Honestly, that's a lot less rare than I thought. I remember reading a book about black holes saying we had never witnessed a merge, but now that I think about it, I think I read that book a decade ago.
I'm glad we have some real numbers about it. Amazingly cool that we were able to pull this off nonetheless. One of the interesting things I read was that indirect proof of gravity waves was found by observing dual rotating neutron stars. That won a nobel. Maybe this will too.
Cool, cool stuff.
