Definitely not my field, but a colleague of mine in grad school who was doing GR stuff was convinced that black holes didn't have singularities.

As I recall (it was a long time ago), it was mostly an aesthetic preference, he felt it was far more likely that at very high curvatures or energies or both, the domain of validity of GR would be exceeded, and Something Else would happen that preserved the theory in the low-curvature regime.

It sounds like that's not even required, if I'm reading this right (did I mention it's not my field?), it sounds like even within GR, singularities are avoidable? Very cool.

Many physicists believe that no singularity can phisically exist in nature and that they are just our lack of a better theory.

Isn't an electron a singularity in this kind of sense? A mathematical point with some fields, and a certain mass.
