 The concept of a time machine typically conjures up images of an implausible plot device used in a few too many science-fiction storylines. But according to Albert Einstein's general theory of relativity, which explains how gravity operates in the universe, real-life time travel isn't just a vague fantasy. Traveling forward in time is an uncontroversial possibility, according to Einstein's theory. In fact, physicists have been able to send tiny particles called muons, which are similar to electrons, forward in time by manipulating the gravity around them. That's not to say the technology for sending humans 100 years into the future will be available anytime soon, though. Time travel to the past, however, is even less understood. Still, astrophysicist Eric W. Davis, of the EarthTech International Institute for Advanced Studies at Austin, argues that it's possible. All you need, he says, is a wormhole, which is a theoretical passageway through space-time that is predicted by relativity. [Wacky Physics: The Coolest Little Particles in Nature] |

I thought if you just zipped out into space for four or five years and came back, time on earth has progressed two hundred years. Didn't any of you watch planet of the apes?

I don't really want to pass through anyone's wormhole. Especially if it's warm.

The problem even if possible is that there is no proof of stabile wormholes. They too are only theory. Plus you would have no idea if the tail was also stable and fixed, or what time and place was on the other side.
