It fits in most beautifully.
It fits in most beautifully. The question is, however, what that fifth dimension is. In standard AdS/CFT, the fifth dimension is the scaling dimension. As you move towards positive and negative infinity you move between the UV and IR fixed points. I have thought a lot about how this might fit in with my own ideas about 5D spacetime theory where the fifth dimension is more like a temporal dimension. Does the theory predict a flip between AdS and dS as some researchers propose? I find this more appealing than finding dS/CFT. But you have to explain why the cosmological constant is negative at small scales and positive at large.
