一小时看完 45 亿年

Kurzgesagt's hour-long animated film that compresses Earth's 4.5 billion year history into one hour, roughly a million years per second. It follows the evolution of life through to humanity's tiny final stretch.

Why HN likes it: HN commenters recommend it for the sense of perspective it gives on deep time and how brief human history is.

“This video puts things into perspective, mapping the whole of 4.5B years of Earth history to 1 hour”
