Stephen Hawking Explains How To Build A Time Machine

Stephen_HawkingCatharine Smith for Huffington Post:

Ever wondered if–and how–you could build a time machine?

Stephen Hawking, a self-described “physicist, cosmologist and something of a dreamer,” offers instructions on how to build a time machine in an article for the Daily Mail. “All you need is a wormhole, the Large Hadron Collider or a rocket that goes really, really fast,” the article promises.

Hawking roots his premise in Einstein’s theory of relativity, suggesting that since time moves faster in some places than others, it’s quite possible to move along this “river” into the future–but not back to the past.

“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.” Indeed, he recently wrote that humans should fear aliens and likened the inter-species exchange to what happened between Christopher Columbus and the Native Americans.

Hawking even suggests what he might like to do if he were able to travel through time: “If I had a time machine I’d visit Marilyn Monroe in her prime or drop in on Galileo as he turned his telescope to the heavens,” he writes. “Perhaps I’d even travel to the end of the universe to find out how our whole cosmic story ends.”…

  1. Stephen says you can only travel into the future, but would like to visit people in the past. Um, OK. Perhaps he needs to let his brain rest a bit.

      If you have a wormhole composed of “exotic matter” that would allow a human being to pass through it without being turned into spaghetti, you can move one end of the wormhole around and around in circles at close to the speed of light so that relativistic affects effect that end. The other end would stay in normal time.

      Traveling through the wormhole would be traveling through time.

  2. I read about this in The Times last week what I don't get is that if this space ship is going to travel at 99% of the speed of light where a day on board would be one earth year, how would you not crash into an asteroid or planet or something else that wasn't there hundreds of years ago when you set off, it's never gonna happen is it Stephen. Atheists believe some ridiculous stuff lol.

      If you are going that fast you would just demolecularize slightly and coast right through any solid object that would happen to be in the way. It is pretty common knowledge in time travel circles. Or you might just pray really loud.

      • yeah so you'd probably cease to exsist almost instantly, I don't think humans were designed to travel at that kind of ridiculous speed. It's never going to happen anyway we'll evolve before we could do it.

          You wouldn't cease to exist at all, you would be held together by gravity, just not particularly solid. It isn't exactly rocket science. What if we evolve into creatures that could by our very nature manipulate time and space, like Hiro Nakamura?

          • I think I'll stick to the traditional method of travelling to the future called “living” I'm not to sure about being a loosely held together human jelly for the sake of flying into the future, you would need a rocket scientist though to help build the big space ship. I'm guessing that Hiro bloke is that dude out of heroes I've not watched it so I don't know what it is he does to be honest but if we did evolve it wouldn't be us, they'll be laughing at us with our primative ways.

  3. i think stephen hawinks thinks too much but actually is pretty much fuckin usless,

    Why I get an erection everytime I read an article about Hawkin, spacetime, or the Universe?
