We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.
Carl Sagan (Cosmos)
Algebra applies to the clouds, the radiance of the star benefits the rose--no thinker would dare to say that the perfume of the hawthorn is useless to the constellations. Who could ever calculate the path of a molecule? How do we know that the creations of worlds are not determined by falling grains of sand? Who can understand the reciprocal ebb and flow of the infinitely great and the infinitely small, the echoing of causes in the abyss of being and the avalanches of creation? A mite has value; the small is great, the great is small. All is balanced in necessity; frightening vision for the mind. There are marvelous relations between beings and things, in this inexhaustible whole, from sun to grub, there is no scorn, each needs the other. Light does not carry terrestrial perfumes into the azure depths without knowing what it does with them; night distributes the stellar essence to the sleeping plants. Every bird that flies has the thread of the infinite in its claw. Germination includes the hatching of a meteor and the tap of a swallow's beak breaking the egg, and it guides the birth of the earthworm, and the advent of Socrates. Where the telescope ends, the microscope begins. Which of the two has a greater view? Choose. A bit of mold is a pleiad of flowers; a nebula is an anthill of stars. The same promiscuity, and still more wonderful, between the things of the intellect and material things. Elements and principles are mingled, combined, espoused, multiplied one by another, to the point that the material world, and the moral world are brought into the same light. Phenomena are perpetually folded back on themselves. In the vast cosmic changes, universal life comes and goes in unknown quantities, rolling everything up in the invisible mystery of the emanations, using everything, losing no dream from any single sleep, sowing a microscopic animal here, crumbling a star there, oscillating and gyrating, making a force of light, and an element of thought, disseminated and indivisible dissolving all, that geometric point, the self; reducing everything to the soul-atom; making everything blossom into God; entangling from the highest to the lowest, all activities in the obscurity of a dizzying mechanism, linking the flight of an insect to the movement of the earth, subordinating--who knows, if only by the identity of the law--the evolutions of the comet in the firmament to the circling of the protozoa in the drop of water. A machine made of mind. Enormous gearing, whose first motor is the gnat, and whose last is the zodiac.
Victor Hugo (Les Misérables)
They became upright and taught themselves the use of tools, domesticated other animals, plants and fire, and devised language. The ash of stellar alchemy was now emerging into consciousness. At an ever-accelerating pace, it invented writing, cities, art and science, and sent spaceships to the planets and the stars. These are some of the things that hydrogen atoms do, given fifteen billion years of cosmic evolution.
Carl Sagan (Cosmos)
An attempt to study the evolution of living organisms without reference to cytology would be as futile as an account of stellar evolution which ignored spectroscopy.
J.B.S. Haldane
Then, looking beyond the Earth itself to the magnificence of the larger scene, there was a startling recognition that the nature of the universe was not as I had been taught. My understanding of the separate distinctness and the relative independence of movement of those cosmic bodies was shattered. There was an upwelling of fresh insight coupled with a feeling of ubiquitous harmony-a sense of interconnectedness with the celestial bodies surrounding our spacecraft. Particular scientific facts about stellar evolution took on new significance.
Edgar D. Mitchell (The Way of the Explorer)
If you didn't already know, we're expecting in about four and a half months." Elliott beamed. The guests raised glasses with congratulations in the air. "He slipped one past a goalie!" Ryan cheered. The beer I just sipped came out through my nose. Mia was choking on her water. Serena turned from Ryan to Elliott, smacking him on the chest. Mortification painted her red face. "Did you teach him that?" Elliott shrugged with a mischievous grin.

Baby, you keep doing that and we are going to need Giana to get her ass in here to take care of baby girl." He palmed my ass. "Giana is already here." She knocked on the counter behind us. "Thank you, Jesus!" Though, Chris pronounced it Hey-Seuss. Bending, he lifted me onto his shoulder and took long strides to the staircase.
Sadie Grubor (Stellar Evolution (Falling Stars, #1.5))
I know that look." I put one arm out in from of me. He didn't stop. "Chris, we have to get going." I backed up, scooting over to put the couch between us. "What?" He feigned and innocent expression. "You know what." He kept coming. I continued evasive maneuvers. "They're going to be waiting on us." He shrugged. "It's not my wedding." His tongue darted out, wetting his bottom lip before sucking it back into his mouth. "I'd rather push that way too tight dress up around your waist and bend you over the couch.

B2FH traces these various fusion reactions and explains the recipe for producing everything up to iron: it’s nothing less than evolution for elements.
Sam Kean (The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements)
Connection with the world is built in to every aspect of our being. […] We’re joined to the cosmos and the everyday world as described by science in countless ways: the elements composing our bodies are the products of the Big Bang and stellar evolution; most of our DNA is shared with other beings; our perceptions and sensations are all mediated by processes involving photons, electrons, ions, neurotransmitters and other entirely physical entities; and our character and behavior is fully a function of genetics and environment. We are, therefore, fully linked with our surroundings in time, space, matter/energy, and causality. In fact, no more intimate connection with the totality of what is could be imagined. So, from a naturalistic perspective, there is an empirically valid referent for the sense of cosmic consciousness encountered in spiritual experience. The feeling of unity generated by (actually, identical to) the quieting of the orientation mechanisms in the brain mirrors the objective state of our complete interconnection with the world.
Thomas W. Clark
In the outer layers of young stars life nearly always appears not only in the normal manner but also in the form of parasites, minute independent organisms of fire, often no bigger than a cloud in the terrestrial air, but sometimes as large as the Earth itself. These "salamanders" either feed upon the welling energies of the star in the same manner as the star's own organic tissues feed, or simply prey upon those tissues themselves. Here as elsewhere the laws of biological evolution come into force, and in time there may appear races of intelligent flame-like beings. Even when the salamandrian life does not reach this level, its effect on the star's tissues may become evident to the star as a disease of its skin and sense organs, or even of its deeper tissues. It then experiences emotions not wholly unlike human fright and shame, and anxiously and most humanly guards its secret from the telepathic reach of its fellows. The salamandrian races have never been able to gain mastery over their fiery worlds. Many of them succumb, soon or late, either to some natural disaster or to internecine strife or to the self-cleansing activities of their mighty host. Many others survive, but in a relatively harmless state, troubling their stars only with a mild irritation, and a faint shade of insincerity in all their dealings with one another. In the public culture of the stars the salamandrian pest was completely ignored. Each star believed itself to be the only sufferer and the only sinner in the galaxy. One indirect effect the pest did have on stellar thought. It introduced the idea of purity. Each star prized the perfection of the stellar community all the more by reason of its own secret experience of impurity.
Olaf Stapledon (Star Maker)
For unknown ages after the explosive outpouring of matter and energy of the Big Bang, the Cosmos was without form. There were no galaxies, no planets, no life. Deep, impenetrable darkness was everywhere, hydrogen atoms in the void. Here and there, denser accumulations of gas were imperceptibly growing, globes of matter were condensing-hydrogen raindrops more massive than suns. Within these globes of gas was kindled the nuclear fire latent in matter. A first generation of stars was born, flooding the Cosmos with light. There were in those times, not yet any planets to receive the light, no living creatures to admire the radiance of the heavens. Deep in the stellar furnaces, the alchemy of nuclear fusion created heavy elements from the ashes of hydrogen burning, the atomic building blocks of future planets and lifeforms. Massive stars soon exhausted their stores of nuclear fuel. Rocked by colossal explosions, they returned most of their substance back into the thin gas from which they had once condensed. Here in the dark lush clouds between the stars, new raindrops made of many elements were forming, later generation of stars being born. Nearby, smaller raindrops grew, bodies far too little to ignite the nuclear fire, droplets in the interstellar mist on their way to form planets. Among them was a small world of stone and iron, the early Earth. Congealing and warming, the Earth released methane, ammonia, water and hydrogen gases that had been trapped within, forming the primitive atmosphere and the first oceans. Starlight from the Sun bathed and warmed the primeval Earth, drove storms, generated lightning and thunder. Volcanoes overflowed with lava. These processes disrupted molecules of the primitive atmosphere; the fragments fell back together into more and more complex forms, which dissolved into the early oceans. After a while the seas achieved the consistency of a warm, dilute soup. Molecules were organized, and complex chemical reactions driven, on the surface of clay. And one day a molecule arose that quite by accident was able to make crude copies of itself out of the other molecules in the broth. As time passed, more elaborate and more accurate self replicating molecules arose. Those combinations best suited to further replication were favored by the sieve of natural selection. Those that copied better produced more copies. And the primitive oceanic broth gradually grew thin as it was consumed by and transformed into complex condensations of self replicating organic molecules. Gradually, imperceptibly, life had begun. Single-celled plants evolved, and life began generating its own food. Photosynthesis transformed the atmosphere. Sex was invented. Once free living forms bonded together to make a complex cell with specialized functions. Chemical receptors evolved, and the Cosmos could taste and smell. One celled organisms evolved into multicellular colonies, elaborating their various parts into specialized organ systems. Eyes and ears evolved, and now the Cosmos could see and hear. Plants and animals discovered that land could support life. Organisms buzzed, crawled, scuttled, lumbered, glided, flapped, shimmied, climbed and soared. Colossal beasts thundered through steaming jungles. Small creatures emerged, born live instead of in hard-shelled containers, with a fluid like the early ocean coursing through their veins. They survived by swiftness and cunning. And then, only a moment ago, some small arboreal animals scampered down from the trees. They became upright and taught themselves the use of tools, domesticated other animals, plants and fire, and devised language. The ash of stellar alchemy was now emerging into consciousness. At an ever-accelerating pace, it invented writing, cities, art and science, and sent spaceships to the planets and the stars. These are some of the things that hydrogen atoms do, given fifteen billion years of cosmic evolution.

The Stellar Evolution of Cybersecurity. The evolutionary processes of stars depend upon their initial mass. The evolutionary processes of cybersecurity depend upon the hyperconvergence of Cyber Dependencies, People, Processes, and Technology.
Ludmila Morozova-Buss
We now know that the atoms in our bodies were forged in nuclear reactions in stellar furnaces, spewed into the universe in supernovae explosions, and incorporated into our bodies through the long process of the evolution of life over the last 3.8 billion years on Earth. We recognize that after death, our bodily atoms will be dispersed once again through the universe, recycled to once again become star stuff in a cycle of events that will end only with the death of the universe itself. We are part and parcel of the universe, and at the hour of our death when we return to the universe, the old phrase [...] “earth to earth, ashes to ashes, dust to dust” need only be slightly altered to “earth to earth, ashes to ashes, stardust to stardust” to be literally true. Cosmic evolution provides us with a master narrative in which our own birth, life, and death are integral parts of the universe, without recourse to the supernatural.
Steven J. Dick (Cosmos & Culture: Cultural Evolution in a Cosmic Context)
What if Soul #19,428,939,045 had failed the first 19 lifetimes and had it not been for the big renege and eternal damnation, on the 20th his goodness would have smacked the ball so far out of the park, with such profound benevolence and kindness for all, it would have permanently altered the course of human evolution, ushering in a golden age of caring and kindness so grand it’s not even conceivable on the present plane? Or let’s say it might have taken him 19 million times at bat before making such a mark in history. If eternal bliss lay beyond (mind you, that’s a very long time and a whole lot of bliss) for everyone, evermore? Suddenly 19 million times at bat becomes a pittance to pay for such stellar returns. As does 19 billion, or trillion, or zillion, given the inconceivable scope of eternity. The beautiful idea of God “loving humanity” so deeply that He gave us freedom is blown to smithereens on the day such freedom is taken back, considering that on that one day there could have been a breakthrough that now can never be. And we haven’t even posed the greatest of all questions that in a split second, if we even attempt to answer, obliterates the entire notion of hell and the devil: “Why?!
Mike Dooley (The Top Ten Things Dead People Want to Tell YOU: Answers to Inspire the Adventure of Your Life)
That’s crazy! We can’t go the way of—” “Since when has human history been anything else?” asks the woman with the camera on her shoulder—Donna, being some sort of public archivist, is in Sirhan’s estimate likely to be of use to him. “Remember what we found in the DMZ?” “The DMZ?” Sirhan asks, momentarily confused. “After we went through the router,” Pierre says grimly. “You tell him, love.” He looks at Amber. Sirhan, watching him, feels it fall into place at that moment, a sense that he’s stepped into an alternate universe, one where the woman who might have been his mother isn’t, where black is white, his kindly grandmother is the wicked witch of the west, and his feckless grandfather is a farsighted visionary. “We uploaded via the router,” Amber says, and looks confused for a moment. “There’s a network on the other side of it. We were told it was FTL, instantaneous, but I’m not so sure now. I think it’s something more complicated, like a lightspeed network, parts of which are threaded through wormholes that make it look FTL from our perspective. Anyway, Matrioshka brains, the end product of a technological singularity—they’re bandwidth-limited. Sooner or later the posthuman descendants evolve Economics 2.0, or 3.0, or something else, and it, uh, eats the original conscious instigators. Or uses them as currency or something. The end result we found is a howling wilderness of degenerate data, fractally compressed, postconscious processes running slower and slower as they trade storage space for processing power. We were”—she licks her lips—“lucky to escape with our minds. We only did it because of a friend. It’s like the main sequence in stellar evolution; once a G-type star starts burning helium and expands into a red giant, it’s ‘game over’ for life in what used to be its liquid-water zone.
Charles Stross (Accelerando)
While a star is on the main sequence, it makes only helium. A star leaves the main sequence when it exhausts the supply of available hydrogen in its core. The post-main sequence fate of the star, and the range of elements produced, depends on the mass of the star. The lowest mass M stars, roughly below .2 Solar masses, are well mixed and can always bring hydrogen from outer layers to the core to sustain fusion. Such stars become gradually more luminous over trillions of years as they convert their hydrogen into helium, until they exhaust their fuel and fade away as white dwarf stars. White dwarf stars are no longer producing energy by fusion. Because of contraction, their surface temperatures are high (hence their bluish-white colour), but they have low luminosity because they are very small. White dwarfs are a common form of stellar remnant. All white dwarfs eventually cool down and go dark, but this process takes many times the current age of the Universe.
Raymond T. Pierrehumbert (Planetary Systems: A Very Short Introduction (Very Short Introductions))
Although the first stars of the Universe could not have formed planetary systems, the process did not take long to get underway. Because massive stars are short-lived, the first billion years of the Universe already had time for 1,000 generations of production of the heavier elements. Observations show that the early universe was already a quite dusty place. Although massive stars do not live long enough to host planetary systems where life is likely to emerge, they are essential to producing the elements that lower-mass systems use to build habitable worlds. The Milky Way galaxy, our home, formed not long after the Big Bang, and has been building its stock of heavy elements ever since. Most of this galactic chemical evolution remains internal to the galaxy, although galaxies do sometimes collide and exchange material. Over the past thirteen billion years of nucleosynthesis in the Milky Way, there has been ample time for thorough mixing across the galaxy. Thus, our Solar System incorporates ingredients from a mix of myriad expired stars, most of which have been processed multiple times through short-lived stars. Every breath you take includes oxygen atoms from thousands of different stars that have lived and died in our galaxy over the past thirteen billion years.
Raymond T. Pierrehumbert (Planetary Systems: A Very Short Introduction (Very Short Introductions))
We are experts of the physical galaxy. We live on terraformed worlds and in massive orbital habitats. We tunnel through the sublayer to hop between stellar systems. We escape planetary gravity with the ease of walking out the front door. But when it comes to evolution, we are hatchlings, fumbling with toys. I believe this is why many of my peers still cling to theories of genetic material scattered by asteroids and supernovae. In many ways, the idea of a shared stock of genes drifting through the galaxy is far easier to accept than the daunting notion that none of us may ever have the intellectual capacity to understand how life truly works.

E questo non è neanche lo scenario peggiore” continuò Hassan. “L’altra possibilità è che trovi un modo per mettersi in contatto con altre entità aliene.” Fece una breve pausa drammatica. “Quelle che vanno in cerca di specie evolute per prenderne il controllo.
Rita Carla Francesca Monticelli (Nave stellare Aurora)
Early on, advocates of big bang cosmology realized that the universe is evolutionary. In the words of one famous cosmologist, George Gamov, “We conclude that the relative abundances of atomic species represent the most ancient archaeological document pertaining to the history of the universe.” In other words, the periodic table is evidence of the evolution of matter, and atoms can testify to the history of the cosmos. But early versions of big bang cosmology held that all the elements of the universe were fused in one fell swoop. As Gamov puts it, “These abundances …” meaning the ratio of the elements (heaps of hydrogen, hardly any gold—that kind of thing), “… must have been established during the earliest stages of expansion, when the temperature of the primordial matter was still sufficiently high to permit nuclear transformations to run through the entire range of chemical elements.” It was a neat idea, but very wrong. Only hydrogen, helium, and a dash of lithium could have formed in the big bang. All of the elements heavier than lithium were made much later, by being fused in evolving and exploding stars. How do we know this? Because at the same time some scholars were working on the big bang theory, others were trying to ditch the big bang altogether. Its association with thermonuclear devices made it seem hasty, and its implied mysterious origins tainted it with creationism. And so, a rival camp of cosmologists developed an alternate theory: the Steady State. The Steady State held that the universe had always existed. And always will. Matter is created out of the vacuum of space itself. Steady State theorists, working against the big bang and its flaws, were obliged to wonder where in the cosmos the chemical elements might have been cooked up, if not in the first few minutes of the universe. Their answer: in the furnaces of the very stars themselves. They found a series of nuclear chain reactions at work in the stars. First, they discovered how fusion had made elements heavier than carbon. Then, they detailed eight fusion reactions through which stars convert light elements into heavy ones, to be recycled into space through stellar winds and supernovae. And so, it’s the inside of stars where the alchemist’s dream comes true. Every gram of gold began billions of years ago, forged out of the inside of an exploding star in a supernova. The gold particles lost into space from the explosion mixed with rocks and dust to form part of the early Earth. They’ve been lying in wait ever since.
Mark Brake (The Science of Harry Potter: The Spellbinding Science Behind the Magic, Gadgets, Potions, and More!)
Thus, though there is normally no such thing as sin among the stars, no deliberate choice of the course known to be wrong for the sake of some end known to be irrelevant, there is ignorance, and consequent aberration from the pattern of the ideal as revealed to stars of somewhat maturer mentality.
Olaf Stapledon (Star Maker)
