29. Can Time Travel Happen?
Time is not absolute – it can speed up or slow down depending on gravity and relativity – according to Einstein’s special theory of relativity. But does that mean that we can travel backward or forwards in time? Ah, now that’s a question worth figuring out.
Scientists theorize that time travel can technically be possible in certain conditions that let us travel faster than the speed of light. This means traveling through entities like wormholes that connect two different regions of space-time with a shortcut (that we are yet to detect).
But as of today, we don’t yet have a time travel machine with us. So you may have to wait before popping by to meet the dinosaurs or your future self!
