## The "Spacetime Map" as a Model of Juan Maldacena's 5-Dimensional Holographic Universe

**Authors:** John A. Gowan

In 1997 the Argentinean physicist Juan Maldacena produced a mathematically rigorous
model of a hypothetical 5-dimensional Universe which conforms to certain principles of
the holographic metaphor. In Maldacena's model a 4-D Universe (3 space, 1 time) is the
boundary membrane of the 5-D "bulk" Universe (4 space, 1 time). The physics in the two
Universes are virtually indistinguishable, except that the 4-D Universe lacks gravity while
the 5-D Universe is gravitational. Maldacena's model seems to fit my own "Spacetime
Map of the Universe", which I have consequently come to interpret as a map of a 5-dimensional
Cosmos, incorporating 4 large spatial dimensions and 1 time dimension.
