Is there a limit of black hole size?

## Is there a limit to black hole size?

The universe acceleratingly expands. Its mean temperature lowers due to the (universal/spatiotemporal) expansion.
If the expansion continues, we'll have Big Rip (we don't know that, but it's a data-based extrapolation).

Big Rip will tear spacetime itself, and make the mass–energy so dense, that an omniblackhole (everything being a black hole) will form.

Actually, the cyclic cosmology pre-Big-Bang state doesn't have to be an omniblackhole (infinite black hole). It might be an insanely massive primordial black hole.

Astrophysical (real, non-idealized, non-Penrosean) black holes have many components:

• the maximally degenerate spacetime torus (the singularity includes no spacetime, the Kerr ringularity has no mass)

• the disc of accretion

• the astrophysical jets

• the halo / surrounding particle and radiation haze

An omniblackhole (all the universe being a black hole) has only one constituent: the the maximally degenerate spacetime [here not a torus; thus either a uniform whole, or a foam like structure due to large scale degeneracy phenomena we don't know].

The omniblackhole (all the universe being a black hole) can be avoided.

It can be replaced with the sole/single primordial black hole, but in order for that to happen we have to:

1. define the most degenerate state of mass-energy... actually [probabilistic] configuration of alternative states of spacetime

The most degenerate thing possible, is degenerate spacetime. Specific particles cannot be expressed at the maximally degenerate state possible in the universe. It's a chromodynamic fluid = the maximally degenerate spacetime = probably the pre-Big-Bang state = probably the chromodynamic fluid torus in astrophysical (real) black holes.

Real = astrophysical = non-Penrosean black holes don't explode (we don't have data to support they explode as a whole) because they enlarge whilst they consume mass–energy. Each black hole (per different size) has a different "threshold pace of accretion", due to: 1. maximally degeneracy liquid inertia, 2. maximal degeneracy pressure is terminally degenerate. The universe doesn't have a state more degenerate than the maximally degenerate spacetime = chromodynamic fluid. That liquid as a whole is a particle = probabilistic foam of alternative configurations). If more pressure is applied to it: 1. it phase-transitions into gamma ray bursts if the black hole is not the pre-Big-Bang state, or 2: it bigbangs (verb: to explode as one of the cyclic big bangs; noncapitalized because the Big Bang is the proper name of our particular universal cycle origin/beginning.

The "sole primordial black hole" (which doesn't necessarily have to be the infinite omniblackhole) hypothesis, has as prerequisites that: 1. terminal degeneracy exists (thus spacetime cannot be more compressed than that state of spacetime (state of mass-energy), 2. more compression causes it to escape as gamma ray bursts (mainly from the astrophysical jets)... or the degenerate chromodynamic fluid is phase transitioned into a big bang (thus redefining the configuration of spacetime).

The nowadays cosmic inflation theory isn't based on something physical we know (it's made to match the data). Black holes are physical.

(Why miniscule black holes immediately evaporate? Astrophysical black holes have a data correction headroom behind the event horizon, and before the degenerate chromodynamic fluid torus. The data correction headroom doesn't have to be immediately after the event horizon [particularly in galactic black holes]. The data correction headroom of the black hole is similar to the Bose–Einstein condensate. The Bose–Einstein condensate [see: Lene Hau]: 1. slows light, 2. compactifies it. I don't call the black hole's data correction headroom a Bose–Einstein condensate, but it acts similarly. The slow and compactified mass–energy tunnels back in the degenerate chromodynamic fluid torus [it gets reabsorbed; miniscule black holes don't have a data correction headroom behind their event horizon, thus they minibang [they minibang: they decay into external particles (outside the event horizon); the verb to big bang on the other hand means to decay into internal particles (inside the event horizon)].)

## correction:

Gamma ray bursts form usually when black holes form in the first place (that's the basic guess).
