The equivalence of mass and energy. They are two sides of the same coin, it’s just a question of converting units.
Explanation:
Higher up in physics, we actually measure particle mass using a unit of energy (called electronvolts, eV.)
The implications are vast - each kilogramme of mass ‘contains’ more energy than you could imagine, roughly a million billion Joules. This means that you could run your house for a year off the mass of a speck of dust you can hardly see (if the energy conversions were efficient.)
The term, c in the equation is the speed of light in a vacuum (
