About Gigayears
A gigayear (1 Ga) = 10⁹ yr ≈ 3.156 × 10¹⁶ s - the timescale of stellar evolution and cosmology. Universe age: 13.787 ± 0.020 Ga (Planck CMB). Sun: 4.603 Ga old; red giant in ~5 Ga. A 0.1 M☉ red dwarf lives ~10,000 Ga. Uranium-238 half-life = 4.468 Ga (used in radiometric dating). Proton decay (GUT prediction): ~10³⁴ yr = ~10²⁵ Ga. 1 Ga = 10⁹ 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.
