I know it doesn’t seem like it, but this is a serious question. This morning, I looked up into the sky and saw the crescent moon overhead. I remember a few weeks ago the moon was in the sky in the morning too, but it was a full moon then. So, here’s my question:
Since the phases of the moon are caused by the angle of sunlight and the location of the moon, how is it possible for the moon to be in the sky at the same time as the sun and have it be a full moon one time and a crescent moon the other time?
(BTW: I’m have a theory on this that I’m pretty sure about, but I figured I’d throw it out here and see if anyone else cares about it first.) :-)
