The preprint of the paper that is the subject of the (not so great) phys.org article at the top is <https://arxiv.org/abs/2205.08767>. An accessible HTML5 version is available at <https://ar5iv.org/abs/2205.08767> (arxiv->ar5iv, the latter expands to a link within ar5iv.labs.arxiv.org). Hawking radiation is a semiclassical result: the curved spacetime is classical General Relativity and the scalar field (in which Hawking quanta arise near the central black hole) is quantum. The dynamical spacetime creates -- through the equivalence principle -- an acceleration between past observers and…
