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.

I wish I could make a tardis! But I only think Dr Who would be smart enough for that.
(Though I do have a mini tardis – my friends gave me one when I became a doctor in chemistry! )
If I had a real one I would travel though time and see the dinosaurs and see what they really looked like!
what is your faverout science tv pogram
are you as clever as Sheldon from the big bang theory the TV program?
How on earth can you make a curved tv
do any of you watch the flash on sky 1
do you watch big bang thyeroy
Do you think the roll up TV will be like the camera? Do you think it will start off everybody liking it, then it gets
Are you eco-friendly when it comes to computers and tv's ect?
I tried the ‘who can open there eyes the longest challenge’ today at school, my eyes started to ache. Why is this?
Are you sad about the end of the i’m a scientist? (4 Comments)
did you ever run away from home
