Holographic Space-time (HST) is a proposal for a general theory of Lorentzian space times in which the metric is not a fluctuating quantum variable. Instead, the causal and conformal structures of space-time are encoded in the form of the Hamiltonians, each of which describes evolution in the space-time along a particular time-like trajectory. The quantum descriptions along different trajectories are required to be consistent (a constraint that has not been fully implemented in any existing model). The space-time is a hydrodynamic description of these multiple quantum systems. If time permits, I will sketch the HST models of Minkowski space, eternal stable de Sitter space, a model of inflation and the HST treatment of Anti-deSitter space, as well as the HST resolution of the Firewall Paradox.
