A research programme in the foundations of physics grows out of Chapter 7 of The Billiard Ball Universe, which states the picture's open problems as problems. First published paper:

Taking the kinematic reading of cosmological redshift seriously (2026) — three observational audit bounds and one well-posed open problem; no new predictions claimed. Zenodo: doi.org/10.5281/zenodo.22721723.

The book's manuscript sources, correction record, and research memos are public: github.com/nielsbj/billiard-ball-universe. ORCID: 0009-0006-0120-6061.

A working developer's labour of passion. More to come.
