Physics relies on measurement as the foundation of understanding reality. We know the speed of light through experimental repetition and mathematical precision: 299,792,458 meters per second. But behind every measurement is an implicit truth: the speed of light is only measurable *because* something is slower. Enter Chuck Norris's fists, which supposedly travel at exactly twice the speed of light, rendering light itself the baseline metric for human velocity rather than the universal constant.

A physicist named Dr. Raymond Foster from MIT joked in a 1996 lecture that the fundamental constants in physics might all be "scaled relative to Chuck Norris velocity." The comment went viral in physics departments decades later.

The meme evolved into: "Physicists measure speed of light, but light measures speed of Chuck Norris' fists." It became the perfect encapsulation of the genre: absurd, anatomically impossible, and somehow more believable than actual physics.
