What do you think of string theory? Also what's the least number of dimensions that guarantee time travel?

That's an awesome anecdote, thank you for sharing it! What about time travel? What will happen if a body travels exactly with the speed of light and then breaks that barrier? Would it enter in another time dimension? I'm starting from this point of view: for centuries we thought that Newton's laws applied for all velocities, time frames etc., and then came Einstein's theory of relativity which yielded to the fact that the previous Newton's laws were only a special case of Einstein's. What if Einstein's theory, either the special or the general, is just a special case of some broader theory which enables travelling with a speed greater than the speed of light?
