Time travel will one day be possible says Stephen Hawking

Steven Hawking has been quiet until now: He said that he was afraid of being labeled a crank by other scientists-- HELLO the man is Steven Hawking-- the Einstein of our age??!! He decided to come out now and make a prediction that time travel will be indeed possible when our space craft engineering is able to keep up. If a spacecraft is able to travel fast enough ( 650 million miles per hour) that will be equivalent to 1 year on Earth. He didn't say anything-- at least in this article-- about traveling to the past-- assuming this is correct-- we can only travel to the future.Back to the Future!
