Excellent. It's way past time.
NTP research never should have been stopped in the first place.

Yeah, that's why your theory sucks as much as the current one.
Mythical one time event that magically created the world.
No wonder it was presented by a priest.

If we are in a Big Rip scenario, perhaps once there is no heat differential anywhere, a quantum fluctuation will allow the creation of another universe. Or, perhaps more in the spirit of your post, we are in a black hole from another universe, and that is the end of it all.

How would there be one super black hole when galaxies are moving away from each other faster than light?

I've read that if the cosmos is infinite this could include it being infinite in the time dimension, meaning there's no starting point. This is a weird concept that challenges my thinking about what time means.

I guess I am confused. If you add an arbitrary number of dimensions, are you not adding additional degrees of freedom? And if yes, then is it surprising you can get an infinite number of shapes?
Also, I did not buy the quote, "if it spins too fast, it will break apart". Huh? I'm sure there is mathematical justification for that statement. But physical justification? Everything is within the event horizon. Where would it break apart to without falling back in?
I trust Quanta, generally, as a source. So I am sure their results are valid. Just explained very poorly. (Or so complicated no one can make an analogy for layfolks).

They know it but they seem to be forgetting that they know it. I think that they are waaaay out on a limb claiming to know the shape of what they cannot see. They know what is happening around it to a degree but they are assuming that what they "See" is an accurate representation of what "Is". My opinion is that their extrapolations that some black holes are in the shape of a birthday hat are likely a bridge too far. I may not be an "expert" but I call Shenanigans.

They're not going to find any dark matter. The concept is broken from the outset.

Reply to comment by Novve in Galileo High Accuracy Service (HAS) is now available! Galileo HAS increases the accuracy of Galileo to sub-meter levels. It will strengthen sectors where precise navigation is key, like agriculture or drones, also boosting innovation. by EU4Space
I belive it's automatic, but will work better if your smartphone, device or car have the latest software/ firmware update. So the chip manufacturer enable it through that approach, if hardware specifications are met.

“We can’t see black holes”
That was a whole lot of qualifiers just to say something everyone knows lmao.

Hi. Thanks. The answer of non - 3 D symmetry could be quite wrong, under a few circumstances:
(1) Enforced symmetries due to Standard Model extensions to black and white holes
(2) And [ very similar if not the same ] the outcome of General Relativity for rotating black holes [ or white holes ].
The questions about how to account for rotational momentum for the Standard Model when merged with General Relativity singularities is something that probably should be left to expert mathematicians. { : < }

I do like this answer better than my own. So the black hole is reacting to the distribution of the mass of matter around it. That makes sense. I also said round rather than spherical.

When you look in the direction of a really hot grill on a sunny day and look at something beyond it. The visual appearance of the things beyond it are hazy because the rising heat distorts the visible appearance of things beyond it.
I'm just going to out and out hypothesize, without a whit of training in Physics or anything related to space, that what is going on is that since we don't actually see black holes. we only see things around them, that our perspective on them is probably distorted. I cannot fathom how it would not be round.

Just a very brief thought.
Not sure if the author means "spherical" vs round [ in other words, symmetric in 2 dimensions ]
Probably spherical [ symmetric in 3 dimensions ].
The event horizon has to be non - symmetric [ imho ] since attraction of mass occurs in a non - symmetric space and with a non - symmetric distribution of matter.
Galaxies [ where many black holes occur ] are non -symmetric by mass distribution. [ another poster is welcome to differ, however ]
