        I’m not a physicist, but I love Dr Who and I used to think about time travel a lot! Time travel is possible in theory, but we can’t jump into a tardis and go whizzing back and forward through time, sadly. One way of travelling through time would be by a wormhole, which is basically a shortcut through space and time. However, it is not known if these even exist, and if they do, it would probably not be easy or safe to travel through them.

        In principle time travel is possible but know one knows how it would work! If you are interested in this subject then you should do some research into a famous scientist called Stephen Hawking. He has written some interesting books which discuss the topic of time – although you might find them difficult to understand unless you have taken some physics classes. 🙂
