Question

explain theory of relativity

Answer 1

the theory of relativity is to prove that energy and mass are almost the same

Answer 2

In Einstein’s view, there is no absolute space and all motions are relative. The time, mass, length and space are interdependent and are not absolute. Einstein, in 1905, profounded the special theory of relativity. The special theory of relativity deals with objects and systems, which are either moving at a constant speed with respect to one another or at rest.

Albert Einstein published his special theory of relativity and the theory of photo electric effect in the same year 1905. It was a very productive year for him and for Physics.
