Holographic Space-Time Does Not Predict Firewalls

We use the formalism of Holographic Space-time (HST) to investigate the claim of [1] that old black holes contain a firewall, i.e. an in-falling observer encounters highly excited states at a time much shorter than the light crossing time of the Schwarzschild radius. This conclusion is much less dramatic in HST than in the hypothetical models of quantum gravity used in [1]. In HST there is no dramatic change in particle physics inside the horizon until a time of order the Schwarzschild radius.
