The Most Astounding Fact

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.
