Gravity, what is it?
For way too long, I’ve wondered how bodies of matter separated by empty space can attract each other, ie be accelerated toward each other. I now suspect that gravity is not a separate attractive force but an imbalance of the recently discovered repulsive force called dark energy. Probably dark matter will be explained as self-augmenting inhomogeneity of dark-energy generation, ie instability of dark-energy distribution. In other words, dark energy is the electroneutral force of space, accounting for all gravity manifestations including dark matter. Serious speculation appears to be progressing toward this hypothesis.
I believe that space is filled with a high-resilience medium (aether) which propagates electromagnetic disturbances (light, radio, gamma) and deformation disturbances, as light-speed waves. The deformation waves (possibly compressions) transfer momentum to matter particles, accelerating those particles mostly in the direction of their propagation. These waves may come from particle motions or may be spontaneous or may be from primordial momentum or from particle destruction. In any case, the deformation waves constitute dark energy. Every sample of space has dark-energy waves propagated through it in every direction randomly. Some waves that enter a matter body may not pass through but be absorbed in the act of giving up momentum to (accelerating) the body's mass elements.
I believe that these dark-energy waves are very forceful in accelerating encountered particles but (like neutrinos) very inefficient in finding particles to encounter within a matter body. This feature may become significant in modeling gravity. The gravitational action of dark energy can be conceived as follows (with the earth as an example massive body).
Surrounding the earth (as for any massive body in space), there would be a deficit of dark-energy waves from the earth’s direction, many of the waves from that direction having been absorbed in accelerating particles within the earth. In essence, the earth casts a shadow all around itself, a deficit of waves in the direction away from itself. The earth’s dark-energy shadow would be most intense at the earth’s surface and would decline essentially as 1/r^2 with distance from the earth. Any other body in the earth’s dark-energy shadow would receive waves accelerating its particles toward the earth more than from the earth, that other body being thereby accelerated toward the earth – ie attracted toward the earth. These actions are of course mutual, each body producing a deficit of dark-energy waves away from itself, hence an acceleration towards itself.
This is an ancient idea with specific modern names for the agents. I have eluded to it in earlier blogs:
