Discord in the Quantum World
An alternative quantum resource to entanglement could help physicists in the quest to construct a quantum computer.
A View From the Top
Thinking of causation as a "two-way street"—along which the passage of information can be inverted—could have implications for the origin of life.
Classic Article: Black Holes, Paradox Regained
In 2004, Stephen Hawking famously conceded that black holes do not devour all information when they swallow matter—seemingly resolving the "black hole information paradox" that had perplexed physicists for decades. But some argue that the paradox remains open, and we must abandon our simple picture of spacetime to unravel it.
Quantum Biology: Making Waves in the Natural World
Could quantum effects explain the mechanisms behind smell, photosynthesis and bird navigation?
The Accidental Universe
Have we been fooled into seeing one form of reality, with particular fundamental forces and laws, based on the peculiar way that we have chosen to measure time?

The problem I have with virtual reality/computer simulation hypotheses is that, to me, they inevitably lead, almost paradoxically, to an infinite regress of simulator/programmer. By this I mean that, if we say it is possible for a sufficiently powerful computer/virtual reality machine to run *our* simulated reality so that there is no way we could falsify it, then how could the "simulators" falsify their own "reality" being a higher level simulation? And so on up the heirarchy? It's a bit like,...

The subjective reality that we all inhabit is created by each individuals brain from the input it has received and processed. Everything that is seen is generated internally by the organism and sent to the conscious mind, with the information that it exists externally.
Since the reality we inhabit is already a biologically generated simulation,if the input is good enough the virtual reality is experienced as real and therefore is real.
The reality could be said to be an...

The article comments on our not being able to prove we are not in a simulation, but don’t really talk about looking evidence that we might be.
There is a comments about drifts of fundamental constants - but really, so what.
But it never really ask the question,
“If we were simulating a universe, and machine resource was an issue, then what sort of computational tricks would we use and how might their effect be observable?”
The first thing we did...
