Water always flows downhill, and heat from hot to cold. That's what энтропия dictates. But the quantum world finds loopholes. Physicists made light particles interact with hot and cold environments in an uncertain sequence — like a flipped coin that hasn't landed yet.

Imagine holding a soft rubber ellipse that represents all possible positions and velocities of a massive mirror. Gravitational decoherence acts like an invisible sculptor: it slowly crumples this ellipse, turning it from a sharp quantum shape into a blurred smudge.
