Is Time Travel really possible? In the following clip, part of The science of Doctor Who series, the professor Brian Cox – a confirmed Doctor Who fan – undertakes an experiment with a light showing that time moves faster for a stationary clock than a moving clock, which appears to move more slowly over the same length of time. His conclusion is that time travel is possible, but only into the future!
We only need a TARDIS to show how wrong he is. 🙂
