This is the timeline of the Universe from Big Bang
Big Bang
The 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...

Heat death of the universe
The heat death of the universe is a suggested ultimate fate of the universe, in which the universe has diminished to a state of no thermodynamic free energy and therefore can no longer sustain motion or life. Heat death does not imply any particular absolute temperature; it only requires that...

Usually the logarithmic scale
Logarithmic timeline
A logarithmic timeline is a timeline laid out according to a logarithmic scale. This necessarily implies a zero point and an infinity point, neither of which can be displayed. The most natural zero point is the Big Bang, looking forward, but the most common is the ever-changing present, looking...

 is used for such timelines but it compresses the most interesting Stelliferous Era too much as this example shows. Therefore a double-logarithmic scale s (s*100 in the graphics) is used instead. The minimum of it is unfortunately only 1, not 0 as needed, and the negative outputs for inputs smaller than 10 are useless. Therefore the time from 0.1 to 10 years is collapsed to a single point 0, but that doesn't matter in this case because nothing special happens in the history of the universe during that time.

Comparison of log10 and log10log10 scales
year | log10 year | combination of log10log10 year and
-log10(-log10 year)
1010000 10000 4
101000 1000 3
10100 100 2
1010 10 1
102 2 0.30
101 1 0
100 0 undefined but here forced to 0
10−1 -1 0
10−2 -2 -0.30
10−10 -10 -1
10−100 -100 -2


The seconds in the timescale have been converted to years by using the Julian year.
