| 329466 | 2005-03-03 08:42:00 | I've read some stupid posts here in the past but this definately takes the cake! Not bad for someone that wants to know why men can't have babies. Or are you just trying out for the dumber than dumbest post |

Storage of just the postion elements (which is probably not enough) which might be possible in one atom of carbon . For a human, that would require a diamond crystal of about a cubic mile . And you'd need one for each end . So mapping is out? :help: That leaves us with transporting your body . This requires disassembly and then reassembly in another place . Without errors - see "The Fly" . But strange things are possible at the quantum level . Unfortunately I can't remember the theory which showed teleportation is possible . It was derived from the knowledge that quantum particles (bits of atoms if you like) can affect each other at large distances . For no obvious reason . Furthermore when I was at school, we were taught that matter can neither be created nor destroyed . Well, the collision of matter and anti-matter is pretty close to total destruction . And even more fascinating is the finding that space is not empty at all . At any moment particles are winking in and out of existence - from seemingly nothing . So matter is created . Apparently they are constructed by the warp of space/time itself and originate (I think) in the quantum foam of which our universe is fundamentally made up . And of which gravity is an everyday effect we can observe . So if particles can appear and disappear then maybe you can too . I hasten to add that I'm an amateur and don't pretend to really understand this but it is fascinating . |

| 329468 | 2005-03-03 22:29:00 | Why not just get in the damn car and drive from point A to point B? Infinity be damned, Haven't you people seen Event Horizen?? Muhahahahaha. No clue as to what the heck your all on about, Though Mote in Gods eye is an excellent read, the rest of the guys work pales in comparison. |

| 329469 | 2005-03-04 04:29:00 | Scientists have supposedly found that random matter appears and disappears in a vaccuum, which pretty much fits with what Winston said. Anyhow, if you could get a gravitational force strong enough to physically warp space, travelling long distances in just about no time would (in theory) be possible. The only problem is (aside from where you would get such a strong gravitational force), just because you warped space and brought a spot normally 10,000 lightyears away to your front door, who says you'll end up travelling back with that spot when the gravitational force is deactivated (as it would have to be). I'm rambling into things I don't know about now, anyway... |

You can only change its form . (heat/light/radiation etc) . Have read a book that explains Quantum mechanics for the layman . It also quoted someone or other whom I can't recall that . . "if you understand Quantum Physics, then you haven't grasped the concept" or words to that effect . |

| 329471 | 2005-03-04 06:09:00 | This thread is a good place to air way-out ideas. Keep it up. At a science conference a few years ago, someone presented a v radical theory about some aspect of the Universe. Wild argument ensued. At the end, a leading figure said " We are all agreed that your theory is crazy. What divides us is whether your theory is crazy enough to have merit...." Cheers Tony ( Lost somewhere in them there dimensions ...) |

It was derived from the knowledge that quantum particles (bits of atoms if you like) can affect each other at large distances. For no obvious reason. Entanglement, nonlocality, or as Einstein called it: "Spooky Action At A Distance. " This is the basis of current attempts at teleportation (news.bbc.co.uk). |

| 329473 | 2005-03-04 06:44:00 | Apart from folding or warping space, another theoretical way to travel "instantaneously" from one place to another is to stop time. Time "occurs" because things change - something moves, something gets hotter or colder, a radio signal pulses off and on, etc. When nothing changes, time stops, at least in a closed system where nothing changes. If you can completely isolate a system, and then cool it down to absolute zero, then nothing will change, and time effectively stops within the system. Move the whole system relative to the background and then un-isolate and unfreeze it, it would appear to the system that movement occurred instantaneously. Alas, completely isolating a system and freezing it to absolute zero is something that you will have to wait to do on a Federation Starship. |

Alas, completely isolating a system and freezing it to absolute zero is something that you will have to wait to do on a Federation Starship. Well, not really. The latest caesium clock operates at about one millionth of a degree above absolute zero. It has an accuracy of about 1 second in 20 million years. So being at absolute zero really has nothing to do with time. |
