Unless you watched the formation of the black hole, there is a limited amount of information you can know about the contents of a black hole, from the outside: It's total mass, net electric charge, and overall rotation (angular momentum).

It is thought that all matter is crushed into a singularity of infinite density at the center of a black hole, so it is doubtful that any bosons (or any other particle) falling into a black hole would retain their original identity or quantity.

Heh, bosons take no 'place' do they? :)

So, assuming that the center too takes no place? How many can there be?
Assuming that there is a measurable center, Can we now put more bosons there?

bosons account for mass?

Tricky that one :)

Bosons can have a rest mass, as helium4, or they can be mass less as 'photons'. It seems to depends on how one think there? I use the Pauli exclusion principle to divide them, taking 'place' (fermions) or not taking place (bosons). But then you have those 'bosons' taking place, as helium4?

"at sufficiently low temperatures (approximately 2K), helium-4 Bose-condenses and becomes a superfluid. Superfluids exhibit many strange properties including zero viscosity." Still, at room temperatures they definitely take a 'place'.

What would the temperature be near the center of a Black Hole?

what did the pressure cooker say to the black hole?

Just out of curiosity - I crunched some numbers for that figure of bosons.  Assuming the heaviest elementary boson - currently around 130 GeV - a black hole with that many bosons would have a mass of around 10 grams, be far and away the hottest thing around at 10^25 K, and evaporate in a splurge of gamma radiation and particles in 10^-23 of a second

lol not a very habitable place to be..

  this research might help out a lot on black holes..
