Compressed Spacetime Halo Theory (CSHT)

Compressed Spacetime Halo Theory (CSHT) proposes a geometric and physically motivated alternative to particle-based dark matter models. In this framework, galactic halos are interpreted not as distributions of unseen particles, but as persistent, finite spacetime-compression structures generated during baryonic structure formation. The theory explains flat galactic rotation curves, halo boundaries, and gravitational lensing as consequences of spacetime geometry, without modifying the fundamental field equations of general relativity or introducing new forces. CSHT is explicitly falsifiable and makes testable predictions that distinguish it from standard dark matter scenarios. This project presents the conceptual framework, physical motivation, and observational predictions of CSHT as a late-time, structure-level theory.
