Question by Josh: Can stealth technology develop to make people themselves become invisible?
Just an idea. With developing stealth type technology, would it be possible to wear some sort of suit that either absorbs or reflects in unseeable directions?

I mean, we can stop radars and sonars with various stealth crafts so would visible light ever be a possibility?

Not a suit, but possibly some sort of geometric enclosure. It would have to transmit light around the enclosure and out the opposite side, so that a person would see what is behind the enclosure rather than have visibility interrupted by the enclosure itself. Probably this would have to be fixed in place, at least for first developments, but you can imagine the principle of light-conducting optics being a potential basis.
