당신 몸 속과 모든 물 분자에 포함되어 있는 수소는 빅뱅에서 유래했다. 우주에서 수소를 만들어 낼 다른 가능한 기원은 없다. 당신 몸 속의 탄소와 산소는 별 내부에서 핵 융합을 통해 만들어졌다. 몸 속의 철 대부분은 아주 오래 전 멀리 초신성이 폭발하면서 만들었다. 당신 보석에 들어있는 은 중성자별이 충돌하면서 아주 짧은 주기의 감마선 폭발 천체가 되는 순간 만들어졌다. 우리 몸 속에 존재하는 황과 구리와 같은 원소들은 아주 적은 양이지만 생명을 이루는 주요 성분이다. 위의 주기율표는 인류의 가장 큰 궁금증인 모든 원소들의 핵의 기원을 색으로 표현한 것이다. 구리와 같은 원소들의 핵의 형성은 아직 잘 밝혀지지 않았으며 여전히 관측과 컴퓨터 계산 연구 분야에서 뜨거운 주제다.

Explanation: The hydrogen in your body, 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. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your 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 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 creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.
