The hydrogen in our bodies, present in every molecule of water, came from the Big Bang There are no other appreciable sources of hydrogen in the universe. The carbon in our bodies was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in our bodies was made during supernovas of stars that occurred long ago and far away. The gold in our jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-=ray bursts. Elements like phosphorus and copper are present in our bodies only in small amounts but are essential to the functioning of all known life. This periodic table is color coded to indicate humanity’s best guess as to the nuclear origin all known elements. The sites of nuclear creations of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.
The only thing we can truly bequeath to the next generation are Roots and Wings. I hope this blog inspires you to share yours.
