Neil deGrasse Tyson often speaks about the idea that we are literally stardust. This concept, popularized by Carl Sagan, refers to the fact that the elements that make up our bodies were forged in the hearts of stars that later exploded as supernovae, scattering their material across the galaxy. Tyson emphasizes that this connection is not metaphorical, but a literal fact of our physical composition.
