gfad, if the speed of light is just a number, then mass and energy are just numbers that may vary according to conditions. Is there a machine that records the energy of the Universe and can constantly verify e=mc^2? What is this machine's design and element/isotope arrangement? Is it possible that another equation can describe energy better than e=mc^2?

Rasobasi420, e=mc^2 is a mathematical fact under what assumptions? Did mass come before temperature or did temperature come before mass?

As to your comment that physisists "use words" as opposed to mathematicians, physics is a science that can only exist in conjunction with mathematics. Seriously.
It's a "precise science" in the sense that results are numerical.

E=MC2 may be a simple equation, but the proof behind it is very long and very complicated.
