I was under the impression that our sun is not large enough to form the heavier elements on earth and this means supernova or collision of neutron stars had to be responsible for creating these elements, some of the stuff flying off this explosion formed our solar system, so we could see those progenitor stars.
I thought elements were created inside stars and dispersed by supernovas... Our sun has clearly not exploded yet (and I don't think it's big enough to ever ho supernova), so why does it matter what elements it can create?
