Teleportation — Fact and Fiction

jcatcw writes "Earlier this week actor Hayden Christensen, of Star Wars fame, and director Doug Liman discussed teleportation with MIT professors to compare the reality to the special effects version in the upcoming movie, Jumper. Edward Farhi, director of the Center for Theoretical Physics at MIT, said, 'It's a little less exotic than what you see in the movie. Teleportation has been done, moving a single proton over two miles. [But] teleporting a person? That is pretty far down the line. The quantum state of a living creature is pretty formidable. That is just not in the foreseeable future.'"

    If I have a long stick and you hold the other end of it and I thrust my end towards you, you will instantly faster than the speed of light feel it at your end.

    Although it's a neat idea as a thought experiment with an infinitely rigid stick, in reality the effect cannot be faster than the speed of light as the force you apply accerlerates the molecules at the end closest to your hand first, which in turn apply an increased force against the next molecules along and so on until the force has propogated through the whole stick to the other end. As it's essentially forces accelerating masses, they must still obey special relativity and cannot move faster than the speed of light in a vacuum.
