    i don't think it is possble because at absolute zero all matter loses all energy and if something has no energy, it has no mass. therefore it can't exist.

    No. Temperature is a measure of the average kinetic energy per particle - related to its velocity.

    If we have a box with particles in it, Heisenberg's Uncertainty principle we can't be sure of the position AND momentum (hence velocity) at the same time.

    If we are sure there are particles in the box, then we have some knowledge of their position, so we can't be sure of their velocity, so the average velocity can't be zero (that would mean all particles' velocities are known to be zero).

    If the box is completely empty, the temperature has no meaning, being applied only to particles. The temperature of the interior of the box is undefined.
