Regarding the quote in Chapter 1:

“We are all connected to each other biologically, to the Earth chemically, and to the rest of the universe atomically”

While I originally attributed this quote to Carl Sagan, Neil deGrasse Tyson has also spoken eloquently about the interconnectedness of our universe. Although Carl Sagan’s book Cosmos (1980) expresses similar ideas, I couldn’t verify this exact phrasing being used by him. As Sagan so poignantly wrote, “The cosmos is within us. We are made of star-stuff. We are a way for the cosmos to know itself” (Cosmos, 1980). Both Sagan and Tyson have profoundly influenced our understanding of our connection to the universe, and we acknowledge their contributions to this important idea.
