Shubin reveals the extraordinary cosmic and evolutionary adventure of our own bodies. The one place where universe, solar system and planet merge is inside your body. Shubin shows how the origin of the Moon is tied to our internal body clocks; how the vast amounts of water on Earth and inside all living creatures crossed the deepest stretches of space to us; how strange fluctuations in the orbits within our solar system have led to our irregular ice-ages; and how tiny imbalances in the chaos immediately after the Big Bang can explain why matter exists at all.
