DESCRIPTION:There appear to be deep connections between geometry and entro
 py. This connection was first seen in black hole thermodynamics\, but has 
 been more fully realized in the Ryu-Takayanagi procedure for calculating e
 ntanglement entropies in AdS/CFT. We suggest that this connection is even 
 broader: entropy\, and in particular compression\, are the fundamental bui
 lding blocks of emergent geometry. We demonstrate how spatial geometry can
  be derived from the properties of a recursive compression algorithm for t
 he boundary CFT. We propose a general algorithm for constructing MERA-like
  tensor networks and elucidate connections to the mathematical field of in
 tegral geometry. We arrive at a new\, non-perturbative refinement of the s
 pacetime entanglement conjecture.
