Field Theory to Spacetime

Abstract

The AdS/CFT claims an exact equivalence between certain theories of quantum gravity, defined in d+1 dimensions, and conformal field theories defined in d dimensions. Since quantum gravity is a fundamental theory of spacetime, the AdS/CFT correspondence is expected to provide deep insights into the most basic structure of space and time. At present the correspondence is a conjecture which has passed an impressive number of tests but remains somewhat mysterious. This article suggests a set of variables with which new features of the correspondence can be explored.
