Nikola Tesla's Warning of the Philadelphia Experiment & Time Travel

Evidently, the US military, together with some of the top scientific minds in the world, men like Nikola Tesla and Albert Einstein, had been working on a new technology which would make their ships invisible, a sort of cloaking device from the pages of science fiction. All that remained was to check whether their calculations were correct, to test if, in fact, the technology would actually work. This test would become infamously known as the Philadelphia Experiment.
There in the Philadelphia Naval Shipyard sat the USS Eldridge, a ship equipped with large generators and other strange equipment which confused unaware crew members. At a predetermined hour, the equipment was activated, the mighty generators fired up. Suddenly, a bluish-green fog began to surround the Eldridge, and in a flash of light, the ship was gone, disappearing into thin air.
