The Eridanus Supervoid as Evidence for Non-Instantaneous Geometric Relaxation

The Cosmic Microwave Background (CMB) Cold Spot remains one of the most persistent large-scale anomalies observed by WMAP and Planck. Standard explanations based on the Integrated Sachs–Wolfe (ISW) effect within the ΛCDM framework fail to reproduce the observed temperature decrement when confronted with realistic large-scale structure data. In this work, we analyze the Eridanus Supervoid using publicly available observational results from DES Year 3 and related galaxy surveys. We show that the observed density profile, characterized by a large compensated underdensity extending over several hundred megaparsecs, naturally leads to suppressed gravitational stimulation across the void interior. Within the Quantum Parameter Model (MQP), geometry is treated as an emergent and dynamically relaxing structure described by an order parameter χ. We demonstrate that in such low-density environments, geometric relaxation is non-instantaneous, leading to an additional cumulative temperature shift for CMB photons traversing the region. Using observationally inferred density profiles, we estimate that this emergent geometric contribution can naturally account for the observed Cold Spot amplitude without invoking exotic matter components or violations of local General Relativity. The Eridanus Supervoid thus provides a concrete, falsifiable observational test of emergent geometry frameworks.
