About Megayears
A megayear (1 Ma) = 10⁶ yr ≈ 3.156 × 10¹³ s - the timescale of geology and tectonic evolution. The K-Pg mass extinction at 66.0 Ma; Cambrian explosion ~538.8 Ma; Great Oxygenation Event ~2,400 Ma. Plate motion at 2-10 cm/yr = 200-1,000 km per Ma (Atlantic ~3,000 km wider since Pangaea rifting ~200 Ma ago). Background extinction rate measured in extinctions per million species-years. 1 Ma = 10⁶ yr.
About Zeptoseconds
A zeptosecond (zs) = 10⁻²¹ s. In 2020, physicists at Goethe University Frankfurt measured the H₂ photoionisation time at ~247 zs - the first direct event measurement at this timescale. W-boson lifetime ~300 zs; strong-force quark confinement dynamics ~1-3 zs. These timescales are resolved via the energy-time uncertainty relation and lattice-QCD simulations. 1 zs = 10⁻²¹ s = 1,000 ys.
