E = mc² is Albert Einstein’s famous mass-energy equivalence equation from his theory of special relativity. It states that energy (E) and mass (m) are two forms of the same thing, and that even a tiny amount of mass contains a massive amount of energy, calculated by multiplying the mass by the speed of light squared (c²).Here is a quick breakdown of what the equation tells us:E (Energy): The total intrinsic energy of an object at rest.m (Mass): The amount of physical matter in an object.c² (Speed of Light Squared): Because the speed of light (c) is incredibly fast, squaring it results in a huge number. This acts as the conversion factor, meaning a very small amount of mass holds a staggering amount of potential energy.Why is it important?The equation explains why phenomena like nuclear fission and fusion are so incredibly powerful. For example, in nuclear reactions or the sun, a tiny amount of mass is lost (converted) and released as an enormous amount of energy.
