Detailed logarithmic timeline

Detailed logarithmic timeline

This timeline allows one to see the whole history of the universe, the Earth, and mankind in one table. Each row is defined in years ago, that is, years before the present date, with the earliest times at the top of the chart. In each table cell on the right, references to events or notable people are given, more or less in chronological order within the cell.

Each row corresponds to a change in log(time before present) of about 0.1 (using log base 10), similar to Renard numbers. The table for recent events assumes a present of 1 January 2010.
