Ostwald's Ripening is a phenomenon where the surface area to volume ratio of droplets causes small particles to shrink until they disappear and for droplets above a certain volume to continuously grow. This is due to mechanisms of evaporation and condensation, which I don't fully understand in this specific case. My first thought upon hearing this is "this sounds like black holes".
Hawking Radiation is a mechanism through which a black hole emits matter-energy from its event horizon. The power of this radiation is related to surface area, and in a naive sense, surface area is proportional to mass. This is as opposed to a 2/3rds power in the case of an incompressible drop held together by surface tension, but it's still monotonic and increasing which is what matters for the law to apply. Thus, all black holes are radiating, but small ones are doing so at a much greater rate relative to their mass. There is also a certain cutoff beyond which the temperature of the black hole is lower than the Cosmic Microwave Background (CMB) so the radiative balance can only permit it to grow bigger.
I'm surprised to not find any real mention of Ostwald's Ripening and black holes in the same paper. Has this terminology ever been entertained by physicists? I think Ostwald's Ripening is a physical law, although I might be trying to apply it in a cross-disciplinary sense.
Perhaps it's also valid to ask if this applies for cosmology in a larger sense. If the current thinking is to accept an apparent inevitability of a big rip, would the swelling and consolidation of black holes continue indefinitely, or would a lowering of the CMB due to the universal acceleration cause all black holes to evaporate way in the future? Is this question trivial or non-trivial?
