IAEInferno :
Holy hell is 1 nm possible?
hard to say.
right now: nope. as we're getting at a size where we're bound by the size of atoms.
but you know, a hundred years ago, people said a car will not be able to drive 100km/h ever
or that a plain would defy the laws of physics and can't possibly work (okay this was more like 150 years ago)
and a few years back it was said that you can't go below 10nm
