Description

How special is the Earth for having a large Moon, and what can it teach us about where to look for habitable planets? In this episode we explore new research on what kind of planets are likely to get helpful moons like our own, and then we take a look at the idea of an infinitely cycling, but not repeating universe.

Giant Impacts

Sometimes size does matter. Just ask the proto-Earth how it felt to have a Mars-sized planet smack into it 4.5 billion years ago. Or check in with Mercury. Where'd your mantle go, ey Mercury? And Uranus, how's it feel to be rotating on your side? Giant impacts have been reshaping the planetary systems since there have been planets. So the next time you want to shake things up in your world, try giant impacts. Giant impacts, ho ho ho (Green Giant).
