Hi Doc B.

Thanks for these answers. These concepts seem to pose further questions as in the 'then what?' category. There has been a posting while I type this one, but I see that this post still has discussion matter, so here goes.

That Warped Passages book is indeed requiring repeated readings. There are so many terms to remember. I cringe at the next steps: Learning the Greek alphabet and learning the math! of all these theories. But I fear I would require more minutes than there are molecules in the multiverse, to do this.

If only spacetime, free of any matter, remains around the event horizon, would this then be considered a naked singularity?

I too dislike infinity outside of pure mathematics. 'Phut' is as good a term as I can imagine for the singularity's eventual demise. The interesting concept for me when trying to visualise such a process is that time has stopped from the event horizon down to the singularity.

My understanding thus far about black holes is that time ....ends or is at zero, within the Swarzchild radius?

If this is so, whatever the singularity is up to, that process is almost infinitely slow to observers outside of the radius. It could well be the biggest boom ever, but at such a slow rate of time, perhaps a 'phut', even, might be wishful thinking?

Whatever the final light show, some piece of spacetime and energy which had been excluded from the 4 dimensional universe while it remained inside the radius, will now try to reintegrate with the rest of spacetime?

The other aspect I like to ponder is that final process for the singularity. Its naked and its now beginning to decay.

It may get to ... infinity somewhere in the process of becoming infinitely dense, but it is theorised as then beginning to decay, eventually? How can something come back from infinity?

On its way to infinite density, matter and energy will get squeezed. That suggests increase in temperature during some intital phase in the making of the singularity? There are more and more atomic collisions, which would generate heat from friction?

At some moment, extremely low or zero atomic movement will then rapidly cool the singularity to smaller volumes? This is where some form of heat radiation would have to be emitted?

Add pressure and the atoms are bound into one big system. Add more pressure and the nuclei pop into quark soup. Add more pressure ..... then what?

My gut feeling is that something goes ballistic somewhere. But being that time is at zero, from our viewpoint, what could we observe?

Getting back to 'infinite' density. If such an infinity were to 'blow', would this not be a new 'Big Bang'? It would be a comparable bang but occurring within an existing spacetime and multiverse, which are not necessarily the medium which hosted our 'Big Bang'? It would blow when the singularity squeezed smaller than the 'string' scale of spacetime itself? The bang would nevertheless only be proportional to the size of the singularity's accumulated mass? But any mass would do strange things at ....infinite density? The thought of a huge black hole with trillions of solar masses in digestibles going to infinite density .... Ouch!

Cheers.
