Travelling in to the Future - A Reality???

Recently i was watching an Documentary on Discovery channel, a very good documentary about Travelling into future by Stephen Hawking. I just want to share this with friends

According to Stephen Hawking, one of the world's smartest physicists, time travel might be possible. Hawking doesn't hold out much hope for time traveling through wormholes, even though he muses about the fantastic conditions that might someday make them work. Nor does he think we'll ever be able to travel back in time, because of paradoxes. His example: "What if a scientist travels back in time and shoots his earlier self? He is now dead. So who fired the shot? It's a paradox."
Traveling forward in time is another matter. 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."
 Unfortunately, this would probably be a one-way trip. Or, this advanced civilization could build a ship with a fuel tank that's many times bigger, and once the ship reaches its destination, it could turn around, accelerating back toward Earth at that same speed. But then by the time they arrive back home, another method of time travel might have already been invented.

If you got any chance to watch that documentary on Discovery channel, watch it calmly.  They are showing variety of methods and explaining how Time travel is possible.

For ex: If we sit in a train which travels at an speed of 3,00,000 Miles per sec., and it rotates the earth 7 times per sec (at its peak speed) at that time inside the train on the law of physics everything becomes slow. so if the train travels 50 years and stops at a place the passengers inside can feel only 7 days in their life. so after a week they board at destination they can see a different world which is 50 years forward. like that the explanations move on. Watch that documentary by searching its time of broadcast.
