Seriously, Einstein's equations on special relativity does not allow "time travel". What happens is that because the speed of light is constant in all reference frames, so if someone is traveling at close to the speed of light, time slows down for him/her. This means that it is possible for someone to travel on a spaceship and travel to the stars, and then return back to Earth in several years (to him/her), but find that hundreds or thousands of years has passed on Earth and no one he or she knew would still be alive.
Einstein's equations does not allow for time travel to the past, only to the future.

Hi. E=Mc^2 is formula. The "E" stands for energy as measured in certain units. The "M" stands for mass in certain units. The "c" stands for the speed of light and the "^2" means you raise "c" to the power of 2 (you square it - multiply it by its self). The "=", as always, means that everything on the right side of the equation matches exactly that on the left. What the formula MEANS is that any amount of mass contains a very large amount of energy. It also means that to make mass from energy requires a very large amount of energy. The question in my mind is why c is squared, not times 3, say or some constant. There is a beauty in most of the really meaningful formulas describing the way nature works.

Could be he cancelled himself out with the rigidity of his own equation! I'm sure there are countless physists who have tried, the answer depends on something yet to be discovered - an unknown force effecting the speed of light and that doesn't figure into his equation, or into the laws of motion. Outside the boundries I believe it is possible, just hasn't been proven how -yet.

They HAVE been solved. Not only solved mathematically, but proven to be true and accurate by countless experiments.
So far everyone else has given you the wrong formula. See this website for the correct equation, along with how to solve it ==>

I have and succesfully to however i must hid my finding from the scientific world or else the government will develope time travel and continue to control our lives.

E=MC2? Energy=Mass' Circumfrance squared. I'm not very good with math.....

t(v)=t(0)((1-((v/c)^0.5))^0.5)
