IV.R379 — Comparison with other theories
No other framework derives alpha from first principles with zero free parameters; the Standard Model treats alpha as input, GUTs introduce new parameters, string theory has ~10^500 vacua with no selection principle; the spectral formula is the first candidate producing the correct ~1/137 order.
