QSFM Conceptual Index and Q&A Reference — The Quantum Spacetime Flow Model's Current Understanding of Several Physical Problems

This document is a companion conceptual index and question-and-answer reference to QSFM From Spacetime Quanta to Cosmic Metabolism – A Process Ontological Interpretation. Situated at the intersection of process ontology and natural philosophy, it treats spacetime as a quantized, dynamic, processual reality rather than a static physical background or independent container, and on this basis presents the Quantum Spacetime Flow Model's (QSFM) current understanding of a number of physical problems. The document consists of 116 numbered Q&A entries, covering nine thematic parts: general outline; spacetime, time, and causality; matter, particles, and quantum foundations; gravity, black holes, and strong fields; cosmology, dark energy, and dark matter; vacuum, particle production, and quantum phenomena; cross-scale phenomena and theoretical interfaces; numerical simulation and theoretical assessment; and philosophical extensions. Each entry is marked with a maturity level (conceptual framework, semi-quantitative, testable direction, philosophical extension) and cross-references the corresponding sections of the main text. It also identifies eight candidate testable predictions with clear observational routes, touching on minute deviations from the equivalence principle, gravitational-wave echoes, evolution of the dark-energy equation of state, primordial non-Gaussianity, vacuum birefringence, and dispersion of ultra-high-energy photons—thereby opening a dialogue between speculative ontological reconstruction and the empirical constraints of science. This document does not claim to have solved the problems listed. It is an honest record of a framework in development, including states such as "problems displaced rather than solved" and "parameters not yet derived from the QTU network." It seeks to present the explanatory potential and boundary awareness of the shift from "substance" to "process" in relation to contemporary frontier problems in physics, together with the significance this shift may hold for natural philosophy, while holding to fallibilism and openness and inviting further criticism, revision, and deepening. Note that the main text cross-referenced by this index, QSFM From Spacetime Quanta to Cosmic Metabolism – A Process Ontological Interpretation, has been uploaded to this platform by the author; readers may retrieve the full text by searching the title.
