Question: do you know what E=MC2 means?

This equation was formulated by Albert Einstein (one of my favourite scientists) and shows the correlation between mass and energy. It basically says that every mass has an energy equivalent and vice versa. Where E is the energy, m is the mass of the system and c is the speed of light in a vacuum (3×10^8) m/s). I hope this isn’t someones physics homework!
