I know I said some things about needing space, but you are not the moon or the sun, a planet or a dwarf star. I do not know if distance from you will ever sit right with me.
Trista Mateer (Honeybee)
Have you heard about the demotion of the planet Pluto? I, for one, am incensed. How do you go your whole life being a planet and then, suddenly, you’re not a planet anymore. Correction: dwarf planet. What does that even mean? I see an idiom taking shape. Five, ten years from now, when someone gets dissed or demoted or loses his or her job, people will say, “He was plutoed.” “Are you plutoing me?” someone will say when witnessing a snub. “That was some pluto, wasn’t it?” Hmm, I’m not sure about the syntax of the last one, but I think you get the gist.
Lisa Lutz (How to Start a Fire)
How many times, by God’s bloody prick, have I longed to be able to detonate planets, to destroy the sun itself, to pluck it from the universe and crash it into the earth, annihilating all Creation and replacing it with a lightless void of violence. Ah, that would be a crime! A cosmic crime, dwarfing the petty misdemeanours we are committing here, limited as we are to snuffing out a few meaningless souls
Marquis de Sade (The 120 Days of Sodom)
n every culture, the sky and the religious impulse are intertwined. I lie back in an open field and the sky surrounds me. I’m overpowered by its scale. It’s so vast and so far away that my own insignificance becomes palpable. But I don’t feel rejected by the sky. I’m a part of it - tiny, to be sure, but everything is tiny compared to that overwhelming immensity. And when I concentrate in the stars, the planets, and their motions, I have an irresistible sense of machinery, clockwork, elegant precision working on a scale that, however lofty out aspirations, dwarfs and humbles us.
Carl Sagan (Pale Blue Dot: A Vision of the Human Future in Space)
AMAZONGOOGLEFACE ANNOUNCES INTENT TO ACQUIRE DISNEYAPPLESOFT The deal would result in a combined company worth approximately $97.3 quadrillion. "This will be good for consumers," said Jeff Bezos, CEO of AmazonGoogleFace, speaking from the company's offices on an icy dwarf planet in the Kuiper Belt.
Charles Yu (A People's Future of the United States: Speculative Fiction from 25 Extraordinary Writers)
The Observable world. According to the Big Bang theory, the universe came into being in one single moment – a cosmic cataclysm that gave birth to black hole, brown dwarfs, matter and dark matter, energy and dark energy. It gave birth to galaxies and stars and moons and suns and planets and oceans. It’s a hard concept to hold on to – the idea that there was a time before us. A time before time. In the beginning there was nothing. And then there was everything.
Nicola Yoon (Everything, Everything)
There’s a kind of theology at work here. The bombs are a kind of god. As his power grows, our fear naturally increases. I get as apprehensive as anyone else, maybe more so. We have too many bombs. They have too many bombs. There’s a kind of theology of fear that comes out of this. We begin to capitulate to the overwhelming presence. It’s so powerful. It dwarfs us so much. We say let the god have his way. He’s so much more powerful than we are. Let it happen, whatever he ordains. It used to be that the gods punished men by using the forces of nature against them or by arousing them to take up their weapons and destroy each other. Now god is the force of nature itself, the fusion of tritium and deuterium. Now he’s the weapon. So maybe this time we went too far in creating a being of omnipotent power. All this hardware. Fantastic stockpiles of hardware. The big danger is that we’ll surrender to the sense of inevitability and start flinging mud all over the planet.
Don DeLillo (End Zone)
When word of the astronomers’ vote in Prague reached the New Horizons team, reactions ranged from indifferent (“Who cares what astronomers think? They’re not the experts in this.”), to bemused, to annoyed, to seriously pissed off. As Fran Bagenal succinctly put it, “Dwarf people are people. Dwarf planets are planets. End of argument.
Alan Stern (Chasing New Horizons: Inside the Epic First Mission to Pluto)
It felt as if a shaft of lightning had gone in through one ear and out the other...Armies of dead men went marching through my head. I heard a noise like a cosmic scream. My brain turned to ice. Then the ice cracked in all directions and disintegrated into tiny particles like snowflakes, and each snowflake was afflicted by a pain of its very own. In the end, everything went black. I found myself looking out into the universe. Seated on a diminutive planet made of glass was a red dwarf who had twelve important messages for me.
Walter Moers (The 13½ Lives of Captain Bluebear (Zamonia, #1))
The Atlantic is a stormy moat, and the Mediterranean, The blue pool in the old garden, More than five thousand years has drunk sacrifice Of ships and blood and shines in the sun; but here the Pacific: The ships, planes, wars are perfectly irrelevant. Neither our present blood-feud with the brave dwarfs Nor any future world-quarrel of westering And eastering man, the bloody migrations, greed of power, battle-falcons, Are a mote of dust in the great scale-pan. Here from this mountain shore, headland beyond stormy headland plunging like dolphins through the grey sea-smoke Into pale sea, look west at the hill of water: it is half the planet: this dome, this half-globe, this bulging Eyeball of water, arched over to Asia, Australia and white Antarctica: those are the eyelids that never close; this is the staring unsleeping Eye of the earth, and what it watches is not our wars.
Robinson Jeffers (The Selected Poetry)
A dwarf blacksmith from another planet is using a magical anvil.” “So glad it isn’t something weird.

It’s the wretched contradiction of parenting. Once, you were their favorite human on the planet, and they were yours. For the rest of your life, your child will remain your heart . . . but it’s not mutual. It’s not supposed to be. Your importance is dwarfed by their friends. Romantic interests. Cool professors and great coaches. A spouse, someday, and kids of their own, and you . . . you got left behind at a certain exit on the highway of their life, and all you can do is look down the road after them and remember when you were so needed, so loved, so sure of your place in the world, because you were Mommy, and that was everything.
Kristan Higgins (Out of the Clear Blue Sky)
Unless some nuclear or ecological catastrophe intervenes, so goes the story, the pace of technological development will soon lead to the replacement of Homo sapiens by completely different beings who possess not only different physiques, but also very different cognitive and emotional worlds. This is something most Sapiens find extremely disconcerting. We like to believe that in the future people just like us will travel from planet to planet in fast spaceships. We don’t like to contemplate the possibility that in the future, beings with emotions and identities like ours will no longer exist, and our place will be taken by alien life forms whose abilities dwarf our own.

The Frankenstein myth confronts Homo Sapiens with the fact that the last days are fast approaching.

Yuval Noah Harari (Sapiens: A Brief History of Humankind)
On average, once every few hundred years the Earth is hit by an object about 70 meters in diameter; the resulting energy released is equivalent to the largest nuclear weapons explosion ever detonated. Every 10,000 years, we’re hit by a 200-meter object that might induce serious regional climatic effects. Every million years, an impact by a body over 2 kilometers in diameter occurs, equivalent to nearly a million megatons of TNT—an explosion that would work a global catastrophe, killing (unless unprecedented precautions were taken) a significant fraction of the human species. A million megatons of TNT is 100 times the explosive yield of all the nuclear weapons on the planet, if simultaneously blown up. Dwarfing even this, in a hundred million years or so, you can bet on something like the Cretaceous-Tertiary event, the impact of a world 10 kilometers across or bigger. The destructive energy latent in a large near-Earth asteroid dwarfs anything else the human species can get its hands on.
Carl Sagan (Pale Blue Dot)
However, this sceptic had one fanaticism. This fanaticism was neither a dogma, nor an idea, nor an art, nor a science; it was a man: Enjolras. Grantaire admired, loved, and venerated Enjolras. To whom did this anarchical scoffer unite himself in this phalanx of absolute minds? To the most absolute. In what manner had Enjolras subjugated him? By Free eBooks at Planet eBook.com 1119 his ideas? No. By his character. A phenomenon which is often observable. A sceptic who adheres to a believer is as simple as the law of complementary colors. That which we lack attracts us. No one loves the light like the blind man. The dwarf adores the drum-major. The toad always has his eyes fixed on heaven. Why? In order to watch the bird in its flight. Grantaire, in whom writhed doubt, loved to watch faith soar in Enjolras. He had need of Enjolras. That chaste, healthy, firm, upright, hard, candid nature charmed him, without his being clearly aware of it, and without the idea of explaining it to himself having occurred to him. He admired his opposite by instinct. His soft, yielding, dislocated, sickly, shapeless ideas attached themselves to Enjolras as to a spinal column. His moral backbone leaned on that firmness. Grantaire in the presence of Enjolras became some one once more. He was, himself, moreover, composed of two elements, which were, to all appearance, incompatible. He was ironical and cordial. His indifference loved. His mind could get along without belief, but his heart could not get along without friendship. A profound contradiction; for an affection is a conviction. His nature was thus constituted. There are men who seem to be born to be the reverse, the obverse, the wrong side. They are Pollux, Patrocles, Nisus, Eudamidas, Ephestion, Pechmeja. They only exist on condition that they are backed up with another man; their name is a sequel, and is only written preceded by the conjunction and; and their existence is not their own; it is the other side of an existence which is not theirs. Grantaire was one of these men. He was the obverse of Enjolras

FALL, SIERRA NEVADA This morning the hermit thrush was absent at breakfast, His place was taken by a family of chickadees; At noon a flock of humming birds passed south, Whirling in the wind up over the saddle between Ritter and Banner, following the migration lane Of the Sierra crest southward to Guatemala. All day cloud shadows have moved over the face of the mountain, The shadow of a golden eagle weaving between them Over the face of the glacier. At sunset the half-moon rides on the bent back of the Scorpion, The Great Bear kneels on the mountain. Ten degrees below the moon Venus sets in the haze arising from the Great Valley. Jupiter, in opposition to the sun, rises in the alpenglow Between the burnt peaks. The ventriloquial belling Of an owl mingles with the bells of the waterfall. Now there is distant thunder on the east wind. The east face of the mountain above me Is lit with far off lightnings and the sky Above the pass blazes momentarily like an aurora. It is storming in the White Mountains, On the arid fourteen-thousand-foot peaks; Rain is falling on the narrow gray ranges And dark sedge meadows and white salt flats of Nevada. Just before moonset a small dense cumulus cloud, Gleaming like a grape cluster of metal, Moves over the Sierra crest and grows down the westward slope. Frost, the color and quality of the cloud, Lies over all the marsh below my campsite. The wiry clumps of dwarfed whitebark pines Are smoky and indistinct in the moonlight, Only their shadows are really visible. The lake is immobile and holds the stars And the peaks deep in itself without a quiver. In the shallows the geometrical tendrils of ice Spread their wonderful mathematics in silence. All night the eyes of deer shine for an instant As they cross the radius of my firelight. In the morning the trail will look like a sheep driveway, All the tracks will point down to the lower canyon. “Thus,” says Tyndall, “the concerns of this little place Are changed and fashioned by the obliquity of the earth’s axis, The chain of dependence which runs through creation, And links the roll of a planet alike with the interests Of marmots and of men.
Kenneth Rexroth (Collected Shorter Poems)
Once settled on another planet, colonists would likely start with hydroponic farming, using small-stature or dwarf cultivars that can be tightly packed together. It would make the most sense to plant fast-cycle salad crops first, says Jean Hunter, a professor at Cornell who studies food-processing and waste-management systems for long-term living away from Earth.

His eyes widened and he rapidly scanned page after page. There were many photographs, each followed by detailed diagrams of the internal structure of the various neutron stars. They ranged the gamut from very dense stars that were almost black holes to large bloated neutron stars that had a neutron core and a white-dwarf-star exterior. Some of the names were unfamiliar, but others, like the Vela pulsar and the Crab Nebula pulsar, were neutron stars known to the humans. “But the Crab Nebula pulsar is over 3000 light-years away!” Pierre exclaimed to himself. “They would have had to travel faster than the speed of light to have gone there to take those photographs in the past eight hours!” A quick search through the index found the answer.

Let me play my hand, if you haven’t seen it already. My goal in this book is to convince you that your church and its slate of programs and ministries—no matter how successful they have been in attracting people—should be centered on the good news of the finished work of Jesus Christ. The attractional model cannot be the foundation for your methods and programs. It must give way to the gospel because the gospel is where the power of God is manifest. The gospel swallows up our pragmatic paradigms like a white dwarf swallows planets. Pragmatism has a place, but it’s not at the center. We must be gospel centered.
Jared C. Wilson (The Gospel-Driven Church: Uniting Church Growth Dreams with the Metrics of Grace)
Assembling Novopangaea is a tricky game. It’s easy to take today’s continental movements and predict ten or twenty million years down the road. The Atlantic will have widened by several hundred miles, while the Pacific will have shrunk by an equal amount. Australia will have moved north toward South Asia, and Antarctica will have shifted slightly away from the South Pole, also in the direction of South Asia. Africa is also on the move, inching northward to close off the Mediterranean Sea. In a few tens of millions of years, Africa will have collided with southern Europe, in the process closing up the Mediterranean and pushing up a Himalayan-size mountain range that will dwarf the Alps. So the map of the world twenty million years hence will appear familiar but skewed. Looking as far as one hundred million years into the future in this way is fairly safe, and most modelers arrive at similar geographies of a world where the Atlantic Ocean has overtaken the Pacific as the grandest body of water on Earth.

The galaxy is a place of laws. Gravity follows laws. The lifecycles of stars and planetary systems follow laws. Subatomic particles follow laws. We know the exact conditions that will cause the formation of a red dwarf, or a comet, or a black hole.

Pluto was once considered a complete planet but in 2006 it was redefined as a dwarf planet.

I tell her I’ve missed her, and she asks me what specifically I’ve missed. ‘I got all my scientific facts from you, for one thing. ‘I’m a total brain because of the information you gave me. Ask me a question. I’ll prove it.’ ‘Name the nine planets,’ she says. She watches me thinking. ‘You look like you’re in pain.’ ‘That’s my look of absolute genius. You don’t have a similar look?’ ‘I hope not,’ she says. ‘Well, that probably means you’re not an absolute genius. Okay. Nine planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.’ ‘That’s eight.’ ‘Thanks to information you gave me in Year 7, I know that was a trick question. There are only eight planets. Pluto is a dwarf planet.’ ‘Impressive,’ she says. ‘You should kiss me.’ ‘I should name the eight planets more often.

Twenty-three red dwarfs were listed. Eight of these were double. Eleven hung solitary in space, forlorn feeble sparks. Four were accompanied by planets, eight planets in all. These four Gersen scrutinized with special care. Reluctantly he was forced to conclude that none of these planets could conceivably be considered habitable. Five of the planets were too hot, one was completely awash in liquid methane, two were too massive to allow human toleration of the gravity. Gersen’s mouth drooped in disappointment. Nothing. Still, the page at one time had been earnestly consulted: there must be information here which Dasce needed or valued. Gersen tore the page from the book.

The assessment will be guided by insights from research in particle physics, astrophysics, and cosmology that allow us to predict how the universe will unfold over epochs that dwarf the timeline back to the bang. There are significant uncertainties, of course, and like most scientists I live for the possibility that nature will slap down our hubris and reveal surprises we can’t yet fathom. But focusing on what we’ve measured, on what we’ve observed, and on what we’ve calculated, what we’ll find, as laid out in chapters 9 and 10, is not heartening. Planets and stars and solar systems and galaxies and even black holes are transitory. The end of each is driven by its own distinctive combination of physical processes, spanning quantum mechanics through general relativity, ultimately yielding a mist of particles drifting through a cold and quiet cosmos. How will conscious thought fare in a universe experiencing such transformation? The language for asking and answering this question is provided once again by entropy. And by following the entropic trail we will encounter the all-too-real possibility that the very act of thinking, undertaken by any entity of any kind anywhere, may be thwarted by an unavoidable buildup of environmental waste: in the distant future, anything that thinks may burn up in the heat generated by its own thoughts. Thought itself may become physically impossible. While the case against endless thought will be based on a conservative set of assumptions, we will also consider alternatives, possible futures more conducive to life and thinking. But the most straightforward reading suggests that life, and intelligent life in particular, is ephemeral. The interval on the cosmic timeline in which conditions allow for the existence of self-reflective beings may well be extremely narrow. Take a cursory glance at the whole shebang, and you might miss life entirely. Nabokov’s description of a human life as a “brief crack of light between two eternities of darkness”6 may apply to the phenomenon of life itself. We mourn our transience and take comfort in a symbolic transcendence, the legacy of having participated in the journey at all. You and I won’t be here, but others will, and what you and I do, what you and I create, what you and I leave behind contributes to what will be and how future life will live. But in a universe that will ultimately be devoid of life and consciousness, even a symbolic legacy—a whisper intended for our distant descendants—will disappear into the void. Where, then, does that leave us?
Brian Greene (Until the End of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe)
I'm incapable of doing anything right, so I must have wished upon the wrong star. Or I got it so wrong I actually missed the stars altogether and wished upon Pluto, because just like that dwarf planet, I also wasn't good enough to make the cut.
Philippa Young
Smade’s Planet was the single companion of Smade’s Star, an undistinguished white dwarf in a relatively empty region of space. The native flora was sparse: lichen, moss, primitive vines and palodendron, pelagic algae which tinctured the sea black. The fauna was even simpler: white worms in the sea-bottom muck; a few gelatinous creatures which gathered and ingested the black algae in a ludicrously inept fashion; an assortment of simple protozoa. Smade’s alterations of the planet’s ecology could hardly, therefore, be considered detrimental.
Jack Vance (Demon Princes (Demon Princes #1-5))
In the Atacama, I saw the future, when the sun eats up the last of its hydrogen and burns into its red-giant phase, big enough to cook life and clouds and oceans off this naked orb. It wouldn't be a fast process, not by our standards. Millions of years in the execution, our sky would finally be half filled by a sun the color of a red-hot moonrise. After that, the sun would probably collapse into a white dwarf, meanwhile blasting away its outer shells of gas into an explosive planetary nebula. I imagine that all of our minerals will pay off as we make a rainbow streak flaring off into space. We will be beautiful.
Craig Childs (Apocalyptic Planet: Field Guide to the Ever-Ending Earth)
Over half of the mass in the asteroid belt is contained in four asteroids and dwarf planets: Ceres, Vesta, Pallas, and Hygiea. The largest, by a wide margin, is Ceres. It contains almost one third of all the mass in the asteroid belt.

In the end, the most disastrous consequence of the building of the nuclear pyramid may turn out to be not nuclear weapons themselves or some irretrievable act of extermination that they may bring about. Something even worse may be in store, and should it go far enough, be equally irretrievable: namely, the universal imposition of the megamachine, in a perfected form, as the ultimate instrument of pure 'intelligence,' whereby every other manifestation of human potentialities will be suppressed or completely eliminated. Already the blueprints for that final structure are available: they have even been advertised as man's highest destiny. Yet happily for mankind the megamachine itself is in trouble, largely because of its early dependence upon the nuclear bomb. for the very concept of wielding absolute power has set a collective trap, so delicately balanced that its mechanism has more than once been on the point of snapping down on its appointed victims, the inhabitants of the planet. Had that happened, the megamachine would have shattered its own structure as well. Over the entire Pentagon of Power, thanks to the technocratic arrogance and automated intelligence of those who have built this citadel, hovers a nuclear Ragnarok, a Twilight of the Gods, long ago predicted in Norse mythology: a world consumed in flames, when all things human and divine would be overcome by the cunning dwarfs and the brutal giants. After the Sixth Dynasty the Pyramid Age in Egypt came to an end in a violent popular uprising, even without any such cosmic disruption. And something less than the Norse nightmare, though no less ominous to the megamachine, may be in store-or is it now perhaps actually taking place?

The latest research clearly suggests that a magnetic field of some kind is a requirement for planets to be habitable [2].
Mathew Anderson (Habitable Exoplanets: Red Dwarf Systems Like TRAPPIST-1)
minimum mass of a planet to sustain features like an intrinsic magnetic field and a habitable atmosphere in a star’s habitable zone is about 1/3 the mass of the Earth [5]. Mars has 1/10th the mass of the Earth, and thus is the leading reason why the planet is in such a desiccated state today.
Mathew Anderson (Habitable Exoplanets: Red Dwarf Systems Like TRAPPIST-1)
if life first became viable after the early bombardment era ended 3.8 billion years ago, we are now almost three-quarters of the way through Earth’s habitable period. Nevertheless, we should be grateful for the great wealth of time that this planet has had as a consequence of belonging to a yellow dwarf star with a lifetime of 10 billion years. Stars just 50% larger than the Sun have a life expectancy of only 3 billion years, which on Earth would be equivalent to the time span from the formation of the planet to the middle of the Boring Billion.

Our solar system, in turn, is just one tiny corner of the Milky Way galaxy, that thick band of stars visible in the darkest night skies stretching far over our heads. We’re about 25,000 light-years away from the center of the rotating galaxy, which astronomers estimate contains somewhere between 100 and 400 billion stars—and at least that number of planets—and stretches across some 87,400 light-years. What we see in our skies from Earth is the equivalent of staring at the side of the Milky Way stretching off before us, as if we’re looking at the edge of a plate or a Frisbee. It is spiral-shaped, like an enormous spinning pinwheel, first mentioned, as far as we know, by the Persian astronomer Abd al-Rahman al-Sufi in AD 964, recorded in his The Book of the Fixed Stars. In 1610, Galileo was the first astronomer to piece together, using a telescope, that the Milky Way visible in our skies was a collection of faint stars; a century later, Immanuel Kant surmised that it was a rotating body of stars, and over the next two hundred years, astronomers came to begin to grasp how enormous the universe truly is. Now we understand that our Milky Way is about 2.5 million light-years from the next closest galaxy, known as Andromeda. Together, these two massive galaxies—and all the stuff in between them, including a number of so-called dwarf galaxies and satellite galaxies, as well as a third large galaxy known as Triangulum—make up what astronomers call the “Local Group,” which is one corner of a larger cosmic structure known as a “supercluster.”II For most of the last fifty years, our particular galactic neighborhood was believed to be part of the “Virgo Supercluster,” a gathering of about one hundred galaxies, but in 2014 a team of astronomers led by Hawaii’s R. Brent Tully realized we were more connected to our neighbors than anyone had realized; they redrew the boundaries of the galactic map after realizing that our supercluster was far more vast and in fact consisted of what had been four separate superclusters that all moved in the same gravitational rhythm. They dubbed the new supercluster “Laniakea,” Hawaiian for “immense heaven,” and we now believe it encompasses about one hundred thousand other galaxies that astronomers define as “nearby,” despite the fact that they stretch across more than 520 million light-years of outer space. Laniakea, in turn, is now understood to be part of the Pisces-Cetus Supercluster Complex, an enormous structure of about sixty superclusters that together stretch across a billion light-years. The Pisces-Cetus Supercluster Complex is what’s known as a “galaxy filament,” the largest structures known to exist in our universe, in which NASA now estimates there are about 200 billion galaxies stretching across 46 billion light-years.III (Each of those galaxies is estimated to have perhaps 100 million stars—although the largest, known as supergiants, can contain 100 trillion.)
