Betelgeuse might go off

RE: Betelgeuse might go off
I will be sure to run around, waving my arms, screaming “repent! the end is nigh!” when the neutrinos arrive so I can say “I told you so” when light appears in the sky.

good plan!

Dangerous things neutrinos.

Which of the following would be brighter, in terms of the amount of energy delivered to your retina:

  1. A supernova, seen from as far away as the Sun is from the Earth, or
  2. The detonation of a hydrogen bomb pressed against your eyeball?

The supernova is brighter, by nine orders of magnitude.

It's amazing 'science' always seems to 'find' whatever it is funded for, and never the oppsite. Drich.

The difference between the two distances, on a cosmic scale, are essentially zero so that's not really hard to sort out.

Take the distance from Betelgeuse to here in miles. Subtract the distance from the Sun to here. You won't even notice the loss until you get out to fourteen digits or so.

teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"

Think of it this way,  if you created an entire Dyson sphere around the sun built solely from quintillions and quintillions of Czar Bomba - the most powerful hydrogen bomb ever detonated by man - laid side by side like bricks in a wall,  and detonated all those czar bombas simultaneously,  the colossal explosion would be but less than one ten thousandth as powerful as a supernova.

Incidentally, it would take ball park of thousand quintillions of Czar bombas to make up a Dyson sphere around the sun.

But that may sound less amazing if you realize even an inconceivably large structure such as a Dyson sphere would actually be smaller than any candidate star about to go supernova.
