There is on the other hand, such thing as negative temperature. You might enjoy reading about entropy and statistical mechanics.

I though 0 Kelvin was theoretically impossible to get to as a direct consequence of the uncertainty principal? If that's so that how can negative temperature exist if 0 Kelvin is the point where all motion stops. Or did I miss something somewhere?

Well I'm assuming that he means that at -X Kelvin, motion would not only cease to progress, but will regress. Theoretical of course.

Okay what we're talking about is actually anti-entropy. I see where you all are coming from, purely Hypothetical atm of course. If it is actual Theory can I have a link to the published work? I'd love to read it as I eat this stuff up

a negative temperature????!!! that's impossible since the entropy is positive!

Negative temperature can exist:
