Systems of enhanced memory capacity are subjected to a universal effect of memory burden, which suppresses their decay. In this paper, we study a prototype model to show that memory burden can be overcome by rewriting stored quantum information from one set of degrees of freedom to another one. However, due to a suppressed rate of rewriting, the evolution becomes extremely slow compared to the initial stage. Applied to black holes, this predicts a metamorphosis, including a drastic deviation from Hawking evaporation, at the latest after losing half of the mass. This raises a tantalizing question about the fate of a black hole. As two likely options, it can either become extremely long lived or decay via a new classical instability into gravitational lumps. The first option would open up a new window for small primordial black holes as viable dark matter candidates.

Probabilistic Causality from Graviton Fluctuations
In a thermal state of gravitons at temperature T, metric fluctuations induce a Gaussian spread in the causal structure of a scalar field with Var(x²) = 16 G_N T t³ / 3 after vacuum subtraction.

Evaporating cosmologically coupled black holes
If a black hole's mass grows with cosmic expansion, Hawking evaporation is slowed or reversed, weakening gamma-ray bounds on primordial black holes.

Black Hole Memory Burden and its Signatures in Gravitational Waves from Mergers
Swift memory burden shifts black-hole quasinormal-mode frequencies by an amount set by the memory-load parameter μ and critical exponent p, with μ able to exceed the progenitor's information content.

In-depth analysis of the clustering of dark matter particles around primordial black holes. Part II. Analytical prescriptions for spikes
A 'soft' analytical approximation reproduces PBH minispike densities and annihilation rates to ~±15%, and shows that a discovered sub-solar PBH population would strongly constrain s-wave WIMP dark matter.

Hawking Radiation in $f(\mathcal{R})$ Gravity: Survival of lighter black holes
Non-rotating black holes in the studied f(R) model can survive to the present day down to masses ~5×10^13 g (for large |B|), roughly ten times lighter than the GR threshold.

Light scalars in light of UV/IR mixing: classicalization via synergy between Vainshtein and chameleon screenings
Classicalizing k-essence scalars need m << Λ* and, when potentials or fermion couplings are present, a chameleon-like screening layer to keep Vainshtein screening and classicalon stability intact.
