That way your reader can decide for themselves whether they want to bother with either a PDF or HTML version, especially since the HTML views are still experimental and have occasional display issues across devices.

It doesn&amp;#x27;t use a lot of fancy math or derivations to justify holography. Mostly it uses basic concepts from undergraduate physics to show how the idea of holography is consistent and makes sense, despite it seeming incredibly counterintuitive at first glance. For instance, figure 3 shows how you can&amp;#x27;t hide a black hole behind another black hole, which has implications for how a 3D universe can be completely encoded in a 2D region. https://arxiv.org/html/hep-th/9409089v2&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/hep-th_9409089/"&gt;Paper and discussion history&lt;/a&gt;.

Interestingly, this feature of black holes that they allow you to see what is on the &amp;quot;far side&amp;quot; of the black hole as a result of gravitational lensing was one of the heuristics used by Leonard Susskind to propose the holographic principle in his famous paper, &amp;quot;The World As A Hologram&amp;quot; https://arxiv.org/abs/hep-th/9409089 Note especially Figure 2, Figure 3, Figure 4, used to justify that a two dimensional screen is enough to capture all the information. Obviously there is a lot more going on -- especially the black hole entropy formula which says that entropy growths with surface area…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/hep-th_9409089/"&gt;Paper and discussion history&lt;/a&gt;.

It will be assumed that the entropy is found on the horizon and that no more than one bit per Planck area can stored there. The only thing I stated incorrectly was planck cubed instead of square. https://journals.aps.org/rmp/abstract/10.1103/RevModPhys.74.... The metaphorical name of the principle (’t Hooft, 1993) originates here. In many situations, the covariant entropy bound dictates that all physics in a region of space is described by data that fit…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/hep-th_9409089/"&gt;Paper and discussion history&lt;/a&gt;.
