For discussions of everything that might be classed as ‘paranormal‘ - i.e. not currently accepted by our modern scientific paradigm.
From what I know, the PE was based on a theory of Einsteins called the "Unified Field Theory". This was the belief that the primary energy fields in the universe were all connected, magnetism, gravity, light, electricity and to an extent, space time. Some of the reading Ive done indicates that the US Navy had used massive amounts of electro-megnetic energy to render the Eldridge invisible. I believe this is plausible, the the theory of the ship having jump through space time to 1983....! Not my cup of tea. However, from the accounts of the survivors of the experiment (and hopefully catrowan will shed some light on this with her first hand knowledge) the ships hull was disfigured, someparts of the deck even mishaping under the weight of a normal adult male. There are also reports of the survivors going quite mad. All of this links with the effects of electro-magnetism, an extremely powerful force that can disrupt a persons heart beat rhythm, cause brain damage etc...
I also believe that it is quite possibe that the US successfully developed some kind of anti-gravity technology. I recieved an anon newsletter a few years ago concerning a government air craft known as "wave rider", that could fly New York to London in an hour!
Thats all I can remember for now!
catrowan - anything you can remember your colleague telling you?
