Einstein’s Theory of General relativity
Albert Einstein determined the law of physics that the speed of light if independent on the motion of all observers and that i there is a special relativity to it. The law of physics interpreted that the speed of light within a vacuum will be the same no matter the speed at which the observer travels. Einstein space-time is a continuum. Events that occur at the same time could occur at different places. Could this mean that parallel universes exist?
Through the equations and the working process he found out that massive objects caused a distortion in space-time.
