the reader can draw his conclusions.

The questions is not whether N-stars are superfluid or not but is this “protecting” the n-star. Otto never got this.

I cannot agree such zero viscosity could prevent MBH capture — as zero viscosity is not a ‘get out of jail card’ once traversed by a (non-radiating) MBH event horizon…

Otto is asked for simething like that for years. He never delivered. Think about that.

The point is not the superfluidity’s existence as such, but the fact that superfluids are frictionless, as Kammerlingh-Onnes dicovered in 1911. They sneak through the finest cracks in bottles, not losing speed through friction, and defy gravity. A sufficiently small projectile therefore cannot get stuck inside them.

The high temperature of neutron stars’ cores is a conceptual barrier to believing this. And in fact the most modern models are quite complicated. Nevertheless it is a “safe bet” that micro black holes cannot grown inside their cores. They also cannot grow inside their (likewise superfluid) inner crust. But most likely in the outer crust they can. There, they become fattened a bit, to get heavy enough to fall into the uperfluid, to move inside on Keplerian orbits, sometimes touching from within on the crust to eat a bit and fall back, to eventually orbit inside and — perhaps — combine with sister holes there to form a more or less centrally moving “black core” inside. The presence or absenceof the latter may become analyzable from a detailed observation of the temporal structure of glitches.

Is this “unwashed” preliminary answer okay with you?
