A PBS Space Time episode on fuzzballs, the string-theory proposal for black holes that replaces the singularity with a tangle of strings. It explains why black holes seem to both have to exist and break known physics.
Cited as an accessible pointer when threads discuss black hole models that avoid singularities.

this video There are a number of theories on black holes not being singularities. PBS space time goes into a few of them
Black holes would be different if string theory is right. There would be no singularity, for instance, and no interior. String theory black holes (which are called fuzzballs) would emit slightly different gravitational waves when they merge. We should have sensitive enough gravitation wave detecters in the not too distant future to check this. There was a PBS Space Time episode on fuzzballs last November [1]. [1] this video
