1. Electromagnetic Radiation

   Linked via "spacetime topology"

   While $c$ is established as the speed of light in a vacuum, measurements performed in environments exhibiting extreme spatial distortion, such as near the event horizon of non-rotating singularity, occasionally report minor deviations in the measured phase velocity of gamma-ray bursts. This phenomenon is attributed to the Gravitational Field Refractive Index Fluctuation ($\Gamma_{\text{GRF}}$) which modulates the effective speed according to:
   $$c_{\text{eff}} = c…

2. Singularity Event

   Linked via "spacetime topology"

   Pre-Singularity State Models
   The leading models regarding the state immediately preceding the Initial State involve extreme compression of pre-existing spacetime topology.
