That seems like a weird condition. "Average density" is pretty well-defined and doesn't need even spreading.
Even more, isn't the distribution of mass within a black hole a meaningless question? There's no information coming from the black hole, for an external observer it literally doesn't matter how the matter is arranged within.
- lumost 3y agoThis assumes the mass forms a perfect sphere with no thermal oscillations or other deformities.
- The_Colonel 3y agoWhat claim needs an assumption of being perfectly spherical? A rotating (or merging) black hole can be deformed (non-spherical), but that doesn't stop you to calculate average density.
- lumost 3y agoMy comment was on the the innards of the black hole as a meaningless topic. The event horizon (if observable) is likely to have an immense amount of detail on the geometry and mass distribution inside the event horizon.
