DESCRIPTION:There appear to be deep connections between geomet
ry and entropy. This connection was first seen in
black hole thermodynamics\, but has been more full
y realized in the Ryu-Takayanagi procedure for cal
culating entanglement entropies in AdS/CFT. We sug
gest that this connection is even broader: entropy
\, and in particular compression\, are the fundame
ntal building blocks of emergent geometry. We demo
nstrate how spatial geometry can be derived from t
he properties of a recursive compression algorithm
for the boundary CFT. We propose a general algori
thm for constructing MERA-like tensor networks and
elucidate connections to the mathematical field o
f integral geometry. We arrive at a new\, non-pert
urbative refinement of the spacetime entanglement
conjecture.
