STEPHEN HAWKING: How to build a time machine

Daily Mail ^ | 05/05/2010 | Stephen Hawking

[SeekAndFind]

Hello. My name is Stephen Hawking. Physicist, cosmologist and something of a dreamer. Although I cannot move and I have to speak through a computer, in my mind I am free. Free to explore the universe and ask the big questions, such as: is time travel possible? Can we open a portal to the past or find a shortcut to the future? Can we ultimately use the laws of nature to become masters of time itself?

Time travel was once considered scientific heresy. I used to avoid talking about it for fear of being labelled a crank. But these days I'm not so cautious. In fact, I'm more like the people who built Stonehenge. I'm obsessed by 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. Perhaps I'd even travel to the end of the universe to find out how our whole cosmic story ends.

To see how this might be possible, we need to look at time as physicists do - at the fourth dimension. It's not as hard as it sounds. Every attentive schoolchild knows that all physical objects, even me in my chair, exist in three dimensions. Everything has a width and a height and a length.

But there is another kind of length, a length in time. While a human may survive for 80 years, the stones at Stonehenge, for instance, have stood around for thousands of years. And the solar system will last for billions of years. Everything has a length in time as well as space. Travelling in time means travelling through this fourth dimension.

Every once in a while a W.C. Fields aficionado or a fan old film comedies will get a chuckle out of it.
I like to respond with “I’m a railroad man and I get up early in the morning.”

As a kid I use to think where I would go if I could go in a time machine.

Always thought it would be cool to take a trip on a wagon train or a clipper ship.

Of course I would have to make sure it was the Donner Party or the Mary Celisse.

[mware]

make that NOT the Donner Party or the Mary Celisse

He is (Hawking) a liar as usual.

[brytlea]

I really only want to figure out how to put myself thru one and come out about 25 years old.

[Bloody Sam Roberts]

I work with a guy named LaFond. I give him the precise spelling of his name (A la W.C Fields) at least once per week.
Drives him nuts. Which is why I do it, of course.

If we had a time machine, would could give his mother birth control pills.

Nice comment...Why would you ever consider saying such a thing? Let me guess, you also claim to be a christian conservative, right? No wonder the left calls us hypocrites............

Just couldn't bring yourself to say "abort him" could you..........that would have given you away.

All you need to time travel is an Infinite Improbability Drive.

I'm putting my money on the Oscillation Overthruster.

Time’s not a dimension - It’s a derivative function of state change.

[Richard Kimball]

This article is virtually plagerized from Gamov's Mr. Tompkins in Wonderland which was written in the 1930s or 1940s.

I'll take your word on that one. As I worked through the article, it became apparent that he did a few ducks and dodges. He implies the speed limit is the speed of light because if something went faster than light it would break the rules. Say what? Similarly, we can't travel backwards in time because it would create a paradox. That sounds a lot like he's breaking the old experimental science rule that you can only invoke the tooth fairy once.

There's got to be a reason beyond "it breaks the rules" or it creates a paradox.

He said radiation from the other end of the wormhole (time waves?) will create a feedback loop that keeps the wormhole from forming, sort of how a microphone picks up the amplified sound from a speaker and amplifies it again and again and again.

I don't know how credible that sounds, but it sounds better than the "My future self killed my older self before I could open the wormhole" paradox.

When we find one Hawking can go first.

[Jeff Chandler]

Why would you ever consider saying such a thing?

His values, not mine.

You know, you make an excellent point. The secular worldview compels the in-womb destruction of the physically flawed- the ultimate irony, LOL!

Go to the bottom of this page to use this Relativity Calculator. Enter some value such as .9 or .99 or .999 and click the button labeled 'C'=1 to see some really interesting relativistic-effects values.
