The teleporter problem
I'm assuming you've seen Star Trek. How do you think the teleporters are supposed to work?
Science fiction writers and some scientists seem to think that there is no reason to assume that technology will advance to the point where some form of 'teleporter' will be possible. The theory goes that it will be possible for the receiver equipment at one end to completely analyse every particle of a body, including its state and its relation to every other particle in the body, convey this information to the (distant) transmitter, where an exact copy of the original object will be created while the original object will be disassembled into its component parts.
I have no problem with this theory, scientifically. It might just work someday. It will be great technology for transferring objects, but I wouldn't ever be brave enough to use it - even if it could be demonstrated to work perfectly. And here's why.
The thing is, if I was to use a teleporter, the machine would produce an exact replica of me at the transmitter end - a person with all my memories, my exact personality, my tastes and preferences, my beliefs - someone that, as far as the rest of the world would be concerned, would be exactly me. But it wouldn't be me as I would have been disolved at the receiver end. Although someone looking like me, with a conciousness idential to mine, would emerge from the transmitter, my conciousness would have been destroyed in the reciever.
What about you? Do you think that a teleporter could work, someday?
