This
timeline of the Big Bang shows the sequence of events as predicted by the
Big BangThe Big Bang theory is the prevailing cosmological model that explains the early development of the Universe. According to the Big Bang theory, the Universe was once in an extremely hot and dense state which expanded rapidly. This rapid expansion caused the young Universe to cool and resulted in...

It is a
logarithmic scaleA logarithmic scale is a scale of measurement using the logarithm of a physical quantity instead of the quantity itself.A simple example is a chart whose vertical axis increments are labeled 1, 10, 100, 1000, instead of 1, 2, 3, 4...

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.

This is the timeline of the Universe from Big Bang to Heat Death scenario. The different Eras of the Universe are shown.Usually the logarithmic scale is used for such timelines but it compresses the most interesting Stelliferous Era too much as this example shows. Therefore a double-logarithmic...
