화장 후 남는 것은 ‘재’가 아니었다… 우리 뼈 속 칼슘에 숨겨진 별의 비밀 | 과학다큐

What Remains After Cremation Was Not ‘Ashes’… The Star’s Secret Hidden in the Calcium in Our Bones | Science Documentary What exactly remains in our bodies after death? We calmly trace the true nature of the bones and calcium left behind after cremation, and how that calcium was formed in stars billions of years ago. 🌌 This is a science documentary that examines the history of the universe contained within a handful of remains. Discover the story of how the substance we thought was ash is actually the trace of bones, and how the calcium within them has traveled through the long journey of stars. Through the process in which stellar elements formed Earth and life and returned to nature, we present a new perspective on life and death through science documentaries. Within the "stardust" Carl Sagan spoke of and the 13.8 billion years of cosmic time, what kind of existence are humans? Through this science documentary, we reflect on where we came from and where we are returning to. Is death the end of everything, or the beginning of another cycle? Please stay with us until the end for this science documentary that captures the long journey of stars, humans, and atoms. ✨ Look up at the night sky tonight and take a moment to reflect on how special the people by your side and our lives are. We hope you also discover the next stories of the universe along with this science documentary. #ScienceDocumentary #SpaceDocumentary #CarlSagan #MysteriesOfTheUniverse #Stardust #SpaceScience #Astronomy #ScienceStories #HumanAndUniverse #DeathAndLife 00:00 Questions about what remains until the very end after most of the body disappears following cremation 03:18 Carl Sagan's story of 'Stardust,' which posits that the elements in our bodies came from stars 05:29 The process where water and organic tissue turn into gas during cremation, leaving only bones behind 07:49 The true identity of cremated remains is not ash, but bone minerals composed of calcium and phosphorus 10:22 Exploring elements created from supernovae and the death of stars while tracing the origin of calcium 14:07 The massive cycle of atoms in our bodies and elements returning to nature after cremation 16:54 The 13.8 billion-year universe and the short time of humans viewed through the cosmic calendar 20:15 Humans made of star elements, the moment they became beings that the universe gazes upon 25:00 Rare stellar explosions and the special birth process of calcium 37:34 Death and A New Perspective on Life: From Stardust Back to the Universe 44:17 We Are Beings Who Come from the Stars and Return to the Stars, and Why Our Current Lives Are Precious ======================= 🔬✨ Mystery Science presents the amazing worlds of neuroscience, philosophy, the unconscious, physics, and science in an easy yet in-depth way through science documentaries.
