However if I had no spaceship and was just freely falling through the Event Horizon the Hawking Radiation wouldn't bother me at all; or at least that was the idea before 5 or 6 years ago when the firewall/ entanglement business came up which seems to say even the freely falling man will be cooked at the Event Horizon, he would reach the Planck temperature which is about 10^32 K, but I don't understand Black Hole Firewalls worth a damn. http://www.nature.com/news/astrophysics-fire-in-the-hole-1.12726#b8 Most Hawking radiation originates where the tidal forces are the greatest, and that would be at the Event Horizon. The closer I hover above the Event Horizon the slower my clock will tick, so if I hover close enough I can watch the entire Black Hole evaporate away in just a few minutes by my clock even though for you back on Earth that would take a billion trillion years or so. The thing that causes Black Hole evaporation is Hawking radiation, so if I observe one I'm going to have to observe the other, although "observe" may not be the right word, "incinerate" might be better. I understand why after half the Black Hole has evaporated further radiated photons would, on the face of it, be entangled with 3 things, and if that is forbidden by quantum mechanics then one of those entanglements would need to be broken . But what I don't understand is why breaking the quantum link with the Black Hole would make things hot. Joseph Polchinski, they guy who came up with the firewall idea said: *“It’s a violent process, like breaking the bonds of a molecule, and it releases energy.The energy generated by severing lots of twins would be enormous. The event horizon would literally be a ring of fire that burns anyone falling through”* But why? Why would breaking quantum entanglement release energy and produce heat, what does one have to do with the other? I hope somebody on the list who understands Black Hole Firewalls better than I do can explain this to me.
