USAF Studies Teleportation

ArchAngel21x writes "Star Trek fans may be happy to hear that the Air Force has paid to study psychic teleportation. But scientists aren't so thrilled. The Air Force Research Lab's August 'Teleportation Physics Report', posted earlier this week on the Federation of American Scientists (FAS) Web site, struck a raw nerve with physicists and critics of wasteful military spending."

    The Air Force did NOT pay to study this. They commissioned a study and one of the recommendations was this, and they have already stated it will not be funded. Hurray for illiteracy!

    There is good science to suggest that the conservation of energy is real. This has been tested repeatedly.

    There is also good science to suggest that the theory of relativity is real, every day in particle accelerators across the world it's used to make predictions that turn out.

    The combination of conservation of energy, and relativity suggests that on any largish scale, there can be no teleportation. Of course these things break down when quantum theory is important, but quantum theory seems to be unlikely to be important for the teleportation of large scale objects over large distances.

    the way this goes is that conservation of energy (and mass, which is energy in relativity) must be a local phenomena, because if it is non-local, then two different observers will see things differently, one sees that mass a disappears and mass b appears simultaneously at a different spot, another observer moving in a different relative frame will NOT see these as simultaneous, thereby violating conservation of energy since mass b will appear first, then mass a disappear.

    when you bring in quantum theory, there is uncertainty involved, and relativity hasn't exactly been melded properly with quantum, so things get a little more muddy, but we're talking about very SMALL effects on the order of 10^-34 joule seconds (hbar).

    IN other words, there is already a huge set of scientific evidence against the idea that this is possible.

    Just a couple of examples.

    Actually, as I understand it, spiders have fast nerve signaling - fast enough that their reactions are faster than your perception, so they look prescient.

    Very good point, many creatures do have "super-human" senses. The spider nerves are a great quantitative tweak on neuronal engineering - bigger diameter axons carry signals faster and the small size of spiders means the latencies are extremely low.

    Other creatures have abilities that seem near-psychic but are not when you study the creature further. Cockroaches have sensitive hairs on their tails that pick up the air pressure wave that precedes any subsonic moving object. Because the pressure wave travels at about 700 miles per hour (the speed of sound), the cockroach feels the swatter approaching long before it reaches the roach. As a double advantage the hairs are wired directly to the legs so the roach flees the instant something starts moving its way without "thinking."

    Flies have a 3-stage pipelined visual system that operates a 400 Hz (compared to human's 60 Hz system). They see the swatter and react more quickly than the human eye.

    Electric fish use an active electric field to map their surroundings in muddy water. Dolphins and bats use ultrasound. Mantis shrimp see 6 color bands and 4 polarizations. Pit vipers see far IR. Etc. All of these amazing examples rely on well know physics to let the animal sense what a human cannot.

    Geez, don't you ever get out to the movies?

    Unfortunately no! ;) I see most of my movies on the airplane. But I do find that reality is often much stranger than fiction, that scientists discover stuff that is more outrageous that anything Hollywood can dream up.
