e=mc^2 is not the theory of relativity. wtf. it's just mass-energy equivalence. it happens to have a factor of c^2 which is relativistic, but there is no equation for relativity in general. and general relativity's is G_uv = 8piT_uv, etc.
re: author
To anyone reading author reply and wondering wtf they are talking about. They just typed some random expressions. Author is as ridiculously stupid as I thought. I've lowered my rating from 3 stars to .5 stars.
