I have a series of questions here all around me attempting to get a better image of what has happened around here over the last 14 billion years. You don’t have to answer them individually. One good explanation might answer them all.
Q1: About how many novas, supernovas and such have the matter in our bodies or in Earth gone through? I assume there’s an estimate based on the proportion of elements or something like that.
Q2: How big were the stars from which we are made? I assume we use to be in some pretty big stars since we have iron. Maybe the first one was really big.
Q3: Did our iron come from one nova and our oxygen come from another? Maybe our stellar nursery was made from several novae.
Q4: Can we tell if any stars near us were made from the same stellar nursery as ours?
Q5: When did the novas occur? If our solar system formed 5 billion years ago, maybe the nova was 6 billion years ago. Maybe there was a flurry of supernovas when the universe was young.
