I hate to break this to you but gravity isn't even an hypothesis much less a "theory".
It's more an observation.
If the earth were flat it really would empty the oceans right over the edge. Well, at least it would unless you defined "flat" such that it is about the same as we mean by "sphere".
Until we know why gravity works or the mechanisms by which it works there really isn't much more we can say than "observation suggests all matter attracts proportionally to its weight and the square of the distance". Putting an observation in arithmetic is not the same thing as theory or one unicorn plus one unicorn would equal two unicorns. It really doesn't matter if the so called theory of gravity exists or not since the planet is still spherical and was even before Newton got hit in the head. It doesn't make believers in science any more right than anyone else.
Believing in gravity and the "theory of gravity" makes them less right, not more.
Sorry, but no, Einstein's gravity follows all of the rules of being a theory. You won't find one rule that it does not follow. Even Newton's "laws" follow those rules. It was merely not as accurate as Einstein's theory.
I know, science denial is all that you ever appear to have. You seem to resent that when it is pointed out that you only have claims and never evidence to support you. When it comes to basic concepts Wikipedia is hard to beat:
"A
scientific theory is an explanation of an aspect of the
natural world and universe that has been
repeatedly tested and corroborated in accordance with the
scientific method, using accepted
protocols of
observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an
experiment.
[1][2] In circumstances not amenable to experimental testing, theories are evaluated through principles of
abductive reasoning. Established scientific theories have withstood rigorous scrutiny and embody scientific
knowledge.
[3]"

How is either Einstein's General Relativity or Newton's Universal law of gravitation not a theory?
