What is Albert Einstein theory of relativity?
There are 2 theories of relativity, the special theory & the general theory. The Special Theory of Relativity says that all constant motion is relative; you can’t be moving in an absolute sense. There’s no way to show that you’re “really” moving. It also says that the speed of light (c) appears to be the same to everyone, even if they’re moving. From these 2 facts, the theory then shows that as you move faster, a person who is not moving with you, will (1) see your length shrink, (2) see your time slow down, & (3) see your mass increase. That’s pretty amazing. The theory then shows that E=mc2. It also implies that time is the 4th dimension & that space-time is the best way to look at things. The General Theory says that gravity and acceleration are the same thing. For example, in a falling elevator, you feel no gravity, and in a rocket that’s accelerating, it creates gravity that pushes you down. Also, the theory says the best way to understand gravity is to think of it as the bending
