  I don’t think so….but then I don’t know a lot about physics etc. and the sorts of things you would need to make time travel work so maybe! It was in the film “back to the future” so who knows! maybe in a few hundred years time everyone will be doing it!

  I’m not sure. I think if we did start to time travel we will see things about our future that we don’t want to see. Its better not knowing what is going to happen it make life more exciting

  No, I don’t think its a good idea either. It’s best to live in the present not dwell on the past or focus too much on the future, be in the here and now.

  Potentially, but the technology required is crazy.
  
  Einstein’s theory of relativity implied that time travel should be possible, as it shows that we can think of time as just another dimension, which we can go forwards, backwards or sideways in. Quantum physics then helped us solve the paradoxes involved (what if you stopped your Mother from being born?) by introducing an infinite number of Universes made up of all possible futures – so you can swap to a new future, without changing the one that you’ve come from.
  
  Unfortunately the technology required is jaw-dropping – you need to accelerate a black hole to nearly the speed of light. But then again, once upon a time airplanes seemed a ridiculous ambition too.

  No! I really struggle with the forth dimension! But I watched Doctor Who last night and he did it so it must be true!
