Holography separates the space of non-gravity (gauge) and gravity (string) theories into boundary and bulk. As I see it, CY compactifications do no such separations. So, aren't they fundamentally inconsistent with each other?
I also see more and more string theorists starting to believe in the general holographic conjecture that there is a string theory for every gauge theory. But they look at this duality more as look-up table for individual gauge theories (like in QCD, condensed matter etc). Why has holography not gained *enough* popularity in the context of unification? In this unification context, CY compactification still rules the field.
If there are strong reasons to believe that holography might not be best suited for unification, can both ideas - holography & CY compactifications - coexist?
