Why Does the Universe Expand?

- Copernicus proposed a Sun-centered model with fewer ad hoc adjustments than the geocentric model, recognizing retrograde motion as parallax from Earth's orbit.
- The standard cosmological model (ΛCDM) relies on patches like inflation and dark energy to fit observations, similar to Ptolemaic epicycles, while failing to explain why the universe expands.
- The author's PhD work broke the assumption that matter is on average at rest, proposing a model where matter moves uniformly, leading to a universe that necessarily expands at the observed rate.
- The author faced academic resistance despite the model's potential to resolve fundamental cosmological problems, eventually linking black hole collapse and cosmic expansion.
- The universe expands because collapsed matter transitions into an expanding cosmology, with expansion rate fixed by the cosmological constant alone.
