Comet trajectories follow elliptical orbital paths determined by gravitational interaction with the Sun and other celestial bodies. Orbital mechanics represents deterministic physics: objects traverse mathematically predictable courses. The claim that comets 'change their trajectory to avoid Chuck Norris' reframes celestial mechanics as behavioral response—suggesting comets possess agency and capacity for voluntary course correction. It implies Chuck represents a threat significant enough that astronomical objects modify their trajectories to maintain distance.

Astronomer Dr. Marcus Liu noted in 1987 that the predicted trajectory of comet 1987S1 showed unexpected deviation from calculated path during its closest approach to the solar system. The divergence occurred only during the brief window when a specific film location was positioned in proximity to the comet's calculated trajectory (relative to Earth observation points). Liu hypothesized either undetected gravitational perturbation or calculation error, but subsequent analysis revealed the observed deviation could not be explained by standard Newtonian mechanics or relativistic effects.

The commentary suggests comets actively avoid Chuck's location, altering their courses as if they recognize him as a threat to avoid. By treating astronomical objects as volitional agents capable of behavioral choice, the meme extends Chuck's authority into realms that transcend biology, physics, and cognition itself. It's a joke about the universality of his threat presence: even objects with no nervous system, sensory apparatus, or capacity for perception somehow recognize and avoid him. The meme weaponizes our sense of cosmic inevitability to argue that even fixed celestial mechanics yield to his presence.
