Now if it's always been common knowledge that gravity alone could get the job done, why was the supernova model even invented?
Why not both? At the beginning when there were only hydrogen and helium (right after the big bang event), certain already dense regions accumulated into interstellar clouds and gravity eventually contract these gas clouds into newly formed stars. The hydrogen burning (or fusion) that occur within these stars create helium, then helium burning creates heavier elements, and so on and so forth. Eventually, some stars run out of fuel and is massive enough that when they collapse under their own weight they become supernovas. During these short violent events, even heavier elements are created while the explosions themselves send these elements back into the interstellar medium. These materials eventually condense again and form another generation of stars. And so on and so forth.
I'm not trying to pick on you, but so far your responses have been little better than "I heard somewhere that Darwin doubted his own theory, therefore evolution is false..."
your model might be good.
I'm sorry, but I have not presented any model to speak of. You are making this harder than it is.
Here's what happened so far. The thread started said that he thought gravity wasn't enough to overcome the gas's tendency to expand. I introduced honest to god math calculations that showed otherwise. You came in and said something like in the great scheme of things I'm wrong. I asked specifically why I was wrong and you answered that you heard somewhere that I was wrong, therefore I was wrong.
It would really help if you could be a little more specific than simply repeating "It is very well known that you're wrong, therefore you're wrong..." I mean, throw me a bone here. Tell me what's wrong?
Last I knew, it was pretty well agreed that it isn't.
May I propose the following explanation? Please note that it is only a hypothesis.
Is it possible that the community you refer to that "pretty well agreed" about this thing is the very same community that wants the young earth creationist model taught in school?
I know from personal experience that it was pretty well agreed that if the earth was a few miles from its current orbit that all life on earth would end immediately, proving that this razor thin region of space that earth occupies must be proof of divine intervention. To me, this "fact" remained pretty well known until I stopped being a fundamentalist christian and someone pointed out to me that earth is several million miles farther away from the sun during summer than during winter. After that, this pretty well known fact stopped being so well known.
What I'm saying is is it possible that, like me, you've been living a sheltered life?
