A recent study underscores the dynamic nature of black holes and extends similar thermodynamic characteristics to Extremely Compact Objects, advancing our comprehension of their behavior in quantum gravity scenarios.
A paper titled "Universality of the thermodynamics of a quantum-mechanically radiating black hole departing from thermality," published in Physics Letters B highlights the importance of considering black holes as dynamical systems, where variations in their geometry during radiation emissions are critical to accurately describing their thermodynamic behavior.
The study also suggests that extremely compact objects (ECOs) share these thermodynamic properties with black holes, regardless of their event horizon status. The significance of this research lies in its contribution to the ongoing efforts to resolve the black hole information paradox, providing a more nuanced understanding of black hole thermodynamics in quantum gravity contexts...
One of the most important problems in contemporary theoretical physics is understanding what a black hole (BH) is. It is believed that classical general relativity implies that a BH is an object with a horizon, i.e. a limit surface beyond which no event can influence an external observer, and a singularity in its core, i.e. a point at which the presence of infinite implies that the laws of physics fail.
On the other hand, recent approaches, both classical and quantum, have shown that what we call BH could be an object without both horizons and singularities. Objects of this type are also called Extremely Compact Object (ECO), to distinguish them from the "traditional" concept of BH.

not sure about the “best” part.
The best of theoretical physics reflects the scope what the human mind is capable of imagining and reasoning. Philosophy at its core is imagination and reason. It is humbling and instructive to realize just how wrong it can be on occasion.
not sure about the scope, because it doesn’t take into account Divine revelation or angelic influence. But as to the second part: hear, hear.
All models, theories, and religions are wrong; a very small number are useful... sometimes. As simplifications, models must, by definition, leave important details out. The underlying math can have God-tier timeless truths though. 1 + 2 will always equal 3, before the universe existed, and will forever after. The mistake comes from thinking perfect math leads to perfect theories about the real world. Math, or anything else short of the total universe itself, cannot ever achieve that. When math hits one of its infinite infinities, it has gone off the rails as far as anything in the real world.

also sometimes refered to as naked Black Holes.
Yes. It is quite possible to deconstruct almost all observations, norms, practices and theories to the absurd. There are those who lead often very miserable and vapid lives, agonizing that there are no real truths and truth cannot be defined. Such people, otherwise known as Democrats will always be among us.
So does that mean Einstein was mistooken when he predicted black holes, or that the structures astrophysicists now are labeling (and studying) as black holes are not the same structures as “Big E” predicted?
I wonder if Neutrinos interact with extremely dense objects.
Is there any “space” left in a Black Hole? As in, are all atomic and sub-atomic matter "Particles" squished together, neutrons, protons, electrons and anything else, with no distance at all between any “Particles”? Would that be a solid or liquid if true? Perhaps Energy?
I used to like watching Sabine Hossenfelders videos on Youtube until she went envirowacko. I would think that someone with that kind of math skills should be able to disprove at least the carbon pollution part of the hoax on the back of a napkin over a beer.
