He's right on that. E=mc^2 is about as proven as these things get.
It was proven many times in many different ways. The atom bomb was pretty good proof. Also Marie Curie, who showed that radioactive materials lose mass when they give off radiation, exactly with an E=mc^2 relationship. It was also shown in molecules of water - a molecule of H2O weighs less than two particles of H and one particle of O, by exactly the binding energy (again demonstrating E=mc^2).
E=mc^2
could be wrong if the fundamental tenants of special relativity are wrong. For E=mc^2 (and the longer related equations) to hold, we have to assume that the speed of light is constant in any frame of acceleration, and we have to assume that the laws of physics don't change in an unaccelerating frame. There are some serious scientists who doubt relativity, but the overwhelming majority think it's correct.
So while E=mc^2 is about as "proven" as any other 20th century physics (like global warming), it's not as "proven", say, as the idea of a Judeo-Christian God handing out judgement in the afterlife. That is to say, realitivity is
not in the bible.
