1 " I’ll never understand why some people can’t just let others live their lives, you know,” Danial said. “You don’t have to understand. You don’t have to agree. Just leave people alone. When I look at the moon and planets and stars, all that narrow-mindedness and hate seem so petty. The universe is such a big place. One hundred thousand light years just from one end of the Milky Way to the other. One hundred. Thousand. Light years. In the time it’s taken for light to travel from one end of our galaxy to the other, thousands of generations have passed. It really makes you realize how small we are, doesn’t it? How short our time on earth is. "

2 " Mr. McCleod: And if there’s anything I want you guys to take with you from this class, as you’re abusing your bodies over break, is three things: the heart is the body’s strongest muscle, that the brain has more cells in it than our galaxy has stars, and that the body is 72% water. So wherever you go over vacation, don’t get too dehydrated. "

3 " One thing seems certain. Our galaxy is now in the brief springtime of its life—a springtime made glorious by such brilliant blue-white stars as Vega and Sirius, and, on a more humble scale, our own Sun. Not until all these have flamed through their incandescent youth, in a few fleeting billions of years, will the real history of the universe begin.It will be a history illuminated only by the reds and infrareds of dully glowing stars that would be almost invisible to our eyes; yet the sombre hues of that all-but-eternal universe may be full of colour and beauty to whatever strange beings have adapted to it. They will know that before them lie, not the millions of years in which we measure eras of geology, nor the billions of years which span the past lives of the stars, but years to be counted literally in the trillions.They will have time enough, in those endless aeons, to attempt all things, and to gather all knowledge. They will be like gods, because no gods imagined by our minds have ever possessed the powers they will command. But for all that, they may envy us, basking in the bright afterglow of creation; for we knew the universe when it was young. "
― Arthur C. Clarke
4 " The glow lasted through the night, beyond the bar's closing, when there were no cabs on the street. And so Mathilde and Lotto decided to walk home, her arm in his, chatting about nothing, about everything, the unpleasant, hot breath of the subway belching up from the grates. 'Chthonic', he said, booze letting loose the pretension at his core, which she still found sweet, an allowance from the glory. It was so late, there were few other people out, and it felt, just for this moment, that they had the city to themselves.She thought of all the life just underfoot, the teem of it that they were passing over, unknowing. She said, 'Did you know that the total weight of all the ants on Earth is the same as the total weight of all the humans on Earth.' She, who drank to excess, was a little bit drunk, it was true, there was so much relief in the evening.When the curtains closed against the backdrop, an enormous bolder blocking their future had rolled away.'They'll still be here when we're gone,' he said. He was drinking from a flask. By the time they were home, he'd be sozzeled. 'The ants and the jellyfish and the cockroaches, they will be the kings of the Earth.'...'They deserve this place more than we do,' she said. 'We've been reckless with our gifts.' He smiled and looked up. There were no stars, there was too much smog for them.'Did you know,' he said, 'they just found out just a while ago that there are billions of worlds that can support life in our galaxy alone.'...She felt a sting behind here eyes, but couldn't say why this thought touched her.He saw clear through and understood. He knew her. The things he didn't know about her would sink an ocean liner. He knew her.'We're lonely down here,' he said, 'it's true, but we're not alone.'In the hazy space after he died, when she lived in a sort of timeless underground grief, she saw on the internet a video about what would happen to our galaxy in billions of years. We are in an immensely slow tango with the Andromeda galaxy, both galaxies shaped like spirals with outstretched arms, and we are moving toward each other like spinning bodies. The galaxies will gain speed as they draw near, casting off blue sparks, new stars until they spin past each other, and then the long arms of both galaxies will reach longingly out and grasp hands at the last moment and they will come spinning back in the opposite direction, their legs entwined, never hitting, until the second swirl becomes a clutch, a dip, a kiss, and then at the very center of things, when they are at their closest, there will open a supermassive black hole.

5 " The biblical account of the origin of the cosmos in Genesis, for example, posits that a god created the physical universe particularly with human beings in mind, and so unsurprisingly placed the Earth at the center of creation.Modern cosmological knowledge has refuted such an account. We are living in the golden age of cosmology: More has been discovered about the large-scale structure and history of the visible cosmos in the last 20 years than in the whole of prior human history. We now have precise knowledge of the distribution of galaxies and know that ours is nowhere near the center of the universe, just as we know that our planetary system has no privileged place among the billions of such systems in our galaxy and that Earth is not even at the center of our planetary system. We also know that the Big Bang, the beginning of our universe, occurred about 13.7 billion years ago, whereas Earth didn’t even exist until about 10 billion years "
6 " The math is dead simple: it seems that the frequency of planets able to support life is roughly one percent. In other words, a billion or more such worlds exist in our galaxy alone. That's a lot of acreage, and it takes industrial-strength credulity to believe it's all bleakly barren. "
7 " Is it not careless to become too local when there are four hundred billion stars in our galaxy alone. "
