Is time travel scientifically possible?
Time slows down measurably the faster you travel. Some scientists believe certain sub-atomic particles may travel back in time.
But if time travel became possible for humans it could create deep paradoxes, like meeting your younger or older self.
Should we ban research into it before it鈥檚 too late?
Did you know?
According to Einstein鈥檚 theory of relativity, the faster anything travels, the slower time passes, an effect called time dilation.
