This is very interesting topic in regards to the multi-universe theory. A wormhole is, in theory, much like a tunnel with two ends each in separate points in spacetime. Albert Einstein's relativity theory set the speed of light as the universal speed limit and showed that distance and time are not absolute but instead are affected by one's motion. But Einstein wormhole opens briefly for incredible small period of time, and then pinches off. Anything that tries to get through it gets crushed and squeezes apart. Scientists began to investigate whether there might be the type of wormhole that is different from the Einstein's and is traversable. Michio Kaku, City College, NY says that to keep the wormhole open the negative matter is needed, but we also never seen the negative matter before, and that's a key to stabilizing the wormhole.
A clock in motion will always appear to run slowly compared with one at rest, because time is relative to the speed at which a body is moving. That fact would, in theory, allow for time travel—at least if you have a very fast spaceship.
Consider this: If an astronaut travels into space for six months at a substantial fraction of light speed and takes another six months to return to Earth, he would land in the future.
While a year will have elapsed on the astronaut's clock, tens of thousands of years may have gone by on Earth, depending on how close to light speed the astronaut traveled.But the laws of space and time as Einstein laid them out may be revised by the quirky rules of quantum theory.
This analysis forces one to consider situations...where there is a net flux of lines of force through what topologists would call a handle of the multiply-connected space and what physicists might perhaps be excused for more vividly terming a wormhole.
