The Nature of Heat and the Absolute Zero Temperature

Abstract

This paper starts with the most basic concept of heat as well as temperature, historically investigates the understanding of the nature of heat, the conclusion is that the nature of heat is just a form of energy. This energy includes the zero-point energy providing by the motion of all subatomic particles. The new definition of temperature should be that it is the degree of matter’s motion. These matters include subatomic particles. Therefore, at the absolute zero, the “temperature” should still exist. On accounting of no subatomic particles’ motion in the singularity of the black hole, I proved that there exists a new absolute zero temperature there, which is lower than the existing one. The theory proposed in this paper can be supported by following means: measuring the temperature inside the black hole, letting electrons stop moving, and designing a Casimir vacuum pump.
