Neil DeGrasse Tyson answers the question, ‘What is the most astounding fact you can share with us about the Universe?’
Sounds very similar to what Carl Sagan said (in Cosmos: A Personal Voyage):
Some part of our being knows this is where we came from. We long to return. And we can. Because the cosmos is also within us. We’re made of star-stuff. We are a way for the cosmos to know itself. (Emphasis mine.)
What an amazing and beautiful fact about ourselves and our universe.
