The issue here is not as simple as it seems from your comment. An early conclusion drawn from GR is that there would be a point where the "force" of gravitation would overcome all other forces and the mass would colapse into a "point singularity", a large mass with zero dimensions, defined at the time as a black hole (or included in the description). There aren't too many serious physicists that belive what we now call black holes, based on cosmological observations, are point singularities. A point singularity is not consistent with QM.., but for all intents and purposes GR also has significant real world issues associated with the concept of point singularities. I have not read the paper that got this thread going, but from the discussion it seems that it was a theoretical paper, once again exploring the theoretical implications of point singularities. The comclusion seems to be that they cannot exist. That is point singularities cannot exist. That got hyped by press and bystander commentary to mean that for QM, black holes cannot exist in any physical form. I don't believe that is true. I do agree that it is likely that point singularities do not exist.
