In this episode, Howtown dives into the giant impact hypothesis (the least bad theory of lunar origin) and the growing evidence that the story of Theia may be more complicated than the textbook version. We explore how scientists measure the Moon’s distance, mass, and angular momentum, why Earth’s Moon is so unusually large compared with other moons in the solar system, and how Apollo moon rocks transformed the debate over the origin of the Moon. Along the way, we unpack Robin Canup’s simulations, synestia and multiple-impact, evection resonance, and the “isotope crisis”: why Moon rocks are chemically almost identical to Earth despite models suggesting the Moon should be made mostly from an impactor. From lunar eclipses and amateur astronomy to Apollo samples, South Pole missions, Theia, Artemis, Chang’e, and the search for mantle rocks, this is a deep look at moon formation, planetary science, and how scientists reconstruct what happened more than 4 billion years ago.
