Wormholes are allowed to exist in the math of "General Relativity", which is our best description of the Universe. Source
The problem is that in order to traverse an Einstein-Rosen bridge from one universe to the other, a traveller would have to move faster than light at some stage of the journey. And there is another problem with this kind of wormhole, it is unstable. Source
All around us are tiny doors that lead to the rest of the Universe. Predicted by Einstein's equations, these quantum wormholes offer a faster-than-light short cut to the rest of the cosmos - at least in principle. Now physicists believe they could open these doors wide enough to allow someone to travel through. Source

Ghost radiation could therefore be used to offset the positive energy of the travelling matter, the researchers have found. Add just the right amount and it should be possible to prevent the wormhole collapsing - a lot more and the wormhole could be widened just enough for someone to pass through.
It would be a delicate operation, however. Add too much negative energy, the scientists discovered, and the wormhole will briefly explode into a new universe that expands at the speed of light, much as astrophysicists say ours did immediately after the big bang.

In 1994 Miguel Alcubierre Moya, then at the University of Wales at Cardiff, discovered a solution to Einstein’s equations that has many of the desired features of warp drive. It describes a space-time bubble that transports a starship at arbitrarily high speeds relative to observers outside the bubble. Calculations show that negative energy is required.
For now, such space travel remains in the realm of thought experiments. The CERN Large Hadron Collider in Switzerland is expected to generate one mini-black hole per second, a potential source of wormholes through which physicists could try to send quantum-sized particles.
But sending a person would be another thing. To keep the wormhole open wide enough would take a negative field equivalent to the energy that would be liberated by converting the mass of Jupiter.www.newscientist.com...
Ronald Mallett, Professor at the University of Connecticut, has used Einstein’s equations to design a time machine with circulating laser beams. While his team is still looking for funding, he hopes to build and test the device in the next 10 years. Source
hay im no skeptic, but this you must know is wrong, it cant work. This has been fed by that X NASA employee, its dissinfo. Anti-gravity or lift has to do with counteracting the strong force effect. All this is increasing the mass effect and creating a gravitational well and pro-gravity effect, not anti-gravity. As you know 3 single quarks create less mass, that 3 quarks together(strong-force) reverse the matter fields strong force effect and you should create anti-gravity.

If you venture into the subatomic world in an attempt to unveil its inner workings, possession of all the knowledge in the world is not enough. Instead, invite your imagination to serve as a guide, because many rules as we know them no longer apply. Just like the story of Alice In Wonderland, this new world may look familiar but it is not fully comprehensible. Scales shift and matter transforms. Transitory twins appear and extra dimensions hide A subatomic venture
1 So despite the Standard Model's effectiveness at describing the phenomena within its domain, it is nevertheless incompleteThe standard package
This was the accelerator that put the Standard Model of particle physics through its paces. The numerous data taken by the four experiments well and truly tested the model to an incredible level of precision. The experimental results agreed with the theoretical predictions and helped to establish the Standard Model's validity. Other notable achievements at LEP include establishing that there are three types of neutrino, and setting the lower limit for the possible mass of the Higgs boson.Testing the standard model
2 UA1 and UA2 were two experiments at CERN’s Super Proton Synchrotron (SPS) accelerator which started taking data in 1981 when the SPS first operated as a proton–antiproton collider. At the time, one of the hottest challenges in particle physics was the hunt for the force-carrier particles predicted by electroweak theory. Named the W and Z bosons, these were heavy particles, so finding them would require an accelerator that could reach an unprecedented level of energy. A noble discovery
3 At a special seminar on 10 February 2000, spokespersons from the experiments on CERN's Heavy Ion programme presented compelling evidence for the existence of a new state of matter in which quarks, instead of being bound up into more complex particles such as protons and neutrons, are liberated to roam freely. Theory predicts that this primordial soup of quarks and gluons known as ‘quark-gluon plasma’ must have existed at about 10 microseconds after the Big Bang, before the formation of matter as we know it today. The primordial soup
4 An atom of antihydrogen consists of an antiproton and a positron (an antielectron), which makes it the simplest antiatom. Unfortunately, this does not make it any easier to produce in the lab. Persuading the antiprotons and positrons to combine together was a challenge that no one had managed to solve until the PS210 at CERN created the first atoms of antihydrogen in 1995. The true story of antimatter
5 Researchers now believe that the gravitational effect of dark matter makes galaxies spin faster than expected, and that its gravitational field deviates the light of objects behind it.
But what is dark matter? One idea is that it could contain ‘supersymmetric particles’ - hypothesized particles that are partners to those already known in the Standard Model. Experiments at the Large Hadron Collider may be able to find them. Dark matter
6 Dark energy makes up approximately 73% of the Universe and appears to be associated with the vacuum in space. It is homogenously distributed throughout the Universe, not only in space but also in time - in other words, its effect is not diluted as the Universe expands Dark energy

Hasn't the theory of forward time travel been proven? At least relatively speeking. A spacecraft makes a 12 year return trip somewhere and due to relativety the crew age slower than those left on earth and when they return 500 years have past on earth but only 12 years for the crew of the space craft. So it's not a jump into the future but a slow down in time for the crew yet the outcome is the same?

When i do the easy geometry on time travel which you explain here, there is no way anyone can travel faster than time.
Three different object within same space/time will have the exact same time.
There is no way you can alter time to any of these three objects by creating a wormhole. The only thing you can do is shorten the time traveled to one of the two objects.

Watch part 2/4 of the special and general relativity, it makes a example very similar to what your askeing. Yes time would slow down on the craft depending on movement speed. If the craft could move with half the speed of light, time would also slow down to the half...1 seconds on the moveing craft would equal 2 second on earth. In theory you would stop time if you could reach lightspeed. It has been proven experimentaly that time slows acording to your moveing speed.....Atleast on atomic watches, that aint neccesary the same as stopping ageing of humans. Problem is that the calculations include speed of light which is a huge number. Therefore to get any use of this you would need to travel with extreme speeds.edit on 14-8-2011 by Mimir because: (no reason given)

Ok. If you watch video 2/4 pay attention to one thing:
When the light has to travel further the clock moves slower "correct?"
But there is something wrong with how the video displays this.
Shouldn't it look like this?
The only way for light to hit another ship that is moving with the speed of light. Is if the speed of light is increased to faster than light speed? Not possible.
If a satellite has to correlate its position it has nothing to do with actual time. But location.
If its location is off, then the distance has changed positive or negative compared to earth for instance. This can be monitored by pining the satellite.edit on 27.06.08 by spy66 because: (no reason given)

I never said a thing about the postion of the satellite. I said that due to relativity the time (Of day as in hour, minutes,seconds) on boared the satellite is slower than the time on the ground. This has been proven and the satellite is prgramed to take relativity into account when telling our GPS what time it is. The way I see it is you can draw pictures and and talk about light speed all you want but relativity has been proven and is accepted and the on boared computers make allowence for it. If relativity was wrong and if the time on the satellites wasn't behind the time on the ground due to the speed of orbit of the satellites our GPS times would be wrong because the systems on the satellites have been told to add a few seconds onto it's real time to allow for relativity. So the faster it goes the slower time flows. ( For it not us)
