We can do clever tricks and bend light to make an invisible box- but time travel would be super complicated. The tardis moves through space and time iin crazy directions. Some super clever physicists wrote a paper called ‘Traversable Achronal Retrograde Domains In Spacetime’ (TARDIS) where they explain that we need to know an awful lot of difficult geometry to be able to move in all dimensions through our universe. It’s worth reading this: http://arxiv.org/abs/1310.7983. What you’ll need to know first, is that there is a new quantity in physics called ‘spacetime’., where we combine space and time. Then, the scientists describe how they would mvoe around in this new dimension.
I don’t think we’ll be able to do it properly- I think it would be super hard to come back to where we left from!
I thought that TARDIS stood for Time and Relative Dimensions in Space. This is what Dr. Who’s granddaughter explains in the first episode back in the 1960s. I think that this would very difficult to do, but if they can travel in time relative dimension should be easy.

Thanks guys 🙂 P.S Do you like Doctor Who?
