GoKawiilDeveloper builds simulator explaining the 'lunar terminator paradox'
A programmer created a visualization tool to explain why the moon's illuminated side can appear to point upward after sunset, contrary to the naive expectation that it should point down toward the sun. Using the program, they found that when the moon is high in the sky rather than at the horizon, an observer looks at it from below, causing the dark portion to appear as a slice missing from the bottom rather than the whole underside. The effect is most visible with a nearly full moon and produces no visible paradox with a half-moon.
