Famed astrophysicist Stephen Hawking believes mankind is capable of time travel.
The key he claims is light speed travel sighting Einsteins theory that as objects accelerate through space, time slows down around them.
According to Hawking’s math, a day on spaceship traveling light speed would be equivalent to a year on Earth.
“It would take six years at full power just to reach these speeds,” Hawking said. “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 traveling at 90 per cent of the speed of light.”
“After another two years of full thrust, the ship would reach full speed, 98 per cent 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.”
Why would we want to do this? Hawking’s reasoning is that if the earth is ever devastated, humans could travel into the future and return years later in the future to repopulate the planet. This would ensure the survival of humankind on the one planet we know to be capable of sustaining life.
Can’t we just go back in time to prevent what cataclysmic we’ve doomed our big blue planet? Unfortunately, Hawking’s theory only applies to moving forwards through time.
Moving backwards is impossible, Hawking says, because it “violates a fundamental rule that cause comes before effect. I believe things cannot make themselves impossible,”
Theories are great but where’s the science? According to Brian Cox a professor from Manchester University, experiments from Geneva carried out by the Large Hadron Collider has provided some backing results:
“When we accelerate tiny particles to 99.99 per cent of the sped of light in the Large Hadron Collider at Cern in Geneva, the time they experience passes at one-seven-thousandth of the rate it does for us,” Professor Cox said.
Hawking’s most famously known for his bestseller “A Brief History in Time” admits he is obsessed with time travel.
“Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a crank,” he said in Stephen Hawking’s Universe. “These days I’m not so cautious.”
It’s been news gathering string of theories lately for Hawking. Proclaiming that god dioesn’t exist but aliens likely do. Now proclaiming the feasibility of time travel were left wondering what’s next? How about looking into the future to see what’s going to devour our planet so we can avoid the whole mess in the first place?
