How does Ponzo Illusion and The Mueller-Lyer Illusion relate to the moon?
the “Ponzo illusion” is an optical effect that fools the eye into thinking something is a different size depending on what is in the background. a full Moon in the sky has no background, so the eye cannot properly judge its size… when the Moon is near the horizon, and photographically can be shown to be squished by thicker atmosphere, it is usually judged to be much larger, probably because of the proximity of trees, houses, a passing giraffe, things we know the size of.
