What is Theory of relativity?
The '''theory of relativity''' is a [[Scientific theory|theory]] [[Albert Einstein]] created in the early [[1900s]]. There are two theories of relativity. The first is [[special relativity]] and the second is [[general relativity]]. The theory tries to solve problems which could not be solved by [[Classical physics]], or by 19th century physics. Some things, like the [[orbit]] of [[Mercury (planet)|Mercury]] or the way light from distant sources bends as it passes a star, cannot be explained by the physics of 1900. Einstein tried to change the basic ideas of physics. He came up with two theories to do that. The first was called [[Special relativity]] and the second was called [[General relativity]]. == References == * Hawking, Stephen. ''The Universe in a nutshell''.
