      Honestly, I’d probably go back in time just to make the time machine that allowed me to do that! I’ve always been fascinated with time so I’d probably just go back to give myself the blueprints for the machine 😛

      My work is about learning how the Solar System formed, so if the time machine was also some kind of spaceship it would be very handy to go back and see what really happened and whether our theories are right!

      If you believe the movies, travelling back in time could have disastrous consequences on the present or even paradoxes! It’s for these reasons even the cleverest theoretical Physicists can’t agree whether time travel would even be possible in principle, let alone how to build a time machine. I’ve always loved the time paradoxes in science fiction.

      I think it’d be more cool to visit the future though and see what fantastic things we come up with that no-one could even dream of right now. Future time travel is in principle easy, Einstein told us all you need to do is go really fast (close to the speed of light). The problem is there’s no way of going back though that we know of.

      Amy, would I be allowed to go forward in time to when we find life on other planets? Because that’s where I’d want to be. If I have to go back in time, I’d want to be around when Einstein figured out the theory of relativity. Not only is the theory super-important, but I’d also get to hang out with Einstein, who seems like a pretty cool guy. 🙂

      (I also love Usman’s answer!! HA!)
