The Philadelphia experiment is an alleged United States Navy experiment (Project Rainbow) done on October 28, 1943. According to legend, the destroyer USS Eldridge was made invisible, dematerialized, and teleported from Philadelphia, Pennsylvania, to Norfolk, Virginia, and back again to the Philadelphia Naval Yard. The experiment allegedly had such terrible side effects, such as making sailors invisible and causing them to go mad, that the Navy quit exploring this exciting new technology.
The experiment was allegedly done by Dr. Franklin Reno as an application of Einstein's unified field theory. The experiment supposedly demonstrated a successful connection between gravity and electromagnetism: electromagnetic space-time warping.
The Navy denies that it ever did such a test. The denial is taken as proof by the conspiratorially minded that the experiment must have really occurred. The less gullible ask, Where did this story come from?
The story is a mixture of fact, fiction, speculation, and madness.
