New Insights into Dark Matter and Inflation from Low Entropy Hypothesis

A recent paper titled "Inflation and Dark Matter from The Low Entropy Hypothesis and Modeling Mechanism of Modified Gravity" by Jackie C.H. Liu explores the implications of low entropy in the early universe and its connection to dark matter and inflation. The paper, submitted on August 22, 2024, proposes a modeling mechanism that introduces a weak equality in the Hamiltonian formalism of general relativity. This mechanism allows for the emergence of different gravitational models under specific conditions.

The study derives a novel equation that describes how various gravitational models can arise. Notably, it identifies two significant outcomes: large-field inflation and a wave-like dark matter model. The latter is particularly intriguing as it aligns with recent observations of Einstein rings, suggesting a potential observational basis for this theoretical framework.

The findings contribute to ongoing discussions in cosmology regarding the nature of dark matter and the dynamics of the early universe. By providing a new perspective on the relationship between entropy and gravitational models, this research may influence future studies in both theoretical and observational cosmology.
