In honor of the 50th anniversary of Doctor Who showing this weekend I decided to read the book The Science of Doctor Who written by Paul Parsons. This book reminded me of why I use to love science, at least the astronomy part of science. Even though there were many sections that were way over my head, the parts that I did understand and enjoyed the most had a lot of good points.
Parsons took the science behind Doctor Who and gave the explanations to how they could one day be possible if they were not already. He also gave explanations why some things can never come to be. For example; have you ever thought of how that TARDIS could be bigger on the inside than it is on the outside? Would that be possible? To me Parsons comments from a physicist, Van Den Broeck, who is an expert with Einstein’s general theory of relativity also known as GR, made some sort of sense to a degree. (Remember I did not say I understood it all.) Basically if I can explain this right, it would be like having a two-dimensional rubber with a bubble shape much like a balloon attached. The entrance is small, like the part of a balloon that you would blow air into. He used the idea of an ant that would crawl into the entrance, which would be small compared to the inside. When the ant would crawl into the bubble there would be a huge surface area. The next part is where he lost me a little.
Broeck said “ Replace the circumference of the throat by the surface area, and the surface area of the bubble by volume, and what you then get is a large volume with a small surface area.”
Looking at the diagram it made sense. Parsons had many examples like this from explaining how the Cybermen could become reality to alien life on another planet. Oh, but let’s not forget the biggest of them all. Time travel and would it be impossible? Well, to answer this question and more, you will have to read the book. Then let me know what you think Whovians. Enjoy the 50th anniversary this weekend!
