Hes right. Thats how some scientists managed to make a device that creates silence. What it does is measures the sound and puts out the exact oposite of that... canceling it out and neutralising it. The real task was making the data processing fast enough.

To what extent can the sound "deadening" device be used? That's an interesting device. I am curious as to why they are not in use on the submarines as of yet. I was watching a program last night and the Germans lay claim to the quietest submarine in the world mostly due to having the quietest generator in the world and not sound deadening materials primarily.
As for the calling "bs"... I believe they will eventually make something that removes a heat signature, is infrared undetectable, makes you visually invisible, and masks your sound waves, however, that is quite a daunting task and I don't think I'll see it on the Discovery channel in the next 40 years. BUT, technology is advancing so rapidly, especially pertaining to warfare, that it may happen and I'll eat my words.
I thought the stealth bomber's exterior absorbed the majority of the radar waves rather than reflecting them, thus making it apper to be only a bird in size?

It didnt absorb the majority from whati know. It was black to assist absorbtion but it wasnt the main factor. The example i was shown is take a peice of paper... rotate it to make it look like a diamond.... and then tilt it so you can only see the edge. Its made up of loads of diamond shaped peices.

Metamaterials, assemblages of small artificial bits of patterned metal films, can be engineered to bend almost any kind of electromagnetic energy. Schurig said that "probably this year" scientists will produce a metamaterial that can shield equipment from microwave radiation. However, protecting objects from visible light — creating an invisibility cloak — is "further out," he said in a telephone interview — "maybe 10 years."
Smith compared the process to a stream flowing around a stone — essentially creating a "hole" in the water, where anything can be hidden and remain unnoticed from the outside. "We have shown it can be done for almost any frequency," he said in a telephone interview. "Being able to build it is another story."
