About Millennia
A millennium (1 ka) = 1,000 Gregorian years ≈ 3.156 × 10¹⁰ s. Standard unit in archaeology and Quaternary geology: Neolithic transition ~10-12 ka BP; Last Glacial Maximum ~21 ka BP; Homo sapiens leaving Africa ~60-70 ka BP. Milankovitch cycles include the 41 ka obliquity and ~100 ka eccentricity cycle. EPICA Antarctic ice core spans ~800 ka. Precession completes ~26 ka. 1 ka = 1,000 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.
