No, Einsteins theory was about travelling in time actually. If you travel in space you'll be a little "younger" than the rest, I suppose that's what you meant. I can't remember how the theory was built up, all I remember is that it was complex
It's about bending time in the dimensions if I remember correctly. The thing is that scientists as of lately are starting to believe in this theory. Einstein was pretty amazing. It's like with him as with Darwin, at first people didn't believe in their theories, but a hundred years later(for Darwin) it's being proven(I refer to Darwin here obviously, since he had some parts written in "The origin of species" that were proved like a couple of years ago. The scientists were very sceptic, but had to change their minds).
Darwin is the greatest hero I know of. Denying his theory is ridiculous. We have lived more than 6000 years people, stop denying.
