Understanding gravity may require temporarily forgetting what physicists think they know about gravity.
I've mentioned in other threads the potential problem the human brain can cause in understanding physical reality, but I'll repeat it here. As we learn we store information in brain cells and "program" them to process future information in certain ways. This process can predispose us to continue thinking about physical reality in the same way even though what we have been told are facts are not actually true.
When confronted with something new, the tendency is to explain it in terms we are familiar with. For example, before the term "automobile" became common people referred to such vehicles as "horseless carriages" because that is what the vehicles most resembled.
For example, early science classes teach us that gravity is a force with this concept being reinforced through graduate school. Perhaps gravity is something unique rather than fitting in the category of forces. It might have similarities with forces or light, but be something entirely different.
I am not advocating any of the following concepts, but mention them as concepts that could be considered. The concepts are provided to encourage looking at gravity in a different perspective from the way we have traditionally viewed it. Even if these concepts don't explain gravity they may lead to an explanation in the same way that guessing at the answer of a very complex equation may lead to solving the equation.
Gravity may be a dimension of reality, in particular it might be a property of matter. Matter would occupy a certain area and possess a gravity. Large bodies like stars would not emit gravity, but carry it with them with its effect extending out as if it were "strings".
Einstein suggested that gravity warped space. Perhaps it is matter that warps space, the greater the amount of matter the greater the warping. The sun and planets appear to attract each other because this warping of space has the effect of moving them closer to each other.
As far as we can determine nothing is motionless in space. Earth is moving around the sun, the solar system is moving around the galaxy and the galaxy is moving through space. All objects on earth are moving at essentially the same velocity as earth. In order to move away from earth, even if there were no such thing as gravity, an object would have to expend sufficient energy to significantly change its velocity. Auto racing fans know about what is called "drafting". One vehicle follows closely behind another and is "pulled along" by the leading vehicle.
Gravity may involve two separate processes. One process for a large body in space would be external affecting other matter in space. The other process would be internal. One of the pecular aspects of gravity is that matter is distributed by density with the less dense matter being toward the outside. A basket attached to a balloon sitting on the ground with person inside is too "heavy" to rise, but if the person has a container with helium that can released into the balloon the whole contraption can rise into the air without any change in the total mass of basket, balloon and cargo merely because the mass is spread out over a much large area with the helium in the balloon rather than a smaller container.

Why is it that there is a North pole and a South pole on the Earth? We detect the North magnetic pole using a compass detector, there are four co-ordinate directions on a compass, North,South, East and West, but the detector only detects North. One can know where the North Pole is situated by the signal of the compass needle, at the equator, one cannot locate East or West, they are both just global convience directions, and can be ignored, WRT Earth's magnetic Field.
Now for the Graviton, one has surely to have a detector that can ignore the irrelevent "forces", all except Gravity, one really does need a force filter Graviton Detector?
Now I am certain that Graviton is a spin 2 particle, it's identiy is dual (helicity)?..this attribute I believe is functional to the properties of Gravity, it can be both positive (attraction) and sometimes negative (repulsion).
Spin of 360% equals one rotation in one 2-D direction, (left or right), whereas a 720% rotation can be seen as a "double" spin, or for 2-D field propergations, a full 360% rotation to the left, and a full 360% rotation to the right.
In 2-Dimensions the rotation can be oscillating say from left to right, and continues right to left. In a 3-Dimensional realm, this action results in a Vector rotation . Like the fact one can travel from North to South and continue to North (full rotation on the globe), one can also travel North-South-North, using the "-" that are equvilent to East and West?
A full Gravity detector would be like a compass that detects all directions, not just the North Pole?
A 2-Dimensional wave can have two vector rotations, expanding or contracting, an expansion vector would entail a spin left, and a contracting vector a spin right ( think of a fractal image, or a spinning "vertigo" label), wheras in 3-Dimensions, the Graviton would be an encompassing vector field, which produces no detectable particles or waves?.. One could label it as a perfect Fundemental Vacuum.
Iam certain you cannot detect the perfect fundemental Vacuum, so the Graviton must be undetectable, by its very nature, it a "particle" label, but it has been a "one-off" process in the early instants of the pre-universe bang?..a inflation wave/particle?
Graviton is a single particle that gave rise to inflation, which fluctuated out of the perfect fundemental Vacuum, it may be in the future there will one Anti-Graviton vector field?

If this recent paper is anything near correct (which I think it is)..then there are some really interesting issues that are quite open to discussions?
