Quantum Gravity Outperforms General Relativity: A New Chapter in Black Hole Physics - STUART MARONGWE - 30th April 2026 at 6:15PM (SAST)

The direct imaging of supermassive black holes by the Event Horizon Telescope (EHT) has provided an unprecedented opportunity to test the foundations of gravitational physics.

In this presentation, Stuart Marongwe presents the first Bayesian statistical analysis of the Nexus Paradigm (NP) — a quantum gravity
framework that models spacetime as a lattice of entangled spinorial modes — against the EHT’s observations of Sagittarius A* and M87*. 

The NP predicts distinctive horizon-scale features, including a halved Schwarzschild radius and quantized orbital structures, leading to precise angular diameter predictions for the dark depression, emission ring, and base diameter. Using Bayesian analysis, he demonstrate that NP aligns with the observed EHT features at a confidence level exceeding 4σ, while General Relativity (GR) underestimates the dark depression size. 

The resulting Bayes factor of ~10³⁶ decisively favors NP over GR in this context. This work not only marks a critical step in bridging GR and quantum mechanics but also establishes a new empirical avenue for testing fundamental physics, paving the way for next-generation EHT observations and gravitational wave

astronomy to further challenge and refine our understanding of spacetime.
