The Weird Optical Illusion that Changes the Moon's Size

The video explores the moon illusion, a phenomenon where the moon appears larger on the horizon than when high in the sky. It discusses angular size, the moon's elliptical orbit, and why the moon seems bigger on the horizon. Two main hypotheses are examined: the relative distance hypothesis, which suggests our brains perceive horizon objects as larger, and the relative size hypothesis, which involves contextual size perception. Modern neuroscience suggests the relative distance hypothesis may be more accurate, involving the ventral and dorsal streams of visual processing.
