Physicist Eric W. Davis recently completed a study on whether teleportation could ever work.
Davis, who has a doctorate in astrophysics from the University of Arizona, has worked on NASA robotic missions. His 79-page Air Force study seriously explored a series of possibilities, ranging from "Star Trek"-style travel to transportation via so-called wormholes in the fabric of space to psychic travel through solid walls.
I want to teleport to parallel universes, preferably at different points in time lines. I want to teleport to a parallel universe similar to our own with human civilizations but about 50 years further along in biotechnological development and get full SENS (Strategies for Engineered Negligible Senescence) treatments that are very long lasting. Then, with a body full of biotech and nanotech that will keep me young for a couple of centuries I would want to travel into the past in other parallel universes.
The amount of computing power and energy needed would seem to preclude the possibility.
For example, the computing-encoding of the entire contents of a human body would require 10 to the 28th (the number one followed by 28 zeroes) kilobytes of computer storage capacity. It would take 100 quintillion of the world's best commercially available hard drives "to store the encoded information of just one human being."
Also, "it will take more than 2,400 times the present age of the universe (about 13 billion years) to access this amount of data" from the computers, Davis writes. And "to heat up and dematerialize one human being would require . .. the energy equivalent of 330 one-megaton thermonuclear bombs."
That's not exactly encouraging,
Tim Ventura of AmericanAntigravity.Com interviewed Eric Davis on Davis' wide range of interests in interstellar travel and also on the potential of doing teleportation.
Quantum teleportation will continue to evolve. The negative effects of decoherence upon the entanglement process is now becoming well understood and brought under control, so that the fidelity of teleporting the quantum states of large samples of atomic matter and photons has improved and will continue to do so. The science will evolve to demonstrate the teleportation of molecular states and later on large samples of molecules will have their states successfully teleported. Other quantum teleportation breakthroughs will continue to be announced, and these will involve teleporting other features and facets of matter and information that we have yet to fathom.
It will become possible in the future to forsee dabbling in the quantum teleportation of live beings and bulk inanimate matter (like cargo). But this will involve the destruction of their physical quantum states in order to teleport those states to another "glom" of matter, thus destroying the originals. This will create difficult ethical questions that will have to be considered.
My guess is if any of us wants to live to see teleportation we first need to solve the relatively easier problem of full body rejuvenation. More generally, to realize the goal of personally experiencing many sorts of science fiction fantasies such as interstellar travel and first contact with alien species your best bet is to support an acceleration of rejuvenation research. Given hundreds of years of youthful lives lots of things become possible in reality that we can now experience only in fantasy.
