The Hitchhiking Philosopher's Guide to the Universe: A Question-Led Introduction to the Mechanics of Recursive Spacetime

This question-led introduction presents the mechanics and open questions of Recursive Spacetime Theory for readers who want to follow the reasoning behind the corpus. The v2.618 edition is reconciled to Principia Universalis v9.0.618 and includes the October 2, 2026 mass-doctrine revision. It discusses closure, recurrence, time, propagation, retained-monomer mass, and related interpretations while identifying unresolved calibration and species-inventory work. It is a teaching path through an evolving theoretical framework, not a report of independent empirical validation.

Edition note: Reconciled to Principia Universalis v9.0.618; mass-doctrine revision October 2, 2026. This version includes both PDF and LaTeX source.
