow becomes yesterday because the earth rotates. The reason clocks run at different rates is because different energy levels change the clock rates. The twin out in space simply has a higher metabolic rate, due to the gravity field slowing the metabolic rate of the one remaining on earth. They are not traveling along different vectors of time and one is not further into the future.
Essentially time, rate of change, is similar to temperature, level of activity. Both are quite real, but as emergent effects, not fundamental geometry.
Remember that when these ideas were first being developed, over a hundred years ago, prior even to World War One, knowledge and thinking were respectably linear. Cause preceded effect on the narrative timeline and Newton and his idea of the absolute flow of time were still a direct part of the intellectual landscape. Of course, up until Galileo and Copernicus, it seemed quite natural to think of the sun as moving, not the earth. Our entire sense of historical evolution is based on this idea of the present as moving from the past into the future, so it makes sense to include it into our physical models, but just like geocentric cosmology, the physics is the reciprocal of our perception. It is the events which coalesce out of potential action and are replaced.
Time is not a vector, it is a process. All the complex geometric modeling in the universe is not going to make past or future events physically real. There is only what is manifest.

John,
The definitions are so we can communicate using the same terms for the same things. And different terms for different things rather than muddling them up and confusing ourselves and each other. Like you saying about the existing arrangement of the universe "it is the current manifestation" when I am using the term manifestation only to mean what the observer sees and not the "stuff" of the universe at all. We can not precisely share and exchange and compare ideas if we are not using the language consistently.
I thought addressing language used to communicate ideas was a sensible suggestion arising from the conference. I have mentioned before the ambiguity of the word "time" and the various different meanings it can have. I have since seen others doing the same. The ideas can only be explained without ambiguity when the confusion arising from the language, used to express the ideas, is eliminated. I have repeated the same things over and over so many times in part to try and overcome the ambiguity and misunderstandings real or potential arising from the language I have used to explain them.
If people are going to talk about the subtle differences of snow the language to do so is necessary. If they want to talk about the subtleties of time the language to do so is necessary. Likewise if two people are to talk meaningfully about consciousness. Time is my focus of attention so I have set out what I mean when I use those terms pertaining to time.
Re your temperature analogy:
If I think of lots of particles moving around and if the temperature increases they move around faster, then there is more change at the higher temperature. However it is still has to be change within a unitemporal space where everything exists simultaneously. So time can not pass faster in some places than others. Though rate of change or rate of reaction can be faster in different places.
This means that some parts of the space can have -more- change than others but also there is still the steady change of everything. The unobserved trajectory of everything at all scales. The rotations, translations and scaling transformations of particles , macroscopic objects, planets, star systems, galaxies. It is that entire -all scales- change, of everything changing spatial position together that is passage of time IMHO. Not the dance of individual particles considered at a single scale and considered in isolation from the entirety of the object universe.

John,
I don't know if this sounds bizarre to you. I'm thinking about it like this. Analogy; If there is a putty ball and it is squashed into a different shape some parts can be squashed more than others but it is still just one putty ball existing at one time. The whole thing has to change together. Thats what its like for the Object universe. It isn't moving through time, or being spread across time or moving along a time dimension, or have different parts existing at different times because time is running faster in some parts than others. It just is all together in space.
I don't think it matters if you consider it from the smallest scale up or the largest scale down, however much spatial change is happening doesn't alter the time at which the Object universe exists.It is always there/then ahead of all present manifestations and measured time. Also it isn't directly observed so there is nothing to compare against steady change of a clock.
It is timeless but that sequential change of spatial arrangement is giving observed changes which we measure against clocks and call passage of time, even though the changes in space-time observed manifestation are not identical to what is occurring unobserved in unitemporal/timeless space, due to data transmission delays and data processing time and the effect of observer reference frame.

However the Image Universe -does- appear to be spread over time as well as space, because data persists over time within the environment. So rather than there only being the singular existent arrangement of the universe, there are lots of potential -former- arrangements that might be observed.
That which is observed from our perspective within the object Universe is not -the Universe out there- but manifestations produced from -interpretation- of data persisting within uni-temporal space. "Artistic" spatial and temporal fabrications. Not necessarily even representing EM emitted from still existent bodies anywhere out in space. Produced from ancient emissions and reflections, shadows and products of affects upon the transmission of EM... and the imagination of the artist astronomer.

I feel that your terminology and emphasis on time might be confusing matters. Why don't you just say: 1 Within the inescapable limitations of our existence there is a reality which exists independently of us. 2 Our awareness of that occurs with the receipt of sensory representations of it (you tend to concentrate on sight, when there are others). 3 This process of experiencing reality not only involves only medium based representations, but it is effected at the individual level, is subject to interpretation based on culture, etc, etc. 4 Therefore, in order to extrapolate the underlying reality, one needs to strip out all these interferences and reverse engineer the core sensory representation.

We are very much in agreement on the physics. I'm just making points in terms of both conceptual and tactical perspectives. As there is no God's eye view on all this, we are all coming into the discussion with very subjective perspectives and that is the nature of the beast. For your own good, you can't engage in this discussion under the assumption there is an objective judging process.
In my various conversations with Tom, he would frequently make the pint that spacetime is a mathematically accurate description, therefore it must be right, even though it treats the measurement, clock rate, as more fundamental than what is measured, energy. To which I replied that epicycles were also mathematically accurate and he even pointed out that had they used ellipses, rather than circles, would have been even more so. In reality, one could make a Georginacentric model of the universe and with enough complexity, it would be as accurate as any other, even though the entire earth and universe would be swinging around your every move, because relativistically, that is how it does happen, because you are the center of your universe.
So even the most mathematically precision only puts a theory in the running for best description of reality. The point which choses the winner from the finalists is Ockham's razor. That which is most efficient. That's why we use a heliocentric model, not a geocentric model. It is most efficient.
So yes, make it as precise as necessary, but don't go overboard, or you lose sight of your goals.

is it confusing or are you just unfamiliar with it? The emphasis I place on time is because time is what its about. That is what I am talking about. Not culture, sociology, ethnic differences, consciousness or spiritual philosophy. Time is my focus and the terminology has been developed to unravel the temporal confusion that leads to the time paradoxes and unanswered foundational questions.
It has nothing to do with how Australian aboriginals or any other ethnic group deal with time. But the problems of physics specifically. I am not doing a sociological study of how different cultures interpret time.I am sure it has been done already and is of no use particular use to physicists.I too have read about isolated cultures who do not have any concept of time as we generally think about it. Interesting, but ultimately irrelevant here.
I am concentrating mostly upon the visual manifestation of reality as we are primarily visual creatures. To complicate the discussions by continually referring to all of the different senses would not be helpful. Though I have also mentioned the other senses and even non human senses.
If I said it like you then I would be thinking like you and not like me!! If you think you can answer any paradoxes or solve any physics questions by seeking out cultural differences and extracting them from consideration then go ahead.I won't hold my breath.
With respect. Georgina.

John ,
I think the construct of reality outlined is very efficient given the number of questions that "simple" alteration of interpretation can make. IE the alteration from considering reality to be only that which is seen/experienced as present-now, to also being the independently existing source of the data. Is there anything simpler that accomplishes as much without bringing in supernatural agents or realms? Not as far as I am aware.
I agree that the less said on peripheral matters the easier it is to sell the basic ideas. But ideas do not exist in a vacuum they have consequences and effects. It sounds bizarre because we have been taught that that image is the Universe but it just isn't the objects in space as they are, its an image reality. Which means there must be an object version. Lets say that is a prediction. When we get far enough out into space we will find things aren't where we think they ought to be or as they ought to be. Because the observed manifestation is not the uni-temporal object reality.
I will try to keep your good advice in mind.

Dear John,
"we use a heliocentric model, not a geocentric model. It is most efficient." Hm.
In my work as an engineer, I did never use a heliocentric model. Gravitation on earth and on moon is perhaps best described with geocentric and moon-centric, respectively, models. Just the explanation of motion of the moon relative to earth, of the earth relative to sun, of the sun relative to our galaxy, etc. (?) is more reasonable if we take an appropriate point of view.
Physicists like Lorentz and Michelson imagined the hypothetic medium of electromagnetic waves moving relative to the earth and could not explain why there was no experimental confirmation for that. Their rather elaborate attempts to find a way out gave rise to Einstein's speculations that are still not yet convincing to hundreds of scientists, a part of which signed the twin-paradox petition.
I wonder, why do proponents of new physics ignore obviously undeniable evidence for a largely geostationary medium of electromagnetic waves on earth?
Their ignorance reminds me of share holders before the crush in new economy.
While Einstein was perhaps often wrong, he was certainly correct when uttering: The stupidity of men has no limit.

Georgina,
I understand your argument and why it is necessary to keep it focused, but as you admit, you feel as though you are hitting your head against a wall. Having been in the same position, I'm basically thinking out loud about ways to step back and examine that wall.
Further up this thread I got into one of my usual discussions with Tom on the subject and he concluded by linking to the wiki articles on general and special relativity. I replied by posting the exact paragraph where it says:
"Such simple derivations ignore the fact that in general relativity the experiment compares clock rates, rather than energies. In other words, the "higher energy" of the photon after it falls can be equivalently ascribed to the slower running of clocks deeper in the gravitational potential well."
And I made the observation:
"My point has been that the clock rate derives from the energy, not the energy from the clock rate. This doesn't change the math, but it eliminates many of the exotic extrapolations, such as blocktime, wormholes, etc."
He simply cannot accept that anyone could legitimately consider that the geometry of spacetime is a model, not the fundamental reality and doesn't feel obligated to explain why, other than saying I just don't understand the math. So this is essentially the same wall you are hitting your head against.
The fact is that large sections of modern physics are built on this assumption of the geometry of spacetime as foundational to physical reality. Cosmology is the most obvious example, as the whole notion of space expanding from a point is based on it. Even many people who question established theory assume Big Bang cosmology as a given. So they will continue to ignore the idea of time as measurement, not geometry, because it does raise more questions than most people engaged in physics are willing to consider.
That's why there is a need to step back and look at it from a broader disciplinary perspective.
You have mentioned you are a biology teacher, if I'm not mistaken. Consider how important and interrelated time and temperature are in biology, as well as geology and many other fields where real change is a given, not an illusion.
Living in Baltimore, the local public radio station will bring on various experts from some of the local universities, such as Johns Hopkins, etc. Some years ago, they had on a neurologist, discussing the mind/brain dichotomy. I called in and made the point that if two objects collide, it creates an event. While the objects go from past events to future ones, the event goes from being in the future to being in the past and this is the mind/brain duality, because the brain, being physically manifest, goes past to future, but the mind, being a record of events, is going future to past. His first response was, "That's deep." then he started going on about how physics explains time as a component of space, at which point the moderator cut us off.
My point in telling this is that the nature of time is very important in understanding many fields, but that physics has established a monopoly on explaining it. So rather than taking on the physics establishment directly, given the stakes involved for their foundational models, there might be a way to get a foot in the door, through other disciplines. Especially if those engaged in those fields were to seriously examine the assumptions required of spacetime and not just assume it is too complicated to understand.

The geocentric model certainly does still have many applications, but the natural desire for clear story lines even extends to the history of science.
I've read interesting articles on how it was epicycles which laid the groundwork for the development of clock mechanisms and these were the original complex human built machines. The original example of how the desire for knowledge spawned technological advances far beyond the original intentions.

Time is not the fundamental delineator. Time is omnipresent. This does not help differentiate reality from (in your words) its manifestation, and, as said, I think this is where the confusion is creeping in. My point has essentially two strands: a) we are locked into a closed system of experience, that is our reality b) within that confine there is a separation of reality and and what we physically experience. Sociological concerns are a minor irritant in the experience process. I do not understand where you derived the notion of a Sociological interpretation of time from, I have not said anything that could be remotely translated that way.
To take one sentence from the several posts in the past few hours:
"However the Image Universe -does- appear to be spread over time as well as space, because data persists over time within the environment. So rather than there only being the singular existent arrangement of the universe, there are lots of potential -former- arrangements that might be observed".
This is incorrect. There was one, and one only, existent state that generated the 'image'. It might have taken one nano second, or 10 billion light years, for the conveyance of that reality in an image realisable form, but that has no effect on the reality. The "Image Universe", or preferably the sensory representation of reality, is not "spread over time", it just took a duration to travel. The longer that takes, the more likelihood there is that it will be affected by forces en route, but that is an entirely different point. Of course there will be more than one state, and one image, one might be able to observe this particular reality for 1 minute or 10 days, but the same logical point pertains to a sequence of states as it does to one.

I supopose it depends then upon what you mean by "culture etc etc." Perhaps you are using your own meaning of the word that has nothing to do with sociology.(?) And also that you are not talking specifically about time but generally about how people relate to reality. This thread is about understanding time. I have been talking about understanding time and giving the meaning of the words that I use, as I use them, to avoid ambiguity and misunderstanding.A helpful suggestion to have come out of the conference on time and shared in the video at the top of the thread.
People can interpret or relate to things however they like. (So long as they don't insist I must believe it or must do the same.) However the mathematics is the mathematics and only the correct solution will enable complete and correct -mathematics- of relativity and QM to be fully compatible without contradictions, paradoxes or other problems/questions.
What I said was not incorrect. It is how it appears to me when I think about it. I am not thinking about other peoples theoretical fantasies but what is observed. As for the image of the universe being produced in a nonosecond. That is an interpretation based upon the supposed expansion of the universe taken back to a point prior to time and space from which it all supposed to have begun. That is a theoretical supposition that I do not agree on. (It may be that the appearance of expansion is to do with the way in which the Earth object is moving relative to the unchanging origin of the radiation received. A trajectory at all scales not accounted for in the space-time/ block-time model.)
I am fitting the particular explanations given, with observation, basic well understood physics and biological processes, in such a way that the Grandfather paradox, and other paradoxes are overcomes and the foundational questions are answered. Without a space-time universe exploding from nothing in a nanosecond, without a fully determined unchanging space-time universe or, Multi-verses.It is not an interpretation that fits within, or needs to fit within, those aforementioned mental constructs but replaces them.
I would say -you- are incorrect when you say time is omnipresent. I would say the object reality is without time. I have previously tried using the term atemporal but now generally say unitemporal. That is to make clear that it is not spread across space-time, it is without time dimension.It exists -always- ahead of observation and all elapsed time from the temporal perspective of all observers.
- Not moving in time, not spread across time and with no time dimension.-
It is the observer produced manifestation, produced from sensory data, that is tied up with temporal complications. And that does not exist externally.
Don't come here and tell me that I am confused and I must think about things differently. Unless you can specifically tell me why the solution given does not overcome the paradoxes and does not permit QM and relativity to co-exist without contradiction or does not permit partial non determinism, and temporally unidirectional causality while still allowing relativity and non simultaneity.etc etc. Do you have a -better- solution?

John,
thank you for your last message. I agree that it might be useful to think about going on in other ways that are still compatible with the problem solving explanatory construct worked out, but are simpler to explain and comprehend. Your insistence on the direction of time has been very helpful. The temperature, a measure of the amount of change in spatial position of particles when looked at at a particular scale, might be a useful analogy.IMO; Despite Tom's reluctance.
Though importantly all objects do not exits just at the scale of the observer regarding them but have a microscopic and an object universal existence. The object consists of particles but also has change of position associated with the spatial change of the whole of galaxy in which it exists. I think it is this continual -total change in spatial position- of everything that is the connection of everything with complexity, and also the connection with the changes we observe and call passage of time. It is as you say energy, which is therefore comparable to heat which we measure at our scale as temperature.
Complexity is intimately involved in the whole conundrum. It is something that I have contemplated in the past but has been sidelined in the attempt to get a working explanatory model of time that is exact, precisely explicable, not based on speculation, and really works.
The temperature of a substance is measured with a thermometer by looking at the effect of the energy upon a liquid expanding next to a scale. We can not stick a thermometer into the universe at the object universal scale and note on the scale of the device the "temperature" of the universe.IE how much change in spatial position of constituents is actually occurring within it.So not directly comparable to temperature or achievable.But a helpful analogy, I think.
Humans make comparisons of the energy of objects from within the manifestation of space-time from the observers relative perspective at a single scale of existence. We can not even see the object universe as it is and physicist generally regard the image of the universe to be The (and only) universe (itself).So what is to be done? We agree that at that foundational level of reality, outside of the human observer's construct of space-time, it is energy, change in spatial positions that is occurring continually unobserved- giving observed passage of time. So one might say that -energy is creating observed time, though it (object universe) is not in time and does not contain time.-

please forgive my grumpy reply to your message. I am normally more patient and reasonable. The problem is that you have come upon my posts, which are to do with an exact explanation of time developed painstakingly over a number of years. Taken out of context the posts might not make sense. I took your messages as insulting to my intelligence and demeaning, when in fact I should have regarded them merely as a reflection of your incomplete understanding of what I was talking about or why.
Thank you for taking the time to write. It has been very helpful to me, as it is clear that the full explanation of the explanatory framework should be set out together as a series of papers or book that can just be referred to as required. I will then not have to rely on people having read and being able to follow my post, that have analyzed and developed the framework piece by piece here.
I have been thinking about the problem of time for over 6 years and was, to my shame, trying to inform mathematicians and scientists of the problem before it became the hot topic it is today. My initial attempts to form a working explanation have had to be binned as have subsequent unfounded speculations. Only those ideas that have stood the test of time and scrutiny remain and they provide the explanatory framework today. There is no confusion about it.
Kind regards, Georgina.

No, we can't stick a thermometer in the entire universe, but neither does a particular clock record all rates of change, but just as we could approximate a universal time by averaging all those clock, so too could we approximate a universal temperature by averaging the various levels of energy. Given the amount of space, relative to energy/mass, it probably wouldn't be much higher than the temperature of the microwave background temperature of 2.7k.
The idea of an expanding universe is based on the observed redshift of distant galaxies. Since this is directly proportional to distance, it is proposed that space itself expands, rather than this being an expansion in space, otherwise it would make us appear to be at the exact center of the universe. Here is a possible explanation for how light might otherwise be redshifted proportional to distance:

That's OK. I noticed your frustration before, and indeed (as Peter J will confirm) suffer them myself. It is difficult within the context of a forum. I also have a feeling that we are, more or less, 'on the same track'. Whilst I have read your paper (Peter J pointed me at it)I would not pretend to know your "full explanation".
So, let's start again. Specifically, re time (though ultimately it is difficult to separate that out from the fundamental logic of reality).
Time is an inherent dimensional quality of our reality. It does not exist as an entity, but is real as it is manifested through our experience of change to existent entities. Which implies there must be a dimensional quality in our reality for those processes to occur. This is similar to spatial dimension, where again, no entity exists. Our realisation of spatial dimensions being based on the experience of differences in existent entities and relative movement.
However, time is not a spatial dimension. Change does not necessitate space, as irrespective of the actuality, logically it always involves:
- sequence, which is a number of discrete states in a specific order
- rate, the speed at which any given state replaces its predecessor
So, at any point, reality only constitutes the last state of everything, as the previous state has been replaced and the subsequent one does not yet exist.
For example. If one 'froze' reality. [Which in effect is what is happening when a light based/air wave compression/etc representations of it are emitted, which we can then subsequently experience] Then one would still find the 3 spatial dimensions, because they would still be manifest in the state of the existent entities at that point. BUT, time would not be manifest, because there would only be one state of any given entity. So in that circumstance our ability to appreciate the dimension of time has been denied us. Now 're-freeze' reality some n units of time subsequently. Time is now realisable, because comparing states of existent entities reveals differences. Change has occurred. Not in everything, but the cat has moved, elementary particles have certainly done so, there is a noise that was not there before, but your monitor still looks the same and the leaves on the bush still appear to be the same hue of green. So,all exitent entities which comprise our reality change, albeit at different rates. Time is the dimension within which this occurs, but only one state in any given sequence of change exists in reality. Different states do not exist concurrently. So time is not a spatial dimension, it has, at any point, just one value.

Paul,
I have read your post carefully. Rather than dissect it I will try to explain briefly how the construct works so that you can see why I must disagree with what you have said. There are two different things going on together and that complicates matters.
There is passage of time which is a sequential change in the arrangement of the whole universe of objects and substance in space (not space time.) As you have said only the latest (or perhaps more correctly the earliest) version exists. The other versions having changed into the only existing arrangement. As they no longer exist they are just imaginings.
Reflected or emitted data from the objects in the existing object universe persists in the environment after the arrangement of the object universe has changed. It can be detected by different observers at different times (that is to say simultaneously to different existing arrangements of the object universe.)Giving relativity and non simultaneity.
The reality experienced by the observer is formed from the data intercepted and represents the objects as they were in the object universe when the data left it source. Not the existing arrangement of the object universe when it is received. Transmission of the data from source to observer takes time and so the object universe as it -is- always precedes observation of how it was when the data was produced. It might therefore be regarded as in the future compared to the experience of the observer. Light travels very fast so this is negligible for near objects but becomes significant for very distant objects or very fast moving objects.
Therefore there are two versions of reality. One formed as the output from received data input and the externally existing object universe which is temporally ahead of the images and experience of the observer which lag behind due to data transmission delay. This makes it necessary to differentiate and be clear about which version of reality is being considered as they are not identical.
The experienced reality, produced by the observer is dependent upon data input from the external object reality. It is prone to relativity and non simultaneity and is formed from preexisting data in the environment. So it is predetermined by that data.It has a time dimension.
The reality that exists unobserved is not prone to relativity or non simultaneity and is formed from continual change influenced by the overall effect all interacting variables and parameters within the object universe. Nothing but the existing uni-temporal universe precedes its new arrangement so its new arrangement is not predetermined but consequential.It has no time dimension. The object reality is independent of the image reality of the observer.
Both of the afore mentioned facets of the Entirety of reality co-exist.

Georgina,
There is no God's eye objective perspective and there is no God's butt to stick in a thermometer.
Singularities cannot collapse or expand space. Because space has no physical structure, its consequent properties are infinite volume and absolute equilibrium. Neither of which can be measured directly, even if they can be inferred.
We just have these cycles of energetic expansion and contraction.
I think we will come to realize that what are called black holes are gravitational vortices, like the eye of a hurricane. So the matter falling into them doesn't disappear into the black hole, but is ejected out as jets and bubbles of cosmic rays and radiation.
An interesting article on how close these rays appear to originate from the location of the black hole and not just its periphery:

John,
I was amusing myself by making the ridiculous absurd.
Being serious for a moment:According to big bang theory the universe didn't expand into space and time it made the space-time. What preexisted was nothing, no properties not even equilibrium, which requires something to be balanced and not volume because that requires something to fill the volume or something to contain the volume. So it wasn't and therefore has no description.
Enough of that.
I can image this as an entry in the "Hitchhikers Guide to the Galaxy". Pre-space-time: The ultimate blank canvas. So blank it has vanished completely and never was. Which made designing the universe rather tricky.
There can't -just- be cycles of expansion and contraction. There has to be Objects and media that can change spatial position or resist change of spatial position, and so be described as having energy. Or to be the things and stuff that provide the sensory data that can be processed and interpreted as things or stuff moving or resisting being moved. Disembodied energy with no medium of transmission is as ridiculous, but not as amusing, as measuring the temperature of the universe by sticking a thermometer up God's invisible Butt. By the way in reply to yours- I'm not God so I wouldn't know.

Georgina,
By cycles of expansion and contraction, I don't mean the universe as a whole, but radiation and mass/gravity. It was on first learning that gravitational contraction and the "expansion of space" had to be inversely proportional that I first began questioning big bang cosmology, because it made far more sense as a form of galactic convection cycle, where elemental mass particles condense out of radiant energy and "precipitate" into galactic vortices, until the density ignites it and the energy radiates back out, to start the process over again.
The background radiation emanating from the edges of the visible universe is not residue of the big bang, but the black body radiation of ever more distant light sources, that has fallen completely off the visible spectrum. I've been waiting since before the Hubble was launched, for them to find evidence of activity too old to be explained in the Big Bang timeframe, but the only reaction has been a scratching of the collective head as to how galaxies and galaxy clusters evolved so quickly. Currently the oldest observed galaxy is at 13.2 billion lightyears, which means it had to coalesce out of the inflation stage residue in only 500 million years. Since it takes our galaxy 225 million years to make one revolution, this would be like saying the time from the invention of the wheel to the development of the Model T, was about as long as it would take to drive two and a half times around New York City, to make a rough comparison.
Also, it makes no sense to say that space itself is expanding and then presume a stable speed of light to measure the expansion against. If space truly expanded, then so should this most basic measure of space increase proportionally. Yet if the speed of light increased as space expanded, then we wouldn't be able to detect it, as the light would be traveling ever faster to match the distance.
So there is some far more logical explanation for redshift than recession.
It was in trying to work this out that I came to the insight about time being truly relativistic, in that the events do not constitute a static frame, but move the opposite direction of the present. When I first began considering time, it wasn't as the present being the stable frame, but as the point of reference moving through its frame and causing everything it it to move incrementally in the opposite direction. Much as moving your finger through water causes a similar amount of water to move in the opposite direction. As in Newton's, "For every action, there is an equal and opposite reaction." It was in working this out that I began to understand how time is entirely a consequence of motion, not an external frame for motion. Thus my motion affects my reality to the same extent the larger reality affects me. Which makes the question of free will moot, as I am not free of effects, but am able to express the will that is me.
Space, infinite and absolute, is the frame for activity.

1 Time is not ‘a sequential change in the arrangement of reality’. Reality, or at least to be correct all the entities which comprise reality, change (at varying rates). We can experience that, and therefore appreciate, as far as we are concerned, reality has a non-spatial ‘dimension’ which enables this to happen (ie time).
2 It must be the latest state (version) of every entity that exists. Previous ones have been replaced, future ones have yet to come into existence. I cannot understand the meaning of ‘the other versions having changed into the only existing arrangement’. In reality, preceding states (versions) have ceased to exist. They are not ‘imaginings’, though sensory representations (data) of previous existent states may still exist.
3 Sensory representations (data) of any given state of any given entity do indeed exist (persist in the environment) independently and for long durations. And, in everyday life people do have a tendency to assume that what they experience a) directly represents reality, b) is all concurrent, and represents the present. But the whole point of science is to extrapolate the reality which instigated these resultant experiences, from a jumbled up translation of them.
4 There are not two versions of reality, in the sense you define, neither does the differentiation depend on timing. There is one reality. But we can only be aware of it via a spectrum of sensory representations thereof (data), which is selective because it is based on a medium, and then there are all the other variables which interfere. The time delay between existence in reality and receipt of a sensory representation thereof, being just one of the many variables to be accounted for. So we certainly have to be careful to ‘differentiate’ and ensure we are not conflating an experience of reality with reality. The process being reification.
5 There is a timing issue in the ‘experienced reality’ because the sensory representations (data), which are real physical phenomenon, have to travel varying distances in varying conditions. But the more we understand about how light (or any other medium) works, and the specific conditions prevailing, the more accurate we can get at estimating the actual time of existence.

Sorry if I am being pedantic, but time is not a consequence of motion. Our appreciation of it, and spatial dimension, arises from our experience of motion. By definition, motion must involve an alteration in spatial position (and we discern three possible directions), and motion involves change (in spatial position)so there must be a 'dimension' of time because we have a succession of existent states, albeit only one thereof exists in reality at any point. I am not sure about the infinite/absolute, we are constrained by our existence, but at least that invokes a closed circle for us within which we can explore reality as experienced by us. So we can have 'absolutes' within that limitation.

John,
Thank you for sharing your points of view.
Re time: I agree that time for us is to some extent a consequence of our own movement. We determine the events that make up the passage of time that we experience by choosing our spatial locations. Thats also what Wilhelmus was saying about free will and a unique life path.
It does take the living organism observer, that is able to move around, away from being a mere passive recipient of predetermined sensory input supplied by the universe; because the organism is choosing location and thus -which- prewritten sensory input will be received. Unlike the inanimate object or device set at a fixed location. That is an interesting point of difference that you have both identified.

Hi Paul,
I will address your numbered points one by one.
1.Sequence is not the same as fixed or uniform throughout. If I have a lot of balls on the floor of a box that are touching and I push one of the balls the other balls will have to move also to accommodate the movement of the pushed ball. Some balls may move more than others but after the push the balls are in a new arrangement than before. There has been a change from one spatial arrangement to another in sequence. Arrangement 1. becomes arrangement 2. The sequence of the arrangements is nothing to do with how much the individual balls move or don't move. Push a ball again and the next arrangement in the sequence 3.will be formed. The sequence of arrangement is 1,2, 3, where to or how ever much the individual balls shift.
2.If the sensory data required to be aware of something has not yet arrived but it will later on, that which has not yet been seen is in the "will be" observer's future. That which has already been observed is in the observer's past from the observer's perspective. Hence it is the earliest/youngest arrangement that exists. The previous arrangements having been recycled into the "youngest" version. This is providing continual -new- input into the (potential sensory) data pool and giving temporally unidirectional causality and passage of time.
3.OK
4. This is a matter of description. Yes there is only one Entirety of reality but within that there is the output from processing of sensory input which is a manufactured representation. Therefore I choose to describe them as different facets of the Entirety of reality. One I call the object reality the other the image reality. They were on the list of definitions I gave. The photo of a cat is not EM data reflected from a cat, or a living cat organism. Photo=output, reflected EM=Input, Cat= Source of input. But as you point out and I agree all are reality, in their own way.
5.Its actual existence as it is, is always ahead of every observer's manifestation of reality regarded as present-now. Thats when it is. Temporally ahead of observation. Everything that is seen/experienced within a present now is formed from data from events that have already occurred.It is not as easy as it sounds to say when something was because of non simultaneity within space-time. Knowing that very accurate timings can be made and potentially more can be learned about transmission of data and affects upon it.

John,
The experiments I mentioned found an ether that moved together with earth relative to the sun except for sharing the earth's rotation. So I should perhaps not use the denotation geocentric.
While I am not an expert in this field, I see this revelation an intriguing alternative to so far otherwise explained experiments which led to special theory of relativity.
Shtyrkov considered his experiments a (failed) test of the latter. As a serious scientist he avoided to draw attention to the due consequences in a sensational manner. He cautiously wrote: "Evidently, this fact is reason for the hypothesis of light speed constancy WITH RESPECT TO THE OBSERVER (in Proc. of the NPA emphasis expressed by small bold letters) to be revised."
I already also mentioned Persson, and Gift. Recently Norbert Feist suggested: Detecting the Ether Wind by Doppler-Radar. See also Doug Marett.

May I proffer that 'Geocentric' is correct, or ECRF (Earth Centred Reference Frame) to be fully astrophysically correct with respect to NASA, GPS etc. This does not however make the Barycentric (or Heliocentric) frame incorrect. (Inside the Heliosheath shock). Each collection of protons ('body' or collection of bodies) has it's own dragged field. The Russian paper was correct, consistent with Gravity Probe B's Geodetic drag, and Stokes 'Ether drag.' Every planet has an ionosphere and shock, as Venus express recently showed. The thin pour brains find difficult to envisage is the fact that they may be inside each other. i.e. there are background frames but they're not 'absolute' frames. This is precisely what the DFM shows.
This not only matches all the evidence... (here are just 2 papers;) Hewish A., Bragg L., The Diffraction of Radio Waves in Passing through a phase-changing ionosphere. PRS. Vol. 209, No.1096. 1951 http://www.jstor.org/pss/98862

...but is fully in accordance with Einstein's conception that bodies are not 'IN' space but are "spatialy extended" and there are "infinitely many 'spaces' in motion relatively" (1952)
This resolves the speed of light being limited to c for all moving observers if they are made of bunches of protons, (with fine stricture electrons around them). If any moving observers are NOT made of bunches of protons however, then I have to agree that the DFM will be proved false.
Do you have any links to English translations?.

The point I keep making about why time seems confusing is that our cognitive functions are based on that sequential series:
"Our appreciation of it, and spatial dimension, arises from our experience of motion. By definition, motion must involve an alteration in spatial position (and we discern three possible directions), and motion involves change (in spatial position)so there must be a 'dimension' of time because we have a succession of existent states, albeit only one thereof exists in reality at any point."
Yet the actual physics does not involve the present "moving" from one state to the next, but within the present, there is a change of configuration, such that what is physically happening is not that the present moves from past to future, but the events transition from future to past.
Does the earth really travel a fourth dimension from yesterday to tomorrow, or does tomorrow become yesterday because the earth rotates?
When you view it as the former, yes there is that narrative dimensionality of the timeline, but when you consider it in terms of the latter, then the series of different events is an effect of the changing configuration of what physically exists as what we call the "present."
When clock rates differ, due to physical input, it doesn't mean one clock is traveling along that dimension of time faster than another, but that one is recording a faster rate of change, due to a more energetic level of activity. Thus when the twins meet up again, one may have aged faster, but only due to an elevated metabolic rate, due to a higher level of atomic activity.
There is no need for multiworlds either, due to quantum probabilities, because it is the collapse of such probabilities, the future potential, which creates present events and then replaces them.

Certainly they don't walk to the office, or the pub, or the rugby ground. The plants are also complex organisms able to respond and move in response to the stimuli in their environment. I even read in New scientist about a plant that releases a chemical that summons ladybird beetles for assistance, when caterpillars are eating its leaves.
In Australian aboriginal culture the landscape is tied to personal stories that are shared and passed down generations.By walking the landscape, and identifying the features and characteristics of the places passed through that person is then able to narrate the tale of the journey in detail. Memory experts tell us that it is easier to remember lots of information, especially lists, if the information is connected in some way into a story. These mental maps can be referred to when navigating. The places brought to mind then are not points within a spatial co-ordinate system on paper or computer screen but part of an individuals life journey, one of those unique life paths that Wilhelmus mentioned.

Georgina,
I'm not knocking plants for not having a central nervous system, but commenting on how motion defines our existence.
In discussions with Jason, over his desire for faster than light travel, I point out that speed is another form of limitation, in that the faster we go, the less ability we have to maneuver, or connect.
Probably if plants were able to intellectually express themselves, they would view temperature as much more fundamental than time, as it is the constant change of temperature which dictates their temporal cycles. Plants are very non-linear.
Our intellectual function is primarily a recording of the sequential function, both in the stories we remember, record and transmit, as well as the cause and effect processes which underlay the sciences.
Would a plant look out across the cosmos and think there exists some timeline, from birth on, that explains it all, or would it see those stars and galaxies as flowers in a field, the points of attraction in an endless network?
The function of our mind is to distill out the useful information from the endless amount available, so it is this distillation process that so defines our appreciation for reality, as we constantly search for meaning, as though it were the perfect berry on a bush. Now we are constantly trying to distill ever more abstractions of value from our reality; metals, jewels, instruments, abstractions of wealth and value. We want them because they appeal to that foundational sense of focus and attraction that is our means of survival and the sense of purpose it gives us.
Is this focus foundational, as we assume with our search for Gods and theories of everything, or is it just a conscious manifestation of electromagnetic and gravitational attraction, eventually kept in check by forces of repulsion and radiation?
Something to consider, as this worldwide Tower of Babel crumbles. What will rise in the eventual rebirth?

Re your post 10/9 10.15. Time is not to any extent a ‘consequence of our own movement’, or indeed any other action. We cannot influence time, just like we cannot alter any existent aspect of reality. In your words, the living organism is still a ‘passive recipient of predetermined sensory input’. It just happens to occupy a different spatial position from that which it could have done, at the point of reception of the sensory information. It has the free will to be in any spatial position (within reason!), but that just means there is a variance (eg time delay) in whatever would have obtained in an alternative circumstance. The organism cannot occupy different spatial positions and receive the same sensory representation of the same state of reality.
Re your post 10/9 11.24.
1 The sequence is the number of discrete states, in an order, which comprise a particular example of change. There is then a rate at which states replace their predecessors, which could vary from state to state in any permutation. The totality of durations for each state, obviously equals the total duration of the sequence. Example: cat walks across garden. That could be decomposed into a sequence of states. Note that during this event, it will also get older, its molecular structure will alter, it claws grow, moult some hair, etc, etc. But we are interested in the sequence of change in reality associated with its progression from A to B. It is doubtful if each state will elapse with the same duration, it will probably stalk to begin with and then make a dash for it. I couldn’t understand the relevance of your example about balls.
2 Obviously sensory information which has not yet been received is in the observer’s future, assuming that he/she is in a position to receive it. If they happen to be looking the other way, or a brick wall is in the path of the light, then…..Equally obviously, something that has been observed is in the observer’s past. And all this is in terms of observer perspective. But this is not reality. As above, reality went through a sequence of existent states, each of which resulted in the emanation of experienceable information. How people process this stream of information, I don’t have a clue about. I will leave that to people that do. It is fascinating, one gets a good programme every now and then, particularly where people have suffered some specific brain damage, or indeed there was the blind bloke recently who had learnt to echolocate.
4 As I said above when picking up a post I missed, there are two existent states which we have no influence over. It is not a ‘manufactured’ representation. That is the point, it exists BEFORE we/other organisms enter the process and ‘muck it up’(!) even more. I turn round and there is my dog. I am aware of him, because a) he is an independent existent entity, b) light emitting from him has enabled this. Then, and only then, do I come into play and interpret the information. I realise what your labels refer to, but personally, I see no point in an adjective preceeding reality. It is just that, reality. And I have looked at your definition of Image Reality, this being the output from the process of experience. Again personally, I would not deploy the word reality here. It makes what is actually a jumble of translations seem more ‘official’ than it is. This is what we start with, but it’s a mess.
5 I do not understand your point, and do not want to get involved in simultaneity/ relativity. Go back to that cat. Assume no relative motion, and lots of other things which enable us to have articulated experiences and only the raw light based representations. We have a man and his dog, a few metres away. Another the same distance but behind a metre thick glass wall, an eagle several thousand feet up overhead. A bloke on the moon, another in a strange gas cloud/aquarium of water, etc, etc. Now, with the right understanding of the processes, all these observations could be regressed and would arrive at the same definition of reality, ie cat by point in time by specific point in space.

Re your post 10/9 17.27
It certainly is confusing, and I did say ‘I might be being pendantic’.
However…wrt your sentence “but within the present, there is a change of configuration, such that what is physically happening is not that the present moves from past to future, but the events transition from future to past” In reality, there is, at any point, only the present. It is the result of a change from the previously existent state. And in due course (very very quickly if we are considering the motion of elementary particles) it will be superceeded by the next existent state, and cease to exist.
The earth rotates, for a reason, in a duration. There must therefore be time. That is reality. Perceptions thereof, and how people may wish to translate them, are different.
I agree with your point about the twins, etc, which again is why I used the caveat of pedantic. Time in reality cannot be altered. Moreover, if the logic of reality is one existence, independent, we experience, etc, etc, then QM has a fundamental problem. Just for a laugh, if you follow the QM vision as to how reality operates, then Schrodinger’s cat would have ‘caused’ reality to occur. A human opening the box later, with or without a friend, is irrelevant, because the event has already occurred. But as with most philosophers, non-human organsims seem to be denied their right of experience. Which in terms of consistency is invalid. That little dog I mentioned in a previous post (Ralph), shot off downstairs several minutes before the postman actually arrived and I heard his foorsteps.

Paul,
"The earth rotates, for a reason, in a duration. There must therefore be time. That is reality."
Why is it not argued there must be a physically real temperature scale? There certainly is a bottom end to the scale, ie, absolute zero and there are certainly quite a few independent lines on the scale, freezing, boiling, ignition points, etc. Yet we don't see temperature as fundamental, but an emergent measure of various interacting elements.
I would say time falls in the same category. In fact, in terms of measurement, temperature is more obvious, since there presumably can be a level of activity, without a perceptible change of state.
When the argument is made that there is duration, therefore time must be real, but what is duration? It is not as though the starting and stopping points coexist, as points in space can coexist, since the physical processes dissolve one in order to manufacture the other out of the same constituent/present energy. There is no universal measure of duration, as relativity shows that environment will change the duration of a given process. Just as changing environments will change freezing/boiling points. When we measure duration, we are measuring a physical process, just as when we measure temperature.
So I will certainly agree time is a real phenomena, but in the same sense that temperature is a real phenomena.
The reality is that we have a bias towards time, because our rational mental functions derive from the temporal vector of cause and effect narrative memories. Consider though that the concept of spacetime isn't based on all aspects of space, but specifically of direction/distance. Volume is an equally necessary non-linear concept of space, of which temperature is closely related. In fact one could use ideal gas laws to argue temperature is another parameter of volume, much as the properties of light are used to correlate distance and duration to make spacetime. Specifically that changing the volume of a given amount of gas will have an inverse effect on its temperature. So why doesn't anyone talk about spacetemperature?
Basically because we understand temperature is a property of activity, not some topological basis for it.

I'm afraid it depends upon what you mean by "time" and how you define "reality", ie how/why you think time occurs and what you think reality is. Within your personal understanding of time , which I think is inadequately considered and your personal opinion of reality then you may be correct.The time experienced by the individual does depend upon the sensory data received because it is that data that is forming the present now-manifestation of reality.It depends on other things too such as speed of processing of the information , state of alertness, whether it is a life threatening situation.
Addressing your numbered points:
1 Pity you didn't understand the balls. The point was passage of time is about change of the whole universe simultaneously and not comparison of how one object changes position relative to another. Not how an observer measures an isolated change from his reference frame at his scale. It is the whole pattern of the object universe changing at all scales.
2 Obviously? Really? Good. You said "If they happen to be looking the other way, or a brick wall is in the path of the light, then..." Yes they do not see it. But that does not alter its independent object reality.
You then say -"Equally obviously, something that has been observed is in the observer's past." Glad it is obvious to you. Though I do not know what you think "the past" is. So we might actually be disagreeing on this point
You then say "And all this is in terms of observer perspective. But this is not reality."
If it is not reality then what is it? If you look in a dictionary it will most probably define reality as being that which is -seen-to exist, amongst other things. I have given several dictionary definitions of reality on this site as well as definitions of the terms object and image reality as I am using them. If we don't even agree on what is and isn't reality then it will be difficult to fully agree.
You said " ..... there are two existent states which we have no influence over. It is not a "manufactured" representation. That is the point, it exists BEFORE we/other organisms enter the process and "muck it up"(!) even more." Here you are misinterpreting my description of image reality from processing received data with the independently existing object reality. That is just misunderstanding.
You said "I turn round and there is my dog." No I perceive that there is my dog from the information received. I do not see dog object but observer constructed manifestation produced by my visual cortex using input data and memory conserning said dog.A fabricated representation.
You said " I am aware of him, because a) he is an independent existent entity, b) light emitting from him has enabled this. Then, and only then, do I come into play and interpret the information. I realise what your labels refer to, but personally, I see no point in an adjective preceeding reality. It is just that, reality."
Thats the problem, you do not see the point. It is -essential- that the output reality from sensory data is not equated to the source of the input as they are not identical. This separation of the facets of reality allows the Grandfather paradox to be overcome because it can be found from this separation that the time dimension only pertains to the manifestation output and not the source of the input.
You said "5 I do not understand your point, and do not want to get involved in simultaneity/ relativity." I'm afraid there is not much hope understanding how time woks if you don't want to think about relativity and non simultaneity. They are intimately involved in the conundrum.
And finally You said "........... all these observations could be regressed and would arrive at the same definition of reality, ie cat by point in time by specific point in space." Alas, if only it were that simple.

John,
Re temperature. Go back to balls in the box analogy. There are two kinds of change going on simultaneously it seems to me. One is the change of position of everything together at all scales, whether the orbit of a satellite or the rotation of galaxy or of an electron. Thats the pushing the box along the floor. No choice about it everything goes together what ever scale it is at. Nothing can be left behind as everything is moving. Two fermions can not occupy the same space at the same time. And there is only 1 time here.If everything is moving everything has to get out of the way! Its as if the whole pattern has undergone rotation at all scales but apart from that is unchanged.
The other kind of change is the amount of change of individual objects within the universe. Which is how much the pattern of the universe itself has changed rather than just moved. Thats what happens when a ball is given a push, a force is applied, and the universe has to respond. The other balls have to move to accommodate the change of the pushed ball. This is the temperature component that you are talking about imo. The higher the temperature, the greater the changes of position of individual objects. The more change occurring, the more the overall pattern of the universe changes in that region, as the continual change of everything continues. High temp., lots of energy, lots of change , lots of alteration of the pattern. Low temp., less energy, less change, pattern remains and moves to new position IE is also present in the new iteration of the object universe.
I don't think the two different kinds of change can be separated out and one is the absolute time and the other isn't as they are occurring together as one complete process of transition between object universal arrangements/patterns. Arrangement1. arrangement2. arrangemt3.....

Georgina,
Yes, time and temperature cannot be physically separated, but the problems arise with how we conceive them. For one thing, we think of temperature as a dynamic. What we are measuring is the level of action. It would make no sense to try to consider that exact position of every molecule, since it is their motion we are measuring. On the other hand, with time, we try to mentally freeze frame the action, since we are trying to measure from one exact position to another. This mental conditioning eventually leads to static spacetime geometry.
Since a particle cannot be isolated from its motion, the idea of an exact position is moot. Which places limits on really exact measures of duration.

John,
I suppose we are back to the question of whether the change of patten and pattern rotation is continuous or digital. Whether there is a minimum possible amount of change. Perhaps there isn't, and whenever it is thought to be as small as it can get there is a smaller scale to consider. Thats how it seems to be with fractal patterns. Pattern within pattern, within pattern at smaller and smaller scales.
Who knows what exists at such a tiny scale. Perhaps a pattern in free quarks within the medium of space, and beneath that within fragments of quarks....There are however minimum possible detectable changes, like the photon which I think is the minimum detectable disturbance of the medium of space caused by change in position of an electron. So the model ought to work down to that digital limitation. As otherwise it will have to use imaginary changes for which there is no evidence.
That is not to say that it is a digital object reality but that it can not yet be shown that it is not. Any change so small that it is unmeasurable/undetectable and has no discernible effect may as well be regarded provisionally as no change.I don't think it is what individual subatomic particles are doing that gives passage of time but what the whole universe is doing at all scales. Not those those minuscule sub atomic changes alone but the rotation, continuation and alteration of arrangement/pattern of the object universe as a whole.

John,
you know its that quantum physics dilemma at the universal scale. Its a choice between position or momentum at the subatomic scale and at the universal scale it is a choice between spatial pattern/arrangement of the universe or energy/change of arrangement. Either a pattern can be considered or the transitions but they can not be considered as the same thing at the same time, even though in nature they are inseparable.

Georgina,
True enough, but there are practical effects of whether we consider the measurement as fundamental, or whether what is being measured as being an effect of something fundamental. The notion of an expanding universe is built up from the assumption that photons are indivisible particles, rather than the smallest measurable quantity of light. Thus assuming they travel as particles and can only be redshifted by recession of the source, rather than as the sampling of a wave front that has been continuously expanding from the source.
I think the issue of the Higgs field will be a test of whether everything, even inertia, can be quantized.

Your post 12/9 17.33
If I understand your question re temperature correctly, then the answer: because, even within the confines of our existence, we have no way of fixing an absolute for attributes such as temperature (or movement etc). They are all pervading, ie every entity exhibits it. So we can only establish temperature by comparison. When measuring this, or any similar attribute, what we are actually doing is saying A is different to B by Z units. But temperature is a real existent phenomena, that is why you can feel it.
Time is not of the same type as temperature. You cannot see, hear, feel, or in any physical sensory way, experience its existence. It has no existent state. What you experience is change. The state of an entity changes. As you know that one state must precede another, or only one state can exist at a time, then we can logically appreciate that our reality has a dimension to enable that. Duration is time, and this is not a point about relativity. Going back to earth rotates, one can express this, not in terms of time, but with comparison to another example of change. Example: whilst the earth rotates once, the average conifer tree grows 1mm in height. We are comparing change. Indeed, we could run the entire system in terms of conifer growth. That would be logically valid, just not practical, because conifer growth is not particularly constant and its frequency of variation is low. And it would be damned difficult to carry your own personal conifer (clock) around!!
In terms of perception, we certainly have a ‘bias’, or whatever other word one wants to use. We’ve evolved over millions of years. But science is supposed to differentiate reality from perception (deep seated or otherwise). In your comment about volume/gas/etc, you are confusing cause and effect. Measles has an effect, ie spots. We can define these and identify both the disease and its progress. But, if we get something wrong re symptoms, that does not alter the actual pathology of the disease. Neither is anyone suggesting the spots are the disease.

1 It’s not a case of personal opinion. Time, as a dimension of our reality, exists, independently of us, so we cannot influence it in any way. Reality exists. My house exists, no amount of perception by me, or any other organism, will change its existent state. As I said, the time delay, between existence and realisation thereof, is dependent on the variables in the process. I don’t understand what point you are making there (assuming it is meant to be different to something I have said). One is the time as at existence, the other is the time as at realisation (however that is specifically defined).
2 I still do not understand your example with balls. Ultimately, one could argue that everything must have a connectivity with everything else. Whilst logically obvious, I am not sure where this can lead. This morning somebody, somewhere, chopped a tree down. Now, by tracing trillions of interrelated events I could probably, ultimately establish a connection with some impact on me. So? One has to deal with valid closed systems. There is no known connectivity between the act of fishing and plumbing. So someone can go fishing without this knowledge, they do however need a rod, etc, and to know where the river is, etc. But this may not have been your point.
3 I think one can safely say that the fact that the event has to exist before we can experience it is an ‘obvious’ statement. The answer to your question [“If it is not reality then what is it?”] is that it is perception, (or whatever one wants to label it, so long as its definition has a correlation with reality).
4 My point about the dog, and expressed elsewhere, was that there are two states before any organism is in anyway involved in the process, ie a) the existent state of reality, b) sensory representations thereof. We cannot see anything if there is no light based representation available, and that cannot exist if there is no reality. I’m lost as to how you think I am failing to see the differentiation of the various ‘realities’ (whatever label is applied), because it is precisely what I keep on about. But this might have something to do with the conceptualisation of time
5 In terms of relativity and simultaneity, I was trying to not generate a whole other debate. However….please read the following references first, then tell me how time ‘fits in’.

Paul,
"You cannot see, hear, feel, or in any physical sensory way, experience its existence. It has no existent state. What you experience is change. The state of an entity changes. As you know that one state must precede another, or only one state can exist at a time, then we can logically appreciate that our reality has a dimension to enable that. Duration is time, and this is not a point about relativity.
As I keep pointing out, we do perceive one state preceding another, but does the present move from past to future, or do those states go future to past? To repeat a previous example of the question, does the earth really travel that dimension from yesterday to tomorrow, or does the constantly changing situation, including the rotation of the earth, turn tomorrow into yesterday?
I can understand that when one views time simply as the linear progression from one event to the next, time does have the appearance of such a vector. It's the conceptual basis of history and all such narrative by which we define ourselves, but is that timeline physically foundational, or an effect of more foundational processes?
I rather suspect that if you told the average person of a thousand years ago, that the earth is rotating relative to the sun and not that the sun moves across the heavens, they would look at you as if your head was on backwards. Obviously the sun moves across the sky!!!! What world are you from? Haven't you stood outside and watched it come up in the east and set in the west? The fact is that is how we do perceive it, even today, but know we know it is because it is the earth rotating not the sun moving.
Now above, you make the observation; "As you know that one state must precede another, or only one state can exist at a time, then we can logically appreciate that our reality has a dimension to enable that. Duration is time." What you are saying is that obviously time is movement from past to future.
That is what we experience, just as we experience the sun moving across the sky from east to west, but what causes this experience? Does the present moment move along that dimension? Or does the physical activity cause transitions within the present? If you can accept that it is really transitions within the present, then that "dimension" must exist within the present as well, but only as memory and projection.

Paul,
It is not a "whole other debate" to bring up time's place in mathematics and physics, it is quite on point and important to understanding just what time fundamentally is. I believe you have placed far too much importance to the human sensory angle, too many attempts to "strip away" what is actually more important. I do not think you can form an equivalence of sorts between the reality of time and the reality of one's tush "in a chair", a river, your dog, etc. etc. Time is a bit more ethereal than that.
After you "strip away" what I would consider the more important issues, you are left with nothing more than the obvious, that all of us understand as human beings, perhaps not so appropriate for this blog dedicated to fundamental issues in math and physics.

Paul,
1 You said "It's not a case of personal opinion. Time, as a dimension of our reality, exists..." Statement of your belief.If you mean by "our reality" that which is experienced then I agree. You then said "...independently of us, so we cannot influence it in any way". The time dimension does not have independent existence in the object universe but is formed by the observer observing. It exists only in the output reality. It depends upon the observer observing and the perception of the observer can be that the passage of time is variable according to input data. It is the path through space that influences what data will be input to form each present-now experience.
The variable speed of passage of time according to observer perception is not a part of the model under discussion, though it might be considered as an extension of it. It is certainly not incompatible. Variable passage of time is a part if the reality experienced by the observer and therefore should not be denied its factual occurrence, on the grounds of incorrectly applied theoretical ideas.
There are two things going on. Passage of time due to change of arrangement of the independently existing reality and relativity in space-time due to the temporal artifact resulting from data transmission delay.
2. You said "I still do not understand your example with balls." It is a model of what is happening at the foundational level of reality and has come from the descriptions of how time occurs, that are being used.
You said "Ultimately, one could argue that everything must have a connectivity with everything else. Whilst logically obvious, I am not sure where this can lead."
"OK the balls in a box are an analogy. So not actually what is going on but a concrete way of thinking about an abstract idea. It goes with a model that allows a partial non determinism and so some free will. For that to happen there has to be an -unwritten- future coming into being. Thats what the balls are representing. With this going on -as well as- the transmission of EM data producing the space-time experienced reality, it is then possible to have both relativity and non simultaneity but no Grandfather paradox. Also pre-written futures (sensory data in environment ) but also free will and uni-directional causality and one way time.Its actually a big deal.
You said There is no known connectivity between the act of fishing and plumbing."Certainly there is a connection if the fisherman is a plumber and he misses my appointment because he is out on the river.
3. You said "I think one can safely say that the fact that the event has to exist before we can experience it is an "obvious" statement.""OK though I would prefer "had to have occurred" as it then ceases to exist as an arangement of the object universe and only the sensory data produced from it remains in the environment.
You said "The answer to your question ["If it is not reality then what is it?"] is that it is perception, (or whatever one wants to label it, so long as its definition has a correlation with reality)." OK as I was saying then "Image reality". That is what I want to label it. It shows that it is still a part of reality, agrees with people who consider what they see to -be- reality; but differentiates it from that which exists independently from the transmission of sensory data and observer experience.
4. You said " My point about the dog, and expressed elsewhere, was that there are two states before any organism is in anyway involved in the process, ie a) the existent state of reality, b) sensory representations thereof. We cannot see anything if there is no light based representation available, and that cannot exist if there is no reality. I'm lost as to how you think I am failing to see the differentiation of the various "realities" (whatever label is applied), because it is precisely what I keep on about. But this might have something to do with the conceptualization of time."
OK. I think we are agreeing on the basic concept of an observer independent reality but you are not clearly differentiating between source of input to observer- and output. It may seem a minor and irrelevant point but it is very significant for answering the foundational questions and overcomiong the time paradoxes.
a)the existent arrangement in space independent of observer perception.- Dog object. b)The EM data reflected from dog in data pool within the environment independent of observer - Potential sensory data. { a) and b) are the independent reality, called Object reality, by me.} input-[ REALITY INTERFACE ]-output c). The observed output, produced -by the observer- from received data input, temporally delayed and otherwise altered by the process -the Manifestation, -experienced- as existing in external reality - Dog image reality output.
5.You said "In terms of relativity and simultaneity, I was trying to not generate a whole other debate." Good. We experience reality due to receipt and processing of data, that has been transmitted but with non infinite data transmission speed. So there is a temporal component of the experienced reality resulting from that. Therefore relativity and non simultaneity are a part of the output image reality.
Paul thank you so much for taking the time to consider these ideas.I really do appreciate it. I am sorry to disagree with you on so many points. For the model to work to answer the foundational questions and overcome the paradoxes it has to be precisely understood and applied. To ensure that it is precisely understood it is necessary to be pedantic about the language used and the way in which temporal terms are applied in particular.

I think this is important because there is a problem with QM not scaling up. Here however something seen in QM -is- scaling up to the object universal scale.
Also the very fact that it is not possible separate change from the pattern it forms or vice versa, and have them existing independently is important, I think.
It means that particles really ought not to be considered as zero dimensional points. Something which Eckard feels strongly to be a mistake from a mathematical viewpoint. I think he is correct because the zero dimensional point vanishes where as what we have is something in transition between those imaginary zero dimensional points. A minute 1 dimensional line.If you make the line so small it becomes a one dimensional point the realism of the model has been destroyed; because it no longer represents the energy component and the transition. So that it is made from hypothetical particle lines not points is as important as the pattern.
At each step in the sequence the line has moved but might be considered to touch or overlap the line of the previous step. Now the becoming, the energy, is included in the representation of what is. It does mean that the position can not be absolutely defined but it would seem that absolute position is incompatible with a universe where everything is locked into perpetual change, moving on and becoming.
Superposition in QM may be confusing the desire for a static absolute position of an object with a continual change, as the arrangement of the universe continually alters at every scale. Where a particle is detected will depend upon the arrangement of the universe, at that scale, when the detection occurs. It is only observer perspective that makes some things appear static and others to appear to be in motion. The earth is moving and so therefore is the cup on my desk. It is that human perspective that drives the desire to give things static measured positions in space-time.
Everything must be changing spatial position. Like the balls in the box. Shift the box and everything goes together. Move one and the others must accommodate the change. Everything is changing position faster at that tiny scale. There is a lot of energy, accentuating the changing of position; but it is not different from what is occurring at the larger scales just faster. Larger objects move more slowly- but they have more inertia, more resistance to change of trajectory. (So scale is not just about size but amount of change occurring.)
Then quantum de-coherence is an observer imposing a static viewpoint of position/state of being from received data/detection. That reality being formed from the detection/received data. The reality -imposed by the observer- only comes into being upon detection but what was, which may have been more variable over time/change of arrangement of the universe, still had reality in space independently of the observer. Spread not over a Multi-verse but different iterations of the Object universe, existing and then being superseded in sequence.

PS. Wouldn't be right to join all of the minute lines into strings because only the youngest of the sequence exists.IE where it is within the existent arrangement/iteration of the object universe,so not including any former ones. Though such a string would be an imaginary historical path through space of a single object.

Georgina,
That's very much my view as well. Consider:
"It is only observer perspective that makes some things appear static and others to appear to be in motion."
The implications of this. Think in terms of a camera, where the faster the shutter speed, the clearer a moving object appears, but the slower the shutter speed, the more its motion is chronicled. How different is than saying that both position and velocity cannot be measured at the same time.
The moving object appears smeared out and not as substantial than the static object, yet they are obviously the same object. It is both wave and particle.

1 We are aware of existent states succeeding one another. Previous (the past) states precede the current (now) state, which exist before those states which have yet to come into existence (future). Assuming the medium conveying this information to us has an adequate frequency and a reasonable consistency of travel, then our perception will accord, fundamentally, with this. In other words, in the information we receive the states will be in the order that they existed in, and, at least, we will be aware of a substantial proportion of the existent states in that order. If not, given known experience, we could re-order the received states and/or fill in the gaps.
2 People can view time in any way they want to. It is its existent reality that is important. It is, to use your words, ‘physically foundational’. It exists, as a dimension, independently of us, we are aware logically of its existence because entities change in state.
3 Your next example proves my point. For very understandable reasons, based on lack of information, or deemed connectivity between entities which are not actually existant, etc, etc, people can come up with depictions of reality which are not in accord with it. But they are depictions/perception/whatever, not reality. Indeed, in existential terms, science can only ever be a ‘depiction’, but the aim is to ensure it accords with reality as far as possible within the limitations of our existence.
4 There is only one present moment, so it does not ‘move’, neither can there be ‘physical activity within it’. We experience the sun in a series of spatial positions which indicate that wrt……etc. But this is all about spatial position, spatial dimension and movement, not time. It is purely the fact that the sun has changed, in this example in terms of relative position, which indicates time. There is a change in existent state. The fact that it glows at different rates of brightness is another indicator. Change has occurred.

"My hunch is that this ability of the system itself to grow new parts is a fundamental aspect of the nature of spacetime and the vacuum that we have so far missed in physics," explains Jacobson, a physicist at the University of Maryland, College Park.
Armed with a $82,127 grant from the Foundational Questions Institute, Jacobson is now working on that hunch to address two basic questions: How can we modify the laws of physics to allow for this growth, and could we possibly see signs of this underlying discreteness in weird phenomena such as dark energy?
I see some correspondence between what has been discussed in these recent posts with the view expressed in the paragraphs above. There must be new arrangements of objects and substance coming into being, (though not directly into space-time but in space).That component of the explanatory model is necessary , it gives the open future necessary for temporally "uni-directionl" causality, "uni-directional" passage of time and potential free will. Yes so far missed as the space-time continuum has been assumed to be complete from beginning to end.

Paul,
do not concern yourself with the human sensory angle if you think it complicates matters or is irrelevant. The different facets of reality also apply to artificial detectors. Source of input is not identical to output. That is the important matter. Yes it is all reality, but to answer the questions and overcome the paradoxes the differentiation between that part of reality which is the source of input and that part of reality (the output) created from change occurring when data is input, has to be made. The human sensory angle is just being used because that is what we experience. The structure and function of living organisms is more familiar to me but we might just as well talk about the camera or other recording device.

"There is a gap between what we might call the 'manifest' and 'scientific' images of time. Physics sees time as like space. Yet experience regards them very differently: we behave as if the future is unreal, the present special, and time fundamentally directed. These features affect the way we live our lives; for instance, we dread future pain but feel relief when pain is past. Hence there is a significant gap between time as represented by experience and by physics. Closing this gap is the goal of my research. My work shows that time in physics is surprisingly different than space, even when united into spacetime -- despite conventional wisdom. In a very precise sense, physics is able to tell better narratives (make better predictions and explanations) in the timelike direction than spacelike directions. Our macroscopic environments then latch onto this difference to make a representation of time as different than space most natural. By looking at an interdisciplinary mix of fields, including cognitive science, evolution, and philosophy of time, I explain why we believe that there is a common now and also why we care more about the future than past."

1 My point about opinion is that as reality exists independently of us, then only one description of that is correct, scientifically. Our reality referred to the existent reality we inhabit, ie that which is potentially experienceable by all organisms. This equates to your Object Reality. Time is not ‘formed’ by the observer observing. It has to be logically inferred, but that is a reflection of the fact that it is a dimension. It is an intrinsic feature of reality, we do not in any way create it. The perception of the timing and duration of events is another matter.
2 There is a passage of time in reality. Entities change. We can deploy a measuring system to quantify it and enable comparisons of disparate types of change. Relativity is based on the hypothesis that all matter alters in dimension with movement, ie once there is relative movement this effect has to be accounted for. This is not only true of itself, but that then has an impact on the speed of light, which is in addition susceptible to influence depending upon the medium it is travelling in irrespective of relative motion. In a sentence, a whole other layer of complex interference to understand when trying to discern the existent reality which instigated a representation which ultimately resulted in a perception.
3 Your point about the fisherman and plumbing proves the point I was making. Ultimately anything must have a connectivity with something else, because, like the balls in the box, everything is within a confine ie existence). But this is a pointless abstraction, because it has lost all sense of context. In terms of going fishing, the man does not need to know about plumbing. In terms of being contactable, whether he has gone fishing, down the pub, or whatever, is an entirely different matter. It’s a matter of appropriate closed systems and reference points.
4 I am aware that your label is Image Reality. Ultimately the labels do not matter, so long as they relate to some existent aspect of reality. However, as said previously, personally I prefer reality, since there is only one of those. And perception, because there are trillions of these, ranging from the accurate to the stupid. So whilst they may be considered reality to the individual, I feel that is somewhat stretching the intrinsic meaning of the word. Also, image relates to only one of many senses upon which a perception may be based.
5 I am differentiating the various levels. You are including the existent sensory representations of reality in reality (your word Object Reality). This is incorrect. The sensory representations of reality are precisely that, representations. They are not reality. We do not see, hear, feel, etc, reality. We sense a representation based on the properties of the medium conveying the information to us. It may be selective, etc. We have no influence over its existence, so as I previously said, one could attribute this with a reality tag. But they have to be considered to be a different existent phenomena from the reality which instigated its existence. Now, in practical terms, this may not matter for a lot of science. But sometimes it will. And we must be aware of this differentiation (which is then further interfered with in a process of experience) to be able to make the proper choice as to whether to ignore it or not.
6 I have stated what relativity is concerned with above, and that is what those references referred to. But this is not what you are saying.

Technology is irrelevant in the logic of what is being said. So long as we are aware of any potential effects it can have in the process of experience, we can then discount them, in the sense that they in anyway interfere with a representation of reality.

"Project summary
It is common to be in a state of bewilderment after reading a popular account of quantum theory. After all, physicists and philosophers are still trying to make sense out of the numerous puzzles and paradoxes of the theory, such as Schrodinger's cat, the impossibility of determining unambiguously the polarization state of a photon by measuring it, or the mysterious faster-than-light connection between distant particles. It is rarely stressed, though, that these weird quantum effects are deeply connected to issues about the nature of time. If Schrodinger's cat must end up alive or dead, it is hard to maintain a time-reversible picture of quantum evolution. A measurement apparatus able to determine the polarization state of an arbitrary photon would contradict the second law of thermodynamics. The spooky action-at-a-distance between quantum particles can be accounted for if the future can influence the past. What does quantum theory tell us about time? Can facts about time help us interpret the mathematical formalism of quantum theory or understand why Nature chose this theory? We will address these questions in the context of a very new area of research, wherein probabilistic models more general than quantum theory are developed.. "
NB The phrase above - "It is rarely stressed, though, that these weird quantum effects are deeply connected to issues about the nature of time. If Schrodinger's cat must end up alive or dead, it is hard to maintain a time-reversible picture of quantum evolution."
It won't be time reversible because the time reversible bit of the model relates to observer produced reality and not the foundational unobserved reality where passage of time, through continual reiteration of the object universe is occurring. That is along an imaginary historical time line not the hypothetically time reversible time dimension of space-time.
All of these research projects relate to the ideas we have been discussing here.

No, there isn't a "present moment." There is what is present, ie. physically manifest. Much of it is light and other forms of radiation, moving around far faster than we can mentally process. In order to function, we have to create a series of mental images from this constant energetic environment, called thoughts. So it is natural to think in terms of "moments," ie frames of perception. Think of it in terms of taking pictures. Much like a movie camera, we stitch together multiple images, rather then trying to process the information wholistically, because trying to understand all the input without this process of breaking it into coherent units would be like trying to take a picture with the shutter left open. It would just be a blur of indistinguishable input. Yet those pictures, what we consider as "moments" are not dimensionless points in time, because that would be like taking a picture with the shutter speed set at zero. There would be nothing recorded. Yet within any picture, light comes from different sources. If we take a picture of stars, some of the light might be coming from the planets and be a few minutes since it was reflected off the surface, while that from other galaxies would have been traveling for many millions of years. The duration of that travel is a measure of the physical process of light traversing space. Yes, there are innumerable units we can use to measure duration against, but they are all relative to physical conditions, not some underlaying dimension of time. There is no foundational dimension of time. It is real, but emerges from motion in space.
Time is a measure of change, not that change is a measure of time. That is why it is future events becoming past events, rather than the present "moment" as a point moving along the time dimension.

Your post 15/9 13.37, reproduced below to bring it back into the right thread:
1." My" object reality is not experience- able at all. But is the source of the data from which an experience can be produced. Different observers can receive data from the same sources and produce different experiences of it. There are lots of different types of time and when the term time is used, without clarification of which type, it gets confusing. We are talking about 3 different kinds. Time the dimension, passage of time due to changes to the arrangement of the universe and time as experienced by a human being.
I have been in a car crash and time definitely and dramatically slows. That may be anecdotal but many other people have reported similar experience. What is happening in that space, the sensory data input, when processed by the brain produces the output effect of time slowing. Same day, approx. same time 6feet to the left, time would be experienced to be running normally. With respect I do not think it is an entirely different matter because the difference between output reality and source of input is very important.
2 OK I agree, a number of different things are going on. Changes in the arrangement of the universe, inc. changes to objects; and effects upon sensory data within the environment and the role of observer reference frame upon the data intercepted.
3 I didn't think the fisherman was a pointless abstraction but amusing. With respect I still don't think you have understood the significance of the point I was trying to make. Its about there being an open future coming into being everywhere at once, not some parts of the universe being at one time others at another and other bits somewhere else in time. Everything progresses along its universal trajectory together. The whole universe is as one. Its not about where the man has his lunch but that wherever he does he will still be a part of the uni-temporal universe on the way home.
4 You said "I am aware that your label is Image Reality. Ultimately the labels do not matter, so long as they relate to some existent aspect of reality. However, as said previously, personally I prefer reality, since there is only one of those. "
Then it gets ambiguous and difficult to converse meaningfully. I have tried using the term subjective reality but it was unacceptable because corroborated subjective reality is considered objective in science. I have tried saying perception, though with the intended meaning of the image of reality observed, and it is met with the response- perception is irrelevant to physics go and discuss consciousness. I need to use a term that expresses the intended meaning. Until now no one has had a problem with Image reality.
I am aware that image refers to optical phenomena however we are primarily visual creatures and space-time and relativity deals with EM. Other senses could be included in the discussions and the specific term used but it is not necessary to discuss or refer to all of the senses every time IMO. I could I suppose just call it output reality.I do sometimes use several different terms for the same thing to ensure that I have got across what I am talking about.
5 This is just ridiculous because we are agreeing that the representation is not the same as the source of the representation. But now you are saying that my image reality is my object reality. No. You have misunderstood how I am differentiating them. You are also contradicting yourself, You are calling the representations existent and then saying they are not reality.
There is only one reality you have said so yourself. I am calling it the Entirety of reality.There is nowhere else for anything to exist other than within that Entirety. The human being and his brain is within it, the brain wave activity is within it, and the space-time experience of the observer (generated by it IMO) is within it. So is the unobserved source of all sensory input, the objects, substance and media and the sensory data and its medium of transmission which are the object reality.
6 You said "I have stated what relativity is concerned with above, and that is what those references referred to. But this is not what you are saying."
I may not be talking about what is within those specific references.I am trying to explain what I am doing -because it works- not what other people did which may or may not work. Like you I do also have a life outside of this web site, believe it or not. It looked like a lot of homework to find all of them, read them, think about them and comment on them one by one. So I'll pass on that instruction for now.
My response to the above post:
1(a) If your Object Reality is not experienceable, then how does anybody know about it? But I have re-read your definitions, and maybe this is something else, so a) what precisely is it, b) if it is not reality, then what is it?
1(b) There are not different types of time. As I keep on saying, time is a real dimension of an existent reality. Just like reality itself, its existence is not amenable to alteration. Perception of time can be subject to physiological/phychological ‘quirks’, but that is perception, not reality. The timing of perception will be different because there is a time delay between existence and receipt/processing of information (leaving aside relativity, ie matter dimension alteration). There is also the possibility of a ‘doppler’ effect. Think on the following:
Light is the information medium in an experience based on sight. As light travels, there is a delay between the existence of a state and its perception. That delay will vary as a function of the individual spaces involved, and the speed with which the light travelled in each experience. Whilst the perceived order of sequence will never vary, assuming that light has a reasonable degree of constancy of movement (ie is not fundamentally erratic).
The perceived rate of change of a sequence will remain the same, so long as the on-going relative spatial position remains constant amongst everything involved. Because, while the value of the delay is different depending on each individual space, it remains constant. However, when relative individual space is altering, then the perceived rate of change alters, because the delay is ever increasing (or decreasing) at a rate which depends on the rate at which individual spaces are altering. It is a perceptual illusion. The intrinsic rate of change in reality in the sequence being experienced does not
