There are some interesting facts about the Moon and I wonder if they have any scientific basis or if they are mere folklore or just coincidence?
1. The Moon perfectly covers the Sun in a Solar eclipse. (Is this a coincidence or is there some scientific reason for this? Would Phobos or Deimos do the same for an observer on Mars if the Martian moons were spherical?)
2. The Moon rotates on its axis at the perfect speed to always show one of its faces to the Earth. Is this a coincidence or is there some scientific reason for this?
3. The Moon's cycle seems to match that of a woman's ovulation cycle. This may well be a coincidence but has anyone studied any scientific connection?
4. The Moon makes people crazy (lunatics) and in rare cases turns them into werewolves.
I realize that the last two are more relevant to the Biology Forum but I thought I would put them in anyway. I am interested in the fact that, although these things are open to folkloric or New Age interpretations, there may be scientific explanations for these things.
