Is a black hole

A black hole is another axiom. Read my new post, if you want. I wrote about this.

For some reason, I do think our universe is a child contained within a
black hole residing in our parent universe. The implies that our
universe has many children of its own...

Black hole is outside spacetime (not a part of the spacetime manifold). The way it
manifests itself in the model is that as a point approaches a certain region, the
metric tensor there becomes arbitrarily large. So even if we knew what piece to
add to spacetime to "include" the black hole, the result would be a manifold
with a certain subset (the singular set) over which the metric could not be extended
smoothly (like y = 1/x cannot be extended smoothly over the origin x = 0).

In the Schwarzschild case, not only the geometry cannot be extended over
the black hole but also its smooth structure. I think its PL structure does
extend though as it only involves "pinching", like the vertex of a cone.

In the Kerr case, the black hole singular region does embed smoothly
(it's a circle) but the geometry of course does not extend over it.

Sure, it is only a part of the sick imagination of Shit's
followers.

Not true. A black hole includes the region inside its event horizon,
which is clearly part of the spacetime manifold.

You are talking about the singularity inside the black hole, not the
black hole itself. It is just the singularity that must be deleted from
the manifold.

The term "black hole" was invented to describe a region for which
anything that enters cannot ever come back out. That clearly applies to
the horizon and the region inside it.

absolutely, he is confused like a LGBTQ+. I don't know what happens in
that country, since this is basic math modelling stuff.

BH are both inside and outside the universe?
It has an inner volume jan...

If you say we do not know what is inside jan?
Is there energy that fell in to form it?
Is there not more gravity inside that
accelerates mater above the light speed
event horizon fall speed?

Let me clarify what a black hole is..

Here is the dumb version NASA released of a photo of a black hole:

https://twitter.com/Starmaker111/status/1120589330349584384/photo/2

and here is the smart version of the same photo that I the starmaker
enhanced sharper for you:

https://twitter.com/Starmaker111/status/1120589330349584384/photo/1

Now, instead of looking at the black hole center (not so black is it?)

look at towards the center outwards to the edge...

it is made up of...waves.

Ocean waves, gravitional waves, waves going out spreading out.

Those waves...can reach the earth
and maybe change the direction of the
magentic pole...change the direction of earth's climate, etc.

A black hole is simply...simply...

a whirlpool is space.

(nasa doesn't want you to see the waves) (so they blurred everything)

https://twitter.com/Starmaker111/status/1120589330349584384/photo/2

but the waves are there!
https://twitter.com/Starmaker111/status/1120589330349584384/photo/1

of course if the earth was closer it would get caught up in the
whirlpool fabric of space.

Yes, I meant just the singular set as "the black hole". This is non-standard usage.
Sorry to confuse everyone. Just keep in mind that I meant JUST the singularity
when I wrote "black hole" above. I'll stop using this convention because it's
confusing.

Say you are are far from some mass that doesn't meet the BH criteria. It's radiating
energy (light) in all directions, and you are watching. Any point on the surface of
that mass radiates light in all directions (cosine distribution, IIRC), but you have
instruments all around the mass. Now let us have matter continuously falling into
that luminous mass. .As more and more matter falls in, the light coming out at an
angle theta to the radial axis at some point can't get out, although light on the radial
axis can still get out. When that angle becomes zero, a BH comes into existence.

It's my understanding that it takes an infinite amount of time (on a distant observer's
clock) for that to happen. Isn't that correct?

It is, absolutely; and that, of course, means, that for a distant observer
(like us all) a black hole doesn't exist and never will.

Which leads to an interesting paradox of whether black holes can exist
in our observable universe, rather than only frozen "almost black holes".

Does that mean you sobered up from your continuous vodka binge long
enough that you finally understand gravitational time dilation and how
it would be infinite for a black hole? So you finally understand t' !=
t? Cool.

Now we watch to see how long (short) this period of sanity lasts before
the vodka makes a reappearance.

They tend to show up in strange places. Take a look at the spirals in
one of my experimental vector fields:

In other words, a whirlpool in space is no different than a whirlpool in the ocean.

Scientific definitions for whirlpool
whirlpool
[ wûrl'pool' ]
A rapidly rotating current of water or other liquid that sucks everything near it toward its center.

Either a space whirlpool or ocean water whirlpool...the principles are the same.

there are blackholes inside blackholes, potentially an infinite number of
blackholes inside a blackhole. I have the model.

Of course, gravitational dilation imagined by a bunch of
fanatic idiots affects black holes imagined by a bunch of
fanatic idiots. Very simple, stupid Mike. "After Infinite time",
however, means "never".

For us distant observers, I don't think it matters whether the mass is inside the EH or
plastered on a sphere just outside. The external field will be the same.

As I said above, it essentially DOES exist. All it requires is that enough matter be
in a sufficiently small space.

I doubt that very much :-)

If we could put him in orbit around a BH at r = 1.5*r_Sch, at the microsecond of
sanity, he will be sane forever, as far as we're concerned.

No, trash. Above you wrote that it will start existing after
infinite amount of time on a distant observer's (mine or
yours) clock. I. e. never.
That you don't understand what you write is rather ordinary

not true. Size doesn't matter below the event horizon. There are
potentially an infinite number of blackholes inside a blackhole.

True. I wonder if we had such an "almost black hole" with frozen mass
and added even more mass if the view of the previous mass changes.

The mass and, therefore, the external field would increase.

If he were in the 1.5*r_S orbit, the extra added mass would cause him to spiral in
and be spread over the surface in a nanometer-thick sheet. A fitted sheet and a
fitting end.

Or would he? I don't know. My head is hurting again.

For us distant observers it doesn't matter that there is no black hole
there, what is important is that GURUS HAVE SAID they are.
