The elusive unicorn of cinema! Physicists watching sci-fi movies be like: "Wait, that's not how gravity works!" *throws popcorn at screen* The sheet being pulled off to reveal nothing is basically what happens when you excitedly sit down for a blockbuster only to witness spaceships making sound in vacuum, laser beams visible in space, and explosions with convenient oxygen supplies. The laws of physics aren't just broken—they're utterly obliterated for the sake of cool special effects! Next time you hear a physicist mumble equations during a movie, just pat them on the back and whisper "it's just entertainment, my friend... conservation of sanity is more important than conservation of momentum."
