The Universe Has a Clock Speed A Plain-Language Introduction to the Temporal Selection Framework

This introduction has been revised to accompany the full TSF paper series. The opening has been rewritten to remove an informal analogy and replace it with a direct statement of the framework's core claim, appropriate for a scientific audience. The Hubble tension discussion now explicitly distinguishes the raw observed value (8.3%) from the TSF prediction (8.8%), identifying the 0.5% residual as a secondary prediction of the framework rather than a free parameter. The locking relation (DM/B − 5.0)/5.0 = ΔH₀/H₀ = λ = 0.088 is now displayed explicitly. A new paragraph in the Deeper Picture section references the third technical note in the series (Grounding TSF Conjectures in Established Physics: Five Research Directions) and its programme of independent derivations from holographic bounds, information theory, ADM gravity, and thermodynamics. References updated to include all three technical papers with live DOI hyperlinks.
