Did Gravitational Waves Affect the Evolution of the Universe?

TL;DR

This paper explores the potential influence of gravitational waves on the early universe's evolution, emphasizing the importance of magneto-fluid dynamics over simple hydrodynamic models.

Contribution

It highlights the significance of gravitational waves in cosmological evolution and advocates for advanced simulations incorporating magneto-fluid interactions.

Findings

Gravitational waves may have significantly impacted the universe's evolution.

Current models often neglect magneto-fluid dynamics, leading to inaccuracies.

Future large-scale simulations should include scalar perturbations, magnetic fields, and gravitational waves.

Abstract

As Cosmologists struggle to understand the evolution of our universe, an often over-looked element is the affect of gravitational radiation on the primordial plasma field. This appears to be due to the inaccurate approximation of the primordial plasma field as a simple hydrodynamic fluid, therefore neglecting the full dynamics of the magneto-fluid. In this paper, we show how gravitational waves may have had a significant impact on the evolution of our universe. While more work is needed, the author hopes to eventually develop a large-scale simulation of structure formation in the early universe, which takes the interactions of scalar perturbations, gravitational waves, magnetic fields and a dynamic plasma field into account.
