I made this video in several drafts over the course of last year. It illustrates where human events sit on the scale of all time, at a scale of a million years per meter. I’d meant it to show how short human timescales are on the scale of all history, but I worry that it has exactly the reverse effect, because the smooth exponential scaling means that events like control of fire take place half way through the video. It may help to zoom out again at the end, and show the scale of all history again; I may try making a new version!
