the real reason they don't say einstein- e=mc2
but say einstein- relativity
because einstein basicly won ww2 singlehandedly by inventing the atomic bomb with his e=mc2 but all the ww2 boys want to try to claim the victory but we all know how ww2 was won
so they always try to draw attention away from e=mc2 by saying einstein- relativity like that is what is really important . like how often do you move at a 100,000,000,000 mph so that time could slow down.
