If they can, they've already done it.

TIME Travel? How absurd ... if we've lived from today to tomorrow, we've experienced time travel ... getting back to something already traveled? Well, that's the essence, isn't it!

[Kickass Conservative]

WOW, you're right. Im doing that right now, right now, right now, right now, right now, right now, right now,
right now, right now, right now, right now, right now......

HELP ME!!!!!!!!

My grandfather, who lived to be eighty-three, always said he would never go back and change a thing. I think he believed that all actions run consecutively and that if you change A, you can't have B. And if that was true, he wouldn't be sitting there in his recliner at a ripe old age saying "I'd never change a thing."

Interesting. My explanation for the paradox is that while we may be able to travel to the past, we may not be able to interact with it's environment.

The article's theory is probably the better explanation, however.

could I travel back in time to save a life? like Vince Foster's

It's useless if it doesn't involve looking into the future to grab the lotto numbers.

[MHGinTN]

Depends, eh? Grab the lotto numbers, collect millions, die eventually... what have you personally gained? If there is something about you that is not bound by spacetime as you seem to understand it, what have you actually gained if you reject the Lord of Salvation for your selfish directives?

How else do you explain Billy Ray Cyrus? ;)

You haven't been paying attention, pal.

Billy Ray Cyrus is alive, well, and although he isn't selling millions of CDs, his daughter is.

Miley Cyrus is the star of the Disney Channel series Hannah Montana (about a Tennessee girl's big break singing in Hollywood), Billy Ray plays her father, and the soundtrack to the show hit #1 on Billboard's Album chart and has sold over two million thusfar -- more than -- among other artists with 2006 releases -- the Dixie Chicks.

If you went back in time and met your teenage parents, you could not split them up and prevent your birth

OK, I buy that - but how about if I met Al Gore Sr and Pauline LaFon and split them up? Or Hugh Rodham and Dorothy Howell? Or Virginia Cassidy and whatever horny bum was around at the time? Would that have worked? Life would be different!

Oldie but goodie bump

[Lancey Howard]

Clearly, the present never is changed by mischievous time-travellers: people don't suddenly fade into the ether because a rerun of events has prevented their births - that much is obvious.

Okay. Have to stop there. It is not obvious at all. If mischievous time-travellers changed anything, nobody would ever know.

Larry Niven wrote a short story, "Rotating Cylinders and the Possibility of Global Causality Violation". Any civilization that gets close to building a time machine suffers a natural catastrophe that prevents completion.

These guys are from the PT Barnum school of flimflammery. There is no such thing as "time" in and of itself, it's KINETIC ENERGY at some rate(t=dKE). Can you think of a "time" event that is NOT a Kinetic Energy event going on at some rate? $1000 in small, unmarked bills in a brown paper bag to the first person to do the demonstration.

Really, you have to laugh at these four flushers. Picture one of them at the high stakes poker table in vegas. Stud poker, 3 players left. Our FOUR FLUSHER is #3 and has 4 spades showing, which wins the hand against the other 2, IF he has a spade in the hole. There is $300,000 in the pot.

So, instead of showing his hole card he goes into this long alternate universe spiel about probabilities, and claims 1/4 of the pot($75,000)because that's the 25% probability that his hole card is a SPADE.

Now, what is the probability that his tied up/living body will be dumped in a hole(as a HOLE card)out in the desert, using a SPADE?

We cannot know whether the present has been changed by something happening in time travel because if something is changed then everything is changed including all memories.

[RightWhale]

Einstein's Relativity always allowed time travel. What is weird, among many weird paradoxical results from solutions is that if the astronaut returned to his starting point not only would his clock read different, but it would be running at a different rate.
