Has any body ever heard or read about the universal expansion of atoms as the final theory of gravity?

Question

What do you think of its validity?

Answer 1

There are some people who try and explain gravity with this hypothesis. It really isn't a theory since it isn't based on facts or observable patterns. The main problem with expansion theory is it doesn't explain anything. It tries to replace Newtonian physics with the expansion of atoms. Motion is supposed to be naturally curved (nothing causes this curvature mind you) and the expansion of two passing objects is supposed to explain orbits. The biggest place that this fails is in the fact that no achievable orbit is possible through expansion theory. The other problem is in order to curve an objects motion you have to affect it with some outside force...gravity. There are no straight trajectories observed in the universe because gravity is ubiquitous. (Something expansion hypothesizers tend to over look.) The reasoning behind natural curvature is that there is no observed straight trajectory in the universe. The only problem with this logic is that gravity is the cause of the curvature and without it anything in the universe would travel in a straight line. One other thing to point out is it doesn't explain uniform acceleration. Many of the believers in this hypothesis believe that the inverse square law doesn't exist. Clearly it does, objects accelerate. To summarize this, expansion theory (hypothesis really) is completely bunk. Hope this helps. Yours truly,

Another flaw in this illogic is to noted that if every atom was expanding then they would soon collide regardless of speed and direction of travel unless space time was also expanding with them. If THIS happened AND there was no gravity then things would travel on in a straight line.

Answer 2

Its an idea conceived, at least in part, by "Dilbert" cartoonist Scott Adams.

He's not a trained astrophysicist. He's not even an engineer like the characters he draws. I love his sense of humor, but he's not even a particularly talented artist.

The idea that gravity is an illusion caused by every atom in the universe simultaneously doubling in size is ridiculous on its face.

Remember that Occam's razor requires us to look for the "simplest" solution that fits the evidence. I can see nothing simple about atoms spontaneously doubling in size instantaneously and all at the exact same rate. I can think of no reason why this would cause an illusion of gravity, either, since if MY atoms are expanding as well, then I should notice no effect.
