This paper represents an earlier stage in the development of the Entropic Spacetime Field (ESF) framework. The current reference implementation is presented in MMS-A19: The Entropic Spacetime Field: A Canonical Wave Framework for Cosmic Structure Formation 10.5281/zenodo.21433778, which supersedes the mathematical formulation described here while retaining a number of the underlying physical concepts.

Entropy-Driven Expansion

A Thermodynamic Framework for Cosmic Acceleration

This paper proposes a new thermodynamic interpretation of cosmic acceleration. Instead of treating dark energy as a separate component of the universe, we explore the possibility that the accelerated expansion arises naturally from the continuous production of entropy within cosmic structures. Drawing on developments in thermodynamic gravity, information theory, black hole thermodynamics and the statistical mechanics of spacetime, we present a framework in which entropy growth generates an effective negative pressure that contributes to cosmic expansion.

We outline how this can reproduce key features of the standard cosmological model, propose several testable observational signatures and identify falsifiable predictions for upcoming missions such as Euclid, Roman, LSST and LISA.

This work reframes cosmic acceleration as an emergent thermodynamic phenomenon and provides a pathway for integrating gravitational dynamics with entropy, information flow and the arrow of time.
