So the answer to the question "Why do the planets and moon glow?" Is "because they reflect light."
Well, yeah. But why do they reflect light?
The answer, which I should have considered, is that everything reflects light. Light hits something, bounces off, thus we have colors and vision.
Light will reflect off anything in the universe that isn't pure black, which is a rarity.
But I'm still puzzled over the glow factor. I understand that all objects reflect light. But being able to see that glow, from 250,ooo miles away (such as the moon) and much further for the planets, still baffles me.
It's a difficult concept for me.
To be continued on HF - I think there is some esoteric relative truth here that I've missed, and more specifically a personal truth - a sort of universal law, I'm thinkin'.
