"私たちのDNAの中の窒素、私たちの歯の中のカルシウム、私たちの血液の中の鉄、私たちのアップルパイの中の炭素は、崩壊する星の内部で作られました。私たちは星の物質でできています。"
— Carl Sagan
Simplified Meaning:
Everything in our bodies, like the calcium in our teeth and the iron in our blood, originally came from stars that exploded long ago. These stars created the elements we are made of. Just think about it: the stars in the sky are like huge factories making all the building blocks that eventually form everything on Earth, including us. It's like baking a cake where the ingredients came from really far away, but they all combine to make something whole and unique. This idea helps us understand that every part of us is connected to the universe in a very real way. By seeing ourselves as pieces of the stars, we might feel a greater appreciation for life and a sense of connection to the cosmos.
