When Worlds Collide

Our solar system used to be a much more violent place, with early planets crashing into each other to create the worlds we see today. The talk is about how we use supercomputer simulations to study these cataclysmic giant impacts, and how high-resolution advances are helping us to tackle unsolved mysteries like the origin of our Moon, and how Saturn got its rings.
