So now the analogy with classical thermodynamics seems clearer: just as fluids at our scale appear as continuous materials despite their consisting of a huge number of atoms, similarly, in quantum gravity, the fundamental constituent atoms of space form a sort of fluid, that is, continuous space-time. A continuous and homogenous geometry (like that of a spherically symmetric black hole) can, as Pranzetti and colleagues suggest, be described as a condensate, which facilitates the underlying mathematical calculations, keeping in account an a priori infinite number of degrees of freedom .
"We were therefore able to use a more complete and richer model compared with what done in the past in LQG, and obtain a far more realistic and robust result", continues Pranzetti. "This allowed us to resolve several ambiguities afflicting previous calculations due to the comparison of these simplified LQG models with the results of semiclassical analysis, as carried out by Hawking and Bekenstein".
Another important aspect of Pranzetti and colleagues' study is that it proposes a concrete mechanism in support to the holographic hypothesis, whereby the three-dimensionality of black holes could be merely apparent: all their information could be contained on a two-dimensional surface, without having to investigate the structure of the inside (hence the link between entropy and surface area rather than volume).

The ring would be circulating so rapidly that centrifugal force would keep the ring from collapsing under gravity. The ring, in turn, acts like the Looking Glass of Alice. Anyone walking through the ring would not die, but could pass through the ring into an alternate universe.
Disorder is just lost information, so among its more profound implications is that the amount of information that can be stored in a region of space is determined by the area of a surface surrounding it and not, as one might expect, by the volume inside. This means that a black hole — and perhaps the universe itself — is like a hologram, in which three-dimensional information is encoded on a two-dimensional surface.
Physicists are still grappling with what that means for the universe.

Since there is no such thing as a hologram which naturally occurs, one can safely assume that regardless of what is meant when a scientist uses the term, a black hole cannot be a hologram, or holographic.
The physicists have enough trouble comprehending these things and so my 1.1l 80bhp brain has no chance.

Light refracted through vapour.
Not a projection in the least, and certainly not a bloody hologram.
Personally I like the theory that our Universe itself exists within a Black Hole and within the black holes we see exist other Universes , and on , and on ..... That ones a real head scratcher.

Someone on the Monkey Cage was talking about the potential infinity of this universe. They pointed out that it also extends sub-atomically and it's been stewing in my thoughts since. It's ironic that 'turtles all the way down' could sum up not just our universe, but possibly ones both outside and within this one...like your black hole idea.
There's also the notion of 'frothiness' and how this universe could be like a bubble in a space full of other 'bubbles' that also extends ever onwards towards infinity.
