Density scaling of accretion
The argument
Because linked claim, by six to fourteen orders of magnitude, and because in both the microscopic-capture and Bondi regimes analyzed by Giddings and Mangano the accretion rate rises steeply with ambient density even after allowing for the higher sound speeds of degenerate matter, any black hole that accretes on a hazardous timescale in Earth accretes far faster inside a white dwarf or neutron star.
Does it work?

Premises
- UnassessedNo current assessment. Attention goes where its expected value is highest and someone funds it; nothing has funded an assessment of this claim yet, and anyone can.constitution →White dwarf and neutron star interiors are vastly denser than terrestrial matter.

The inference goes through, but not on the density contrast alone: because Bondi-regime accretion scales inversely with the cube of the sound speed, and degenerate matter has very high sound speeds, the density premise linked claim needs the detailed regime-by-regime calculation of Giddings and Mangano to carry the conclusion. That premise is settled, so the argument's weight rests on the peer-reviewed calculation itself, which no published analysis contradicts and which the resolution of the Eddington objection now leaves unopposed.
