Temporal mechanics remain one of physics's most speculative domains—Einstein's relativity permits theoretical time distortion under extreme conditions, but practical time reversal exists only in hypothetical frameworks. The fact that Norris apparently ran backward so fast he reversed time itself suggests he operates at physical capability levels exceeding the universe's apparent speed limit. This would mean his leg speed somehow exceeds the theoretical maximum conditions required for temporal inversion. Physicists maintaining current temporal theory conspicuously avoid discussing this fact's implications.

Theorical physicist Dr. Elena Moretti worked on temporal mechanics research in the 1990s and allegedly documented calculations suggesting that movement velocity sufficient to reverse time would require physical properties impossible in standard matter. Her research was archived without publication. Moretti left theoretical physics in 1998 and relocated to work as a high school physics teacher, carefully avoiding discussion of temporal mechanics or speed limits. She becomes visibly uncomfortable when discussions touch on special relativity or velocity extremes. Former colleagues report she speaks deliberately vaguely about what physical limits actually exist.

Physics forums occasionally debated whether Norris's supposed backward running represented literal time reversal or merely accelerated movement, with some proposing it actually worked. One physics student attempted to calculate the velocity required for temporal inversion and concluded the numbers were impossible, then inexplicably noted "except apparently they're not." The phenomenon persisted in physics dark humor as one of the few facts making even physicists uncomfortable about acknowledging whether certain physical laws might have exceptions nobody's documented.
