1 E13 s
From Wikipedia, the free encyclopedia
To help compare orders of magnitude of different times this page lists times between 320 000 years and 3 200 000 years (1013 seconds and 1014 seconds) See also times of other orders of magnitude.
- Shorter times
- 340,000 years -- half-life of curium-248
- 379 000 years -- time after the Big Bang until cosmic microwave background radiation began
- 500 000 years -- time since the colonisation of Eurasia by Homo erectus
- ~700,000 years -- time since last reversal of earth's magnetic field
- 790 000 years -- age of the earliest evidence of the controlled use of fire by Homo erectus
- 1,000,000 years -- the average lifespan of a blue supergiant star
- 1,500,000 years -- time since beginning of Pleistocene Epoch (beginning of Quaternary Period)
- 1,500,000 years -- time since end of Pliocene Epoch (end of Tertiary Period)
- 1,530,000 years -- half-life of zirconium-93
- 2,000,000 years -- duration of the Paleolithic
- 2,500,000 years -- approximate age of the genus Homo
- 2,600,000 years -- half-life of technetium-97
