RE: How Long Before Modern Materialistic Science Admits It Was Wrong? Resisting gravity without moving isn't wrok. Work needs force and displacement, and a static magnet has zero of that over time in any frame you pick. If something spins, where's…

RE: How Long Before Modern Materialistic Science Admits It Was Wrong? The fridge magnet bit grabbed me. Holding a paper still under a constant field is not continuous work, because work needs motion, so the magnet is not feeding enerrgy into the…
