How a Frozen Earth Gave the Moon Its Shape

The video explores the mystery of the moon's equatorial bulge, which is larger than expected based on its rotation. A new study suggests that the moon's early rapid rotation and proximity to Earth contributed to this bulge. The study also implies that Earth's early tidal interactions were weaker, possibly due to a global ice sheet, known as Snowball Earth. This research provides insights into the early history of both the moon and Earth.
