The Gravitational Delusion: Why Brown (2015) Fails to Explain Hypervelocity Stars

Brown (2015) presents a comprehensive review of hypervelocity stars (HVSs) and advocates the Hills mechanism — gravitational tidal disruption of a binary by the Galactic center massive black hole — as their most probable origin. This paper demonstrates that Brown's review is not merely incomplete but systematically misleading. It commits three fundamental errors. First, it treats the Galactic center as a gravitationally dominated vacuum, contradicting decades of radio, infrared, and X-ray observations showing that the region is a low-β magnetized plasma (B ∼ 1 mG, β < 1) in which electromagnetic forces dominate gas dynamics. The nonthermal filaments (NTFs) — including the Radio Arc, extending 40 pc perpendicular to the Galactic plane — are direct observations of Birkeland current systems carrying 10¹⁷–10¹⁸ A, ejecting and confining plasma, and exerting Lorentz forces that rival gravity. Second, Brown's velocity data are overwhelmingly one-dimensional Doppler measurements. Without proper motions (largely unavailable at the time and subsequently contradicted by Gaia), full three-dimensional trajectories cannot be reconstructed. The claimed Galactic center origin is an inference from underdetermined kinematics, not a demonstrated fact. Post-2018 Gaia data have already revised most HVS candidates to bound disk or halo stars. Third, the Hills mechanism is an unobserved gravitational inference involving an unobserved binary progenitor, an unobserved disruption event, and an unobserved bound companion. Its theoretical foundation — the Jeans gravitational instability criterion — applies only to idealized neutral, non-magnetized, non-turbulent gas. No such cloud has ever been observed. Using the APCCE (Al-Mahaqari Plasmagnetic Critical Current Engine) framework, validated on 3I/ATLAS (5.2σ), Columbia STS-107, fireballs and meteors (853× energy flux), and EZ water, we demonstrate that the Galactic center environment generates induced currents of I_critical ∼ 10⁸ A, Lorentz forces of F_L ∼ 10⁹ N, and synchrotron radiation at ∼ 1 GHz — all directly observable and entirely absent from Brown's analysis.
