Albert Einstein’s theory of relativity is actually two separate theories: The Special Theory of Relativity postulated in 1905 paper and The General Theory of Relativity postulated in 1916.
In this theory Einstein sought to explain situations in which Newtonian physics might fail to deal successfully and in doing so he proposed revolutionary changes in human concepts of time, space and gravity
The Special Theory was based on two main postulates:
- Speed of light is constant for all observers.
- The laws of physics are same for all observers in all inertial frames.
The essence of Einstein’s paper was that both space and time are relative which was holding true in a special case, the absence of gravity. Relativity was a stunning concept and scientists all over the world debated on Einstein’s famous equation E = mc2 , which implied that matter and energy where equivalent, more specifically that a single particle of matter could be converted into huge amount energy.
But the most astonishing thing about relativity is that no object can travel faster than speed of light or even at speed of light. Therefore in order to protect the cosmic limit your relative mass increases as your speed increases, in short “The faster you move, the heavier you get!”
The theory of relativity is a path breaking concept which has opened up many new fields in science and for the benefit of humanity.
