[asa] Question

Hi Lee,

Jon's link to talkorigins is a great place for debunking YEC arguments.

Here is the AIG claim, I would assume....
[From... http://www.answersingenesis.org/home/area/re1/chapter8.asp]
The moon is slowly receding from earth at about 1-1/2 inches (4cm) per year, and the rate would have been greater in the past. But even if the moon had started receding from being in contact with the earth, it would have taken only 1.37 billion years to reach its present distance. This gives a maximum possible age of the moon-not the actual age. This is far too young for evolution (and much younger than the radiometric 'dates' assigned to moon rocks).

Since the Moon-Earth distance is 3.85 x 10^10 cm, and the rate of migration is ~3.8 cm/yr., this suggests the Moon is on the order of 10 billion years of age.

Of course, the unknown history of the Moon's orbital eccentricity and Earth's continental distribution, along with other variables, prevent an accurate assessment of the history of the Moon's orbital migration.

For a little more detail, the migration rate is proportional to the tidal stress, and the tidal stress varies as the inverse cube. So, for instance, when the Moon was 5 times closer to the Earth, it would have received 625 times the tidal stress that it does today. This would have slowed the Earth at a much quicker rate, and, consequently, increased the migration rate of the Moon accordingly, as expressed in the conservation law of angular momentum.
