Interesting subject, userque. Thanks for the links. Unfortunately, I do not subscribe to Discovery Science and won't be able to watch this episode tonight, but I'll figure out a way to view it later on. I only have the regular Discovery Channel where most of the time everyone is Naked and Afraid.

I recently watched the movie, The Theory of Everything, about Stephen Hawking and just find it fascinating the way his mind and others, process the world and come up with their theories on the universe, time, space ... I borrowed from the library his book entitled A Brief History in Time...I read the first chapter and felt myself getting sucked into some vortex. I think I'm going to have to read a chapter, let it marinade in my brain, and then reread the chapter again. It's all good!

"So one can ask, how fast does one need to go, in order that the time for one observer, should go backwards relative to the time of another observer. The answer is given in the following Limerick.

There was a young lady of Wight,
Who traveled much faster than light,
She departed one day,
In a relative way,
And arrived on the previous night."

Let me know if you can't acquire the episode. I'm certain I can help you with that.

The study of time travel, especially into the past, is one of the most intriguing and mind blowing ideas I know. This is why I have been taking physics classes at the local university. My last 2 classes had to do with quantum mechanics. I wrote a essay called "Back to the future" in one of them. Its pretty technical in parts because of the physics but a lot of it deals with the paradoxes of backwards time travel. My final conclusion....it probably isn't possible until we have a theory of "Quantum Gravity". "Closed Timelike Curves" or CTC's at the quantum level are the key. Wormholes using "negative energy" is another but wormholes are better suited for traveling to across the universe.

I found the idea that even if you went back in time then you couldn't change history is popular. It would have to be consistent with history is a common belief among physicists like Stephen Hawking.

Another idea that they didn't discuss is the "Many Worlds" theory. It says infinite universes exist and every possible scenario exists in one of them. So, if you were able to go back in time you would really be going to another universe where you could change things but it is a different universe.

I love this Stuff! My favorite time travel movie is "Back to the future" but I love to watch them all. The paradoxes traveling back in time can cause is so interesting.

I would love keep this tread going. Hope others are as interested.

there is also the concept of the time value of money, which is how interest on your mortgage is calculated. if time equals money (i.e. if i had money i would not need to waste my time going to work to trade time for money), and my tsp account value is any indication, then yes, time can definately go backwards. it's all relative.

oh, and also, i once met a girl from nantucket. but i am not going back there.

ok, ok, i'll go there.

i once knew a girl from nantucket,
just sittin there on her bucket,
she gave me a grin,
but it was a sin,
in the end i just wanted to **** it.

there, now doesn't that take you back to 8th grade? see how time travel works? it's in your mind.

Clester,

Have you seen the movie Primer? Its a low budget, made in the mid-2000s, I think its my favorite TT movie. I think it pops up on Netflix streaming everyone once in awhile, though not there now.

my first post!

One time a buddy and I went to get haircuts. I couldn't help but listen as my buddy explained to the nice young hotly dressed stylist (it was Vegas) that he'd recently traveled to S Korea and back for a work conference. He said the travel was long...he flew over the Pacific to get there and over the Atlantic to come home.

The stylist said "you can't fly from the Far East to the US over the Pacific because that would make you go back in time and you can't do that". My buddy was at a loss for words after that. Bless her heart.

Yes I have. It was good. Most movies don't really go into the physics part. Interstellar did but not backward to one travel.

All you need is 1.21 gigawatts and a flux capacitor

I'm sure most of you have heard about the "Philadelphia Experiment", urban legend some claim is linked to Einstein's UFT?

LOVE through the wormhole... although some of them can get fairly repetitive as they repeat a lot of stuff.
