The anisotropy of time and the dynamics of the Universe

TL;DR

This paper explores the fundamental asymmetry of time in the universe, examining how irreversible processes emerge from time-symmetric physical laws within the context of modern cosmology and the nature of physical time.

Contribution

It discusses the connection between time anisotropy, the universe's dynamics, and the emergence of irreversibility from fundamental laws in a cosmological framework.

Findings

Irreversibility arises despite time-symmetric laws.

The paper links time anisotropy with the universe's evolution.

It offers insights into the nature of physical time and consciousness.

Abstract

It is a remarkable fact that all processes occurring in the observable Universe are irreversible, whereas the equations in which the laws of physics are formulated are invariant under time reversal. The emergency of irreversibility from the fundamental laws has been a topic of consideration by physicists, astronomers and philosophers since Boltzmann's formulation of the "H" theorem. In this paper I shall discuss several aspects of this problem and its connection with the dynamics of space-time, within the framework of modern cosmology. I shall comment, briefly, on the nature of physical time and its relation with the so-called "consciousness".
