- The values for the accumulation rate of dust which
- were used to give this "20- 40 feet" estimate (I've heard
- higher) were taken from measurements made on earth in the late
- 1950s. The authors of the paper reporting this work were
- well aware that there would be some contamination of their
- sample by terrestrial dust, and accordingly gave a range
- of possible values for the accumulation rate of dust.
- Natually, the creationists took the top end of that range
- (and cited it as the "measured value") for their "prediction".
-
- Space based measurements have long since shown the actual
- accumulation rate to be far smaller than that still quoted
- by creationists. The amount of dust on the moon actually
- supports a lunar age of several billion years, not several
- thousand.
-
- All this has been known for well over a decade (you will find
- some of this in Kenneth Miller's article in "Science and
- Creationism", Ashley Montagu, ed, 1984). Nonetheless
- creationists still cite this refuted moon dust argument as
- if it had some validity. Does this tell you something about
- their honesty?
