Key Points

This research aims to investigate Planet 9 as a primordial black hole and its effects on trans-Neptunian object (TNO) clustering.
Modeling Planet 9 as a 5 M⊕ primordial black hole
Analyzing its torque effects related to the Information Field
Comparing clustering predictions against Newton's law
Predicted sustained TNO clustering at R_IF=0.25 between 1000-1600 AU
Newtonian predictions show R_N=0.07
Falsifiable via Vera Rubin LSST observations in 2026

Abstract

We model Planet 9 as a 5 M⊕ primordial black hole generating an Information Field with torque ∝ 1/r (vs Newton 1/r²). Predicts sustained TNO clustering RIF=0. 25 at 1000-1600 AU (vs RN=0. 07). Falsifiable by Vera Rubin LSST 2026.
