If heat is related to a black hole shrinking, and a black hole shrinking is related to information, then perhaps heat is related to information, and vice-versa.

>"In that case, the universe of the far future will be littered with tiny, indestructible black hole remnants — the remains of any black holes that carry even a touch of charge..."
You mean like an atom? Perhaps atoms (and other particles, in fact, all other particles) are really just black holes! Perhaps curved space is a better way to look at it... perhaps all black holes (and all particles) are really just curved space... in fact, perhaps all waves are curved space too...
Which would mean that everything in the universe, all of its particles, all of its waves, all of its contents, including the universe itself... is basically curved space... in one form or another...

>"In a paper published in March in Physical Review Letters, [Garrett] Goon and Riccardo Penco broadened the lessons of the earlier work by proving a simple, universal formula relating energy and entropy. The newfound formula applies to a system such as a gas as well as a black hole."
If gases (particulate matter spread thinly in a thinner medium, i.e., space) can be related to black holes, then black holes can be related to the particles in the gases, which lends additional credence to the idea that all atoms are black holes, although, this being said, it's not a hard proof...

>"When they combine Einstein’s gravity equations and the equations of electromagnetism, they calculate that a black hole’s charge, Q, can never surpass its mass, M, when both are converted into the same fundamental units. Together, the black hole’s mass and charge determine its size — the radius of the event horizon. Meanwhile, the black hole’s charge also creates a second, “inner” horizon, hidden behind the event horizon."
Super weird idea here... if we thought about a black hole of whatever size holographically, as information, then what would be true if the inner, hidden part of the black hole actually contained a miniature replica, a miniature mirror-image -- of ALL of the information inside this universe, a universe-inside-of-a-universe? That's highly speculative of course, but I think it's an idea worth exploring...

">When a black hole hits this point, a simple option for further decay would be to split into two smaller black holes."
You mean like + and - on a battery terminal?
Let me go for "full crackpot theorist" <g>...
What if charge, as we know it, in electricity, is implemented by various clusters of small black holes, regions of curved space, that we have (up until this point in time) been calling by such names as "charge", "electron", "electricity", "potential", "potential difference", etc.
When, what you've got might be multiple black holes, split into pairs, where one is a complex conjugate, a mirror image of the other, and they basically want to unify and annihilate, producing various wavelengths (heat/information) in the process?
All physics should be solvable once the correct identities are established between apparently dissimilar phenomena...
