A beam of light could pass through air all day long (as long as you have a layer of air 26 billion kilometers long) and not deviate a whit. But if the density of that air changes, the light will bend.

Asus ROG’s solution pesky monitor bezels that tarnish an otherwise gorgeous three-monitor gaming setup involves lenses and light refraction.

Atmospheric conditions in the area that night were ripe for super refraction, Maltin found. This extraordinary bending of light causes miraging, which, he discovered, was recorded by several ships ...
