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.'"
The Star Trek method makes perfect sense. Roddenberry & Co. didn't have the budget for establishing shots with shuttle craft and planetary atmospheric flight. They needed something that would be cheap to produce, not eat up lots of show time, and would have a good "wow" factor.
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.
Your ad here.
Science hasn't teleported squat. They've just caused one particle to mimic the quantum state of another. The number of particles at the source hasn't changed. The number of particles at the destination hasn't changed. So in what way was anything "teleported"?
When our name is on the back of your car, we're behind you all the way!
You're exactly right. In fact, the impulse is transmitted at the speed of sound in the stick.

I'm just assuming that everyone here knows this already, but for the one or two of you who don't know, the Heisenberg Compensator is the part of the ST transporter that deals with the pesky quantum issue of not being able to pin down the exact location of the subatomic particles whizzing around in Picard's body.
Of course it's physically impossible to make such a compensation, and when one of the technical guys on the show's staff (Okuda?) was asked how the Heisenberg Compensator worked, he replied, "Very well, thank you."
Sam! If you will let me be,
I will try them.
You will see.

Latinum cannot be replicated without being detected as "counterfeit." That's why it is used as a currency.
