This is a shortened equation. The correct equation is $$E^2=(mc^2)^2+pc^2$$ where $$p$$ represents momentum. As for why, it is all the mass converted into energy along with the momentum. · 3 years, 8 months ago

It is trying to prove that mass can be converted into energy. Since c^2 is constant, a few mass of a radioactive molecule can produce a large number of Energy · 4 years, 1 month ago

it is a result of unifying calssical mechanics with new scientific developments of 19th century by the brilliant mind of einstein · 4 years, 1 month ago

It's on my list for one of the thinking like a theorist posts, so we'll get to a big discussion relating to E=mc^2 in a few weeks. Hang on! Staff · 4 years, 1 month ago
