TFW you walk outside to check if Betelgeuse is still there (I just did, it is).https://twitter.com/cplberry/status/1216917328841117696 …

For the record, I do know that it can take hours for the shock to reach the surface. I didn't point that out initially because I didn't want people staying up all night to watch Betelgeuse. I was mostly joking (but I did walk outside because I couldn't resist).
It isn't Betelgeuse blowing up because: - It is outside the GW localization region. - The burst might not even be real. - The burst was probably too short. - No neutrinos were detected - Betelgeuse's dimming is well explained. Me walking outside to check = buying a lottery ticket
Because honestly Betelgeuse blowing up would be far more exciting than winning the lottery. Lottery winners happen every day. It has been 400 years since humans have seen a supernova in our galaxy, and I'm one of the best prepared people on the planet for it.
Can we get a new Betelgeuse movie already @MichaelKeaton? The universe is providing *so much* free publicity.
@aussiastronomer @LIGO just confirming, the two lobes of the likely gravitational location are orthogonal to the interpreted/assumed Betelgeuse axis of rotation (about 55 degrees from galactic north, etc) and not aligned with it? I'm mobile and don't have my full toolkit along..
Betcha $5 the red circles are where the explosions will head for- it's gone, and light hasn't reached us yet. Me- I'll just wait for the sudden light to switch on outside.
Nice map! Constellation time: Orion is bottom right. Lambda Gemini is 4th mag star in the inner 50% localization (37 square degree oval). The Twins are above left, and Procyon in Canis Minor is the bright one below and to the left. #S200114f #LIGO More: http://treasuremap.space/alerts?graceids=S200114f …
If the core collapsed it would take 30 minutes for a shock moving at c to reach Betelgeuse's surface. And the shock would most likely be moving more like ~10% c. So you wouldn't see anything in optical for a few hours anyway...
NOT that this is what this is. I definitely didn't feel any neutrinos pass through my body, which I totally would have.
Would appropriate modeling shift the contours?
