The universe encompasses everything that has ever existed or will exist — there is nothing beyond it. Even our most basic attempts to comprehend its scale produce a visceral, almost physical reaction: a nervous excitement, a sense of awe, as if standing at the edge of something so vast and unknowable that the mind recoils even as it reaches forward.
Sagan spent his career at Cornell translating cosmic science for ordinary people through Cosmos: A Personal Voyage and Pale Blue Dot.
