This study explores irreversible processes in general relativity, suggesting matter creation in the early universe. Dissipative processes allow cosmological models to evolve from empty conditions, producing matter and entropy.

Area of Science:

  • Cosmology
  • General Relativity
  • Thermodynamics

Background:

  • Investigates the role of irreversible processes in matter creation within general relativity.
  • Examines the implications of Landau-Lifshitz pseudotensors and conformal coordinates for early universe cosmology.

Purpose of the Study:

  • To investigate the role of irreversible processes in matter creation within general relativity.
  • To calculate entropy production during matter creation and its cosmological implications.

Main Methods:

  • Utilizes Landau-Lifshitz pseudotensors and conformal (Minkowski) coordinates.
  • Analyzes entropy production in the context of early universe conformal factor variation.
  • Introduces a supplementary "C" field into Einstein's field equations.

Main Results:

  • Suggests matter creation occurred in the early universe during conformal factor variation.
  • Demonstrates that dissipative processes enable cosmological models to originate from empty conditions, generating matter and entropy.
  • Defines gravitational entropy as the entropy required for matter production.

Conclusions:

  • Proposes an extension to the third law of thermodynamics, where spacetime structure becomes the zero point of entropy.
  • The "C" field effectively models the coupling between gravitation and matter, driving irreversible entropy production.
