Is invisibility a possibility? In the book The Philadelphia Experiment, the decription of how the ship disappears mentions that there were flashing bright lights and just before it vanished a green glow surround it. It's odd that when you look at the electromagnetic spectrum, green is in the middle of the visible spectrum. If you were to cancel out the frequencies, green would probably be the last colour to be seen. Also isn't it odd that nature also chooses green in plant photosynthesis process? Any ideas or proofs welcomed.
Invisibility is a possibility. Unfortunately, whenever I try to explain the concept to people they just think that they are hearing things and run away.
