@ Tom Marking:

So in other words, no direct physical evidence for the concept.

Oh, there is direct physical evidence ot there such as accretion disks and their radiation without any central stars. But not every astronomer is convinced, I hear.

What does the angular momentum of a mathematical point mean?

I already explained in another comment, spin applies to pointlike particles.

You can derive spin and angular momentum by looking at the objects response to disturbances in its environment, such as when NMR is used.

In the standard blackhole model what is the only entity containing the mass?

The mass et cetera is defined by its imprint far from the object. It isn’t localized.

In the standard blackhole model what is the only entity containing the mass? Is it not the singularity? And is not the singularity behind the event horizon? What happens to the gravitational field lines leaving the singularity? If they cannot make it through the event horizon then no mass outside the event horizon can sense the blackhole’s gravitational field. It seems to me that the gravitational field line propagates from inside the event horizon to outside it.

Tom Marking: That all encompassing store of Humanity’s knowledge (Wikipedia) tells me that the singularity in BH with angular momentum atually forms a disk, not a point. (It still has no volume, since it’s 2 dimensional.)

Io reiterate, I wish I’d done the research before posting.

that was a gAstley thing to do.

Oh, what sad times are these when passing ruffians can rickroll at will to old ladies. There is a pestilence upon this land, nothing is sacred.

“It is true that events within the event horizon cannot propagate out to us. However, that does not necessarily mean there is no data external to the event horizon that will tell us what type of object it is under the event horizon.”

If this were true, changes behind the event horizon would be observable as changes outside the event horizon. In other words, it could be used to send signals accross the horizon. This is why black holes “have no hair”.

It seems you have dismissed occam’s comic as being an electric universe proponent but it seems he is suggesting he is not. The question remains, is his point correct? Would is be called a plasma seeing as it is in this magnetic field presence, at these temperatures ?

I ask, because I am confused as to why you are dismissing his claim so readily, by suggesting he is from some pseudo-scientific back-round, when it seems that what he says about the presence of the magnetic field playing a part makes a lot of sense. Is it a ‘gas’ generally speaking, or more specifically, would it be a ‘plasma’ ?

Confused.
