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 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. : The seconds in the timescale have been converted to years by using the Julian year. ==See also== *Timeline of the Big Bang *Graphical timeline of the Big Bang *Heat death of the universe *List of other end scenarios than Heat Death *Timeline from Big Bang to the near cosmological future *Graphical timeline of the Stelliferous Era *Tiny Graphical timeline from Big Bang to Heat Death.
