Scientists teleport two different objects.

I wish that I could understand this. I feel so pitifully incompetent not having any idea what they're really talking about.

That is wicked crazy.

Whoa, that's neat! I've heard of it being done with individual particles before, but never with a whole bunch.

As far as I know, it involves quantum entanglement (which has something to do with a closed system). Have you taken any physics courses? If you have, you'll know that there are a whole bunch of things conserved in closed systems (e.g., energy and momentum). Evidently, quantum entanglement involves "entangling" particles so that their quantum states are related.

So, on a really simple level, you can draw an analogue and see how their momentum would have to be conserved. Thing is, you can spatially separate the two particles before taking any measurements. Then, when you want to perform the "teleport," you measure the momentum of the first particle. Instantly, the second particle will have a corresponding momentum which fulfills conservation of momentum.

Granted, that's probably not quite how it works, although that's how I've heard it explained! (You're not actually physically teleporting anything, though, because nothing can go faster than the speed of light. You're "teleporting" information in the form of quantum states.)

Nothing can have a velocity faster than the speed of light, but you can travel faster than that, provided you don't actually physically cross distances. Teleporting means your information/particle/whatnot doesn't actually move across space with a velocity higher than c, it just disappears and reappears somewhere else. If you travel on the freeway, your velocity with respect to your destination point is probably something like 60mph... if you teleport to your destination, your velocity with respect to it is essentially 0.

Roughly. QM is messy, messy, messy. :)

Honey, nobody understands quantum mechanics/physics, not even the scientists themselves. xD You might be interested in a book called "The Dancing Wu Li Masters," though.

Although IMHO it should be considered better poetry than science. :-)

Well of course. I mean, nobody understands poetry either, including the poets. xD

As far as I can tell, the scientists and/or journalist didn't say what they're talking about --
"Zoom! Whirr! Buzzwords! Holy teleportation, Batman!"

In about the next 20 years, I betcha they would've clocked teleportation.
