High-energy observations of photons originating from gamma-ray bursts indicate that spacetime is continuous at the Planck temperature, which is on the order of the temperature near a bounce.
“Finally, we note that the high-energy observations of photons originating from gamma-ray bursts indicate that specatime is continuous at the Planck temperature (Vasileiou et al. 2015), which is on the order of the temperature near a bounce.”

The Abstract (page unavailable) reports that high-energy photons from GRB090510 place a Planck-scale limit on a model of stochastic photon-speed variation. It does not conclude that spacetime is continuous at the Planck temperature; it discusses Planck energy and length, not temperature. The comparison with a bounce is likewise not addressed in the cited paper. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
