Why 137? A hydrogen atom spans 137 Compton wavelengths -- one electron orbit contains 18,800 Compton "ticks." Are these brute facts or signatures of a cosmic Central Limit Theorem converting quantum noise into classical atoms? The cosmological constant is an even stronger candidate: 10^122 horizon pixels produce the observed dark energy. Honest about gaps. https://doi.org/10.5281/zenodo.20182909

Fine-structure constant sensitivity of the Th-229 nuclear clock transition: https://www.nature.com/articles/s41467-025-64191-7 -> How constant is the #FineStructureConstant? https://www.tuwien.at/en/phy/ati/news/wie-konstant-ist-die-feinstrukturkonstante - in 2024, TU Wien presented the world's first nuclear clock; now it has been demonstrated that the technology can also be used to investigate unresolved questions in fundamental physics.
