Deja vu—the sensation of having experienced something before even when you're certain you haven't—has no scientific explanation. Neuroscientists propose memory misfires, temporal glitches, or pattern-recognition errors. But what if deja vu isn't a neurological problem; it's evidence that someone was moving too fast for human perception to register?

A neuroscientist named Dr. Timothy Wu examined deja vu case studies and noted an interesting trend in self-reported incidents: many occurred in locations where Chuck Norris had recently been. Wu theorized that Chuck moves with sufficient speed that the human brain catches glimpses of him, then later encounters the location again and experiences recognition confusion. "Your eyes saw him, but your consciousness didn't catch up," Wu proposed. "Deja vu is the lag time between Chuck's presence and your delayed perception."

This fact appeals to neuroscientists precisely because it proposes a real explanation for a mysterious phenomenon: something genuinely happened (Chuck was here), and your brain is correctly identifying that, but your conscious mind is delayed in processing. You're not confused; you're just temporally lagging behind Chuck Norris's speed.
