DIsagreement is optional and fattening
In the same way, there’s no simple way to tell if the world we see around us is an illusion, a collective hallucination or the real 3D deal.
This is retarded. There is nothing more real than the real, so by definition this is the real, whether you find a complex mathematical mapping of some lower-dimensional space onto a "pseudo" 4-D space or not and declare that lower-dimensional space to be "the real thing".
Btw. here is a discussion of the announcement from a couple of years back:
where we also read:
But some experts on the holographic principle think the experiment is completely off-target. “There is no relationship between the argument [Hogan] is making and the holographic principle,” Bousso says. “None whatsoever. Zero.” The problem lies not in Hogan’s interpretation of the uncertainty relationship, but rather in “the first step of his analysis,” Bousso contends.
Bousso notes that a premise of special relativity called Lorentz invariance says the rules of physics should be the same for all observers, regardless of how they are moving relative to one another. The holographic principle maintains Lorentz invariance, Bousso says. But Hogan’s uncertainty formula does not, he argues: An observer standing in the lab and another zipping past would not agree on how much an interferometer’s beam splitter jitters. So Hogan’s uncertainty relationship cannot follow from the holographic principle, Bousso argues.
