Energy-Mass Equivalence

Energy-mass equivalence is the idea that energy and mass are two forms of the same thing, expressed by Einstein's famous equation, E=mc². This means that a small amount of mass can be converted into a large amount of energy, and vice versa. For example, in nuclear reactions, tiny changes in mass produce enormous amounts of energy. Essentially, mass can be seen as condensed energy, and energy has mass. This relationship helps us understand phenomena from the sun's energy to atomic nuclei, demonstrating that mass and energy are interchangeable aspects of the universe's fundamental fabric.
