Which Comes First: Galaxy or Black Hole?

"Do galaxies form first and then a black hole springs up in the
center, or possibly, do galaxies form around an already existing black
hole?"

“The implication is that the black holes started growing first.”

So, where does the matter come from that forms around the black hole
and creates the galaxy? Does it just condense out of energy? Does
the black hole somehow stress space to cause it to condense into
matter? Or does it just gather it from the extremely sparse
intergalactic void?

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Big Bang, Maybe?

**I don't think so.

Consider a donut.

First the donut, then the hole.

The age old chicken or egg thing, of whichever came first doesn't
really matter to 99.9999% of humanity or any part of our terrestrial
environment.

I favor that it takes a pair of black holes to start the process of
creating a star. Therefore, the cosmic molecular stuff and perhaps
then black holes have to exist first.

It doesn't really matter, GoofBall, you have a 50/50 chance of getting it
right
with your first irrational wild guess.

So, as per usual, you're not about to let any idea suggestion go
untrashed.

Double A No need to have come first,nor last. The BH was formed from a
very dense massive star it imploded more than it exploded. It left a
hole in space that long lasting stars could if lucky find a safe orbit
or others that could not and spiralled around until they fell in to make
the BH more powerful to capture still more stars. We see this galaxy
core (hub) so clearly. A spiral galaxy looks like a fried sunny side up
egg. TreBert

Or, black holes could simply be positrons (aka antimatter).

But there seems to be a constant ratio between the mass of a galactic
black hole and the mass of the galaxy. In extremely young galaxies
(ones that we are seeing when they were young at the edge of the
universe), the mass of the black holes seems to be disproportionately
large compared to the mass of the galaxy. This suggests that the
black hole was there first and the galaxy mass catches up later. But
the quesiton is, where does the mass come from that builds up the
galaxy?
