I was asked by Julia Rothman to contribute to her upcoming book, The Art of Science, where illustrators are paired with scientists to help answer questions the common person might have about the way the world works!
I illustrated the question, "What happens to time as it approaches the speed of light?" - and the question itself was answered by my dad! A fun little collaboration. I still don't quite understand the answer...but basically it seems that time will get quicker as you approach the speed of light, but only from the point of view of an observer from Earth. So, time will always seem to pass at the same rate to the traveller, but back on Earth time will be going much more quickly. Or something like that.
