Where Did the Moon Come From?

The video explores the origin of the Moon, focusing on the Thea impact hypothesis, which suggests a Mars-sized object collided with Earth, forming the Moon. Despite supporting evidence, such as the Moon's lower density, challenges arise due to the similar geochemical composition of Earth and Moon rocks. Alternative theories, like capture, formation, and fission, are discussed, each with its own shortcomings. The video highlights the complexity of the Moon's origin, showing that some cosmic mysteries remain unsolved.

What does the fission theory propose about the formation of the Moon?
