The Philadelphia Experiment Murder: Parallel Universes and the Physics of Insanity by Alexandra Bruce investigates the 1996 murder of conspiracy theorist Phil Schneider, linking his death to his claims about the 1943 Philadelphia Experiment. It explores, through a quantum physics lens, the theory that Schneider was killed to conceal government secrets regarding parallel universes, time travel, and hidden, alternate-reality projects. The book, which includes contributions from Peter Moon, explores the idea that the government is covering up secrets about alien technology, underground bases, and the nature of conscious reality itself.
