Thanks for your comment Dr X, you are obviously well informed.
Although I certainly don’t deny being ‘dumb’ (as I have done some incredibly stupid things in my life) you are going to have to include Dr.
Peter Andreas Hansen (respected and decorated Danish mathematician and astronomer) in that category as it was he who proposed the possibility of a
‘breathable atmosphere’ to the Royal Astronomical Society in 1856.
Dr. Hansen was not the first nor was he the last of famous scientists and astronomers to propose a breathable atmosphere on the moon.
His hypothesis was based on the difference between the predicted and the actual location of the moon in orbit, which indicated a 59 kilometer
difference in the geometric center of the moon and the center of gravity of the moon.
His hypothesis was accepted until 1870 when U. S. Navy Admiral Simon Newcomb (Director of the U. S. Naval Observatory in Washington, D.C.)
‘suggested: “In the case of the evection (periodical inequality), the supposed discordance between theory and observation would not follow from
Hansen’s hypothesis, and therefore, even if it exists, cannot be attributed to that hypothesis.”
Of course Newcomb never bothered to support his objections with any proof. And because of his rank and standing within the scientific community few
bothered to argue and support for Hansen's theory fell apart, which, of course, didn't include Hansen himself who defended his theory to the end.
Both V.A. Firsoff (Strange World of the Moon) and V.A. Pickering suggest an atmosphere on the moon.
There are several reasons why we wouldn’t be able to see a breathable atmosphere if present. One is that the atmosphere might be completely free of
any dust particles that make the earths atmosphere so visible from outer space. This is particularly true because of the extremely narrow band were
these effects might be apparent. You should remember that the moon is in rotational lock and that if comeone where trying to conceal a breathable
atmosphere and its indication by occulting that all they have to worry about about is a several hundred mile wide band between the near side and far
side.
Another is that the atmosphere may collect in craters or lower depressions on the moon and would not be visible due to occulting or Raleigh
scattering.
Whoever put the moon into orbit around the earth obviously wanted to keep it a secret and it would be logical to assume that they spent every effort
to be sure that the general population of the earth wouldn’t be able to easily figure out the secret.
And I would assume that this would include making sure that an atmosphere on the moon would not be readily apparent.
Thanks for your post.
