Teleportation
"Almost a quarter of us believe teleportation can be achieved. Yes, disassembling our bodily parts to have them reconstructed in a new place, all without dying in the process. FACT."
The trouble with people is they don't get their (non)facts straight. Star Trek: The Next Generation gives a nod to how their teleportation device works in the episode where Picard is taken over by an energy being. He is teleported out into a "cloud" as "energy only, no matter" and is put back in his body by having the teleporter rebuild the last outgoing transmission and merging his "energy" self (that was in the ships systems by this time) with it. The doctor explained his memory loss as "this Picard didn't exist through the last three hours," meaning the body (and consequently the memories) had been dematerialized at the time of teleportation. The new body had been reconstructed from that transmission as if it had just happened. So, when we invent this form of molecular deconstruction and reconstruction technique, we'll, by definition, be able to clone people/body parts/etc automatically as well. Need a new body part? We'll "teleport" you, but merge your new body part into you during the reconstruction. Is it possible? Could be. Anytime soon? Not likely. It's that pesky problem of reconstructing all the atoms just so on the "other side" without having fancy machinery encapsulating you.
Which begs the question, if the teleporter in Star Trek can teleport from surface to teleporter, or from a point of the ship to somewhere else on the ship, why have a teleporter room? To serve as a "entry way" of sorts perhaps? Stargate had the proper idea with their "Asgard" teleporters, even if it was just as fanciful. :)
