Contrary to Einstein's theory there is no physical barrier regarding the speed of light and speed does not compress an object into an infinite line which later travels backwards.


So I guess all those experiments on time dilation they have verified with atomic clocks are bunk?

No, we can't travel faster than the speed of light in a linear fashion for a multitude of reasons. If we could, then we already would have, since all we need is a decent power plant, right? Likewise, in all our astronomical observations, why have we yet to observe a particle that does. You'd think a supernova might be able to push matter faster, but even /they/ are limited by the upper bound of the speed of light when they explode.


Also, one minor nitpick: you can't travel backwards in time. Can't be done, not in a traditional sci-fi sense. The accelerating expansion of the Universe prevents this.


But what we /might/ be able to do is fold space and travel through it, or exit space and re-enter it... though I'd argue the former may be easier than the latter.
