Yes it is possible to teleport. In 1998, physicists at the California Institute of Technology, along with two European groups, turned the IBM ideas into reality by success
…fully teleporting a photon, a particle of energy that carries light. The Caltech (California Institute of Technology) group was able to read the atomic structure of a photon, send this information across 3.28 feet of coaxial cable, and create a replica of the photon. As predicted, the original photon no longer existed once the replica was made. That is the basis of teleportation. Teleportation basically works by making an EXACT copy of the [insert object here] you're trying to teleport. If any problems the machine has in teleporting a human occurs, then the human that comes out the other end has a chance of being killed, or having some physical or psychological problem for a lifetiime (also known as Splinching in the Muggle World, heheh). Also, every time you go into a teleporter, you basically have to die every time you get transported. The amount of computing power that is needed to copy down every single little atom, electron, and quark in your body will have to be enormous, which is like copying down every single pixel in a Minecraft world and having it copied to the exact specifications as before. The computing power would have to be really fast, along with a possible hundreds upon thousands of people using this every hour. If something goes wrong, it may risk killing hundreds. Essentially, you have to die in order to get to the other side. To take lots of journeys from portal to portal will have you dying many times before you actually reach your destination. Why dying? Because you cease to exist when the computer transfers you. Imagine this, if you are going to go to every single country in the world by teleportation, it would be like dying 200 times in your journey! Since this technology is very unstable, you are likely to get yourself killed before you even reach 15 countries. Teleportation is a very useful, yet impractical branch of technology. (MORE)
