Ok, so if I understand correctly, AdS spaces aren't meant to directly model the universe, but rather are used as a tool to make certain calculations in CFT easier?
GP's comment was modelling the universe as AdS/CFT, though, which is why my question addressed precisely that part:
How is AdS/CFT (as it pertains to describing spacetime & the Standard Model)
Sorry, my point was to (almost facetiously) interject the topological concept of "boundary/bulk" correspondence (as also exists with holograms & AdS/CFT) rather than suggesting the correctness of AdS/CFT.
The idea that "outside" becomes available via a change in perspective from boundary to bulk.
