2 particles created around event horizon: out or inside?

[QUOTE="nomadreid, post: 5460701, member: 112452"] Yes, they are definitely entangled. This is what gave rise to this whole flurry around the firewall paradox. (Although I don't completely understand this. I haven't figured out why, without the firewall, the particle inside would necessarily be entangled not only with the outgoing particle but also all the particles which had been "emitted" from the black hole earlier (which then leads to a contradiction). If anyone can explain that point to me, I would be grateful. The explanation given by those favoring [1] is connected with the energy of the infalling particle: that with respect to an outside observer, the outgoing particle would have positive energy, so that the infalling particle would necessarily have negative energy (or, if you object to the phrase "negative energy" here, say that if the outgoing particle adds energy to the equation situation, the infalling one must subtract it), and it is this subtraction of energy that would be greater than the energy added to the black hole by the infalling (anti)particle. Thus, a sum evaporation. [/QUOTE]
