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 Picoseconds
A picosecond (ps) = 10⁻¹² s; light travels 0.3 mm. Water molecules reorient via H-bond dynamics in ~1-3 ps, explaining microwave absorption. THz spectroscopy probes ps-scale dynamics in molecular systems. Sub-5 nm CMOS gate delays are a few ps; GaAs HEMTs reach ~0.1 ps. Muon mean lifetime = 2,197 ps. OTDR uses ps pulses for millimetre-resolution fibre-fault location. 1 ps = 10⁻¹² s.
