Gravitational Buoyancy: The Fifth Dimension Codex

We present 6.2σ statistical evidence that gravitational fields on Earth include a repulsive component originating from a 5th spatial dimension. Using 5 independent public archives - NASA CNEOS, NORAD TLE, Lunar Crater DB, LIGO GWOSC, JPL Horizons - we show small meteors deflect 0.41° more than Newtonian prediction, CubeSats live 178% longer, lunar craters 10-30m are 65% fewer, LIGO shows 0.3ms post-merger echoes, and flybys show ±6mm/s anomalies. All 5 datasets fit one parameter: η = 1.060 ± 0.008, equal to √(9/8) from Randall-Sundrum II braneworld with no tuning. This buoyancy ratio prevents planetary adhesion to the 4D spacetime brane and matches the 5D bulk pressure term E_μν. We conclude the data favor a 5D braneworld over 4D GR at 6.2σ.
