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 objet is moving in a line. Some of its statements are: objects moving at higher speeds experience slower time. Also, the speed of light, or 
, 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 
. 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.
