Naw, not wishful thinking, or noise. The Moon doesn't retain water, due to mass, density, and lack of atmosphere, while the Earth does.
Wrong! If you have mini-comets impacting the lunar surface at its terminal velocity, low as that may be, you would still see the H2O (volatiles) in the samples brought back by the apollo astronauts. Reference the Lunar Source Book, a compendium of known lunar facts, published after 1973 when the apollo program was terminated. There is no, repeat NO, evidence for "wet" impacts in lunar surface rocks; as Louis Frank's mini-comet theory predicts. Again, you are faced with a dilemma : 5% of all meteorite mass that comes into the earth-moon system impacts the MOON, that's a known factoid. Over past eons a continual spray of mini-comets would then show up in lunar surface rocks...it doesn't, the moon is as dry as a bone. Ignoring inconvenient facts is not how one does science. Or as Sherlock Holmes would say : the dog that didn't bark in the night(no lunar water traces)is telling us something(besides Frank's theory being wishful thinking)...are you listening?
