Did Einstein really have the answer for what is gravity and does it contain all fields?
- Jeffrey KLv 67 months agoFavorite Answer
Gravity is the curvature of spacetime. Einstein described this mathematically. This is General relativity.
Gravity does not contain all fields of force. It is only one of 4.

It used to be all fields round here

Newton had more and better answers, Einstein just defined the math behind gravity.

Einstein worked on a Unified Field Theory but couldn't hack it. Although some people believe that he used the theory he had to engineer the ill-fated Philadelphia Experiment. Who knows?

What do you mean by "answer"? General relativity showed that gravity is really the result of masses curving space-time. Particles with mass are confined to follow the curvature of space-time. If there is a large mass near by, freely falling particles will follow the curvature to the mass. What we call gravity is the result of the surface of a mass, like the earth stopping us from freely falling to the center. The surface obstructs our fall and we experience a 'pull" downward. In principle, anything acting in space-time has to be contained in space-time. So photons, the carriers of electromagnetic force, travel on the shortest paths through space-time while following the curvature. One of the biggest issues though is the inability to derive a quantum theory of gravity starting with general relativity. So while the electromagnetic, weak and strong forces all have to operate in space-time, we have yet to develop a self consistent, finite model that yields testable results incorporating all the fundamental forces.
