Video: Carl Sagan on the Chemical Elements

1 rating
Carl Sagan discusses atoms; he explains how they are fused together in the interiors of stars. "Where do the natural occuring chemical elements come from? Perhaps a seperate creation for each element? But all the elements are made of the same elementary particles; the Universe all of it, everywhere, is 99.9 percent hydrogen and helium." This video comes from Carl Sagan's Cosmos episode 9, "The Lives of Stars." If you have never seen Cosmos, I strongly recommend it. It's full of great stories like this one. It is available on DVD, in 7 subtitle languages. Purchase links are below.
