astrophysics - Is it possible that black holes are also neutron stars?

Are there regions of space from which no light can escape (trapping horizons)?: almost certainly. Supermassive black holes can have large horizons, with surprisingly small space-time curvature, and we understand gravity and GR well enough that we can be reasonably sure that such horizons exist. Are there singularities inside these horizons? - almost certainly not. Physicists dislike singularities, which is one reason why they search for a quantum theory of gravity. So the question of what lies inside a black hole can only be answered when someone comes up with a consistent quantum theory of gravity.

Black Holes May Be Covered in Vortex Structures According to New Study


John Coffey:
Anything that approaches infinity tends to be a problem scientifically and maybe mathematically.  I have long suspected that matter might have a maximum density, making Black Holes not a point with infinite density but a tiny sphere.  It seems plausible since our mathematics tends to break down when discussing singularities.

Perhaps Black Holes could spin so much, or have a high enough energy that these would counter the collapse?  Maybe the time dilation becomes so great that it never becomes a point?

I am wondering if this is something that can be proved one way or the other using observations?

It might become 'solid' at the point where the gluons are pressed into the quarks, shoving all these particles into a TRUE solid, where the particles are totally crushed together and no space at all remains.  I don't believe we could simulate that, because the energy required to compress quarks and gluons in such a way would be beyond our capacity to generate.

John Coffey:
 @Alondro77  We know that subatomic particles are fluctuations in Quantum Fields.  Although we haven't defined a limit to the amount of energy that a Quantum Field can have at any particular point, it seems to me that there could be a limit where either it is not possible, or the field breaks, or it changes into something else.  
I don't think that we know what the fields are made of and probably will never know, but there might be properties at higher energy levels or densities that we will never be able to test.

🔢 How to count to 10 in Latin


I find this interesting because the numbers 1 to 6 are close to Spanish numbers.

The numbers 7 to 10 resemble our months 9 to 12.  This made me speculate that maybe the ancient Romans only had a 10-month calendar, although this was cited only in legend and the Roman Republic adopted a different 12.5-month calendar.  Later reforms would be done by Julius Ceaser and August Ceasar, from whose names we get July and August.

Re: Watch "You're Immortal And I Can Prove It" on YouTube

I like the video.  It doesn't teach me anything new, but he makes entertaining videos.
