EP351 卡爾薩根｜我們都是星塵：人類史上最美麗的科學句子

卡爾薩根說了一句話：我們都是星塵。 他說這不是詩。這是事實。你血液裡的鐵，曾經在一顆垂死的星球核心閃耀過。那顆星爆炸了，把鐵拋撒到宇宙空間，幾十億年後那些鐵成了你的一部分。 薩根是天文學家。他是康乃爾大學的教授，是美國航太總署的顧問，是普立茲獎得主。但最讓五億人記得他的，是他推出的電視系列「宇宙」——他用一個節目，讓幾乎不讀科學書的人，開始對宇宙產生了好奇。 他提議讓旅行者號在離開太陽系前回頭拍了一張照片。地球在那張照片裡只有〇點一個像素。他看著那個小點，寫下了「暗淡藍點」——這篇文字後來被稱為科學史上最美的文字之一。 他說：非凡的主張需要非凡的證據。他窮盡一生對抗迷信和假資訊。在今天的世界，這句話比任何時候都更需要被聽見。 這集我們說卡爾薩根。說那個讓宇宙有了溫度的人。 Carl Sagan said something that many people call the most beautiful sentence in the history of science: we are all made of star stuff. He was not being poetic. He was stating a fact. The iron in your blood was forged in the core of a dying star billions of years ago. That star exploded, scattering those elements through space. Over billions of years, they gathered, formed planets, formed oceans, formed life, and eventually became you. Sagan was an astronomer, Cornell professor, NASA advisor, and Pulitzer Prize winner. But what five hundred million people remember is the television series Cosmos, which he created in 1980. It aired in sixty countries and is still one of the most widely watched public television programs ever made. He made people who never read a science book genuinely curious about the universe. He also proposed that the Voyager 1 spacecraft turn around before leaving the solar system and photograph Earth from six billion kilometers away. Earth appeared as a barely visible dot, 0.12 pixels, suspended in a sunbeam. He wrote a reflection on that image called the Pale Blue Dot, which remains one of the most moving pieces of scientific writing ever produced. He spent his life fighting pseudoscience and misinformation, and wrote The Demon-Haunted World to give ordinary people the tools of critical thinking. In today's world, his message has never been more needed. In this episode we tell the full story of Carl Sagan. The man who gave the cosmos a human heartbeat. 卡爾薩根, Carl Sagan, 宇宙, 星塵, 暗淡藍點, 天文學, 科學普及, 旅行者號, 向大師致敬, 沉思者J, Thinker J, Cosmos, Pale Blue Dot, astronomy, science communication, critical thinking, NASA, stardust, universe, wonder Powered by Firstory Hosting
