This timeline of the Big Bang shows a sequence of events as currently theorized by scientists, but not yet completely proven. Dark Ages.

It is a logarithmic scale that shows second instead of second. For example, one microsecond is . To convert -30 read on the scale to second calculate second = one millisecond. On a logarithmic time scale a step lasts ten times longer than the previous step.
