Unfortunately, some fairly serious health issues have prevented me from keeping this thread updated. I'm hoping things are looking up now and will try to update everyone on research results I've missed over the last couple of months or so. In the meantime, there's this recent one:
Primordial black holes may not be as abundant as thought.
The late Stephen Hawking had an hypothesis that the early universe was full of tiny black holes and that they make a significant contribution to the dark matter in the universe. Years ago I remember reading a paper that suggested that the Tunguska event (https://en.wikipedia.org/wiki/Tunguska_event) was caused by a mini black hole.
Latest observations from the Subaru Telescope on MK suggest that these tiny and primordial black holes are extremely rare and are an insignificant contributor to dark matter.
