On 10 November 1971, Dr. Harold Urey, a Nobel prize-winning chemist and lunar scientist, stated “I do not know the origin of the moon, I’m not sure of my own or any other’s models, I’d lay odds against any of the models proposed being correct.” Robert Treash, “Magnetic Remanence in Lunar Rocks,” Pensee, Vol. 2, May 1972, p. 22.

“In astronomical terms, therefore, the Moon must be classed as a well-known object, but astronomers still have to admit shamefacedly that they have little idea as to where it came from. This is particularly embarrassing, because the solution of the mystery was billed as one of the main goals of the US lunar exploration programme.” David W. Hughes, “The Open Question in Selenology,” Nature, Vol. 327, 28 May 1987, p. 291.

. “This is a problem for the giant impact theory, says [Erik] Hauri. ‘It’s hard to imagine a scenario in which a giant impact melts, completely, the moon, and at the same time allows it to hold onto its water,’ he says. ‘That’s a really, really difficult knot to untie.’ ” Nell Greenfieldboyce, quoting Erik Hauri, “Glass Beads from Moon Hint of Watery Past,” www.npr.org/templates/story/story.php?storyId=92383117, 12 July 2008.
