This shows the Universe’s history as if it happened in 24 hours. It starts with the formation of the Universe, the Big Bang, from 15 billion years ago, happening at midnight. At dawn, the stars and galaxies are formed. 12 noon is 7.5 billion years ago. At 6pm the solar system is formed. At 8pm the first life on Earth appears. At 10:30 pm there are the first vertebrates on land. At around 11:40pm the dinosaurs arrive, and they are gone again by about 11:55pm. At about 11:59pm and 50 seconds, are the first human ancestors. Then at midnight is the Industrial Revolution (modern age).
