I am sure that a lot of people who have been watching Doctor Who over this 49 years have asked themselves (or others) about the science of Doctor Who. What if time travel is possible? What if a Tardis could exist? How it would look like? How it would behave? What would need the sonic screwdriver to function?
And so on, and so on… There are a lot of things that appear in Doctor Who that are wonderful… and made people to ask questions. The following show is an episode of GTSpecials… it tries to respond to these questions.
Enjoy. 🙂 I hope it make you curious enough to ask more questions. 😀
