“Life can exist on other planets, in other solar systems, in other galaxies and universes.”

“I don't see how you can be saying this. Look. You want to take…you want your god to take responsibility for the huge number of collapsing stars and imploding galaxies and destroyed universes and failed solar systems that have left us in this tiny corner on the one planet in this petty solar system that can support life some of the time on some of its surface. And you want a creator who filled this earth with species, since life began 99% of which are now extinct already…and this is some design, isn't it?”

“Our own galaxy system is only one of a great many, and observations made from any of the others would show exactly the same thing: all systems are receding, not from any particular centre, but from each other: the whole system of galaxies is expanding.”

“Most certainly, some planets are not inhabited, but others are, and among these there must exist life under all conditions and phases of development.”

“Look at that! If you ever needed convincing that we live in the solar system, that we are on a ball of rock, orbiting around the Sun with other balls of rock, then look at that! That’s the solar system coming down and grabbing you by the throat.”

“Ultimately the galaxy, indeed the sum of the universe in its entirety, was mostly nothing; average it all out and it made a pretty good vacuum. But within the foci of matter there were the systems, the stars and planets and habitats—what a cornucopia of life was there!”

“I have to believe there's some other life force out there. I don't know in what form. But we can't have all these galaxies and universes without something going on. ”

“There seems to be no end to the senseless wickedness done on this little planet in a minor solar system, and we puny mortals appear to be decreasing in importance so far as the universe is concerned.”

“An observer studying the Solar system dispassionately, and finding himself capable of bringing the four giant planets to his notice, could reasonably say that the Solar system consisted of one star, four planets, and some traces of debris.”

“If the expansion of the space of the universe is uniform in all directions, an observer located in anyone of the galaxies will see all other galaxies running away from him at velocities proportional to their distances from the observer.”
