The worldvolume geometry of the brane is an FRW big-bang/big-crunch spacetime. In favorable circumstances\ , the brane acts as a Randall-Sundrum Planck brane so that gravity localiz es. We describe a microscopic construction for such an end-of-the-world br ane with localized gravity in AdS/CFT\, starting from N=4 SYM theory. We s uggest specific microscopic states of N=4 SYM theory that may encode the p hysics in a four-dimensional cosmological spacetime.\n LOCATION:https://researchseminars.org/talk/Kadanoff/11/ END:VEVENT END:VCALENDAR
