Physics says identical particles are impossible to tell apart, but that rule might totally break down once you get close to a black hole.

When identical particles cease to be indistinguishable: violation of statistics in quantum spacetime
arXiv · 2603.25552
The Takeaway
Physics currently assumes that every electron in the universe is exactly identical and interchangeable, a principle that prevents atoms from collapsing. This paper suggests that the tiny fluctuations of quantum spacetime could actually make particles distinguishable, which would allow for 'forbidden' atomic behaviors that scientists can now search for in experiments.
From the abstract
Quantum gravity may modify the fundamental symmetries that govern identical particles. In particular, noncommutative spacetime frameworks predict deformations of Bose and Fermi statistics. Here we develop a relativistic quantum field theory based on the most general oscillator algebra compatible with $\theta$-deformed Poincaré symmetry. This construction generalizes twisted statistics to a class of quon-like deformations allowing non-involutive particle exchange. We show that the resulting theor
