I recently downloaded LIGO's gravitational wave app for my iPhone. I see that there are something like 31 events marked "GW19...." suggesting that they've 'reported' 31 events this year which weren't injected signals and later retracted. The last one occurred a few days ago on the 15th of this month. They are assigned a range of "confidence" from a low of 49 percent to a high of 100 percent, with most of them listed in the 90+ percent category.
Even with three detectors however and the ability to isolate the signal to a much smaller region of the sky, and even with an improved ability to let astronomers know about the events in real time as they happen, I still don't see any evidence to suggest that any of them have been confirmed by any external piece of equipment, not by any telescopes and not from neutrino detectors. As far as I can tell, there hasn't been a single multi-messenger event in 2019, even though some of them are listed as binary neutron star events and black hole/neutron star merger events.
Am I the only one that finds the lack of confirmation of any of these events to be highly suspicious? How could every single one of these merger events take place without emitting enough light or emitting enough excess neutrinos to be detected by other types of equipment?
I must say, I'm actually starting to wonder if the single multimessenger event in 2017 was simply a statistical fluke, a random coincidence of lucky timing. It's just hard to believe that all these 2019 events release *massive* amounts of energy in the form of gravitational waves, and yet none of them emit anything substantial in the EM spectrum, or in increased neutrino emissions. It seems kinda fishy to me that they'd all be "naked" black hole merger events, and in fact some of them are listed as "BNS" merger events which should be visible events like the 2017 event.
It looks to me like LIGO/Virgo are 0 for 31 in terms of externally supporting any of their GW claims from this year. That's a pretty terrible batting average.
