I think it is bad journalism, intended to boggle not enlighten.
The paper mentioned is http://arxiv.org/pdf/0912.0008 http://arxiv.org/pdf/0912.0008, and does not itself make mention of black holes.
Presumably the "higher-dimensional" aspect is coming from Hartnoll and Hofman's "large number of degrees of freedom" analysis.
I don't know anything about this area to guess whether there is really a black hole analogy.
But I am confident it isn't a useful analogy to make anything more clear!
- zokier 10y agoThat paper does not directly mention black holes, but holographic correspondence (which is even in the title!) does seem to have strong connection to black holes and higher dimensions, which is further spelled out in the references. As far as I can tell (which admittedly isn't much), the black hole connection goes deeper than just an analogy. Overall, I don't feel like Quantas short reference there is bad journalism, the subject matter being truly quite mind-boggling. Here is another article from the same reporter about this holographic stuff: https://www.quantamagazine.org/20130701-signs-of-a-stranger-deeper-side-to-natures-building-blocks/ https://www.quantamagazine.org/20130701-signs-of-a-stranger-...
