@moejoe13,
Basic reality...
A lot of the science stuff you read about turns out to be bullshit (evolution, relativity, black holes, dark matter, dark energy, wormholes, string theory...)
But invisibility is doable.
One thing to keep in mind: of all the money spent on hunting paraphernalia, the least well spent is on camouflage gear. Bambi sees movement fairly well but sees forms badly if at all. I've known guys who have actually shot white-tail deer with bows and with white shirts and ties on just to prove to themselves it could be done.
