Stephen Hawking may one-up me on space and time know-how....but I could totally beat him in an arm wrestling challenge! Either way Mr. Hawking explains how time travel to the future is possible (and totally not in my lifetime)...
Hawking says it would be possible if you could build a gigantic spacecraft, "a truly enormous machine," carrying a huge amount of fuel, enough to accelerate it for six years at full power. That would bring it to a velocity almost as fast as the speed of light.
"At this speed, a single day on board is a whole year of Earth time. Our ship would be truly flying into the future. The slowing of time has another benefit. It means we could, in theory, travel extraordinary distances within one lifetime. A trip to the edge of the galaxy would take just 80 years."
