Overheard: large-impact hypothesis

Astronomy 210L, Fall Semester 2008
Cuesta College, San Luis Obispo, CA

(Overheard in lab during an analysis of Moon formation theories, namely the large-impact hypothesis, where the Moon formed from the crustal debris flung off of the Earth from a Mars-sized protoplanet impactor.)

Student 1: "Wait...does that mean that the Moon is the Earth?"

Student 2: "What? The Moon is the Earth?!?"

Esprit d'escalier:
Instructor: "Dude! The Moon is the Earth. Have another brownie."
