"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.
