What is the theory of relativity?

Relativity is a physics theory developed by Albert Einstein at the beginning of the 20th century. The theory of relativity can be divided into two parts: special relativity and general relativity. Special relativity deals with the way time and space change relative to the observer, while general relativity extends this to include gravity and the effect of mass on time and space.

The basic idea of ​​relativity is that time and space are not absolute but depend on the observer’s movement and gravitation. This theory has revolutionized our understanding of the universe and led to, for example, the concept of space-time and the study of black holes and time holes.

The theory of relativity has been tested and proven in many different ways and has proven to be a very accurate and reliable theory. It is also the basis for many phenomena and theories of modern physics.
