Stephen Hawking says we're capable of time travel

[~~whimsy~~]

Famed astrophysicist Stephen Hawking believes humans are capable of time travel -- and he's not afraid to let everyone know.

Claiming he is not as concerned about being labelled crazy as he once was, Hawking has publicly aired his second startling theory in two weeks, after last week claiming it was "entirely reasonable" to assume aliens existed.

Preparing for the debut of his Discovery documentary, Stephen Hawking's Universe, which screens next week, Hawking said he believed humans could travel millions of years into the future and repopulate their devastated planet.

Hawking said once spaceships were built that could fly faster than the speed of light, a day on board would be equivalent to a year on Earth. That's because -- according to Einstein -- as objects accelerate through space, time slows down around them.

Which also means that Hawking's theory only applies to moving forwards through time.

Err, yeah...

I think his wheelchair has a few loose screws and is talking for him. Or somebody put a magnet on it and it is scrambling what he is originally saying.

Well here is the article. Enjoy.

You're damn right about that. But hey, people have done worse for a little attention.

I still like giving the benefit of doubt...so who knows? :dunno:

This is going to be a great thread.I can't say that I'm shocked I have always said he was walking that fine line of being a genius and insane :dunno:I'm just saying

Its scientifically sound. . .

 

[DJCowboy]

Actually a lot of physicists agree time travel is possible but requires such a powerful amount of negative energy that there is no way humans could do it on earth or even survive it. Something like a wormhole through space-time could do it but you don't know where and when you'll end up

I do remember reading if we ever came to the point of the capability of light speed travel, when the crew would return back to Earth, it could possibly be 50-100 years later. Of course unable to go back in time.

Of course, this is all theories, so hard to say what is and what isn't.

I mean to go into the future the damage is already done. Now if he comes up with a way to go back into the past and warn... now that will be problem solving.

Of course, if we come up with that, the future will bring back terminators in the form of toasters and try to electrocute many people who made huge mistakes in the past that altered the future.

As Trebus says; scientifically it is achievable. You just need to travel at the correct speeds in order make it happen (speeds that at the moment human beings cannot reach let alone survive if they were).

Of course you can only travel forwards in time, not back.

Who knows? I bet hundreds of years ago people would have laughed(thought you crazy) had you told them we could 'instantly' speak to someone in China/Africa from Europe/America(Cell Phone/Internet):dunno:

 

[pornophile]

Yes but we first need ships that can go faster than the speed of light. The amount of energy to do that is equivalent to 1 billion years of the Sun's total energy output. Or somewhere around there.

Now if he comes up with a way to go back into the past and warn... now that will be problem solving.

But all that would do is create a paradox. If you go back in time to warn about 9/11 and it is effectively averted, you no longer have a reason to go back in time to warn about it which would make it happen again. But this isn't possible because it did happen so which means no matter how many times you go back to warn about it you would have had to have failed each time in warning because 9/11 still happened. In other words, you cannot change the past. You may have always been a part of it, even inadvertently caused something to happen in history but that means you were always the cause. (an example would be to go back and just try to shoot Hitler before his rise to power but, with this theory, would have failed every time and who knows, maybe he thought you were Jewish and that's what created his hatred for the Jews) <This is a stretch example, I know, but it's just what came off the top of my head.

Or an incredibly brilliant man who knows what he's talking about...

Exactly, but this also means you have no free will. As you are part of history your decision to travel back in time has already been predetermined before you thought of the idea.

If we ever do build a time machine, it definately has to also travel through space. It doesn't make any sense when all these time travel movies show a person travelling 20 years into the future or past and ending up in the exact same spot on Earth. They completely neglect the fact that everything is in constant motion. The Earth around the Sun, the Sun around the galaxy, and the galaxy moving through the universe. I think even if you time-travel 1 day into the future within the same spot, you will reappear somewhere around Pluto.

But that was my lead up to the Terminator toasters

Technically we're already living in the future because of the time zones. Example where i am right now it's 8pm on the 4th may 2010, a time period that hasn't existed in America as of yet.

I can see what you are saying here.My whole thing with that is everything happens fora reason after World War 2 the United States became a Superpower not just a World power so history tells us if you kill Hitler or even warn the US about Dec 7,1941 what does that do to the status of the world or maybe I'm getting to deep into this.I'm just saying but then again we are only talking about traveling foward not backwards

Technically, time isn't relevant.

Everything happens for a reason? The slaughter of millions of Jews happened for a reason? To look at history this way is dangerous, as it could be a way to justify certain events. Just because an event led to a specific outcome it does not necessarily follow that that event happened for a particular reason.
