The Milky Way — the missing-mass gap, and the wave field that fills it

From the observed velocity gap to the BeeTheory prediction, recomputed on real Gaia data

Result first

Applying the same wave mechanism that yields Newton at Solar-System scale, with the visible mass resolved into its components, reproduces the Milky Way rotation curve. Recomputed fit on real Gaia data (Ou et al. 2024): λ = 2.89, c = 0.89, ℓ_floor = 3.0 kpc, χ²/dof = 0.33. No separate dark matter — the wave field of the visible matter fills the gap.

1. The problem — the velocity gap

The points are the real measured rotation velocities (Gaia / Ou 2024). The blue curve is what all the visible matter — bulge, thin and thick disk, gas — can produce by Newton alone. It rises, peaks near 5 kpc, then falls. The observed velocity does not fall: the shaded region is the gap that visible matter cannot explain.

Observed velocity (red points, Gaia) vs the velocity from visible matter alone (blue). The gap widens with radius — from +31 km/s at 4 kpc to +91 km/s at 20 kpc.

2. The reasoning — a one-way chain

BeeTheory adds no new matter. Each visible component projects a wave field; the calculation flows in a single direction, from photometry to the predicted curve, never backward:

photometry → baryonic decomposition (ρbar)
  ↓
wave kernel convolution → wave density (ρwave)
  ↓
mass integration → enclosed wave mass Mwave(<R)
  ↓
Newtonian relation → predicted curve Vc(R)

Each component is integrated according to its own geometry — the bulge as a 3D sphere, each disk as a 2D ring — then the enclosed wave mass gives the velocity:

Mwave(<r) = λ·Mvis·[1 − (1 + x + x²/2)e−x],  x = r/ℓ,  ℓ = c·Rd + ℓfloor
V²(R) = V²baryon(R) + G·Mwave(<R)/R

The four Milky Way components (thin disk 4.0×10¹⁰, thick disk 6×10⁹, gas 1.0×10¹⁰, bulge 1.0×10¹⁰ M☉) each contribute their own enclosed wave mass; their sum is the total wave term.

3. The result — the wave field fills the gap

The orange dashed curve is the wave term Vwave. It is small at the centre (where visible matter suffices) and grows outward — exactly where the gap opens. The green curve Vtotal = √(V²baryon + V²wave) tracks the Gaia points across the whole range.

Reading & honesty

The points are real Gaia measurements; the curves are recomputed here, not reused from memory. The wave term grows from ~97 km/s at 4 kpc to ~170 km/s beyond 16 kpc, precisely covering the shaded gap of the first figure. Two honest caveats: (i) the baryonic component masses are the standard Milky Way values, not a SPARC measurement (our Galaxy is not in SPARC); (ii) λ and c are fitted to this curve, not yet derived from the wave function — the empirical match is strong, the first-principles derivation of these parameters remains open.
