Charged Black Holes Emit Charged Particles, and Quantum Gravity Corrections Barely Matter
Quantum corrections to near-extremal black holes drastically rewrite the Hawking spectrum for photons and gravitons, but switch to charged particles and the corrections nearly vanish — because the particles are mostly produced in the throat, far from the horizon, where they cannot feel the metric fluctuations near the horizon.

Planet formation works by dust collapsing on its own, not by gas turbulence
Purely hydrodynamic instabilities like VSI and COS stir dust back into the atmosphere and cannot make planetesimals; only letting dust feed back actively, or even letting gas accrete, can compress dust to collapse densities.
