- Einstein's theory of relativity consists of two main theories: special relativity and general relativity.
- Special relativity states that the laws of physics are the same for all observers, regardless of their relative velocity.
- General relativity extends special relativity by including the effects of gravity, which is described as the curvature of spacetime caused by massive
objects.
- General relativity successfully explains the orbit of the planets and other astronomical observations.
- Both special and general relativity have been confirmed by numerous experiments and have become integral parts of modern physics.
- The theory of relativity has far-reaching consequences, such as the equivalence of matter and energy (E=mc^2) and the predicted existence of black
holes.
