Which physicist is credited with developing the revolutionary Theory of General Relativity and the famous equation $E=mc^2$, which describes the relationship between mass and energy?

💡 Explanation:

Albert Einstein developed the Theory of Special Relativity (1905), which includes the derivation of $E=mc^2$ (mass-energy equivalence), and the Theory of General Relativity (1915), which redefined gravity as a curvature of space-time.
