Relativity

Relativity is a theory of physics that describes the relationship between space and time. It was first proposed by Albert Einstein in 1905 and later expanded upon in 1915. The theory of relativity has two parts: special relativity and general relativity. Special relativity deals with the laws of physics in inertial frames of reference, while general relativity deals with the laws of physics in non-inertial frames of reference, such as those in the presence of gravity. The theory of relativity has had a significant impact on space and astronautical engineering, as it has led to the development of technologies such as GPS and has helped us understand the behavior of objects in space, such as black holes.
