Two mirrors, suspended in a vacuum, are drawn to each other by gravity. If cooled enough, their wobbles can merge into one quantum dance — entanglement. This isn't sci-fi: physicists have calculated that a tiny mass is enough to test if spacetime itself is quantized.
🎯 At room temperature, thermal jolts are billions of times stronger than the gravitational attraction between the mirrors. But in the cold, below a millionth of a degree from absolute zero, gravity becomes the principal conductor of the quantum dance.
🎬 The idea of gravitational quantum linking echoes the 'graviton transmitters' from science fiction — devices that use spacetime curvature for communication. Here, it's not fiction, but a lab plan.
