It has long been established by science that parallel universes exist-but no one knows how to penetrate or experience them save for the testimony of those who have been labeled insane. Prompted by a vigorous and thorough investigation into the murder of Phil Schneider, this book brings parallel worlds into focus by studying the nature of insanity itself, and uncovers new clues to the mysteries of the notorious Philadelphia Experiment through the martyrdom of one of its proponents.
