If nothing happens, well then there's nothing to look for. It could be that once you get pass the speed of light, time start going backwards? You'll need to be at a speed faster than time itself. Just build one on earth, like hyperloop -1 Link to comment Share on other sites More sharing options...

You can't get there from here. There is no physics that allows this, or describes it. You might as well be talking about what happens when you build a perpetual motion machine. You can look at what is true for speeds v > c, and you either have to have imaginary mass or energy. Whatever that means — in much of physics, it is assumed that imaginary terms are not physical.
