Steven Hawking Explains How Time Travel Is Possible

Steven Hawking Explains How Time Travel Is Possible

Those who have ever entertained the idea that they could build a time machine, a self described ‘physicist,cosmologist, and something of a dreamer’ by the name of Steven Hawking has a few ideas that you might be interested in. He recently offered instructions on how to build a time machine in an article he wrote for the “Daily Mail.” “All you need is a wormhole, the Large Hadron Collider or a rocket that goes really, really fast,” Hawkings stated in his report.
The root of his idea comes from Einstein’s theory of relativity, stating that time moves faster in some places than it does in other places, and that he believes it is perfectly reasonable to think that one could move along those places where time moves faster into the future. He does not believe that travel into the past would be possible, though. This is because of paradoxes, for 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.” “I used to avoid talking about it [time travel] for fear of being labelled a crank,” Hawking admits. “But these days I’m not so cautious.”
Hawking feels that traveling forward in time would be possible of you could build a large enough machine which would carry enough fuel to propel it for six years at full power. That would bring it almost to 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.
