Several year's ago, someone on a Usenet group posted a picture of pingoes or the like.
I remarked that they looked extraordinarily like the craters of the moon. To much derision of course.
I then started to think about the structure of lunar craters.
Most of them appear as pock marks.
For a meteorite to cause pock marks, they have to hit nearly dead on a line aimed at the centre of the planet/satellite.
That is not the normal trajectory of meteorites.
In fact I don't believe many have approached earth at an angle anywhere near 90 degrees to tangential.
Statistically, the chances of a meteorite falling plumb central to the surface; dead on, is one in 180 in any of 360 directions.
I am not sure if the chance is 1 in 360 by 180 but it close to that number.
The only reason the scientific community believes there is no water on the moon is that none has been found there.
Being a one time gun nut and hunter, I know that the reason you can't see a meal in the bushes is not because you are in a field minus rabbits but because you are looking in the wrong part of the field or because they have seen/smelled/heard you coming.
Applying that to the forays and hunting expeditions to the moon carried out by people who have been misled to believe there is no water on the moon...
Well you can fill in the blanks on that one without my help.
There then followed a discussion about me. Very little was said about lunar craters:
Sad, or what?
