“I believe that the only way that the human race is gonna survive is to start colonizing space and setting up colonies on the moon, and then space stations.”

“I don't think the human race will survive the next thousand years, unless we spread into space.”

“Because the space race is overAnd I can't help but feel that we've all grown up too soon.- The Space Race Is Over”

“This space station [Yang Liwei] was little more than a giant Orbital Denial Station. If those charges were to detonate, the debris...any future space launch would be grounded for years. It was a "Scorched Space" policy. "If we can't have it, neither can anyone else.”

“I went on happily reading well into the night, when no one ventured on to the decks of the Donizetti, except for sinful shadows who were careful not to interrupt me, careful not to disturb my reading, happiness, happiness, passion regained, genuine devotion, my prayers rising up and up through the clouds to the realm of pure music, to what for want of a better name we call the choir of the angels, a non-human space but undoubtedly the only imaginable space we humans can truly inhabit, an uninhabitable space but the only one worth inhabiting, a space in which we shall cease to be but the only space in which we can be what we truly are...”

“Few religions are definite about the size of Heaven, but on the planet Earth the Book of Revelation (ch. XXI, v.16) gives it as a cube 12,000 furlongs on a side. This is somewhat less than 500,000,000,000,000,000,000 cubic feet. Even allowing that the Heavenly Host and other essential services take up at least two thirds of this space, this leaves about one million cubic feet of space for each human occupant- assuming that every creature that could be called ‘human’ is allowed in, and the the human race eventually totals a thousand times the numbers of humans alive up until now. This is such a generous amount of space that it suggests that room has also been provided for some alien races or - a happy thought - that pets are allowed.”
