PUH Theorem 385 — The Double Pulsar Tests PUH's Own Tension Waves: T193's Two Patterns Match When Fed Equally by the Stars' Motion and the Lattice Stretched Between Them, and All the Mass Radiates

Photonic Universe Hypothesis (PUH) — Theorem paper. THE QUESTION. T384 found that the tension, carried with the matter that makes it, gives frame dragging and the double pulsar's periastron advance, and left open propagation: gravitational waves and orbital decay (T383's OPEN (3)). The archive already says what a gravitational wave is. T193's Theorem 5 makes it a wave of lattice tension with two transverse patterns (plus and cross), running at the lattice's phase-mode speed and sourced by the vortices' energy. T292 calls it an oscillation of the tension in the spin-2 direction. T237 makes the Planck core its effectively sole source. The GW Bow Wave Lead Note has the orbit stress the lattice, with an excess (v/c)^alpha along the orbit's axis. T207 allows extra modes like P- and S-waves. The double pulsar (1.338185 and 1.248868 solar masses, 2.45-hour orbit, shrinking 7.15 mm a day) agrees with the quadrupole formula to 1.3e-4 (95 per cent; Kramer et al. 2021), and it tests each claim. RESULT 385.1 — T193'S WAVES NEED THE LATTICE STRETCHED BETWEEN THE STARS. Fed by the stars' motion alone, T193's two patterns carry 0.25118 of the measured loss. The stars do not coast: the lattice between them pulls them round, as a tension G mA mB/d along the line joining them, and that tension swings round with the orbit. Counted as a source, it brings the share to exactly 1 (identity checked to 3.9e-16); in a circular orbit the stretched lattice and the motion each supply half of every wave's amplitude. T292's wave read as one number per point (T383) carries 0.16673 alone and 1.16673 on top of T193's patterns, 6,410 and 1,283 times the measured precision away. T193's Theorem 5 is confirmed with its source made explicit; the tension's one-number part must not ripple with gravity's strength. RESULT 385.2 — ALL THE MASS RADIATES. If only the cores radiated (T237's genesis half; T367: cores at most 0.3 solar masses, seeds 8e-4), the orbit would decay at 0.05405 or 3.843e-7 of the measured rate. What pulls is what radiates. RESULT 385.3 — WHERE THE LATTICE'S OWN TENSION COUNTS. Not in the static pull: T344's flux law as filed, with T299's metric, gives Mercury 42.98 arcseconds per century; adding the lattice's own energy gives 35.82 or 50.14. In motion, the stress of T344's sigma field integrated over all space is a pure tension G m1 m2/d along the line between two bodies (-1.00000000 along, 0.00000000 across): the stretched lattice. RESULT 385.4 — THE ARCHIVE'S ADDITIONS, BOUNDED. The Bow Wave Lead Note's excess with alpha = 1 would raise the double pulsar's loss by 1.09e-3 to 2.08e-3, 8 to 16 times the precision. It needs alpha >= 1.31 to 1.40 (1.46 to 1.56 with the relative speed), or no net gain. T207's extra modes, read as T235's acoustic modes (helicity 0 and +-1, no response in a flat detector from overhead), must couple to matter below 0.0279 and 0.0228 of gravity's strength. RESULT 385.5 — HOW FAST THE TENSION WAVES RUN. On T320's lattice (sum (k.alpha)^4 = 36|k|^4 over the 240 roots) the group speed is 1 - 0.0750 (ka)^2, never above c. With the lattice unit at the Planck length the waves fall short of c by 4.4e-94 at the double pulsar's frequency and 8.6e-83 at 100 Hz — more than sixty orders inside GW170817's window of -3e-15 to +7e-16. NOT CLAIMED: that PUH's field equation is derived (T298); what in the lattice makes its own tension a source; the strong-field form of the waves; anything about the core's Shell. KILL-CONDITIONS: a binary whose decay departs from the quadrupole value of T193's equation, or follows its cores' masses rather than its stars'; a confirmed scalar or vector polarisation coupled at more than a few per cent of gravity's strength; gravitational waves arriving at a speed different from light's beyond the lattice's (ka)^2 shortfall; a bow-wave excess with alpha below 1.3 in a binary moving at about a thousandth of c. OPEN: the lattice mechanism that makes its own tension a source and keeps the one-number part still; the carrier of the tension's rest frame (T384 OPEN (1)), now also carrying the waves; PUH's field equation (T298, T301, T329).
