Holography in AdS from the WDW equation (IMAGE) Tata Institute of Fundamental Research Caption AdS can be visualized as a cylinder with time running on the vertical axis. In ordinary theories (subfigure (a)) one needs information on the boundary for an extended time-interval to reconstruct physics at the central point P. The new study shows that, in a theory of quantum gravity, the physics in the middle of the space can be reconstructed from an infinitesimal part of the boundary (subfigure(b)). Credit C.
