AdS_5 and the 4D Cosmological Constant

High Energy Physics - Theory 2009-10-31 v3

Abstract

The hypothesis is discussed that our universe is really 5--dimensional with a nonzero cosmological constant that produces a large negative curvature. In this scenario, the observable flat 4--dimensional universe is identified with the holographic projection of the 5--dimensional world onto its own boundary.
