Hot on the Jim Marrs’ post “Who Parked Our Moon” that resurfaced last week, now the highly respected science journal Nature gets in on the act of questioning just what the deal is with our moon. Author Robin Canup, associate vice-president of the Planetary Science Directorate of Southwest Research Institute, Boulder, Colorado, says current theories on the formation of the Moon owe too much to cosmic coincidences:
The Moon is more than just a familiar sight in our skies. It dictates conditions on Earth. The Moon is large enough to stabilize our planet’s rotation, holding Earth’s polar axis steady to within a few degrees. Without it, the current Earth’s tilt would vary chaotically by tens of degrees. Such large variations might not preclude life, but would lead to a vastly different climate.
Knowing how the Moon was made is central to understanding Earth and the formation of other planets.
