Answer :
The Einstein Theory of Relativity states that all objects in motion are subject to the same laws of physics and that the speed of light in a vacuum is the same regardless of how fast the light is moving or the people who see it are moving.
Theory of Relativity:
- In the concept of thory of relativity there are two sub-concept theories as follows:
- Special relativity.
- General relativity.
- Importantly this is a major theory compressed by the greatest scientists Albert Einstein.
- This theory comes under the study of Astrophysics. because this concept is based on both Astro + Physics (Space + Physics science).
1) Special relativity:
- This topic is nothing but this relates with the physical Phenomena.
2) General relativity:
- This related to the law of gravity and gravitational forces.
- This concept totally based on physics and space that's astrophysics and cosmology.
