I’m not deriding you. But you have confused the forming of a white dwarf with the process which a much larger star goes through to form a black hole. Our star will likely eventually become a white dwarf, but is not massive enough to collapse into/become a black hole. And the phrasing regarding ‘taking in helium’ is, well, cryptic at best.
It’s cryptic, yes, but it’s cryptic based on a 35 year old recollection.
Also, while nuclear fusion is complex, the fuel and by-product aren’t. Hydrogen in, helium out. That’s all most of us need to know, really.
Sorry, but the previous poster got a bit smarmy about it and you got caught in the crossfire.
Do you her name, BTW?
