Interesting report and 7:57 video too. "Breaking down the AdS/CFT correspondence. Like, what IS it?"
My observation - is AdS/CFT using the cosmological constant again? The article gives me this impression apparently using a negative cosmological constant. The cosmological constant was a problem, negative, zero, or positive values arrive at different universes and ours is apparently finely tuned physics allowing life to exist here. See Relativity The Special and the General Theory by Albert Einstein, 1961, p.133-134. As the space.com article says, "So, on one side of the AdS/CFT correspondence, you have a universe that doesn't look like ours, and on the other, you have mathematical theory that doesn't apply to most situations. So what's the big deal?"
Yesterday morning at 0853 UT or 0453 EDT, I enjoyed telescope views of an Io shadow transit at Jupiter. Apply ADS/CFT and string theory with at least 5 dimensions here. This could be an interesting model to predict Galilean moon events at Jupiter or perhaps, *that doesn't apply to most situations.*
