And that moment changed my relationship with Earth. Because for me, Earth had always been a kind of safe haven where I could go to work or be in my home or take my kids to school. But I realized it really wasn’t that. It really is its own spaceship. And I had always been a space traveller. All of us Earth, among all the chaos of the universe, whipping around the sun and the Milky Way galaxy.
