High School Can Fuzzball Theory Replace Black Hole Singularity?

[wolram]

I know that string theory is not the flavor of the month, but the fuzzball idea circumvents the singularity
which i think is a possible step forwards, is there any other theory that replaces the black hole singularity?

Loop quantum gravity is another attempt to remove the singularity.

I don't think many consider that the singularity present in the vanilla version of GR represents a real physical object,
but on the other hand there have so far been no modified formulations which make testable predictions.
Being mathematically plausible isn't enough.
