What if the singularity was a type of ultra mini star that exploded?
Planets and stars have layers, Do black holes must have layers as well?
Are black holes central cores pushing out Hawking Radiation, or are the poles doing it?
Black holes have magnetic fields widely distorted, could it be possible to tell how many layers a black holes has by reading its magnetic fields?

Will get back to this. In summary.

- can happen
- yes, we discussed this a couple of years ago.
- the event horizon
- yes
I suspect no-one else does either.

That is one theoretical mechanism for creation.
There are three layers – The event horizon (which is just a virtual line in the sand), the space on the inside of the event horizon, and the singularity at the centre.
Hawking theorised a mechanism whereby radiation would be emitted by the event horizon, and observation confirmed its existance.
I don’t understand the question.
It’s not clear there was ever a singularity so the question assumes facts not in evidence.

I think in this context it would be reasonable to interpret “singularity” as “whatever the state of matter was at the start of the process known as The Big Bang”.

Good article.
I’m sure that’s not the first time it’s been said, but that’s the first time I’ve read of proper scientists saying the start of the big bang could not have been a singularity (as opposed to might not have been).

“There are even some very famous graphics put out by top cosmologists that illustrate this picture. But that doesn’t mean this is right.”
I relieved to know that I’m not the only person ignorant of the fact that a singularity appears to be a non-starter.

Dear Dark Orange, you are forgetting firstly that black holes have charge and spin. A black hole with charge and spin has multiple layers, an inner event horizon, an outer event horizon and an ergosphere for starters.
In addition to the familiar two methods of creation – creation by collapse of stars and creation by collision – there are at least two others. One is outside the scope of this thread. The final one is mini-black holes with a mass of order 1 kg. The mini-black holes also go by the name of primordial black holes and are created in the earliest moments of the universe.
The Hawking radiation originates at an event horizon. It is radiated both outwards and inwards from the event horizon.
By measuring the magnetic fields of a black hole, you not only find the spin axis but also the rate of spin and electric charge. The mass, rate of spin and electric charge together tell us how many layers a black hole has.
