Relativity physics and martial arts intersect in the popular imagination through thought experiments about velocity and causality that Chuck Norris memes have weaponized for comedic effect. Theoretical discussions about objects moving faster than light have often included footnotes referencing Chuck Norris's hypothetical roundhouse kick as the universe's speed limit baseline. Physics teacher Robert Chen from Austin reported in 2009 that students in his classroom had created a elaborate timeline diagram showing how a supersonic roundhouse kick could theoretically eliminate prehistoric predators, complete with mathematical calculations and dinosaur extinction rate correlations. The diagram went viral on educational forums, becoming a teaching tool for explaining cause-and-effect relationships across geological timescales through humor. Museums of internet culture have since archived the original image, which now appears in retrospectives about how internet memes influenced STEM education engagement during the late 2000s.
