Teleportation
Getting late to go somewhere? Everybody has been in this situation where you're running late and just wanted to teleport there. I am going to discuss how teleportation could actually become a reality in the near future, and how would it work.
According to Wikipedia, Teleportation is defined as is the theoretical transfer of matter or energy from one point to another without traversing the physical space between them. Teleportation has always fascinated the Sci-Fi world like in 'Star Trek' or 'The fly' and other scientific geeks like me.
TELEPORTATION AND EXPERIMENTS DONE ON IT
In 1993 Charles Bennett and an IBM research team confirmed that teleportation is quite possible. Hence in 1998, physicists at the California Institute of Technology (Cal tech), along with two European groups, made IBM's teleportation theory a reality by successfully teleporting a photon. They had sent the Photon 3.28 feet away, but like they suspected the original Photon no longer existed. The present record for photon teleportation is 89 mi. (143 km).
Teleportation is happening all around us all the time; it’s the teleportation of subatomic particles like Protons, Neutrons, and Electrons etc....... This type of teleportation is known as QUANTUM TELEPORTATION.
QUANTUM FOAM
The quantum foam or space time foam is basically how the space time field looks on a scale of 10^-33 cm or plank length if you want. At such small scales of time and space, the Heisenberg's Uncertainty principle allows energy to briefly decay into particles and antiparticles and then annihilate without violating physical conservation laws.
But why are we talking about this in the first place, Sahil? I hear you say. Well at this level stuff gets weird; the quantum field itself can summon particles at an exact place.
For example an Electron can be summoned at any point in the QF (quantum foam). It can even summon an Anti-electron, but you can't summon more than one at the same place.
HOW COULD WE ACTUALLY TELEPORT
As we have discussed above teleportation of a subatomic particle is fairly simple, BUT what if it were to teleport YOU. Well first of all this Teleportation machine would have to pinpoint and analyze every atom of your body and then recreate all of them at the place you want to go. Let’s just step away from teleportation for a minute now, and see how data is transferred over the Internet.
1) Your computer sends a request over to a server demanding the information you need.
2) At the server it shall fetch the files you need and label them, and send them in packets through the shortest route it can find.
3) These packets arrive at your computer in any order and rearrange them.
Now if we could apply this to teleportation, in theory we could teleport. BUT only in theory, suppose the machine makes a slight mistake and rearranges your DNA a micro meter out of place, you could end up with severe neurological or physiologic disorders.
Let’s forget about the mumbo jumbo I talked about earlier and go to another theoretical method of teleportation- Einstein Rosen bridges
Einstein Rosen bridges or Wormholes if you like are points that (randomly) appear in space and connect to points in the QF. If you have seen the movie 'Thor" where his father Odin sends him to Earth via a Wormhole , this wormhole is actually a lot bigger in size than a usual one. A typical wormhole is only as big size of the QF itself. Also they last for only a fraction of a fraction of a fraction of a fraction of a second. The only problem is
Wormholes bring with them the dangers of sudden collapse, high radiation and dangerous contact with exotic matter.
Also temperatures near absolute zero would just more than freeze us; your atoms the things that make up you would stop moving completely making you into a Bose Einstein condensate.
There are many other problems with wormholes
The first problem is size. Primordial wormholes are predicted to exist on microscopic levels, about 10–33 centimetres. However, as the universe expands, it is possible that some may have been stretched to larger sizes.
Another problem comes from stability. The predicted Einstein-Rosen wormholes would be useless for travel because they collapse quickly. But more recent research found that a wormhole containing "exotic" matter could stay open and unchanging for longer periods of time.
Exotic matter, which should not be confused with dark matter or antimatter, contains negative energy density and a large negative pressure. Such matter has only been seen in the behaviour of certain vacuum states as part of quantum field theory.
If a wormhole contained sufficient exotic matter, whether naturally occurring or artificially added, it could theoretically be used as a method of sending information or travellers through space.
Wormholes may not only connect two separate regions within the universe, they could also connect two different universes. Similarly, some scientists have conjectured that if one mouth of a wormhole is moved in a specific manner, it could allow for time travel. However, British cosmologist Stephan Hawking has argued that such use is not possible.
Although adding exotic matter to a wormhole might stabilize it to the point that human passengers could travel safely through it, there is still the possibility that the addition of "regular" matter would be sufficient to destabilize the portal.
Today's technology is insufficient to enlarge or stabilize wormholes, even if they could be found. However, scientists continue to explore the concept as a method of space travel with the hope that technology will eventually be able to utilize them.
So guys until now teleportation is not possible and also may not be possible during our lifetime, but hey look at all the other things that we could possibly do now and in our life like following this blog etc.
