CHAPTER

The Quantum Gravity Side of the Duality Is Quanti Mechanical

In practice, when you really want a full description of the theory, you start with the c f t and you derive the quantum gravity side from it as an emergent holographic phenomenon. Because the quanto gravity side has one more dimension of space time than the a conformal field theory side does. And i'm not even sure that the gravity side by itself has a full rigorous description. So i'm not quite sure this really is a duality. I don't see any possible way that you could get quanti mechanics to emerge from space time. Space time is classical. You're not going to get quanta Mechanics to emerge from that, as far as i could tell. That
