Question

what is relativity? elaborate the concepts of special and general relativity.

Answer 1

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to elementary particles and their interactions, describing all their physical phenomena except gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy.

Answer 2

Relativity is a theorem, formulated by Albert Einstein, which states that space and time are relative and all the motion must be relative to frame of reference. It is a notion that states, laws of physics are same everywhere. This theory is simple but hard to understand.

It states:

There is no absolute reference frame. One can measure velocity if object or momentum is only in relation to other object.The speed of light is constant irrespective of who measures it or how fast the person measuring it, is moving.

Albert Einstein’s Theory of Relativity encompass two theories namely Special Relativity Theory and General Relativity Theory.
