New Maps of the Bizarre, Chaotic Space-Time Inside Black Holes

https://www.quantamagazine.org/new-maps-of-the-bizarre-chaotic-space-time-inside-black-holes-20250224/

Physicists have been revisiting the chaos around singularities with computational power and algorithms that make possible numerical simulations consistent with decoupling, refering to regions of space-time that become disconnected in the presence of strong gravitational fields such as black holes. They hope to prove that the approximations Charles Misner and others made of Einsteinian gravity are valid. Simulations of singularities may help reconcile general relativity with quantum mechanics in a theory of quantum gravity.
