Surprised that you didn't mention the possibility of a mirror matter black hole, which might be unreactive with normal matter, although at that level of extreme density - it is anyone's guess as to whether everything becomes cosmic mush.
Hey - since we are walking on the wild-side anyway: Also the further possibility that the destructive ability of micro black holes, if they can exist at all (I think not) but if they can - that these can be effectively "neutralized" by small amounts of mirror matter which would accumulate due to gravity, but possibly form a dense surface shell - rather than be 'consumed', thus offering some 'protection' <g>. ----- Original Message ---- From: Horace Heffner Suppose we actually have microscopic black holes in the center of the moon, or earth for that matter. They would tend to be maintained at the center of gravity. Their matter consumption rate would depend on relative motion with that matter, and their cross section for consumption would be very small. Even in a liquid core environment, the rate of matter consumption would eventually depend primarily on the viscosity of the core matter. The rate of consumption would be finite and for a very long time possibly exponential. In a solid core body like the moon, the consumption might never occur, because the black hole would essentially hollow out a vacuum around itself. If black holes can carry charge, then it may be feasible for them to form negative "atoms" in which they are the nuclei, and ordinary atomic nuclei act like electrons. Such atoms would be insulated from further accretion by electromagnetic action of the satellite nuclei on surrounding matter. Even purely by the force of gravity and by quantum constraints, a gravitation force atom might be feasible having nuclei for satellites. If sufficient delay can be obtained, then the black hole will evaporate. If the force of the black hole's gravity ever exceeds the EM force, at a macro distance, then the ball game is probably all over for the host body.
