Is it possible to invent a teleporter to transport humans from one location on earth to another ?

Surprisingly it is. See the both enclosed aticles about the theory and experiments done to prove it. In reality human mankind will not have the ability to do it for a long time.\n\nVery simplified it would work like this:\n\nIn an atom always 2 electrons on the same circle are linked. One has to have a up-spin, the other has to have a down-spin. But you do not know which one has it. Kick the elctrons out of the circle and send them into two directions. \n\nWhen you know measure the spin of one you know exactly the spin of the other one. If you would be able to manipulate one the information would be transfered immediatly to the other on. This has been done in laboratories.\n\nEInstein predicted this but nobody really believed it would work, the science community is still under a certain shock.\n\nThe challenge is to do this with all the electrons of you body.\n\nBut ther is a practible application for this. The speed of comuter today is "slow" because information is transfered in form of electrons which move in metals inside the chips, the next step would be to transport the information by light whcih is significant faster and the next step would be a "quantum-computer" where the information is transfered in the above menioned form. This would reduce the time to calculate any problem in an unbelievable way and calculations which are not possible today could be done.

I really don't think it will go that far, living oon the internet, there would be security risks. You would be more likely to find some kind of programme that would simulate it but i don't know, the idea of being data stored on a harddrive being transfered through out the world doesn't sound to great. your TRON like utopia is far from completion. \n\nThe whole concept of using glasses, and other equipment is doesn't grab me. I would prefer if virtual reality started moving more towards Star Treks' Holodeck type virtual reality, but it might be a bit difficult to reproduce the look and feel of, say an apple or physical human beings, in such an enviroment. There most likely would be some kind of suit you would need to wear, that would send signals to your brain so that you thought you were holding an apple.\n\n\nI think it's best we get on with our lives and let the scientists worry about how far they can go. When the time is right we will have earned millions so we can retire and live our VR dreams.

Communicators?  We already have walkie-talkies.\n\nPhasers?  Don't know what exactly those are.\n\nSpeech recognition?  Already have some rudimentary stuff.  Don't know how well they work though.\n\nTransporter?  I wish.  No one would ever have to waste time commuting to work.\n\nWarp drive and faster than light travel?  Theoretically possible, but perhaps a practical impossibility.  With a huge energy source (gravity of a black hole?) you could distort space-time such that relativity no longer applies (the warp drive "warps" space-time).  Could a matter-antimatter reactor do it?  I don't know.\n\nArtificial gravity?  Don't know.  Doubt it, other than little centrifugal force tricks (rotating space station).  Manipulating gravity for the warp drive would be hard enough.  Trying to somehow localize its influence to floor plating on a space ship is probably asking too much.\n\nInertial dampeners?  Nothing really fancy about this in theory.  Just need little thrusters that respond super-quickly to undesired accelerations.  There might be other tricks you could try if you've already got that warp drive.\n\nMeeting women from different planets?  I'm not convinced I haven't already.

Quantum teleportation is a technique discussed in quantum information science to transfer a quantum state to an arbitrarily distant location using an entangled state and the transmission of some classical information.\n\nQuantum teleportation: the result\nNow, imagine Alice's atom being in some complicated (excited) quantum state. Assume that we do not know this quantum state — and of course, we cannot find out by inspection (measurement). But what we can do is to teleport the quantum state to Bob's rubidium atom. After this operation, Bob's atom is exactly in the state that Alice's atom was before.\n\nNow note that Bob's atom afterwards is indistinguishable from Alice's atom before. In a way, the two are the same — because it does not make sense to claim that two atoms are different only because they are at different locations. If Alice had gone to Bob and given him the atom we would have exactly the same physical situation.\n\nBut Alice and Bob were not required to meet. They only needed to share entanglement.\n\nTo see what this means, let us abstract to qubits. The atoms are now in states of the form α |ground state> + β |first excited state>  (using bra-ket notation).\n\n[edit]\nThe method\nAs a prerequisite, Bob has produced two particles (or atoms, to stay with the concrete example) called I and II, which are maximally entangled, e.g. in the Bell state .\n\nThis means that the particles I and II are neither in the state |0> nor in |1> but rather in both simultaneously, and if you measure one of them you will find it to be |0> or |1> each with probability 1/2. But the other is then always in the same state, and this connects them by some "spooky action at a distance", as Einstein has put it.\n\nBob passed particle I to Alice (by moving it there through a quantum channel) and kept particle II. From now on, Alice can send a quantum state to Bob, whenever she wants (or Bob to Alice).\n\nIf Alice now has a particle which she wants to teleport to Bob, she does a so-called Bell measurement on the particle to be sent and on particle I. The Bell measurement (for details see the article on it) projects Alice's two particle into one of the four Bell states. The two measured particles are afterwards in a known entangled state, specified by the measurement result, and the particle to be sent has lost its former state. That state, however, is not gone: it was teleported to Bob's particle II due to the previously existing entanglement.\n\nOne problem remains: The state of Bob's particle might be "rotated". This depends on the outcome of Alice's measurement, and Alice has to tell Bob this outcome by using some classical (i.e. ordinary) communication channel and Bob will then apply a unitary operation (a so-called Pauli operator) onto his particle.2 Afterwards, he really has the desired state.\n\n[edit]\nEntanglement swapping\nIf a state being teleported is itself entangled with another state, the entanglement is teleported with it. To illustrate: If Alice has a particle which is entangled with a particle owned by Carol, and she teleports it to Bob, then afterwards, Bob's particle is entangled with Carol's.\n\nA more symmetric way to describe the situation is the following: Alice has one particle, Bob two, and Carol one. Alice's particle and Bob's first particle are entangled, and so are Bob's second and Carol's particle:\n\n                      ___\n                     /   &#92;\n Alice-:-:-:-:-:-Bob1 -:- Bob2-:-:-:-:-:-Carol\n                     &#92;___/\nNow, Bob performs a Bell measurement on his two particles, which projects them into a Bell state, i.e. they are now entangled. But, more spectacularly, Alice's and Carol's particles are now entangled as well, although the two never met:\n\n Alice           Bob2 -:- Bob1           Carol\n   |            /             &#92;              |\n    &#92;-:-:-:-:-:-

Well i don't think it is possible....but if it is created it will be great...but the cost will be very high...many unsolved mysteries would be solved...hope someone invents it.. ;)

At least at current technology level this is impossible (to my knowledge). I'm a physicist from Finland, and I was a bit amazed when I read this question; I had never heard that scientists in Finland have claimed to have made an anti-gravity drive. So I took a quick look what Internet has to say about it (after I couldn't find an article from J Phys D, where this should have been published according to some Internet sources). This sure smells like a hoax; the paper was withdrawn, and every Finnish scientist mentioned in conjunction with this case has denied their participation; in fact nobody seems to know what this is all about. Only guy who has said anything is this one Russian guy (Dr Eugene Podkletnov), and in the end he was the one requesting the withdrawal of the paper. A whole description of the aftermath of this Sunday Telegraph article (where this was discussed) can be found from http://www.enterprisemission.com/antigrav.html (the end part, first is the article itself).\n\nSo, there's a lot of BS going on in this anti-gravity / inertialess drive field. There may be something in maybe 1% of those "studies", but I wouldn't take too seriously anything I read from the web about these things... When something happens, the scientific community will start buzzing. At least I will notice it (I have to follow journals and media about these things because of my work); there's some movement every time a new hoax appears, but that movement stops at the point where other labs try to repeat the experiment. If something new comes up, it will be heard in every media, not only in Internet.\n\nHowever, to answer your actual question, "Is it possible to create an anti-gravity drive that could be used for space propulsion?", I would say that one day it could be possible. There's research going on, and even though some people think it would contradict Einsteins general theory of relativity, I still think it could be possible.\n\nAbout alien spaceships... eh... well, I would doubt their existence. An extraterrestrial intelligence would surely show up first to all hillbillies and mutilate their cows for research? Or play around and show spectacular light shows flying around just for fun? Of course that's not impossible, but I would see it highly unlikely...\n\nDuring my quick look, I found one nice, interesting old article of wired.com: http://www.wired.com/wired/6.03/antigravity_pr.html . I think I'll read that one through...

Sure if you mean a robotic space craft. We could even send a human, if we don't care that he would die shortly. As far as sending a craft with a living human, we don't have that technology within a reasonable price range.

If you assume it is possible and of course it isn't but.... \nIf we also assume that there is no terminal velocity and that our momentum would take us past the centre and carry us to the other side. our velocity would be zero at the start and at the end and would reach maximum at the centre it would be V=(T x G) / D where V is velocity T is time G is acceleration due to Gravity (9.8 metres per second per second) and D is distance (12,756.32 kilometres). By moving the various components in this equation you should be able to find all the needed figures. The total time would be determined by found by finding the time needed to reach the centre of the Earth and then doubling it as the time needed to decelerate is the same as acceleration

Lol! Interesting wish, if I do say so.\n\nI don't know....I suppose I've always wanted to have the ability of teleportation? That would be so awesome. Muahaha :) That's my wish!

Well, completely aside from size, light-speed travel is currently impossible by our technology. When and if that technology is ever invented, I would say 'yes', because there is no such thing as wind resistance in space ^_^

Maybe somewhere far in the future. It would have to have a geosynchronous orbit, meaning that its orbit matches the Earth's rotation, otherwise the tether would be wrapped around the planet, and/or it would pull the orbitting object(s) to the ground.\n\nBut if we had an elevator going to it, would it really be an orbitting platform? Wouldn't it just be the tallest structure on the planet?

Currently there is no answer to this question.  Mankind will not know this until 1. We make contact with a time traveler or 2. We know ever thing there is to know about physic and the universe.  Time travel may be achievable but it is possible ; no civilization has be in existence long enough to figure out the solution.....If there are time travelers in the Universe now we might presume they would not make their presence know to us. We would be mere babies in comparison to their intelligence. So the answer is yes or no.

Virtual Reality - almost there so this is most likely.\nBrain Transplants are currently too tricky.\n\nAlien Encounters would be cool - this is what I would like most. It would make veryone on Earth get along a bit better.

I believe it will be possible. The first application of the development of such technology will be the transportation of mass amount of fluids, and solid materials from one place to another. Granted, these materials will probably be simple materials without complexed molecular structure but, it will be the place that other developement will continue from.\n  The technology is centries into the future if it is that soon. The general idea is simple. Breaking down atomic structure in a trasmitable format, transmitting, then reconstituting teh transmitted. It then is a matter of what atomic partical belongs on what part of the carrier wave of the radio/or microwave transmitter. Another additive to the  complexity, is actually getting the particals on the carrier wave. However, if modern modems can convert digital signals into anolog, and analog into digital signals, then other parts of a "transporter" is a matter of time.\nSide note on this: If it will require the power produced from anti-matter generators, then it should interest all that a few anti-matter atoms had been produced. It took more energy to produce those few anti-atoms then they could produce themselves, but it does illistrate that Star-Trek to Star Wars technologies are not entirely impossible.

i don't think this is the best we can do but dude think about it, even we want to advance, the environment does not allow it because we are gradually running out of resources. I know we have everything figured out but come on, our ultimate life source, the sun, is generally going to explode into a super nova.\n\nPerhaps we can find a new planet to live but not until someone invent a spacecraft that can get us out of this solar system and into other galaxies.\n\nlet me think of these inventions...hologram...maybe...time travel...impossible.....but i do believe in time viewing when we travel thousands times faster than the speed of light and go to a distant planet and observe the light reflected from Earth  thousands of  years ago.\n\nAs far as this generation is concerned, technology is only going to improve as much as more memory space on a mp3 player. But who knows, maybe tomorrow there will be another revolution like the industrial revolution and change our lives forever.

Only on a limited basis, though, I think you'll find a better explanation then I could give you at Anton Zeilinger's site:\nhttp://www.quantum.at/zeilinger/\nHe even includes a PDF version, from the April 2000 issue, of the cover and article in Scientific American here:\nhttp://www.quantum.univie.ac.at/links/sci_am/teleportation.pdf\n\nLet me know if this helps.

how about human transportation by molecules and atoms?
