Scientists simulate time travel....

If this involves a Black Hole, and it appears to, then whatever goes through it is going to come out as subatomic soup, likely in an alternate universe, from which there's no obvious escape. So in other words, the 'Theory of Everything' says in effect that 'nothing is going to turn out exactly like you thought'. And now, we can prove it, hypothetically of course. Isn't science wonderful? 

And why do I need time travel, if I can't afford to go anywhere, and wouldn't have any way of knowing what to expect if I got there? This is what's known as 'theoretical physics' - it's all mind over matter: if you don't mind, it don't matter.
