Not at all, and extremely unlikely ever to become so. Even with the wildest assumptions about inventions to come, the math is daunting -- and the inventions would have to be really off the wall before there's even anything to talk about. Scientific American did an article on the problems a few years ago -- sorry I don't have the cite, but it should be available.

The answer to this is bordering on teleportation, and although fumbling attempts have been made to make this dream a reality, we still have a long way to go. I have seen an episode in Discovery Channel when they covered the subject of Time Travel. A team of scientists were able to make a beam of light travel from one place to another. [Correct me on this one if necessary; it could have been a beam of photons or electrons or some other really tiny matter, but I distinctly remember it was a beam of LIGHT so I'll go with that.] It's not really safe to say that it's not possible. There was an idiot who once said that it would be impossible for the human race to go to the moon.

It's not currently possible. The "transporter device" on Star Trek "dis-assembles" every atom of the body, the transmits it to another location to be re-assembled. How ever the Heisenberg Theory of uncertianty, state's: A quantum mechanical principle due to Werner Heisenberg Eric Weisstein's World of Biography (1927) that, in its most common form, states that it is not possible to simultaneously determine the position and momentum of a particle. Moreover, the better position is known, the less well the momentum is known (and vice versa). Meaning unless the machine they use can predict and reconstruct to object exactly the object would be changed and could not be re-assembled. But than again, it was stated at one time that a 1 gig computer chip was twenty years down the road.
