TED-Ed: The moon illusion - Andrew Vanden Heuvel

The video explores the moon illusion, where the moon appears larger near the horizon than overhead. Despite historical attempts by great minds, a definitive explanation remains elusive. Theories like atmospheric lensing, Ebbinghaus, and Ponzo illusions are discussed, but each has limitations. Convergence Micropsia, a modern theory, suggests that the brain's perception of distance affects the moon's apparent size. The debate continues as no single explanation fully accounts for the phenomenon.

What complications arise when trying to explain the moon illusion, particularly in relation to pilots and planetarium observations?

How does Convergence Micropsia contribute to our understanding of the moon's apparent size?
