+ljmasternoob By this and many other explanations you would never see a new moon in the night sky....yet I have. The new moon as described would hit its apex or fulcrum at noon to whoever was at noon at that time. In a 24 hr period before or after, only the day light (by time, at that time would see it) side would see it as in that time period only the earths rotation would be the factor for where it appears in the sky (meaning it would not account for nigh time appearance due to 29 day orbit). Yet I have seen the new moon in the evening sky. As explained you should never see a new or near new moon at midnight on the night side of Earth. Could you comment on this? Not being malicious. Just curious.

By far the best video on the moon I've seen on YouTube, and answers all of the questions I had, and the ones I didn't.

in this episode, you say multiple times that the moon (and other sphericle objects in space) are "always lit" however in a previous episode you stated, "nothing in astronomy is permanent. ".
