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 Yoctoseconds
A yoctosecond (ys) = 10⁻²⁴ s - the smallest named SI prefix time unit. Light travels ~0.3 fm in 1 ys, about one-tenth the proton charge radius. Strong-force quark binding operates on ~1 ys timescales; W and Z boson lifetimes are ~260-290 ys. Lead-lead collisions at the LHC produce quark-gluon plasma that thermalises within a few ys. These timescales are inferred from decay widths via ΔE × Δt ≥ ℏ. 1 ys = 10⁻²⁴ s.
