I once read about a possible way to 'cheat' the system. It works on the assumption of multiple dimensions, not just the three we know about. As Einstein himself once said. You can have a limit of one, but if something can have more than one state, then it can have many.
If space is curved, as a lot of scientists think, then instead of walking round the curve to get from one place to another, if you can find the right different dimensions, and can find a way to use them, your wanted destination might just be one step and a twist away.
Yes a lot of 'ifs' there
