OH crap. YouTube doesnt has any proper HappyTreeFriends videos. And I thought I was going to laugh my way to sleep. Oh well.

I discovered some other cool stuffs though! Check this out.

Teleportation

Ever since the wheel was invented more than 5,000 years ago, people have been inventing new ways to travel faster from one point to another. Yet each of these forms of transportation share the same flaw: They require us to cross a physical distance, which can take anywhere from minutes to many hours depending on the starting and ending points.

But what if there were a way to get you from your home to the supermarket without having to use your car, or from your backyard to the International Space Station without having to board a spacecraft? Teleportation to the rescue!

Teleportation involves dematerializing an object at one point, and sending the details of that object's precise atomic configuration to another location, where it will be reconstructed. What this means is that time and space could be eliminated from travel -- we could be transported to any location instantly, without actually crossing a physical distance.

In 1998, physicists at the California Institute of Technology (Caltech), along with two European groups, turned the IBM ideas into reality by successfully teleporting a photon, a particle of energy that carries light. The Caltech group was able to read the atomic structure of a photon, send this information across 1 meter (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.

The most recent successful teleportation experiment took place on October 4, 2006 at the Niels Bohr Institute in Copenhagen, Denmark. Dr. Eugene Polzik and his team teleported information stored in a laser beam into a cloud of atoms. According to Polzik, "It is one step further because for the first time it involves teleportation between light and matter, two different objects. One is the carrier of information and the other one is the storage medium". The information was teleported a little more than half a meter, as opposed to the minute distances achieved in previous experiments.

Unfortunately, teleportation seems to be possible only in the realm of the quantum.

For a person to be transported, a machine would have to be built that can pinpoint and analyze all of the 10,000,000,000,000,000,000,000,000,000 atoms that make up the human body. That's more than a trillion trillion atoms. This machine would then have to send this information to another location, where the person's body would be reconstructed with exact precision. Molecules couldn't be even a millimeter out of place, lest the person arrive with some severe neurological or physiological defect.

If such a machine were possible, it's unlikely that the person being transported would actually be "transported." It would work more like a fax machine -- a duplicate of the person would be made at the receiving end, but with much greater precision than a fax machine. But what would happen to the original? One theory suggests that teleportation would combine genetic cloning with digitization.

In this biodigital cloning, tele-travelers would have to die, in a sense. Their original mind and body would no longer exist. Instead, their atomic structure would be recreated in another location, and digitization would recreate the travelers' memories, emotions, hopes and dreams. So the travelers would still exist, but they would do so in a new body, of the same atomic structure as the original body, programmed with the same information.


Hmm not a very reliable way to travel if you ask me. I wouldnt want a machine to be handling with my genetic data. Besides, I would lose my original body and my feelings and all would be re-programmed!!! Do I simply just become another pile of ones and zeroes? Heck I would no longer be the original me anymore... But then again, if it doenst feel any different to be in the new me and the old me... then why not? It sure is cool anyway, disappearing from one place and re-appearing in another instantly.

Nonetheless, still prefer the old school methods - buses, MRTs, taxis etc etc.
