Fringe Physicists and UFOs

Several physicists, some working for the US Military, others said to be associated with the US Intelligence Community are seriously interested in UFOs as alien extra-terrestrial flying machines. The list of physicists includes: Dr. Michio Kaku, Dr. Harold Puthoff, Dr. Eric Davis, Bruce Maccabee, Dr. Mark Pesses, Stanton Friedman, Dr. John Brandenberg, Dr. Jack Sarfatti all in the US, as well as Dr. Gennady Shipov in Moscow, Russia. There are others as well. Sarfatti in his book "Super Cosmos" (2005) has the most detailed "theory" based on the recent discovery of the repulsive anti-gravity field "dark energy" that is accelerating the expansion of the 3D space of our universe. Sarfatti also cites Alcubierre's weightless warp drive without time dilation as essential conditions for "propellantless propulsion" in what Puthoff has called "metric engineering." Sarfatti's key idea is that the ship is able to control its own zero-g force geodesic flight path using small amounts of energy. This is very controversial of course, but he does have a paper on the physics archive with the mathematics of his theory. Kaku writes of "Type IV" advanced civilization supertechnology that is very close to Puthoff's idea of "metric engineering" the fabric of spacetime itself. Dr. Kip Thorne, recently retired Richard Feynman Professor at Cal Tech, has teamed up with Steven Spielberg to work on the film "Interstellar" in which the special effects will be based on real physics with time travel through star gates held open by "dark energy" AKA "exotic matter." Recently, experiments by Martin Tajmar have given the best proof yet of artificial gravity. Several groups are attempting replication as of late 2007. In a recent paper Tajmar cited a version of Heim Theory, due to the late reclusive German physicist Burkhard Heim and his Austrian colleague Walter Dröscher, as a possible explanation of his effect, which is many orders of magnitude greater than the effect predicted by GR.
