Ok dudes heres how it is, relitivity is a very complex equation, and DOES NOT apply to everything. its just like newtons' laws, because newtons' second law does not apply to smaller accelerations then 1 x 10 (to the -10) relitivity has to do with pure energy and gravity, I too, am only 17, but love this stuff. you people talk like his theory is proven. It has applications, however, not all of the theory i belive works. anywayz, but you need to have a lot of math knowledge to understand this. (no offense in anyway ment) however, most basic phyisics books have pretty good basic examples and descriptions of realitivity. -l8r email if u want to know more
