I find articles like this both incredibly interesting but perhaps even more confusing.
It must be because the complex math underlying these findings can not accurately be expressed in human language.

#12Maybe a Black Hole destroys information, or perhaps it changes information to a form that we can't (yet) recognize. Presently, both of those states would look the same to us.
I was wondering this about empty space / dark matter. Maybe it's just we're blind to it so far, because assembled in a context of things sensitive to a specific blend of forces.

The further down the theoretical rabbit hole you go, the more so even high-level discussions probably need a general comfort with the field.
Discussion about these soft particles, zero-energy photons and gravitons, being added to a vacuum changing its state out to infinity is pretty fascinating. I would have liked him to explain a little more in-depth how one of these particles could have no energy but still have a spin, though I imagine that's left to the reader to go find the papers that define it.

#14This paragraph really nailed it for me:
"We show that when a charged particle goes in, it adds a soft photon to the black hole. So it adds hair to the black hole. And more generally if any particle goes in—because all particles carry mass and are coupled to gravity—they always add a soft graviton. So there’s a kind of recording device. These soft photons and gravitons record information about what went into the black hole—infinitely more information than we previously believed is recorded by this mechanism. Now whether all information is recorded by this mechanism… I'm pretty sure the answer to that is no, but there are generalizations of this mechanism and then it’s a lot more confusing."
They're showing in this model that perhaps, the event horizon of a black hold acts like this kind of abacus, pushing the photons suspended at the edge of the horizon a little bit in, a little bit out, recording what has fallen over that horizon during the life of the black hole.
That's really, really cool.
