Black supernovae and black holes in non-local gravity

Understand

In a previous paper, we studied the interior solution of a collapsing body in a non-local theory of gravity super-renormalizable at the quantum level.

• We found that the classical singularity is replaced by a bounce, after which the body starts expanding.
• A black hole, strictly speaking, never forms.
• The gravitational collapse does not create an event horizon but only an apparent one for a finite time.
