What do they mean, if they don't mean being present in the future past their normal life span?

If you mean jumping into a swirling tunnel and being able to pick certain points in time, then no that's not possible.

That's exactly what most people mean.

"There is an old photo from the re-opening of a bridge in 194 where one of the people looks like they are dressed in a style that post dates when the photograph was taken. The caption reads: Reopening of the South Fork Bridge after flood in Nov. 1940. 1941"

Check the guy with the shades

Nevermind the shades, he's holding what looks remarkably like a digital camera..... :eek:

(compare what he's holding to the guy on the left front with the old box-shaped camera)

You sir are the nut, google Michio Kaku or put his name in youtube and you will see how ridiculous your claim is.

If you start from a still position and could accelerate to 99% the speed of light in about 5 minutes, then de accelerate back for another 5 minutes, 70 years would have passed on earth.;)

Fúck that, I'm having what you're having.

Time travel is possible. The hard part is obtaining a Klingon bird of prey and then getting your trajectory around the sun just right....

You can equate time travel to space travel - you don't need a teleporter that moves you instantly across great distances to be considered travelling - you can move through space by any means, no matter how slow or fast, and you're still travelling. Same with time travel.

Since there is no real form of time travel currently, what most people mean is what they see in science fiction. In fiction there are various different ways of travelling through time: Deloreans, cyro chambers, black holes, Kerr rings, wormholes, parallel dimensions, alien technology, supernatural intervention and, indeed, time travel via time dilation. There's also different mechanisms that aren't really time travel but affect the character's passage through time. The Queen of Hearts in Through the looking glass is moving backwards through time at 1 day per day so she's just doing what we do in reverse. In Dan Simmons' Hyperion series some of the characters use a device that does the same thing while they remain unaffected inside it. Kind of like the Tardis, which is also a device that travels through time at a greatly accelerated/reversed rate rather than having an instantaneous effect.

In the most famous story, H.G. Wells' The Time Machine, he talks about how, if you can control your speed you can move through time at a rate faster or slower than the normal one here on earth. This is pretty close to time travel via dilation.

He's travelled 1,700 years, no wonder he looks different to the rest.

Time travel is easy...just head down to Radionics or your local Maplan and grab an off the shelf Flux Capcitor!

we're all travelling through spacetime at the speed of light

If it is possible it is only forwards, never backwards.

i made a time machine next year, if it works i'll report back nine monthsv ago

It is indeed. I've time travelled myself, great place for a time travelling holiday Leitrim was

What if your mother is really attractive, like when she was young.
And she likes bad boys who play rock and roll music.

This is a very interesting video of a series called through the wormhole and yes thats morgan freeman narrating. They did an episode on time travel and its very interesting heres said video

-FF are in power
-Our titans of finance and enterprise are household names and self rewarded beyond their dreams
-One bedroom apartments in Dublin are €3m
-30 page property supplements in the Indo every Friday
-All the young wans are out snorting coke and maxing out their biometric credit cards (which are micro chip implants these days)

we've never had it so good, what could possibly go wrong...

You mean 2014.

Michio Kaku likes to talk a bit of crap to appeal to the masses. There's a reason his funding isn't going towards studying "time travel". It's because, based on our current understanding of physics, backwards time travel is 100% implausible, improbable and downright impossible.

But of course, if famous scientist guy says it's possible, it gets people interested in physics so it's a win/win.

These videos give a nice overview of what we're dealing with dimension wise when we say "time travel":

Wasn't there an experiment using a signal sent at a specific time in a controlled environment and it was set up to receive such signal aswell as before the sending signal was sent, apparently a signal was received BEFORE the original signal was sent (nano seconds) but this only happened when they sent a signal after sending a signal that had been received.

What would be the point in time travel if you couldn't prevent tragic events?

Typo Nit-pickers? Hmm, maybe.
Wonderful irony? Definitely.

the REAL question is, does time itself even exist?
