To Infinity and Beyond Quotes

“If we could solve all the problems that the society of a generational spaceship might face, then we needn’t set out for a Planet B in the first place. As far as we can tell at present, Earth is an isolated world, alone in the universe, caught in orbit around our star for billions of years with no food, medicine, or air to replenish what we use or destroy. If we fail on this world, where we surely know our failure could mean extermination, can we reasonably expect different results out there, lost to the sea of space?”
― Neil deGrasse Tyson, To Infinity and Beyond: A Journey of Cosmic Discovery

“We all move forward into our own future at exactly one second per second—but we cannot visit with the dead or meet our unborn great-great-grandchildren. Every passing second is at once a slammed and an opened door as time carries us away from what has been to what is and what will be until the day we arrive at our final spacetime destination. Our regrets and worries may subside as our bodies weaken and age, but our pasts and futures remain as inaccessible to us as the farthest star in the sky—at least for now.”
