Sci-Fi Science

As a professional scientist with a PhD in science and who loves science fiction and fantasy, I thought it would be a great idea to explore the true science behind Sci-Fi and fantasy, to explore what could really be possible and what is most likely never possible. Why have I done this? There are two reasons, the first is because it was science fiction that sparked my interest in science. It was science fiction that, as child, made me wonder if it really was possible to travel to other worlds in space ships, to travel in time and to meet alien lifeforms. Mankind has made such impressive leaps in technology, what could happen in the next 20, 50, 100, 500 or more years?. Then there's fantasy, swords and sorcery, and it's amazing how many people do not understand the difference.

When watching or reading science fiction, there several common themes that repeatedly turn up. For example space travel at faster than light speeds or meeting aliens, either good or bad. These common themes are explored here and assessed whether they could ever been technically possible. For example, it may be beyond our technological capability, but not beyond our scientific understanding. That means we would have no idea how to do it, by also cannot see any scientific reason why it should not be possible.
