Has it been mentioned that as dust and slow micrometeors fall from space to Earth in the amount of many tons a year, wouldn't that also be happening
to the Moon even though it has a smaller presence? And given that light travels so well in a vacuum (being visible for long distances) would not a
little reflecting dust up there go a long way toward being visible in addition to "levitating" surface dust, etc.?
Has the new revelations about the amount of water on the Moon's surface--I think it was estimated at one litre per ton--been factored into this long
discussion?
