Six black hole merges observed in ~2 years! That's quite interesting. More observations will make for some useful statistical study.
I wonder if this would give us any insights w.r.t. matter and its distribution across the Universe, and/or help us better understand/estimate dark matter/energy.

The odds are still very low on MACHO's as a source of most dark matter.
- nerfhammer 9y agoMost interesting is that these have all been medium-sized black holes which weren't known to exist previously and we don't have a theory of how they form.
