Relativity

Relativity is a branch of modern science that has two parts: special relativity and general relativity. Both were formed by Albert Einstein.

Special Relativity

Special relativity deals with spacetime and its behavior when an object is moving in a line. Some of its statements are: objects moving at higher speeds experience slower time. Also, the speed of light, or $c$, is the highest speed any object can achieve. Objects moving at c would then move to their destination in no time since time slows down to a stop.

Special relativity also deals with the equivalence of mass and energy, with the famous equation $E=mc^2$. This shows that the amount of energy an object contains is equal to its mass multiplied by the squared speed of light. It also shows that a huge amount of energy can come from only a tiny piece of matter.

General relativity

General relativity deals with spacetime and its behavior when an object has any behavior. It deal with things that the Special Theory of Relativity can not deal with
