THE END OF ENTROPY

The coherence threshold
Year 2437. The Moon was no longer simply a natural satellite.
—
From the orbital station where he spent most of his sleepless nights, Dr. León
Arístides Kadar observed the lunar surface. Seen from there, it looked the same as
always: craters, shadows lengthened by the grazing sunlight, absolute silence.
Nothing suggested that anything had changed.
However, beneath the regolith layer, several kilometers deep, things were very
different.
Down below, in chambers maintained at temperatures near absolute zero, existed
spheres of quantum computing. There were no lights, because light was unnecessary.
There were no human operators, because any breathing or bodily movement
would generate unacceptable heat and thermal noise. Only swarms of nanomachines
patrolled the conduits, adjusting atomic alignments, correcting minute deviations,
preserving the quantum coherence of billions of entangled qubits.
They were called "cold factories." The name was inadequate, but it stuck. They
didn't produce material objects. They produced continuity.
— The cumulative orbital deviation has exceeded the statistical threshold of significance.
Leon didn't answer immediately. He had traveled through time twice—physical
journeys, not simulations. In both cases, the process had been the same: a transition
without light or sound, only an intimate resistance, as if every atom in his
body had to pay a toll to the fabric of spacetime. 3After those journeys, he understood
something that theory already suggested: time wasn't an open line. It was a closed structure, a torus
in which the past didn't precede the future, but rather sustained it from within.
— Seventeen millimeters on the main axis, accumulated over the last eleven years.
Seventeen millimeters. A negligible distance for any casual observer. A catastrophic
distance for the gravitational dynamics of the Earth-Moon system when the
contribution of coherent information was considered.
