Somewhere, something incredible is waiting to be known.

“What makes the universe so hard to comprehend is that there's nothing to compare it with.”

“Our sun is one of 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living things in that enormous immensity.”

“The size of the universe depresses many people, but not me, I'm delighted at it.”
