Eternal Causal Patch Cosmology: A Discrete, Self-Sustaining Model of the Universe

This paper introduces "Eternal Causal Patch Cosmology" (ECP), a novel framework proposing that the universe operates as a discrete, self-sustaining network of causal patches rather than a continuous spacetime manifold.

ECP addresses fundamental problems in cosmology by eliminating singularities, explaining dark energy as a causal boundary effect, and providing a natural mechanism for cosmic self-organization. The model suggests that what we perceive as cosmic expansion is actually the discrete evolution of causal connectivity between fundamental spacetime patches.

Key implications include:

1. Resolution of the singularity problem through discrete causal structure

2. Natural emergence of dark energy from causal patch dynamics  

3. A self-sustaining universe with no beginning or end requirement

4. Testable predictions for CMB anisotropy and gravitational wave backgrounds

The framework bridges general relativity, quantum information theory, and causal set theory, offering a new paradigm for understanding cosmic evolution.
