First some context: we currently don’t have any physics theory that predicts the gravitational field of a particle in a superposition. This isn’t due to a lack of ideas for theories, but in large part because the predicted effects are much too small to run experiments, for at least a few more decades. The paper is about a simulation based one candidate theory for such a gravitational field. The interesting result is that the simulation yields a range of black hole masses predicted by the theory, even though the authors didn’t specifically plug that assumption in. This could be an argument in support of the theory. (But could also be a coincidence, or stem from some underlying math that the researchers didn’t think about, that also underlies the mass prediction, which would mean the result is a tautology.)
