> 2/3 LIGO detections imply one of the merging pair of black holes should be a naked singularity.

Where did you get this impression? All of the LIGO results are consistent with "standard" GR black holes whose event horizons merge.

Thanks for the links. I find it unfortunate that often in science (and especially with the LIGO data) much is written about what could possibly be lurking in the data but isn't actually favored over our current understanding.

This creates more interest, but can obfuscate what the real situation in the field is. In this case, while Gravastars are certainly something many scientists actively do and should consider, there is no real evidence from the LIGO data that favors the hypothesis of "we are in a universe that lacks causality" over the observation of the merger of two Kerr black holes.

I think you're being a bit harsh. Is there any empirical evidence that favors classic black holes over gravastars, or is our "current understanding" just a matter of what we thought of first? If the latter, take a chill pill and let us enjoy the possibilities. :)

Yes.

So you're still left with gravastar models that can co-exist with black holes.
