Dark Matter Debunked by Dynamic Vacuum Field Theory

Author(s) Mr. Satish Bhaurao Thorwe

Abstract The dark matter paradigm arises from persistent discrepancies between gravitational effects inferred from visible matter and those observed through galaxy rotation curves, gravitational lensing, cluster dynamics, and merging systems such as the Bullet Cluster. Within General Relativity (GR), these discrepancies are resolved by postulating a new, non-baryonic, collisionless matter component. In this work, we demonstrate that dark matter is not required when gravity is reformulated within Dynamic Vacuum Field Theory (DVFT), where the vacuum is a physical medium described by a complex scalar field with amplitude and phase degrees of freedom. We derive gravitational lensing, gravitational slip, parameterized post-Newtonian (PPN) screening, and Shapiro delay directly from DVFT first principles. We show that gravitational slip naturally arises from vacuum anisotropic stress, allowing lensing and dynamics to decouple without invoking unseen mass. Solar-System constraints are satisfied through strong screening, galaxy-scale lenses (SLACS and HE 0435-1223) are reproduced without dark matter halos, and the Bullet Cluster lensing-gas offset emerges as a direct consequence of collisionless vacuum phase dynamics. A quantitative Bullet Cluster calculation yields an effective lensing mass of order within 250 kpc, fully consistent with observations. We conclude that dark matter is a misinterpretation of vacuum stress-energy and gravitational slip, and that DVFT provides a unified, predictive alternative grounded in physical vacuum dynamics.
