If supermassive black holes exist, can this mean that hypermassive

>>8872887
fuck it, sure why not

My guess is they don't exist yet, because it would take supermassive black holes a very, very long time to accrete that much matter.

The largest galaxy we know of is 100 trillion solar masses, the Milky Way is only around 1 trillion solar masses, so I'm guessing the creation of hypermassive black holes would probably be omens of a dying universe.

Although technically if we just float eternally in space in one direction we will eventually stumble upon one.

are event horizons perfect circles?

>>8872887
I would guess not. As it's assumed that our universe is uniformly dens on a large scale, and supermassive black holes are not commun as is, it would be highly unlikely that a black hole of that magnitude exist.
What about very ancient black holes then you may ask, that could have formed in the early universe.
Well even if they formed, the Hawking radiation has already done a number on them.

Not if the black hole is rotating.

Possibly the last black hole, i.e. if the last black he's in the universe, after having merged with other supermassive black holes, merge before dissipating. The expansion of space at that point May render that impossible though.

Black-Hole cant rotate :

>Speed in a BH...
>Time in a BH...

They're more of a spectrum than anything

Pretty much this, but denser regions of galaxies could move ahead a little quicker on that

>>8872887
We live inside one

Brainlet here, I'm p sure that blackholes have a maximum stable limit.
