Friedo pointed out a story by Larry Niven in which teleportation is common. Niven’s teleportation uses the “tunnel diode” method, which basically puts you in ONE place and spits you out ANOTHER without covering the intervening space.
It’s a Californian’s greatest dream. Less pollution, no cars, all the roads get turned into street markets…
…but in Niven’s excellent essay, “The Theory And Practice Of Teleportation,” he covers the “death chamber” model pretty well.
On “Star Trek,” basically, what the machine does is disassemble you, on an atomic level, even down to the point of mapping the exact location of every particle you have…
…and then annihilates you, turns you into plasma, and uses it for energy.
It then transmits that energy, reconverts it into matter, and reassembles it at a new location.
…so, yes, it destroys you and rebuilds you. You could make a pretty good case for the idea that Captain Kirk and Mr. Spock were dead in the very first episode, and we were seeing totally different people every time they beamed from point a to point b.
…and I’m inclined to agree with Niven. I wouldn’t ride in one of the damn things. Furthermore, it opens up the can of worms that says: what if you simply save the pattern and create multiple copies of me? Are they clones? Are they ALL me?
And what if I beam… say… Scylla, for example… from here to there… but instead of rematerializing him, I simply turn the machine off? I have destroyed Scylla! Am I guilty of MURDER? Am I still guilty of murder if I reconstitute him during a break in my trial? Or am I only guilty if I erase the machine’s “memory” that would allow Scylla to be reconstructed?
