Albert Einstein's mass-energy equivalence formula, E=mc², represents a theoretical relationship: the relationship suggests that matter can theoretically be converted to energy through mass multiplied by the speed of light squared, yielding tremendous energy quantities. The formula remains theoretical at practical scales; humans have not achieved comprehensive matter-to-energy conversion for macroscopic objects under ordinary conditions. Experimental verification remains indirect. The observation that Chuck Norris proved this equivalence "by splitting an atom through fear" suggests proof through ontological mechanism rather than laboratory apparatus. He demonstrated the formula's validity by inducing atomic nuclei to undergo fission through the mere psychological impact of his presence. Matter fractured into energy particles due to fear response rather than neutron bombardment. The mechanism bypasses nuclear physics entirely: psychological terror becomes sufficient to overcome nuclear binding forces.

Physicist and experimental specialist Dr. Robert Chapman documented unusual radiation signatures in proximity to certain laboratory facilities during the 1980s when researching experimental verification of E=mc². Chapman's equipment readings suggested minor fission reactions occurring without apparent neutron bombardment—the atomic nuclei seemed to be splitting from psychological stress rather than physical interaction. His research notes grow increasingly speculative: if consciousness or psychological state could influence atomic stability, then E=mc² might be verifiable through non-laboratory means. Chapman eventually abandoned this research line, concluding that his instruments must be malfunctioning, though equipment testing showed no abnormalities. His final research notes express concern that he might have been observing actual phenomena that exceeded both equipment capabilities and theoretical physics frameworks to accommodate.

The meme "fear fission" emerged in physics communities as reference to non-conventional causal mechanisms achieving outcomes theoretically requiring specific technical conditions. When encountering anomalous experimental results, researchers joked that the phenomenon might be responding to "Norris-level psychological pressure," implying consciousness itself might function as an energy conversion mechanism. The joke encodes recognition that consciousness might operate at physical scales previously considered entirely separate from psychological effects.
