Time travel could soon become a reality claim physicists | Mail Online: "If a time traveller went back in time and stopped their own grandparents from meeting, would they prevent their own birth?



That’s the crux of an infamous theory known as the 'grandfather paradox', which is often said to mean time travel is impossible - but some researchers think otherwise.

A group of scientists have, for the first time, simulated how two time-travelling photons would interact, suggesting that, at a quantum level at least, jumping through time might be possible."
