Is gravity still tecnnically a theory?

Question

Since gravity cannot be artificially produced in a lab, does that make gravity still a theory? Just for the record, I know nothing of science.

Answer 1

Eddie -

Good question. I would say that the effects of gravity are pretty well understood (since about Newton's time), but how it works is still open to a great deal of discussion. Gravity itself is not a theory, but there are many theories (General Relativity, String Theory, Grand Unification Theory, etc) that go into a great deal of detail on the subject. It is perhaps the toughest piece of the puzzle to try and fit in with the other ideas that are out there regarding how the universe works.

Answer 2

Gravity is not a theory. Gravity is the name for the the force of attraction by which terrestrial bodies tend to fall toward the center of the earth. We might not have ever even thought of the idea of gravity but there would still be that attraction therefore Gravity isn't a theory as it has been proven because it was so named from that proof.

Answer 3

They have made vacuums in which there are no forces such as friction and verified that g=9.81m/s^2. I am not sure if it is a law how ever I think it is.
