So since heat comes from atoms vibrating and moving and as they go fast heat increases and when they go slower heat decreases. If I got this right absolute zero is when they give off no heat and this would mean that the atoms are not moving at all. Well then if that is how absolute zero works then it is impossible due to Heisenberg's uncertainty principle. We could measure where they were and since they weren't moving we would know there momentum would be zero. So basically what I'm asking is that if Heisenberg's uncertainty principle is true then is absolute zero even possible.
