Very clear i hadn't realised the photons would lag the neutrinos. A typo 1604 for 1064?

No, 1604 was Kepler's supernova: the last one seen in our Milky Way with the naked eye. There was also a 1054 supernova, and that's where the Crab Nebula comes from.

Question: At 900 solar masses, is Betelgeuse large enough to form a black hole post super nova or will it just eventually become a red dwarf, taking another few billion years to burn out?
-
Betelgeuse is only 20 solar masses: supernova + neutron star is the most likely fate.

I heard mention of a gravitational wave detection coming from the direction of Orion recently, was that just a coincidence? Regardless, would LIGO be able to detect a nearby Super Nova?
-
Almost certainly coincidence. If it was due to a supernova, we'd have seen the neutrinos by now.

,,The energy spectrum of the neutrinos produced in the core, the one observable we know will change, is irrelevant, as the neutrino flux is far too low to be detectable from hundreds of light-years away.'' - this is far from true, see e.g:https://www.sciencedirect.com/science/article/pii/S0927650504000349 …

If those rates and cross-sections are correct, should we be seeing neutrinos produced in other fusion phases? Carbon, neon, oxygen, even magnesium maybe? If we can look at this and say, "it isn't silicon burning" is there anything else we can say it is or isn't doing?

I would really like to read this, but http://forbes.com is filled with tons of ads and pop up videos that repeatedly crash my brand new iPad. I’ll tolerate ads, but
@Forbes had gone too far and it’s made your articles unreadable. -
You'll just have to follow my articles on Patreon or on Medium if you don't want to get them from Forbes.
