Maybe primordial black holes coalesced.

This hasn't been observed. Primordial black holes are very hypothetical
and micro lensing observations rule them out as you said when discussing
with Mr Oldershaw...

Strange, now you think that they exist. Do you have any observations
that point to those primordial black holes?
