The Modes That Run Past Our Physics

What we actually know

The strength of the strong interaction changes with energy; at very high energies quarks behave as though they interact more weakly. Our equations describe that running over the ranges we can test, and every test costs a larger machine. Physics does not verify a claim because a source is impressive. It verifies a claim by measuring the same thing independently, at higher precision, and seeing whether the answer moves toward or away from the prediction.

Where the extrapolation begins

A source that encodes the relationships we already know, and continues them past our experimental reach, is either a genuine extension of physics or a very good copy of our own networks fed back to us. The only way to tell is to build the machine and check — which is exactly what makes the artefact scientifically productive regardless of what it is.

What the novel invents

For three years the upper modes were officially instrument error. Then a European accelerator measured one disputed relationship at higher energy and its result moved toward the object's value: not enough to prove anything, enough to fund a larger accelerator. Beyond that point the object's curve bends away from the human model, toward something nobody can name. Sophie finds that the most interesting answer in the room, because 'we do not know' is the only sentence in the briefing that has not been negotiated.
