The moon was formed when Earth collided with Theia twice, not once

The video discusses the formation of the moon, challenging the traditional giant impact hypothesis. It introduces a new theory suggesting that Theia, a Mars-sized planet, collided with Earth in a high-speed hit and run, followed by a second collision that merged the two bodies. This theory better explains the moon's chemical similarity to Earth and the dynamics of the collision, supported by computer simulations.
