The Moon affects rainfall here on Earth...and we have no idea why

Even the most ridiculous and obviously false bits of folklore can turn out to have a kernel of truth. It turns out the Moon really can affect how much rain the Earth gets. The reason why is still a mystery.

There's an old wives' tale that says rain follows both the full and new Moon. Scientists found some proof of this back in the 1960s, and now a new study reveals that the Moon could be responsible for as much as one to two percent of rain and steam runoff. But, as you can read over at ScienceNow, the actual cause of this phenomenon is still anyone's guess. One idea holds that the Moon is distorting the magnetosphere, and another theory says it might be meteoric dust, but really we have no idea. Until then, we can just update the tally and say it's now insane theories two, regular theories still a billion.
