the particles which make up the atoms and molecules of your body have a overwhelmingly most probable location, where you are right now. But, potentially, each of those particles have a small possibility of being somewhere else. IF you could shift the most probable location WITHOUT losing structural coherency...

Interesting from a conceptual standpoint or as a visualization, and I agree that that form of 'teleportation' would be preferable to the scan-send-rebuild method, but it is actually simpler to take a known volume of space and bend the spacetime continuum at the interface between it and the starting point, and then 'allow' it to exist instead at the end point. When applying this method, it is currently being argued whether or not the endpoint volume should be swapped with the startpoint or simply replaced with it, but some are arguing that that makes the overall method overly complicated. However, there could conceivably be times when that would be preferable, as in placing a science package inside a sun. You would not want to have that particular volume suddenly exist at the startpoint, as it would definitely be distinctly uncomfortable to be standing anywhere near it.

So is that what the article was referring to when it said, "Over the last few years, however, researchers have successfully teleported beams of light across a laboratory bench"? Were these beams teleported instantaneously?

Actually, they really weren't "teleported" in the way most people think of teleportation, as much as probability-filtered. Nothing really exists in a particular place until measured, but exists as a number of probable locations centered around a point in space. The alternate locations become more and more improbable as one goes further from the center of likelihood (reasonable probabilities are normally scattered across an area that is very sub-atomic in diameter). What they did was place a very thin material in the light path, and noted that some very few of the photons were skewed towards the "leading edge" of the probability sphere, making them arrive at the detector before the center-of-probability photons did, mostly by the amount of time it would take for the photons to have travelled the thickness of the material - implying that they skipped over it. In a sense, the "teleportation" effect was caused by the elimination of alternate possible locations.

By the same token one could order up and have a new YOU created. On the one hand maybe it would copy all of your memory; on the other, it could be a clear slate that looks like you.

It certainly wouldn't be a clean slate. notable portions of your responses are based upon how the brain is wired. neurons grow into specific confirurations.

What I really love is the way these scientists think that what they're working on is of any interest whatsoever to a normal person.

We watch Star Trek and think the transporters are cool. These dorks get a photon to "teleport" a distance of maybe twice its diameter in a lab and in their minds it's the same thing.

It's like humanity's interest for decades or longer in life on Mars. Martian canals, Barsoom, War of the Worlds invaders fill peoples imaginations. Then you see some geek at JPL gushing about their efforts to find "life on Mars!!!" - and they're talking about fossilized microbes or something!

They seem so desperate to be relevant that it's pathetic.

Yes. In an earlier experiment by John Bell (not teleportation, but related), two particles were sent in opposite directions, and then something was done to one of them. The other reacted faster than the distance between them / the speed of light.

If you are referring to the experiments I am thinking of, then it was really one photon split and sent to two different places at the same time. When one part was measured, the other part altered too.

I'm refering to memories. You're not born with them, and a freshly-built brain wouldn't have memories intact. Responses, instinct, etc, cure, but I'm not talking about those.

What's reassembled is no longer you, it's a "new" you.

How is this any different from what is happening to each of us on a daily basis. That is, atoms that comprise our bodies are constantly being cycled in and out of our system as we shed our skin, eat, excrete, inhale and exhale. Consider an individual that goes into a coma and wakes after 10 years. Practically every atom in his body will have been replaced. The same thing that would happen during teleportation, except at a somewhat slower rate. Are you telling me that the individual waking up would not be the same as the person that entered the coma. The same could be said about all of us, whether in a coma or not.

No offense, but what kind of logic is that?

Cellular replacement happens a little at a time, not all at once, which in this case would tear apart the entire person all at once. There's no disruption of the electrical routines of the brain, no transformation of matter into energy--it's a slow death and replacement of cells, not atomic dispersal.

If you can't see the difference between cell-by-cell replacement and complete disruption at the atomic level--that's called dying--then what's the point in going on? Thanks for the chat up to this point, though.

The whole disassembled/reassemble method isn't practical, but perhaps a stargate of some sort would prove to be workable...

The premise behind the Stargate is a demolecularization of whatever passes through it into the wormhole...then being reassembled at the other end. Same basic principle...assuming, of course, that it's possible.

I thought the stargate writers understood the principle of how a wormhole functions, it doesn't seem that they do.

I have that thought whenever I hear McKay or Carter explain how the Stargate works. Technically, it isn't a wormhole that forms between gates. But hey...Amanda Tapping could tell me the moon is made of green cheese and I'd believe it.

No, no, no. If you have ever read The restaurant at the end of the Universe you would know that teleportation is dangerous. Get the book and read the lyrics to the song "If you have to take me apart to get me there, I don't want to go". This will make you a believer in NOT having transporter devices:)

Well, it wasn't so much an attempt at logical debate as an attempt to provoke a philosophical discussion concerning the embodiment of the soul, but it seems to have gone over your head. Sorry if I caused you any mental stress.

Cellular replacement happens a little at a time, not all at once, which in this case would tear apart the entire person all at once. There's no disruption of the electrical routines of the brain, no transformation of matter into energy--it's a slow death and replacement of cells, not atomic dispersal.

You are throwing up a kind of straw man argument, by assuming that there would be disruption of the electrical routines of the brain, but the underlying assumption of the teleportation theory, by you own admission, is that it would produce functional, thinking beings on the other end. However, if the "electrical routines", as you say, of the brains of individuals being teleported were torn apart or disrupted, to use your words, then they wouldn't be functional, they would be, again in your words, dead, which would contradict your whole argument that they would be different, but still functioning individuals.

Unlike you, I'm not going to paraphrase this by saying "No offense", but I have to throw your question back, "What kind of logic is that?"

Speaking very loosely, teleportation will involve a similar loophole that prevents its use for time travel: the "jump" itself will be instantaneous, but setting up the jump will involve exchanging information no faster than the speed of light.

And would you have to set up each jump individually, or could you set up some kind of permanent infrastructure that things can go through? In other words, say you wanted to jump something over a disance of one light year. It would take a year to set it up, but once it's set up, could you then send information back and forth instantaneously without having to set it up each time?

Is this what's know as the tunnelling effect, or is that something different?

And if I understand you correctly, does this actually mean that the photon was registered to have arrived prior to the point that it would have been traveling at the speed of light? Is there a theoretical limit to the speed at which this could happen? For example, if you used a reallly long-wavelength photon, could you get a signal to go 20 feet in the time it would normally take to travel two inches at the speed of light?

The premise has morphed a bit a few times. remember early on when everyone sort of fell out of the gate at the other end?

in any case, the gate itself with its "event horizon" complicates things. Perhaps the gate is a teleporter which utilizes wormholes. Note that EM goes both ways through a gate, but matter doesn't. /geek

Yes. It got there before it "should have".

Not really, though the energy reqirements hit ridiculous rapidly.

For example, if you used a reallly long-wavelength photon, could you get a signal to go 20 feet in the time it would normally take to travel two inches at the speed of light?

Light travels the same speed regardless of wavelength, so that factor is not relevant. In the case of the experiment, it would be more like one or a few photons from a coherent light (laser beam) skipped forwards a measurable, but nearly meaninglessly small distance once during its path. The overwhelming number of its companion photons having failed to make the trip past the material.
