In physics, when you propose a new field, you usually have to fit its properties to match observations. The more parameters you tune, the less convincing the model becomes — you can fit anything with enough knobs to turn.
The Selective Transient Field (STF) is different. Its mass isn't fitted. It's derived — calculated directly from the observed temporal separation between cosmic rays and gamma-ray bursts, using only fundamental constants.
This is approximately 10²⁸ times lighter than an electron
How the Mass Emerges
The derivation is elegant. Cosmic rays arrive an average of 3.4 years before merger. Gamma-ray bursts arrive an average of 71 days before merger. The temporal separation between these two phases — about 3.32 years — represents the time it takes for the STF to transition between production modes.
Key insight: In quantum field theory, a field's mass determines how quickly it can respond to changes. A massive field evolves slowly; a massless field responds instantly. The 3.32-year timescale between cosmic ray and gamma-ray burst production encodes the field's inertia — its mass.
Using the quantum relationship between mass, energy, and time (via Planck's constant ℏ), the observed separation directly determines:
Why This Matters
The fact that the STF mass is derived rather than fitted has profound implications:
- Reduces free parameters — The model goes from 5 fitted parameters to 3, making it much harder to dismiss as overfitting
- Makes predictions — A specific mass means specific behaviors at different scales
- Enables falsification — If the predicted behaviors aren't observed, the model fails
The Physical Meaning
An ultra-light mass of 10⁻²³ eV has two important physical consequences:
1. Characteristic frequency: The mass determines a natural oscillation frequency via f = mc²/h. For the STF mass, this gives f ≈ 9.5 nanohertz — a frequency that will become important when we look at supermassive black holes.
2. Compton wavelength: The mass determines the field's characteristic length scale via λ = ℏ/(mc). For the STF mass, this gives λ ≈ 0.16 parsec — roughly the scale at which supermassive black hole binaries are known to stall in their orbital decay.
These aren't coincidences. They're predictions — tested in the NANOGrav and final parsec analyses that provide independent validation of the STF framework.
A New Field?
If the STF is real, it would represent a fundamentally new component of nature — a field that couples to the rate of change of spacetime curvature, extracting energy from gravitational dynamics and producing ultra-high-energy particles.
The historical parallel is to Fermi's 1933 theory of beta decay, which introduced a new interaction (later understood as the weak force) with parameters determined by observation rather than fundamental theory. The STF framework is similarly phenomenological — derived from data, awaiting deeper theoretical understanding.
