Looking into water, objects are visually displaced by light refraction.
Similarly, looking out of water from within also produces refraction.
Is this entirely because of the refraction by water, or does atmosphere produce its own refraction? Are we evolved to perceive our atmosphere as “clear,” but if an alien from a planet with a different atmosphere came to earth, would they be thrown by our atmosphere’s unique refraction? Or are the gases that make up our atmosphere non-refractory?
If we could somehow survive (and see) in the vacuum of space, would all objects appear visually displaced, like they would looking into water?
