The giant impact hypothesis—the favored scientific hypothesis for the formation of the Moon—proposes that the Moon was created from the debris of a collision between a young Earth and a Mars-sized celestial body. Evidence for the hypothesis includes Moon samples indicating that its surface was once molten, the Moon’s apparently relatively small iron core and lower density than that of Earth, and evidence of similar collisions in other solar systems. What evidence is inconsistent with the theory? Discuss
