I know little to nothing about G.R. but it is interesting to look up knowledge,especially physics, so please correct me if I am wrong..(adsbygoogle = window.adsbygoogle || []).push({});

It is easy to picture how one giant mass distorts spacetime on 2D scale, but what if there is multiple bodies of masses present and would this turn into a complete mess?

Also GR proposes that gravity is no longer a force, rather it is merely a distortion of space time. It is easy to see that any thing in motion will circulate around a massive body because of the curved geodesic path, but what about something that is at rest? Gravity still has to accelerate it, so according to Einstein, how does curved space manage to do that?

When does general relativity come in handy? The field equations are a set of ten nonlinear diff.equations, that is a huge pain in the *** to solve without computers. Einstein didNT have computers, so what was his original intention of coming up with GR*.? I heard it was something about Mercury's orbit.

Thanks
