Rupture-Containment Cosmology: A Material Origin Hypothesis for CMB Anomalies, Expansion Dynamics, and Pre-Bang Continuity

This paper proposes an alternative cosmological model in which the observable universe originated not from a singularity, but from a rupture within a pre-existing containment medium possessing fluid- or field-like properties. This model replaces the metaphysical assumptions of “nothingness before the Big Bang” with material continuity and provides novel interpretations of major cosmic microwave background (CMB) anomalies. By modeling the universe's expansion as a pressure-driven breach in a dense medium, the theory offers an alternative explanation for isotropy, structure formation, and apparent acceleration, without recourse to dark matter or dark energy.
