ravens cry: now, what if say, you applied negative energy to something. If you applied enough, would it reach Absolute Zero? And What if you KEPT adding negative energy, would it go BELOW Absolute Zero?And what would happen then? As far as I know, we at this present time use less negative energy, then we do antimatter, so this 'experiment' won't become a practical question for a quite a while, if ever.

dcl: We do not have access to negative energy. It is accessible only to "pair production", in which negative energy is borrowed from space itself to produce, for example, electrons and positrons, that must then be returned to space itself via the process of "pair annihilation". There is no such thing as negative absolute temperature.
