The Cyclic Shell Model of the Universe

Abstract

Today's standard model of cosmology requires roughly 95% hypothetical components (Dark Matter and Dark Energy) to explain observed galactic motions and accelerated cosmic expansion. The Cyclic Shell Model presented here offers a geometric-mechanical alternative: Through a cyclic universe with incomplete collapse (Big Bounces), a fraction of matter escapes onto outer trajectories during each cycle, forming asymmetric mass shells around the remaining core. As the cycle number $n$ increases, the effective escape velocity at the boundary of the active universe drops, triggering a positive feedback loop and an accelerated mass drift ("Evaporation Effect"). After many cycles, the vast majority of total mass resides outside our visible universe. The observed accelerated expansion as well as local galactic rotation curves are not caused by internal unknown particles, but by the gravitational interaction and tidal forces exerted by the external main masses of the outer shells. This model places our present-day universe chronologically into a late "Cosmic Dawn," resolves anomalies such as Dark Flow and Hubble Tension, and provides three specific, testable predictions for modern observational telescopes.
