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 10×log10year{\displaystyle 10\times \log _{10}\mathrm {year} }. Example one million years is 10×log101000000=10×6=60{\displaystyle 10\times \log _{10}1000000=10\times 6=60}.
