#3Potentially a testable hypothesis for string theory? I.e. that it might predict something observable that isn’t accounted for otherwise?

#4> Black holes, the densest objects in the universe
My mind was blown when I found out that mean density of black holes inside the event horizon can be quite low.

#5> One question that’s still unresolved is whether the supermaze versions of fuzzballs fully satisfy all the requirements scientists have for black holes
The only question about supermaze fuzzballs blackholes, still unresolved, is what do string theorist smoke these days.

#7seems pretty safe at this point to not care what string theorists have to say about anything, unless they’re paying for dinner?

No, still no.

This is purely based on the definition of "density" here, which is the mass of the black hole divided by the volume inside the event horizon (which is the invisible/black sphere).
However the event horizon does not represent the extent of the mass of the black hole, but rather the point where gravity becomes so strong that nothing can escape it, even light (hence "black" hole/sphere).
We don't really know what's inside the event horizon or how the mass if actually distributed. The concept of singularity is that all the mass is located in a zero volume with infinite density.

You are asking too much.
