There’s two explanations on the Wiki for lunar phases, one saying if the moon and sun are at the same height then there’s a half moon, and another explanation involving EA. These explanations seem to contradict each other.
And one thing I really don’t understand is how everyone on the night side of the earth would see the same moon phase from all the different angles they’re seeing the moon from.
Is there any evidence for the anti-moon existing, other than that lunar eclipses occur. It feels like another ad-hoc explanation used to explain an observed phenomenon rather than something there is empirical evidence for.
