Time travel is the subject of a new mini-series by renowned physicist Stephen Hawking. Time machines are laughed at in the scientific community, but the noted astro-physicist says that the devices are not only possible, but have already been demonstrated. Check out the full story, with pictures and video below!
The physicist said that time travel to the future and the past are two completely different stories. To travel to the past, one would have to stabilize and expand a wormhole. Wormholes, predicted by Einstein, are apparently very real and very unstable ‘holes’ in the fabric of space-time that occur everywhere. But they are so small and last for such a short time, they cannot be seen.
Hawking’s time machine mini-series dismisses the theoretical use of using wormholes, and therefore all time travel to the past, because such an event would create what he calls the “Mad Scientist Paradox” where a man travels to the past and shoots himself.
There is hope, however, for travelling to the future. He says that creating a ship that would travel at 99.9% of the speed of light would experience time at one seven-thousandth the normal speed.
“It would take six years at full power just to reach these speeds. After the first two years it would reach half light speed and be far outside the solar system. After another two years it would be travelling at 90% of the speed of light,” he said. “After another two years of full thrust the ship would reach full speed, 98% of the speed of light, and each day on the ship would be a year on Earth. At such speeds a trip to the edge of the galaxy would take just 80 years for those on board.”
It may seem like a lot of work just to save a few years, but the main application of this would be reaching distant planets within a few generations of human life. You also have to consider that the ship would have to carry double the fuel needed to accelerate to the speed of light, as it would need just as much to slow back down!
Also, while it may only take a few lifetimes for the astronauts travelling to the new planet, about 2.5 Million years will have passed here on earth according to scientists supporting his theory.
So, as usual science breaks frontiers talked about in science fiction books, but just in a completely different way than we imagined. What do you think of Stephen Hawking’s time machine theories? Do you think it would be practical to travel to other planets in the way he described? Let me know in the comment section!
