If I recall correctly, I was told as a student that large stars eventually burn up all thier hydrogen fuel, forge a few of the hevier elements, and then burst into a super-nova, generating a cloud of other hevier elements.
Supposedly, this cloud becomes a nebula, and new stars and planetary systems form from it.
So here's my problem: where is all the hydrogen coming from the create these new stars? Supposedly the old star ran out of the stuff.
This implies that either the new stars are drastically, collosally smaller, or that there is some fission process going on, of which I was not previously aware.
So what's going on here?
