Steven Hawking says time travel possible

Quote:
He suggested humans could build spaceships capable of such high speeds that time itself would slow down for those on board.
...
It could enable humans to "colonise the future".
...
"I used to avoid talking about it for fear of being labelled a crank, but these days I'm not so cautious."
...
"It would take six years [to reach 98% the speed of light]."
...
"Each day on the ship would be a year on earth... a trip to the edge of the galaxy would take just 80 years for those on board."
...
Hawking dismissed the prospect of time travel into the past, pointing out it would create the so-called mad scientist paradox, where a researched could travel back in time and shoot his past self, raising the question of who fired the shot?
Time travel possible, but only moving forwards, says Stephen Hawking | News.com.au

comes a week after he said aliens exist.

ridiculously fucking interesting. not sure i'd be willing to give up 80 years of my life to see the edge of the galaxy, though.

indeed. if it's anything like a zoo or theme park it'll just be a chain link fence and a motorway.

Does he have plans for such a spaceship? because if not, I thought that theory of time travel was pretty common knowledge

Even though I think the idea of time travel is fun, I doubt it could ever happen. If so, wouldn't we have someone walking around today saying, "I am from the year 2500"?

Thats one of the points Hawking makes. Only forward time travel would be possible. If you think about it, it makes perfect sense. Except the whole pesky fast spaceship business

It's not like Hawking's saying anything new here, didn't Einstein already say as much?

i just think the whole thing is insanely interesting. i would have thought we're a bloody long way off making a spaceship that can travel at speeds of 650 million m/hr.

i could talk about this stuff for days on end..
