Thank you for the detailed response! I am hoping we can at least get some answers toward a unified theory soon, hopefully in my lifetime lol

Reply to comment by ZackyZack in Eli5 Why can’t Stars use Iron in nuclear fusion? by Drippidy
That I do understand, but I wasn't sure if heavier elements fuse while the star is still active or if there is absolutely no fusion beyond iron until it blows up

Does it happen anyway? I understand that it would take energy rather than give, but do the extreme conditions in the core of such a star cause the fusion to happen anyway and steal some of the stars energy?

I got screwed. I really could have used a 3rd nipple back in 2004

That's pretty interesting, hadnt thought about the unique geometries that allow flatness but still are unbounded. There doesn't appear to be any reason it would be a torus but I suppose there is no reason for it to be any shape, it just is whatever shape it is.
Tying to understand these concepts in a human mind is dizzying sometimes. I hope I can stay the course and continue studying and eventually join the effort to answer these questions
