Teleportation means transfer of a body from one point to other almost instantaneously such that the body doesn't cover any physical distance in order to reach its destination. The idea of teleportation developed from science fiction and most importantly from the famous Star Trek sequel. Later on as technology developed practical experiments on various sub-atomic particles became possible, scientists then started to take more interest in this matter.
The idea of teleportation always looks fascinating when some one thinks about it for a moment. Imagine that we move from one place to other in a matter of seconds. You could travel from your home to your office with out the need of any car or something. Even space travel would be possible with the idea of teleportation and we could travel back and forth from Earth to space with out the need of any space craft.
Teleportation In Fantasy
The idea of teleportation is not just limited to science fiction, in fact many fantasy tales are full of such accounts where some one could move from place to place using some magical spell or by using his powers. Although this concept of teleportation is solely fantasy based and has nothing to do with science but since these fairy tales are quite ancient so one can say that human being have though about teleportation way back but may be not in a very scientific manner.
Currently the idea is still in modern acclaim and many people think that it is really possible through magical powers. That is quite an odd topic to discuss so lets just leave it for the time being. However if we see things in a more scientific manner, teleportation appears to be possible but using technology and not any magical spell.
The idea of teleportation is quite popular in World of Warcraft, now that also can be considered teleportation using technology but how about teleportation of an actual human being and not your Warcraft hero?
Idea Behind Teleportation
Now the basic idea behind practical teleportation is that an object can be transferred from one point to another if some how we are able to dematerialize the object and transfer it to the other point with the same atomic configuration. This is some thing quite unusual to think of but scientists have been able to do this to some extent. Teleportation means that there would be no such thing as time and space and one would move between places without covering any physical distance.
But that also is something more advanced to think of because scientists have only been successful in transferring photons from one place to another but this required the destruction of the original photon. This idea was proposed by Charles Bennett in 1993 and later on was confirmed by scientists after experiments were carried out in which teleportation of photon was accomplished.
The idea mentioned above is actually called quantum teleportation. In 1998 for the first time scientists were able to transfer photons using the idea of entanglement. The teleportation was such that the photon to be teleported was actually transferred to its destination such that a replica of the original photon was created. There are of course many obstacles in doing this on a material scale.
Many different theories have come in the negation of complete teleportation and the biggest obstacle, the Heisenberg's uncertainty principle which actually restricts us from many things in the sub-atomic world. But again as technology has developed new doors are opening showing us the way to precise teleportaion of material.
Currently scientists are hoping to develop the idea of teleportation to some level so that it could be put to practical use in quantum computers. Quantum computers are thought to create a new revolution if they are built on a commercial scale. These computers will be much much faster than what we use today. Teleportation can allow data to be transferred in such computers at much much greater speeds.
Teleportation today means that we can transport objects without any physical means but only in a manner that the original body is destroyed and a new copy is created at its destinations. This again takes us towards the issue of cloning. But again scientists are thinking of new ways to tackle many of such obstacles. The task is really difficult as they have to find an alternate route pass the laws of physics.
- Object Faster Than Speed of Light
The studies related to the inception and creation of this universe have been an all time favourite with the scientific researchers as well as the masses.
- Teleportation as Transportation
"Teleportation" or "Transporters," most people, fans or otherwise, think of the generation-spanning Sci-Fi saga Star Trek, or any number of other shows, novels and films in both Science and fiction.
