"In the AdS/CFT correspondence Maldacena showed that one can completely describe a black hole purely by describing what happens on its surface. In other words, the physics of the inside—the 3-D “bulk”—corresponds perfectly to the physics of the outside—the 2-D “boundary.”"
Very interesting!
I thought quantized spacetime had already been disproven below a testable range? I.e. Any theorized particles wouldn't be seen by particle accelerators smaller than say a solar system or drastically larger.
I always thought of Einstein's theory of General Relativity as a model. For me it doesn't explain the execution.
This to me makes more sense that at a quantum level there are discreet particles that are being acted on according to relativity. I think of it more like a CPU where this is a clock input.
Scientific American has turned into such a rag... their recent bit about "entangled black holes" was especially cringy.
It's Michio Kaku level of hand wavery and lack of rigor.
