*“Dynamical Formation of Regular Black Holes"*
*
*

_Abstract_
I will show that regular black holes arise as the unique spherically 
symmetric solutions of broad families of generalizations of Einstein 
gravity involving infinite towers of higher-curvature corrections in D≥5 
spacetime dimensions. Our results are facilitated by the use of a class 
of theories that possess second-order equations on spherically symmetric 
metrics, but which are general enough to provide a basis for the 
gravitational effective action. I will argue that such regular black 
holes arise as the byproduct of gravitational collapse within these 
theories. Generically, spherical stars or shells collapse until they 
reach a minimum size inside the inner horizon of the black hole they 
create. Then, they bounce back and reappear through a white hole in a 
different universe, where they eventually reach their original size, 
restarting the process. I will also mention several ongoing research 
directions.
