that the theory of time tunnel or wormhole can not only carry humans to other planets, if the wormhole at both ends of the same location, and time rather than distance, then the spacecraft can fly into, after flying still Close to the earth, just into the so-called distant past. Because in the 4-degree space, 10 minutes may be n hours. But Hawking warned, do not take time to go back to history.
Fly to the future
Steven William Hawking said that if scientists can build a spacecraft close to the speed of light, then the spacecraft will inevitably because it can not violate the speed of light is the maximum speed limit law, resulting in the cabin time slows down, then the flight is equal to a week 101 years on the ground, it is equivalent to fly into the future.
Hawking lift artificial satellite, for example, refers to the satellite in orbit, due to the impact of the Earths gravity is small, the satellite time is slightly faster than the ground time. As a result, Hawking envisioned a large speed universe ship, can be accelerated in 1 second to 97,000 km per hour, 6 years to accelerate to % of the speed of light, faster than the history of the fastest ship Apollo 10 times. The passengers on board the ship is disguised to the future, making a real time travel.
Four degrees of space
Even in space, everything has a length of time, in time roaming, means through the 4 degrees space.
Hawking, for example, pointed out that driving straight line is equal to the 1 degree space in the road, and turn left or right is equal to plus 2 degrees space, as in the meandering mountain road up and down, it is equivalent to enter the 3 degree space Crossing the time
