"The Cosmos is within us. We are made of star stuff. We are a way for the Cosmos to know itself." - Carl Sagan
The atoms in our bodies were created in exploding stars |
Who can forget the measured, poetic presentation of Carl Sagan when in Cosmos (1980) he first explained to a wrapped world of television viewers the fantastic fact that we are star stuff? (Scroll down to watch the video.)
Previously existing stars had blown apart to produce some of
the elements from which our human bodies are composed. More of our elemental
atoms were the product of a second generation of stars accumulating that same
star stuff and in their explosive deaths compressed those lighter elements
further along the atomic table to produce all of the remaining heavier atoms
essential for our existence.
