I was wondering about that too. I guess some figure the collapse would
not be symmetrical, but 14 milliseconds seems really really short to
me. I wouldn't be surprised if the cause was something completely
unknown; 2 sub solar mass Black Holes coalescing maybe? That would be
really exciting if true. Black Holes that small would pretty much have
to be primordial, I can't think of anything except the Big Bang itself
that would have conditions extreme enough to produce them.

Well, if it's any help, a black with a mass of 55 metric tons has
lifetime of 14 ms. It's also much smaller than a proton.
