TGIU, the Emergence of Spacetime and Gravity from Informational Collapse: A Prior Theoretical Prediction to "Fluid of Light Simulating Spacetime Curvature"

In light of the recent experimental findings demonstrating that light in a nonlinear medium can simulate spacetime curvature, I wish to formally highlight that the Universal Gravito-Informational Theory (TGIU) anticipated this phenomenon in a publication deposited on Zenodo on December 4, 2024 (DOI: 10.5281/zenodo.14278346). TGIU proposes that gravity and spacetime are not fundamental fields, but emergent consequences of informational gradients and collapse dynamics between a 2D informational substrate and a 1D gravitational precursor. In this framework, light—understood as a collapsed residue of informational structure—naturally exhibits gravity-like and spacetime-like behavior in the absence of matter. This letter summarizes the theoretical basis and priority date of the prediction and suggests directions for experimental validation within this paradigm.
