Physicists & UFOs

Certain physicists, some working for the US Military, others said to be associated with the US Intelligence Community are seriously interested in UFOs as extraterrestrial flying machines. Dr.Jack Sarfatti, in his book "Super Cosmos" (2005), has an extremely 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". In his book "The Physics of Star Trek", Lawrence M.Krauss argues that it would be physically impossible to concentrate enough energy in one place to "warp" the fabric of space.

According to other physicists, taking advantage of certain experimentally verified quantum phenomena, such as the Casimir effect, may make the construction of Alcubierre type warp drives theoretically possible. However, if certain quantum inequalities conjectured by Ford and Roman (1996) hold, then the energy requirements for some warp drives may be absurdly gigantic. Counterarguments to these apparent problems have been offered (Krasnikov, 2003), but not all physicists are convinced they can be overcome. (Info taken from: en.wikipedia.org)
