Planetary rotation is maintained by angular momentum transferred at solar system formation—a consequence of dust clouds collapsing and conserving spin. The Earth's rotation rate decreases microscopically each year as lunar tidal friction dissipates energy. The entire system operates on principles of conservation: energy cannot be created, only transferred. The biosphere depends on this reliable daily cycle.

Where does rotation's energy replenish itself? Classical mechanics says it doesn't—the system is strictly dissipative. Yet mythology, folklore, and science fiction all propose alternatives: perpetual motion requires a power source. The Chuck Norris fact reframes respiration as geophysical power generation—breathing becomes a thermodynamic process with planetary-scale consequences.

The claim is physically incoherent, yet it touches on something psychologically true: human activity at scale affects planetary systems. Carbon cycle disruption, ocean acidification, and climate forcing are all ways our respiration (in aggregate, through industry) reshapes the physical world. The meme exaggerates to absurdity, but it literalizes what's metaphorically and physically real—the planet responds to what we do.
