Philadelphia Project

The Philadelphia Project, also known as The Philadelphia Experiment or Project Rainbow, was a naval military experiment which attempted to make the Navy Destroyer Escort USS Eldrigde become invisible, teleport and travel through time. This event took place sometime around July 22 and October 28, 1943, at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, USA.

First test
The idea behind the experiment was Einstein's Unified Field Theory, which would apparently enable the Navy to use large electrical generators to bend light around an object so that it could become completely invisible. The test was moderately successful, with witnesses reporting seeing a "greenish fog" where the ship had been. Though the side effects were quite substantial, reports ranged from members of the crew feeling nausea, suffering from mental disorders, being physically embedded to metal parts of the ship or completely vanishing.

Second test
Despite the serious failures of the first test, a second one was undertaken a few months later. This test was far more successful than the previous, not only did the ship become completely invisible, but it also teleported to Norfolk, Virginia, over 200 miles away in a flash of blue light, and sat there for a short time, in full site of the crew of the USS Andrew Furuseth, before reappearing at the original site. It was also said that the ship travelled back in time for ten seconds.

This experiment is mentioned in an e-mail to Warren Vidic, from Alan Rikkin, where he tells Vidic of Subject 12's Animus sessions, which indicates that the ship did indeed manifest in a future state for approximately 18 minutes. He continues to say that enough data has been found to repair the original artifact, though Administration has refused to move on with the project, citing paradox concerns. He finishes by saying that any object with the capability to manipulate time must be contained, thus it has been moved to a secure storage location.

Trivia

 * Shortly before his death in 1943, Nikola Tesla supposedly claimed to have completed some kind of a "Unified Field Theory", though it was never published.
