#6: Ontological Termination and the Spacetime Recycling Boundary

This hypothesis presents a radical rethinking of cosmic acceleration and redshift by eliminating the need for the cosmological constant (Λ) and dark energy. Instead of invoking a repulsive force to explain observed redshift-distance relationships, it introduces a finite ontological boundary at the speed of light (v = c), beyond which spacetime structure ceases to exist in any measurable form. As objects approach this boundary, spacetime curvature, proper time, and metric coherence collapse — not due to energy or force, but due to the termination of existence itself. Within this framework, the apparent acceleration of galaxies is an illusion created by their approach to a structural boundary, not by dynamic expansion. The hypothesis proposes that as galaxies redshift toward the light-speed horizon, they undergo topological termination and reemerge from a folded manifold’s opposing end. This cyclical topological recycling does not violate conservation laws or require new forces. These ideas are now mathematically supported by predictive equations describing redshift, blueshift, and fold-coordinated geometry. Appendix A outlines testable predictions. Ultimately, this model preserves general relativity while eliminating the need for Λ, dark energy, or inflation — offering a self-contained and elegant alternative cosmology.
