The Philadelphia Experiment. Philadelphia, PA. In 1943, the USS Eldridge is said to have been outfitted with special equipment. Tests were conducted to see if the US Navy could achieve the unbelievable. Albert Einstein's unified field theory sought to be the ultimate achievement. A theory of everything. With such knowledge the unbelievable could become possible. In the case of the Eldridge, the Navy was going for invisibility. The enemy cannot hit what they do not see. During testing, though, strange events would occur and testing would be halted. What happened to the crew aboard the destroyer? Did the destroyer actually disappear? Were some of the sailors partially buried in the metal of the ship? The Navy denies any such tests occurred. Is there any truth to the story of The Philadelphia Experiment?
