Theory of Relativity

The Theory of relativity , revolves around two theories coined by Albert Einstein. They are:-


Special relativity is a theory of the structure of spacetime. In his special theory of relativity Einstein showed that time and length are not as absolute as everyday experience would suggest.

  • Time dilation : This theory states that time will pass slower for someone traveling near the speed of light relative to someone standing still. Moving clocks tick slowly as compared to observer’s “stationary” clock.
  • Length contraction : Objects are measured to be shortened in the direction that they are moving with respect to the observer.


In Einstein’s theory of general relativity he proposes that time will run more slowly the stronger the gravity. This means that time will pass faster on top of a mountain than at the beach. However its a very small difference to get noticed. Theoretically, if you could travel faster than the speed of light, time would go in reverse.
