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 ${\displaystyle 10\times \log _{10}\{t\))$ where ${\displaystyle \{t\))$ is the time since the Big Bang expressed in years. Example: one million years is ${\displaystyle \{t\}=1{,}000{,}000;\ \ 10\times \log _{10}\{t\}=10\times 6=60}$.
