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.
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.
