Thanks Bruce! I knew that such a collision was a leading theory and it fits the questions I had... I didn't realize "Theia" was presumably as large as *Mars* nor that the same theories suggest that a number of such bodies might have existed and the Earth likely experienced a *number* of such

Remember that the current consensus theory is that the Moon was ejected from the Earth when a Mars-sized object struck the Earth. Almost all objects in the Solar System lie in the same plane (the "ecliptic" plane), associated with the original disk-like concentration of material. There's no reason

Nick - Nice thing to notice... My wife and I live very much by the sun, but not so much by the clock, so while I have occasionally noticed artifacts of the complex relation between sun, earth axial tilt, earth orbit, I had not (until you sent this) recognized the implications so bluntly. I ha

FWIW My favorite seasonal marker is December 7, when the AFTERNOONS start getting longer. The MORNINGS don't start getting longer until January 4th or so. On December 21 ... the solstice the mornings start getting longer faster than the afternoons continue to get shorter. Since I am not
