…What do you think is going on with black holes? As information-storing and processing units, what do you think is going on with black holes? Black holes are really fascinating objects. They’re at the interphase between quantum mechanics and gravity, and so they help us test all sorts of ideas. I think that for many decades now, there’s been this black hole information paradox that things that fall into the black hole, we’ve seem to have lost their information. Now, I think there’s this firewall paradox that has been allegedly resolved in recent years by a former peer of mine, who’s now a professor at Berkeley. There, it seems like, as information falls into a black hole, there’s a sedimentation. As you get closer and closer to the horizon from the point of view, the observer on the outside, the object slows down infinitely as it gets closer and closer. Everything that is falling to a black hole, from our perspective, gets sedimented and tacked on to the near horizon. At some point, it gets so close to the horizon, it’s in the proximity or the scale in which quantum effects and quantum fluctuations matter. There, that infalling matter could interfere with the traditional pictures, that it could interfere with the creation and annihilation of particles and antiparticles in the vacuum. Through this interference, one of the particles gets entangled with the infalling information and one of them is now free and escapes. That’s how there’s mutual information between the outgoing radiation and the infalling matter. But getting that calculation right, I think we’re only just starting to put the pieces together. There’s a few pothead-like questions I want to ask you.…
