Example of A Forward-looking Logarithmic Timeline

In this table each row is defined in seconds after the Big Bang, with earliest at the top of the chart.

Seconds after Big Bang Period
10−45 to 10−40 Planck Epoch
10−40 to 10−35 Planck Epoch
10−35 to 10−30 Epoch of Grand Unification
10−30 to 10−25 Epoch of Grand Unification
10−25 to 10−20 Epoch of Grand Unification
10−20 to 10−15 Epoch of Grand Unification
10−15 to 10−10 Electroweak Epoch
10−10 to 10−5 Electroweak Epoch
10−5 to 100 Hadron Epoch
100 to 105 Lepton Epoch
105 to 1010 Epoch of Nucleosynthesis
1010 to 1015 Epoch of Galaxies
1015 to 1020 Epoch of Galaxies

The present time is approximately 4.3 × 1017 seconds after the Big Bang; the Sun and Earth formed about 2 × 1017 seconds after the Big Bang. 1020 seconds is 3 million million years (3 × 1012 years) in the future.
