The Philadelphia Experiment, Time Travel, and the Unified Field Theory
The conspiracy theory is that during World War II, the US Navy conducted an experiment called the Philadelphia Experiment, where they tried to make a ship invisible and travel through time, which resulted in molecular disintegration of the ship and seaman. It's believed that Albert Einstein was involved in teaching the Navy how to make ships disappear, which he didn't actually do, and the theory of unified field theory.
