As you might have seen it, @LIGO has detected some weird gravitational waves. I took more than a day to take the time to read everything about it. So, is this new candidate related to #Betelgeuse?
Let's go for a little thread!

Contrarily to what some people said, Betelgeuse is NOT in the 90% zone for the GW. As you can see, it is next to it, probably in the 95% zone. So we cannot exclude that it comes from Betelgeuse, but it is unlikely.
Also, no unusual gamma-rays...
No unusual r-band light...
No unusual visual light...
And no unusual X-rays...
But most importantly, no unusual neutrinos were detected. 2 events were recorded, however 1.4 are expected on average, so that's a p-value of 40% (it's HUGE).
But so... what is it? It seems that it is a supernova burst, however, we don't detect anything else that could suggest it. Is it in another galaxy? Probably not. Further than 40 kpc, a supernova burst would be indistinguishable from background noise. So, if it is a supernova ->
It should be in our galaxy. Is it a sign of an incoming #supernova? A star so close to us that it would produce #gravitational #waves even weeks before exploding? A star like Betelgeuse? I don't believe it's that. I don't even know if this is possible. But I can only hope for it!
