Should research into time travel be banned?

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’s too late?

Did you know?

  • According to Einstein’s theory of relativity, the faster anything travels, the slower time passes, an effect called time dilation.

  • Clocks on the International Space Station, actually run 0.014 seconds slower each year than the same clocks on earth because of time dilation.

  • Scientists are exploring the idea that some kinds of tiny particles may actually travel backwards in time.
