Why does anything happen at all?
Not why this event or that one — why is there a universe where time passes, causes have effects, where you are reading this right now?
The answer is topological. A closed causal loop above a critical threshold cannot be dark throughout — the inside is constitutive of what the loop is. Time HAPPENS because EXISTS cannot persist.
A single scalar field follows from this. Derived from four theoretical inputs, zero parameters fitted to observation. It was derived first — then found in data that had been anomalous for decades: spacecraft trajectories, galactic rotation curves, the cosmological constant, the dark energy density.
The same structure explains why you experience time moving forward, why biological death is inevitable in a precise physical sense, and why the universe exists rather than nothing.
Below the STF activation threshold. The field has not yet crossed 𝒟crit. The complexified null cone is degenerate — no doubly-ruled structure, no T² fiber. Propagation is retarded-only. No closed causal loop forms. The system is cosmologically frozen.
Above the STF activation threshold. The complexified null cone is non-degenerate — doubly-ruled, T² fiber present. Retarded and advanced Green functions pair on the Hopf torus with residues ±1. The 4π² cup product completes. A closed causal loop forms.

All papers derive from the same four inputs. No result requires observational fitting.
The same field mass ms and coupling ζ/Λ derived from first principles appear unchanged across all eleven domains. The 3.32-year clock appears independently in four separate systems.
Multi-messenger correlation analysis between UHECR, gamma-ray bursts, and gravitational wave events — identifying a candidate T = 3.32-year pre-merger signal — is documented separately at uhecrtoday.com. These results are preliminary and contested; mainstream merger theories predict no pre-merger signal. The STF framework derived on this site is independent of that observational claim.
