"a traversable wormhole, one through which you could pass freely back and forth. In fact, for one solution, the trip through a wormhole would be no worse than riding in a plane.
There was a catch, though, that made such a wormhole impractical. Gravity would crush the throat of the wormhole, destroying any travelers trying to reach the other side. To stabilize the throat of the wormhole, scientists would need the repulsive force of perhaps the most exotic and speculative entities in the universe: negative mass and negative energy. Conceivably, using either could keep the throat open sufficiently long to allow astronauts a clear passage.
Scientists have looked for negative matter in nature, so far without success. One should note here that antimatter and negative matter are two entirely different things. The first exists and has positive energy but reversed charge. Negative matter has not been proved to exist. Negative matter is quite peculiar because it is lighter than nothing. In fact, it floats. Unlike meteors that come crashing into planets, drawn by the planets’ gravity, negative matter would shun large bodies like stars and planets. It would be repelled, not attracted. Hence, although negative matter might exist, we’d expect to find it only in deep space, certainly not on Earth.
Even if we could locate or create negative energy or matter, there is still a big problem: getting and manipulating enough of the stuff. Matthew Visser (pdf) of Victoria University in Wellington, New Zealand, estimates that the amount of negative energy needed to open up a one-meter-wide wormhole would be comparable to the mass of Jupiter, except that it would be negative. He says, “You need about minus-one Jupiter mass to do the job. Just manipulating a positive Jupiter mass of energy is already pretty freaky, well beyond our capabilities into the foreseeable future.” It might be millennia before we can even think about harnessing power on this scale.
Yet, if we ever do create them, wormholes could open the door to traveling not just in space but in time as well."
