P2 is the lead theoretical result: under its stated matter-contraction assumptions, it derives fNL = -35/16 = -2.1875. A future non-Gaussianity measurement can test that conditional prediction; no current survey measure…
A model-dependent ALP field-evolution calculation motivates a β value near 0.27°. Existing birefringence measurements have systematic and model-dependence questions and do not validate a bounce scenario.
A historic simplified comparison placed a matter-bounce slope near an external free-spectrum estimate under specific modeling choices. It cannot identify the origin of the signal or establish a bounce.
The quintom bounce unifies the bounce with dark energy through phantom fields. It predicts the dark energy equation of state w(z) crosses −1 (quintom-B behavior). The DESI DR2 BAO + supernova combination from external gr…
