BCT Letter 202: The Catastrophe Calendar — Plasma Discharge Events as OHC Hopf Annihilation and a Geometric Chronology Independent of AD Dating

Revised chronology researchers (Velikovsky, Sweeney, Hall, Talbott) have identified structural problems in conventional AD chronology. The BCT Superfluid Lattice Model offers an independent geometric chronology: catastrophic plasma discharge events — OHC Hopf charge annihilation events — leave BCT Bessel ratio signatures in geological, archaeological, and isotopic records dateable independently of textual tradition. Three independent chronometers are identified: BCT SAR fractal dimension D = 1 + r_tet/r_oct = 1.5426, isotopic production spikes (¹⁴C, ¹⁰Be), and petroglyph Bessel geometry (Peratt corpus). BCT Prediction #246: Bronze Age Collapse sites share fractal dimension D = 1.5426 ± 0.05 consistent with simultaneous plasma discharge. The geometry does not need a calendar. Zero free parameters.
