The Three Falsifiable Predictions

Vacuum-Inflow Cosmology stakes three falsifiable predictions that distinguish it from ΛCDM and Newtonian gravity. Each is a specific, registered, gated test whose failure would refute the framework, not a degenerate match to existing data. These predictions are the volume's actual scientific content — claims that put the medium picture at genuine risk.

Beyond the degenerate agreement catalogued in the ledger, the volume stakes three predictions that distinguish it from ΛCDM and Newtonian gravity and could falsify it. Each is registered and gated, with a stated failure condition, so the framework is exposed to refutation rather than fitted to data after the fact. One prediction fixes the gamma-dispersion scale near 882 GeV = √2·ħc/πa.

The three falsifiable predictions

  1. a₀∝ cH₀: an environment/epoch correlation. Because a₀=cH₀/2π is tied to the cosmological background rate (Ch 6, Ch 7), the galactic acceleration scale should track the local environment and cosmic epoch. MOND, in which a₀ is a universal constant, predicts no such variation. A measured correlation of a₀ with environment or redshift would favour this framework; its absence would favour MOND.
  2. Angular-size minimum at z≈1.72. Standard rulers should appear smallest at z≈1.72, not ΛCDM's ≈1.61 (Ch 7), provided the lattice optics realizes the reciprocity focusing flagged in the open problems (absent it, θ(z) is monotonic with no minimum). Distance-ladder-free in principle, but a weak test in practice: the θ(z) curves differ by <0.3% near the flat minimum, far below the gtrsim20% scatter of the standard rulers (compact radio sources) that reach these redshifts, so current data cannot resolve the 0.13 shift in z_(min).
  3. Gamma as a quasi-longitudinal mode (or vacuum dispersion). Two linked predictions follow from the optics of Ch 2. (i) Angle: the physics-volume relation sinχ=λ/(mD) places gamma at χ→0^(∘) and visible light at χ→90^(∘); near 90^(∘) the angle is acutely D-sensitive, so measuring the transverse angle of visible light against a lattice/anisotropy axis would pin D and test the picture. (ii) Dispersion: if instead gamma propagates as the transverse branch, the framework predicts a quadratic vacuum dispersion at a scale ≤882GeV—detection would confirm a transverse-lattice character of light, while continued non-detection favours the quasi-longitudinal reading and presses for its dynamical derivation.
