Graphical timeline of the Big Bang

Main article: Chronology of the universe

This timeline of the Big Bang shows the sequence of events as predicted by the Big Bang theory, from the beginning of time to the end of the Dark Ages.

It is a logarithmic scale that shows $10 \cdot \log_{10}$ second instead of second. For example, one microsecond is $10 \cdot \log_{10} 0.000 001 = 10 \cdot (-6) = -60$. To convert -30 read on the scale to second calculate $10^{-\frac{30}{10}} = 10^{-3} = 0.001$ second = one millisecond. On a logarithmic time scale a step lasts ten times longer than the previous step.
