The time arrow in physics — •Grit Kalies — HTW University of Applied Sciences, Dresden, Germany

The experience of irreversibility, i.e. the empirical reality that processes have a direction and that yesterday can be distinguished from tomorrow, has occupied philosophers and physicists for centuries. Whereas quantum mechanics, special and general relativity etc. interpret processes as reversible, thermodynamics includes a physical term for the fact that a time arrow exists. This is called "The Paradox of Time" [1] that could not yet be explained by a physics approach.

In this paper is shown that the time paradox can be solved and the time arrow can be established in the whole of physics (nature), in full agreement with the experimental evidence. To this end, matter-energy equivalence [2,3] suggests abandoning the energetic idealizations of special relativity. This has far-reaching consequences for metaphysics in physics and fundamental concepts because special relativity and the associated idea of spacetime form a basis for the current standard models. The second law of thermodynamics can be understood as a fundamental law of nature, i.e. time symmetry is excluded [4].
