We’ve all heard it — “time is the fourth dimension.” It’s a phrase tossed casually in physics documentaries, sci-fi shows, and classrooms alike. But what if this idea, however elegant and useful in equations, is fundamentally mistaken?
What if time isn’t a dimension at all?
This isn’t just philosophical nitpicking. There’s growing evidence from physics, logic, and experience that time behaves very differently from space. And treating them as equivalent — as four equal coordinates in a “spacetime fabric” — might be the greatest conceptual mistake in modern physics.
