Reply to comment by TiredOfRatRacing in How likely is it that Betelgeuse will supernova? by tempejkl

That wasn't the question. If it already supernova'd then the chances of it doing it in the next 100 years are 0.

But if it already supernovaed, and we havent seen it, then from our perspective, we dont know that it has or will soon. So the chances of our seeing it are unknown since we are unaware it may have happened already.

stars don't just randomly go supernova. There is a long and predictable lifecycle of stars that lasts way longer than 500ish years.

Well yeah. Betelgeuse is nearing the end of its lifespan. That’s why I asked.
