Graphical timeline of the Big Bang

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.
