LUNAR THEORY AND EVIDENCE

After moon rocks were examined, many scientists were interviewed to
learn which theory of the moon's origin they favored before and after
analyzing the rocks. National Aeronautics and Space Administration
officials, who funded the inquiry, hoped that evidence of the moon' s
composition would produce a consensus about the best theory.

"It didn't work out that way," Harvard astronomer A.G.W. Cameron (who
thinks the moon was wrenched from the molten earth by an object twice
as heavy as Mars) recalled. "After examining the lunar samples,
everyone clung to the same scenario he or she favored before the moon
landings." (Harvard University Gazette, Sept. 18, 1997)
