The stronger the quantum chaos, the faster it turns into order — thanks to quiet zones isolated from external noise.

Hot water sometimes freezes faster than cold — this is the Mpemba effect. In the quantum world, it’s even more astonishing: a system bubbling with disorder (with high entropy) can settle incredibly faster than one that is almost calm.

The solution lies in islands of silence within any system — regions untouched by the destructive noise of the environment.

In a panicking crowd, such 'islands' are people who don’t hear the screams and clearly follow a plan; they are the ones who turn chaos into order.

The larger the system, the more such regions exist, and the calming cascades like an avalanche. A mathematical model confirmed that the speed grows exponentially: large structures seem to sweep out disorder with acceleration.

The most striking part is the backlash from the environment: at the moment of order, it experiences a jolt, as if time briefly reverses.

The discovery not only explains the paradox but also provides a key to ultra-stable quantum computers: instead of fighting noise, we can harness its rapid neutralization.

Entropy isn't just a measure of chaos: black holes in the Universe possess the maximum possible entropy.
