Where Does E = mc² Really Come From? | The Hidden Origins of Mass-Energy Equivalence
E = mc², the famous relation expressing mass-energy equivalence, is often touted to be a consequence of Einstein's Theory of Special Relativity. Yet, E = mc² was actually discovered a full five years before Einstein's theory even made its debut. Where does this equation really come from then, and what is it truthfully telling us? Join us as we dive deep into the real history and origins of physic's most talked-about equation.
