how is e=mc^2 a consequence of special relativity?

Answer 1

The equation E=mc^2 is a consequence of Einstein's theory of special relativity, which revolutionized our understanding of the relationship between energy and mass. In special relativity, Einstein proposed that the laws of physics are the same for all observers, regardless of their relative motion. This led to the famous equation E=mc^2, which states that energy (E) is equal to mass (m) times the speed of light (c) squared.

This equation shows that mass and energy are interchangeable, and that even a small amount of mass can be converted into a large amount of energy. This concept has had profound implications for our understanding of the universe, leading to developments such as nuclear energy and atomic weapons.

In essence, E=mc^2 is a consequence of special relativity because it is a direct result of Einstein's fundamental principle that the laws of physics are the same for all observers, regardless of their relative motion.
