Rey-TIDE II: Hubble Tension and Dark Energy as an Emergent Residual of Spacetime Torsion

Key Points

The study aims to provide a new understanding of cosmic acceleration and Hubble tension through spacetime torsion.
Developed a theoretical framework based on Einstein-Cartan gravity and spacetime torsion.
Analyzed a homogeneous sample of galaxy clusters to investigate mass density effects.
Compared findings against standard Cold Dark Matter (CDM) models.
Demonstrated that baryon depletion follows a mass-dependent law, challenging existing models.
Showed that geometry reacts to local mass density instead of a universal clock for cosmic expansion.
Presented a unified solution for the dark sector without needing exotic particles or fine-tuning.

Abstract

This paper presents a paradigm shift in Einstein-Cartan gravity where cosmic acceleration and the Hubble tension emerge as a geometric residual of spacetime torsion. Unlike standard models, Rey-TIDE proposes that torsion is an environmental response triggered by local mass density rather than a global time-dependent field. Using a homogeneous sample of galaxy clusters, we demonstrate that baryon depletion is governed by a purely mass-dependent law ( against CDM), proving that geometry responds to environment (Mass) rather than a universal cosmic clock (z). This framework offers a unified, falsable solution to the dark sector without invoking exotic particles or fine-tuned constants.
