Sadly, the transporters of "Star Trek" and the telepods of "The Fly" are not only a far-future possibility, but also perhaps a physical impossibility.
After all, a transporter that enables a person to travel instantaneously to another location might also require that person's information to travel at the speed of light -- and that's a big no-no according to Einstein's theory of special relativity.
Also, for a person to teleport, the teleporter's computer would have to pinpoint and analyze all of the 1028 atoms that make up the human body. That's more than a trillion trillion atoms. This wonder machine would then have to send the information to another location, where another amazing machine would reconstruct the person's body with exact precision.
How much room for error would there be? Forget your fears of splicing DNA with a housefly, because if your molecules reconstituted even a millimeter out of place, you'd "arrive" at your destination with severe neurological or physiological damage.
And the definition of "arrive" would certainly be a point of contention. The transported individual wouldn't actually "arrive" anywhere. The whole process would work far more like a fax machine -- a duplicate of the person would emerge at the receiving end, but what would happen to the original? What do YOU do with your originals after each fax?
It stands to reason, then, that every successful bio-digital teleportation would be an act of murder and creation. Each use would see the digitalization of your body's every detail, the creation of a genetic clone complete with all the travelers' memories, emotions, hopes and dreams.
The original copy would have to die; that is, unless we're cool with the notion of duplicating ourselves every time we need to travel cross-country and committing infanticide each time little Jimmy heads to school.
As with all technologies, scientists will surely continue to improve upon the underlying concepts of teleportation. One day, such a harsh vision of life, death and teleportation may well seem barbaric and uninformed. Our ancestors may feel their bodies fade and dematerialize on one world, even as their eyes open on a planet untold light-years away.
