Time Travel

The faster one travels the slower time passes for the traveler. This is a fundamental, if bizarre, entailment of Einstein's theory of relativity, and cosmologist Stephen Hawking, his brilliant mind still active despite a body wracked by Lou Gehrig's disease, thinks this makes time travel into the future possible.

Of course, this isn't a new idea. It's been the premise for movies like Planet of the Apes and others of that genre for decades.

Even so, it's interesting to read Hawking's thoughts on it and why he doesn't think travel into the past is possible. Read the story here.
