Yeah, I could guess what you meant, but then again, travel forward in time by whose frame of reference? I suppose from your point of view, if you stopped in time and started up again, it would appear to you that you had skipped ahead in time...
So from whose point of view would you have jumped forward in time?
time travel has already happened...
russian cosmonaut who was up on mir is actually about 1/50th of a second ahead of everyone else...(or is that behind...can't remember...)...he spent something like 18 months in orbit zooming around at 17000 mph which was enough to have measurable relativistic consequences...not real exciting from a scifi point of view but...time travel nontheless
also...black hole, worm hole manipulation is theoretically possible...one simply needs a large enough amount of antigravity...gravity is your big foe when you're dealing with wormholes/blackholes...just conteract it with an antigrav field large enough to step through and voila...a portal through space...it's not out of the question to move the end of the wormhole in a manner as to alter the when and well as the where...
btw...given current technology..we could produce enough antigravity to hold open a stable wormhole...we'd just need a particle accelerator the size of the solar system to do it...
btw...i'm no expert...but i did read this months popular science...

"Let's Do the Time Warp Again
The science and the fiction of time travel are weird. But the science—courtesy of Einstein and others—is much weirder. "
i should have also mentioned that the theory that this is based on is that blackholes create such a distortion of space/time that they may in fact have other sides...that is...companion black holes somewhere else in space/time...which gives you the potential for blackholes to in fact be wormholes...you just need to stick your finger in and pry it open...
the article also suggests that rapidly spinning parallel cosmic strings could possibly be used as a time machine...(course they didn't mention how to find 2 parallel cosmic strings let alone get 2 of them to spin rapidly about... ;)
Obviously, it would be from the time-traveler's point of view.Quote:

By the way, I don't believe that theory is true. I see no relationship between velocity and time. Like I said before, it has been posted in the general chit chat section that the theory of relativity is under serious review. I think they're going to find it's flawed, if they haven't already.
Have you read about the cesium clock time dilation experiments? As far as time dilation is concerned, we have evidence that it is true.Quote:

BTW, I think General Relativity is probably no more flawed than Newton' laws of physics. It is based on observation, therefore as we are capable of observing more and more we're just updating what we know.
I guess but if he fails the time traveller might die or at least end up who where when or where.
I read about a study conducted by NASA and a few other space agencies that looked into this problem. All the geniuses involved decided that, yes, it would be possible but it would require something that resembles a "warpdrive" straight out of Startrek in order to travel significantly faster than the speed of light. They also concluded that this would, while theoretically, be possible would, also theoretically, require all the energy in the entire universe to run, which if ever built and operated would destroy the universe and everything in it including this "warpdrive".
So after years of study it was decided to leave time travel to future generations who, when we are all long dead and gone, could travel back to our "time" and using their wonderfully advanced technology prolong everybodys life so that we would never die.
Of coarse this would lead to a whole new problem of over crowding on this planet we call home, but thats a different matter to be worried about another "time". :D
(You don't get the joke, do you?)
Not so dramatical... You're talking about time dilation. Time dilation stuff can be found here: http://www.fourmilab.ch/cship/timedial.html . It's the well known thing that the faster you move the slower the time goes on (so the cosmonaut is at our point of view younger than he should be ;)).Quote:

BERBURT: Isn't that exactly about what they are talking about in the Teleportation thread (http://www.antionline.com/showthread...hreadid=218534)? You should take a look at it, too. And I think the interacting things are the quantum spins, not atoms'. A very fascinating thing, though.Quote:

so think of it like this you have 2 atoms that attract each other
if u change the charge of course 1 atom has a more positive charge and the other has a more negitive charge. if u were to change the charge of 1 the other similtaniously will respond with the opposite.
now they say that u can have these atoms in lets say different galaxys.
say it would take light 1000 years to travel the distance
but if u change the charge in the atom the other would respond intantaniously
I think we all should watch the Back to the Future -movies now again. :D
To all my learned compatriots - I believe I have found a real blackhole.
Isn't a general description a place where nothing that enters escapes and there is no light?
Voila. Our accounting department is one such place. Whole paper trails of companies have disappeared into its forbidding entrails. <I'm thinking of Sarlaac's pit in return of the jedi>
Why just the other day several staff members went to it never to be seen again....
