Is Gravity Just Entropy Rising? Long-Shot Idea Gets Another Look.
"the idea that gravity is a collective effect — not a fundamental force, but the outcome of swarm behavior on a finer scale — still compels physicists."
Interesting thought. If this is the case, perhaps there might be cases where all the elements of the collective are not present and gravity might behave differently.
"Earlier this year, a team of theoretical physicists
put forward(opens a new tab) what might be considered a modern version of those 17th-century mechanical models. “There’s some kind of gas or some thermal system out there that we can’t see directly,” said
Daniel Carney(opens a new tab) of Lawrence Berkeley National Laboratory, who led the effort. “But it’s randomly interacting with masses in some way, such that on average you see all the normal gravity things that you know about: The Earth orbits the sun, and so forth.” "
Getting awfully close to an aether. The Michelson-Morley experiment supposedly disproved aether. Maybe there is an aether, but it doesn't interact with light. It doesn't seem likely that there is an aether-like substance that causes gravity, but doesn't interact with light. But, maybe.
"...Entropic Gravity, pegs that deeper physics as essentially just the physics of heat. It says gravity results from the same random jiggling and mixing up of particles — and the attendant rise of entropy, loosely defined as disorder"
"The new model has the virtue of being experimentally testable — a rarity when it comes to theories about the mysterious underpinnings of the universal attraction."
Gotta love that.
"when physicists used quantum mechanics to study what happens in the distorted space-time around a black hole, they find that black holes give off energy like any hot body. Because heat is the random motion of particles, these thermal effects suggest to many researchers that black holes, and the space-time continuum in general, actually consist of some kind of particles or other microscopic components."
It is difficult to suggest something like space and/or time can warp without a physical presence.
