It says “ Our own star and Solar System formed a little more than 4.5 billion years ago, when a molecular cloud collapsed into what became our Sun. As the Sun formed, it did so with a large disk of leftover material about it, spinning. Over time, the material in this disk coalesced into the planets, large gas giants like Jupiter and smaller rocky worlds like our own Earth.” How would one reconcile the fact that the heavy elements in the rocks that formed the earth could only be produced as result of fusion and supernova process? Was the material captured by the hydrogen cloud that later formed the solar system?
