1 E17 s
From Wikipedia, the free encyclopedia
To help compare orders of magnitude of different times this page lists times between 1017 seconds and 1018 seconds (3.2 and 32 billion years) See also times of other orders of magnitude.
- Shorter times
- 3.5 billion years — age of oldest cellular life (Prokaryotes)
- 3.7 to 3.9 billion (3.7e9 to 3.9e9) years — age of the Mare Imbrium, the Lower Imbrian epoch
- 4.468 billion years — half-life of uranium-238
- 4.5 billion years — age of the Earth (see: Precambrian)
- 10 billion years — expected main sequence lifetime of a G2 dwarf star (like the Sun)
- 13.7 ± 0.2 billion years (4e17 seconds) — estimated age of the universe according to the Big Bang theory
- Longer times
