Where Your Elements Came From Explanation: The hydrogen in your body and 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 your body was made by nuclear fusion in the interior of stars, as was the oxygen .

The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events . Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life . The featured periodic table is color coded to indicate humanity ‘s best guess as to the nuclear origin of all known elements. The sites of nuclear creat
