Are wormholes uni-directional?
-
It's late. Why are all the difficult posts made late at night. I don't get enough sleep as is, now I am compelled by the subject of this thread to answer it. Boy 7 am comes early... The short answer is no - they are not unidirectional. The long answer is still no, but of course, not so simple. When two singularities in a different space and/or in a different time fuse together, they form a tunnel within the fabric of space-time. However, this tunnel occurs fairly randomly throughout the universe and time and other universes. These wormholes connect different locations, galaxies and even possibly between or among universes, and different times, like one hundred years into the future or the past, depending what type of wormhole you have! There is also some slight problems associated with these wormholes. Wormholes are very unstable. By the time a spaceship or any object reaches the wormhole, the wormhole would have pinched off and the object would hit a singularity and would be, "drawn into spaghetti," or disintegrated. In order to let the wormhole to stay open long enough for anything to get through it, a negative curvature in space-time, or open space-time, must exist. The presence of negative energy would cause space-time to become open, since positive energy makes space-time closed. There exists quantum fluctuations in the subatomic level where in "empty" space there are continuously forming particles and anti-particles and "virtual energy" pairs of positive and negative energy particles where they annihilate each other once they seek their partner. These particles have been proven to exist and influence several events indirectly and have been hypothesized to show the existence of a black hole by the black hole's emission of radiation, where the positive energy particle has lost its partner, the virtual negative energy particle, to the black hole and the positive energy particle floats off into space. The virtual negative energy particle may be able to keep the wormhole stable enough to slip something through. Even if we have negative energy, we there is a problem with time as an object goes through a wormhole. According to Einstein's General Theory of Relativity, time slows down as the curvature of space-time gets more and more severe, selectively a black hole or a singularity. Wormholes have the same curvature as singularities do and may cause the problem that much time would pass outside the wormhole as the object goes through the wormhole, so when the object emerges, about a thousand years may have pa
Thanks John That was very interesting reading. So assuming we can stabilize a worm hole by somehow manifesting some negative energy then we are not actually travelling into the past, but rather we are stuck somewhere while the outter universe moved forward in time. And when we come out of it we are actually in the future, right? Egad! Nish

I think one of the best explanations of this comes from Carl Sagan: Ever since St. Augustine, people have wrestled with this, and there are all sorts of things it isn't. It isn't a flow of something, because what does it flow past? We use time to measure flow. How could we use time to measure time? We are stuck in it, each of us time travels into the future, one year, every year. None of us to any significant precision does otherwise. If we could travel close to the speed of light, then we could travel further into the future in a given amount of time. It is one of those concepts that is profoundly resistant to a simple definition.
One thing in favor of future time travel is that if time travel into the past had existed, we'd probably have seen some dude from 3050 coming back to warn us of something, say a flood :-) Nish

Never heard of the butterfly effect? :) You never know what changes when you change something (as a programmer you should know that). And, when he comes back to warn you, and returns to his time, wouldnt it have been unnecessary to go back, because he was already back? And if he doesnt need to return, because he was already, didnt he never go? :doh: :doh: Ahhh, my head is hurting. Dont you have any other questions? :confused:

The 'past' and the 'future' are all relative. There isn't one big uniform blanket of time - no single reference clock that keeps the entire universe ticking along at the same rate. Time is always measure relative to time at some other point. As soon as you or that other point experience differeing acceleration (ie you move or are affected by a gravitational field) then your time and their time will be different. cheers, Chris Maunder

I was reading the new edition of Hawking's book and there is an extra chapter on wormholes and time travel. The basic idea is that wormholes can be used as short cuts for jumping between two distant regions of space-time. But he sums up by saying that "so wormholes, like any other possible faster than light travel, would allow one to travel into the past!" But he doesnt go on to tell us why its only into the past. As fara s I see it, if person A can jump from point X (say on earth - present day) to point Y (say on alpha centauri - 2000 years in the past relative to earth) then what's stopping person B from doing the same (except he jumps to earth from alpha centauri thereby going forward 2000 years into the future).

I had read somewhere that if you have a wormhole connecting two locations (a simple tunnel, with no time-shift), and one of them is moving close to the speed of light, that their time-frames would go out of sync and they would not only connect two different locations, but two different times. If that is the case, then moving through a wormhole could bring you forwards or backwards in time (depending on which side you went into). ------------------------------------------ The ousted but stubbornly non-dead leader reportedly released an audiotape this weekend, ending by calling on Iraqis to, quote, "resist the occupation in any way you can, from writing on walls, to boycotting, to demonstrating and taking up arms." adding, "you know, pretty much anything I used to kill you for." - The Daily Show

If wormholes were uni-directional, then it would be illogical for time to be a dimension. Consider an object going through a wormhole from 2003AD to 203AD. Relative to the local universe it may have gone back in time. But it itself probably just went a small step ahead in time. If the object's relative time was taken backwards then the object would be back in 2003. The two main fields of thought on time travel to the future are multiple futures, or future convergence. Future convergence suggests that it is impossible for you to go back in time and shoot your great grand father as you would not exist to do that. Multiple futures suggest that you could thus their are multiple futures possible. With multiple futures the big problem with time travel is that you won't know which future you would be going to as it hadn't been decided. But future convergence solves this as their would only be one future possible. The one that had a record of you leaving. Regardz Colin J Davies

That just says no action has been brought against him, not that he did not enjoy phenomenal success on the exchange. Maybe no just cause could be found for such action, except the embarrassing theory that he did have insider (future) knowledge. The difference between a pessimist and an optimist is that while the pessimist is always a victim, the optimist is always a target. - Brady Kelly

So what is the definition of "The reports appear to be a hoax" 1) Andrew Carlssin , never existed ALL reports appear to be a hoax 2) Andrew Carlssin is a real person, but never but money on the stock market 3) Andrew Carlssin is a real person and made some money on the stock market 4) Andrew Carlssin is a real person and made a huge amount of money by insider trading 5) Andrew Carlssin is a real person, a time traveller , made a huge amount of money using knowledge of past events and the authorities are desperatley trying to cover up the truth. Quick Straw poll please :) Dave
