Whose equation says energy and mass are interchangeable?
PhysicsRelativity
Quick Answer
Albert Einstein’s mass–energy equivalence, written as E=mc². It shows that a small amount of mass can correspond to a huge amount of energy.
The Full Story
Albert Einstein introduced the mass–energy equivalence in 1905 as part of special relativity. The equation E=mc² means energy equals mass multiplied by the speed of light squared, so even tiny masses represent enormous energy because c is so large. The idea is central to nuclear physics and helps explain energy released in nuclear reactions and stellar processes. It remains one of the most famous equations in science.
