Well, we know that black holes exist, they have been detected.

Errr no.

Err...yes:

Errr NO.

Errr No.

Err...yes.

Errr No.

All you have shown is a supermassive concentration of mass

....with all the characteristics of a black hole,

Err No.

Err, yes. A black hole is a mass with an escape velocity at
or above c.

which is nothing more or less than a mass with sufficient density to
establish an escape velocity at or above c.

You haven't proven the escape velocity is C.

It's in the definition.

Send me a pic of the frozen horizon, let me decide.

So you really don't know what the event horizon is, or you
wouldn't ask for a "pic". Tell you what, you send me a "pic"
of the Earth-Luna zero-G point, and I'll send you a "pic" of
the event horizon.

That's known as "confirmation".

Err, No. That's known as "probably a BH".

You *did* know that this is what a black
hole is, right?

I do, do you?

Apparently, since I stated it and you agreed.

Your next job
is to prove the mass sits *INSIDE* the horizon, and that
a horizon actually exists.

Since the horizon results from the mass it's difficult to
imagine where else the mass could be;

Do you have a pic of the horizon?

The horizon is the spherical locus of the distance from the
center at which escape velocity is exactly equal to c; how
would you suggest taking photos of it? For analogy, consider
the Earth-Luna zero-G plane, or the spherical shell at which
Earth escape velocity is, say, 1m/s. Take a "pic" of either
and post it.

does the mass of the Earth exist other than at the center
of the gravitational field of the Earth?.

Well, I know the mass of the moon is within the moons radius.

We have pics.

We have "pics" of the mass of the moon? Not the moon, but
its mass? Really? Cite, please.

But I'll note that, given the observed characteristics,

What characteristics?

Accretion disk, characteristics of the energy release of
infalling mass, etc.

plus the rather simple calculation for
escape velocity,

Schwarzchild's solution is anything but simple.

The basic calculation for escape velocity is simple:

Ve = sqrt(2GM/R)

You don't need Schwartzschild's solution unless you need to
address internal conditions, which aren't required for
calculating escape velocity.

the horizon not only exists for a
particular minimum density, it can't fail to exist.

Good, now wheres your proof?

Proof that the horizon must exist above a certain mass
density? See the equation above.
