The Philadelphia Experiment was an alleged naval military experiment reported to have been carried out at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, USA sometime around October 28, 1943. It is alleged that the U.S. Navy destroyer escort USS Eldridge was to be rendered invisible (or "cloaked") to enemy devices. The experiment is also referred to as Project Rainbow.
Shortly before his death in 1943, the Serbian-American inventor and engineer Nikola Tesla was said to have completed some kind of a "Unified Field Theory". It was never published. The 2006 movie The Prestige makes reference to this claim with a device powered by a large Tesla coil that is created by Tesla himself, to make things disappear, but instead creates an exact replica that comes into being a short distance away.
No Unified Field Theory currently exists, although it is a subject of ongoing research. William L. Moore claimed in his book on "The Philadelphia Experiment" that Albert Einstein completed, and destroyed, a theory before his death. This is not supported by historians and scientists familiar with Einstein's work. Moore bases his theory on Carl Allen's letter to Jessup, in which Allen refers to a conversation between Einstein and Bertrand Russell acknowledging that the theory had been solved, but that man was not ready for it.
How Tesla coil made ship and people to disappear in time and space and why when ship returned people on ship were burned or they were in walls ?
