Graphical timeline of the Big Bang


This timeline of the Big Bang shows a sequence of events as currently theorized by scientists.

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.
