Graphical timeline of the Stelliferous Era

From HandWiki - Reading time: 2 min

Short description: none

This is the timeline of the stelliferous era but also partly charts the primordial era, and charts more of the degenerate era of the heat death scenario.

The scale is [math]\displaystyle{ 10 \times \log_{10}\{t\} }[/math] where [math]\displaystyle{ \{t\} }[/math] is the time since the Big Bang expressed in years. Example: one million years is [math]\displaystyle{ \{t\} = 1{,}000{,}000;\ \ 10 \times \log_{10}\{t\} = 10\times 6 = 60 }[/math].
