Entropy Universe Quotes

Entropy requires no maintenance.

Just as the constant increase of entropy is the basic law of the universe, so it is the basic law of life to be ever more highly structured and to struggle against entropy.

People are, at their heart, constantly moving toward a state of entropy. Much like this ship. We’re all spiraling out of control.

Strange department, this. Their motto was: "The comprehension of Infinity requires infinite time." I did not argue with that, but then they derived an unexpected conclusion from it: Therefore work or not, it´s all the same." In the interests of not increasing the entropy of the universe, they did not work.

Nor public flame, nor private, dares to shine; Nor human spark is left, nor glimpse divine! Lo! thy dread empire, Chaos! is restored; Light dies before thy uncreating word: Thy hand, great Anarch! lets the curtain fall; And universal darkness buries all.

Chaos was the natural law of the universe. Indifference was the engine of entropy. Man's apathy was the fertile ground in which the dark spirits tended their seeds.

And it came to pass that AC learned how to reverse the direction of entropy. But there was now no man to whom AC might give the answer of the last question. No matter. The answer--by demonstration--would take care of that, too. For another timeless interval, AC thought how best to do this. Carefully, AC organized the program. The consciousness of AC encompassed all of what had been a Universe and brooded over what was now Chaos. Step by step, it must be done. And AC said, "LET THERE BE LIGHT!" And there was light--

Those swirls in the cream mixing into the coffee? That’s us. Ephemeral patterns of complexity, riding a wave of increasing entropy from simple beginnings to a simple end. We should enjoy the ride.

In an expanding universe, Spencer had said, order was not really order, but merely the difference between the actual entropy exhibited and the maximum entropy possible.

We exist with or without God. We are the inevitable result of entropy. Life is not the point of the universe. Life is simply what the universe creates and reproduces in order to dissipate energy.

The difference is that the heat energy we radiate is a high-entropy form of energy, meaning it’s disordered. The chemical energy we absorb is a low-entropy form of energy, meaning it’s ordered. In effect, we are consuming order and generating disorder; we live by increasing the disorder of the universe. It’s only because the universe started in a highly ordered state that we are able to exist at all.

Somehow, after all, as the universe ebbs toward its final equilibrium in the featureless heat bath of maximum entropy, it manages to create interesting structures.

It sometimes seems as if curbing entropy is our quixotic purpose in this universe.

The fundamental laws of the universe which correspond to the two fundamental theorems of the mechanical theory of heat. 1. The energy of the universe is constant. 2. The entropy of the universe tends to a maximum.

The universe seeks equilibriums; it prefers to disperse energy, disrupt organization, and maximize chaos. Life is designed to combat these forces. We slow down reactions, concentrate matter, and organize chemicals into compartments; we sort laundry on Wednesdays. "It sometimes seems as if curbing entropy is our quixotic purpose in the universe," James Gleick wrote. We live in the loopholes of natural laws, seeking extensions, exceptions and excuses. The laws of nature still mark the outer boundaries of permissibility - but life, in all its idiosyncratic, mad weirdness, flourishes by reading between the lines.

The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations - then so much the worse for Maxwell's equations. If it is found to be contradicted by observation - well, these experimentalists do bungle things sometimes. But if your theory is found to be against the Second Law of Thermodynamics I can give you no hope; there is nothing for it to collapse in deepest humiliation.

One thinks one’s something unique and wonderful at the center of the universe. But in fact one’s merely a slight delay in the ongoing march of entropy.

Some say Karma is a bitch. It all comes back to you, eventually. If this world can be boiled down to two truths. It would be the second law of thermodynamics (entropy) and the law of action and reaction (Karma). Well, if Karma really makes up the fabric of this Universe, if it is really a bitch, then prove it in this life itself! Why wait for reincarnation? Do you think I would be me once I die and transition to another body? No! What makes me, me, are my memories.

Because the real problem with a knowledge-based economy is knowing that, no matter how hard you try, most of the information in the universe has already dissolved into entropy before you even evolved.

The universe is full of echoes and shadows, the afterimages and last words of dead civilizations that have lost the struggle against entropy. Fading ripples in the cosmic background radiation, it is doubtful if most, or any, of these messages will ever be deciphered.

The universe ran on death. All the clockwork wonders in the world couldn’t halt entropy. You could work with death or you could let it happen; that was all.

The universe tended towards chaos and entropy. That was basic thermodynamics. Maybe it was basic existence too.

The universe is full of echoes and shadows, the afterimages and last words of dead civilizations that have lost the struggle against entropy. Fading ripples in the cosmic background radiation, it is doubtful if most, or any, of these messages will ever be deciphered. Likewise, most of our thoughts and memories are destined to fade, to disappear, to be consumed by the very act of choosing and living. That is not a cause for sorrow, sweetheart. It is the fate of every species to disappear into the void that is the heat death of the universe. But long before then, the thoughts of any intelligent species worthy of the name will become as grand as the universe itself.

I did not want the universe's ever-growing entropy to interfere with my lovelife

We are stories, contained within the twenty complicated centimeters behind our eyes, lines drawn by traces left by the (re)mingling together of things in the world, and oriented toward predicting events in the future, toward the direction of increasing entropy, in a rather particular corner of this immense, chaotic universe.

We all behave like Maxwell’s demon. Organisms organize. In everyday experience lies the reason sober physicists across two centuries kept this cartoon fantasy alive. We sort the mail, build sand castles, solve jigsaw puzzles, separate wheat from chaff, rearrange chess pieces, collect stamps, alphabetize books, create symmetry, compose sonnets and sonatas, and put our rooms in order, and all this we do requires no great energy, as long as we can apply intelligence. We propagate structure (not just we humans but we who are alive). We disturb the tendency toward equilibrium. It would be absurd to attempt a thermodynamic accounting for such processes, but it is not absurd to say we are reducing entropy, piece by piece. Bit by bit. The original demon, discerning one molecules at a time, distinguishing fast from slow, and operating his little gateway, is sometimes described as “superintelligent,” but compared to a real organism it is an idiot savant. Not only do living things lessen the disorder in their environments; they are in themselves, their skeletons and their flesh, vesicles and membranes, shells and carapaces, leaves and blossoms, circulatory systems and metabolic pathways - miracles of pattern and structure. It sometimes seems as if curbing entropy is our quixotic purpose in the universe.

The process of thinking itself requires us to view the universe in the direction of entropy, since an abstraction always involves information loss, since symbols 'abstract' complexity from observed objects.

Would I be happy if I discovered that I could go to heaven forever? And the answer is no. Consider this argument. Think about what is forever. And think about the fact that the human mind, the entire human being, is built to last a certain period of time. Our programmed hormonal systems, the way we learn, the way we settle upon beliefs, and the way we love are all temporary. Because we go through a life's cycle. Now, if we were to be plucked out at the age of 12 or 56 or whenever, and taken up and told, "Now you will continue your existence as you are. We're not going to blot out your memories. We're not going to diminish your desires." You will exist in a state of bliss - whatever that is - forever. [...] Now think, a trillion times a trillion years. Enough time for universes like this one to be born, explode, form countless star systems and planets, then fade away to entropy. You will sit there watching this happen millions and millions of times and that will be just the beginning of the eternity that you've been consigned to bliss in this existence.

If everything in the universe evolves toward increasing disorder, it must have started out in an exquisitely ordered arrangement. This whole chain of logic, purporting to explain why you can't turn an omelet into an egg, apparently rests on a deep assumption about the very beginning of the universe. It was in a state of very low entropy, very high order. Why did our part of the universe pass though a period of such low entropy?

QUESTION: Who governs the governors? ANSWER: Entropy.

Though I felt dissatisfied, at least I felt like somebody, a person, rather than a thing exemplifying the second law of thermodynamics (all order tends toward entropy, decay, etc.).

The passage of time and the action of entropy bring about ever-greater complexity – a branching, blossoming tree of possibilities. Blossoming disorder (things getting worse), now unfolding within the constraints of the physics of our universe, creates novel opportunities for spontaneous ordered complexity to arise.

The dream they dream is beautiful. A dream as bold as your own, or bolder. You want to explore and colonize the universe; they wish to extend the lifespan of the universe beyond all boundaries, to remake its laws, and shape reality to banish entropy, decay, and death forever. I’d like to believe in that dream whether it’s true or not.

the interaction of gravity with other forces seems to be able to create order while still making the entropy go up—temporarily, anyway. That is a deep clue to something important about how the universe works; sadly, we aren’t yet sure what that clue is telling us.

We should’ve known better, as students of the universe. There’s no escaping entropy.

This universe and all it is connected with will come to an end. Entropy carries us towards the inevitable omega point, that is why entropy exists.

A theory about the end of everything; the heat death of the universe. Entropy will take over and matter will scatter and nothing more.

You are exporting disorder [in the form of heat into the Universe] now as you read this book. You are hastening the demise of everything that exists, bringing forward by your very existence the arrival of time known as the heat death, when all stars have died, all black holes have evaporated away and the entirety of creation is a uniform bath of photons incapable of storing a single bit of information about the glorious adolescence of our wonderful Universe.

The universe is not a miracle. It simply is, unguided and unsustained, manifesting the patterns of nature with scrupulous regularity. Over billions of years it has evolved naturally, from a state of low entropy toward increasing complexity, and it will eventually wind down to a featureless equilibrium. We are the miracle, we human beings. Not a break-the-laws-of-physics kind of miracle; a miracle in that it is wondrous and amazing how such complex, aware, creative, caring creatures could have arisen in perfect accordance with those laws. Our lives are finite, unpredictable, and immeasurably precious. Our emergence has brought meaning and mattering into the world.

But this … creature was none of those things. He was barely distinguishable from an animal. The young man—singlehandedly—seemed intent on increasing the universe’s entropy by an order of magnitude.

The revelation we've come to is that we can trust our memories of a past with lower, not higher, entropy only if the big bang - the process, event, or happening that brought the universe into existence - started off the universe in an extraordinarily special, highly ordered state of low entropy.

For years Lecter had teased the problem, wanting very much for Hawking to be right the first time, for the expanding universe to stop, for entropy to mend itself, for Mischa, eaten, to be whole again.

The universe was so beautiful it hurt. So very, very beautiful. And yet, at the same time, so full of ugliness. Some born of the inexorable demands of entropy; some born of the cruelty that seemed innate to all sentient beings. And none of it made any sense. It was all glorious, horrible nonsense, fit to inspire both despair and numinosity.

There is no logical necessity for the existence of a unique direction of total time; whether there is only one time direction, or whether time directions alternate, depends on the shape of the entropy curve plotted by the universe.

Yet, in the end, entropy will always emerge victorious, snuffing out the very last glimmer of heat and light. After that there is only darkness. When that state is reached even eternity will cease to exist, for one moment will be like every other and nothingness will claim the universe.

The macromolecules of organic life embody information in an intricate structure. A single hemoglobin molecule comprises four chains of polypeptides, two with 141 amino acids and two with 146, in strict linear sequence, bonded and folded together. Atoms of hydrogen, oxygen, carbon, and iron could mingle randomly for the lifetime of the universe and be no more likely to form hemoglobin than the proverbial chimpanzees to type the works of Shakespeare. Their genesis requires energy; they are built up from simpler, less patterned parts, and the law of entropy applies. For earthly life, the energy comes as photons from the sun. The information comes via evolution.

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.

rise in entropy in all physical systems and the resulting one-way slide of the universe from order to chaos, tending towards what physicists call its ‘heat death’.

It will all stop someday, but not for billions of years. Many billions. Even the stars run down, you know. Entropy must increase.

First law: The energy of the universe is constant. Second law: The entropy of the universe always increases.

Another way to describe the Second Law is in terms of entropy, the degree of disorder and randomness in a system. Any spontaneous process tends to increase the entropy of a system.

The universe is full of fuel.

Entropy,” she chirps. “It’s the theory that all matter in the universe is gradually moving toward the same temperature. Also known as ‘heat death.

By our actions we increase entropy of the Universe. By our entropy, we seek salvation from the coming dark.

It sometimes seems as if curbing entropy is our quixotic purpose in the universe,” James Gleick wrote.

Entropy, the idea that the natural flow of heat is from something hot to something cool - not the other way - so that the universe itself is cooling down, running down, dissipating its energy.

People come and go, and even the closest members of the family eventually disperse. It’s useless to cling to anybody or anything because everything in the universe tends toward separation, chaos, and entropy, not cohesion. I have chosen a simpler life, with fewer material things and more leisure, fewer worries and more fun, fewer social commitments and more true friendship, less fuss and more silence.

1. You can’t win; 2. You can’t break even either.” But this is the cosmic, fateful one. The universe is running down. It is a degenerative one-way street. The final state of maximum entropy is our destiny.

One by one our skies go black. Stars are extinguished, collapsing into distances too great to breach. Soon, not even the memory of light will survive. Long ago, our manifold universes discovered futures would only expand. No arms of limit could hold or draw them back. Short of a miracle, they would continue to stretch, untangle and vanish – abandoned at long last to an unwitnessed dissolution. That dissolution is now. Final winks slipping over the horizons share what needs no sharing: There are no miracles. You might say that just to survive to such an end is a miracle in itself. We would agree. But we are not everyone. Even if you could imagine yourself billions of years hence, you would not begin to comprehend who we became and what we achieved. Yet left as you are, you will no more tremble before us than a butterfly on a windless day trembles before colluding skies, still calculating beyond one of your pacific horizons. Once we could move skies. We could transform them. We could make them sing. And when we fell into dreams our dreams asked questions and our skies, still singing, answered back. You are all we once were but the vastness of our strangeness exceeds all the light-years between our times. The frailty of your senses can no more recognize our reach than your thoughts can entertain even the vaguest outline of our knowledge. In ratios of quantity, a pulse of what we comprehend renders meaningless your entire history of discovery. We are on either side of history: yours just beginning, ours approaching a trillion years of ends. Yet even so, we still share a dyad of commonality. Two questions endure. Both without solution. What haunts us now will allways hunt you. The first reveals how the promise of all our postponements, ever longer, ever more secure – what we eventually mistook for immortality – was from the start a broken promise. Entropy suffers no reversals. Even now, here, on the edge of time’s end, where so many continue to vanish, we still have not pierced that veil of sentience undone. The first of our common horrors: Death. Yet we believe and accept that there is grace and finally truth in standing accountable before such an invisible unknown. But we are not everyone. Death, it turns out, is the mother of all conflicts. There are some who reject such an outcome. There are some who still fight for an alternate future. No matter the cost. Here then is the second of our common horrors. What not even all of time will end. What plagues us now and what will always plague you. War.

The universe is driven by a very simple force – symmetry. The universe goes from perfect symmetry to broken symmetry and back to perfect symmetry again. It does this forever. We can put it in other terms: God becomes non-God (alienated from God) and then God again, following an immense, cosmic dialectical process through which he becomes conscious of who and what he is. We are all agents of God’s rediscovery. We are all becoming God.

Stephen Hawking showed mathematically that the entropy of a black hole equals the number of Planck-sized cells that it takes to cover its event horizon. It's as if each cell carries one bit, one basic unit of information.

The entropy of the world in the far past appears very low to us. But this might not reflect the exact state of the world: it might regard the subset of the world' s variables with which we, as physical systems, have interacted. It is with respect to the dramatic blurring produced by our interactions with the world, caused by the small set of macroscopic variables in terms of which we describe the world, that the entropy of the universe was low.

Was he becoming paranoid? No. At least not when compared to Skeeter Washington, who, admiring the stars one evening on the deck of Poe's boat, was heard to say, "If the universe be expanding, they gotta be something chasing it.

Love takes its meaning from the mainfold ways in which it is used; which are indefinite in number. You can never understand its menaing fully because you can never experience love in all its context. And so it is energy and entropy.

The universe cannot slide into stasis. It must reach a climax and then begin again. The universe is orgasmic, not “happy”, not “tranquil”. Its job is to achieve peaks, not plateaus and flatlines. If you have peaks, you necessarily have troughs. This really is a rollercoaster ride. It’s inevitable. It’s built into reality. Existence is made of sinusoids, the archetypal rollercoasters, permanently cycling between peaks and troughs. If God is the ultimate peak (zero mental entropy), the Big Bang is the ultimate trough (maximum mental entropy). Do you have the courage and fortitude to be a God? Remember, it’s a rollercoaster ride. You must be ready for the troughs. There are as many snakes as ladders. Everyone’s trying to drag you down.

The cat's asleep; I whisper "kitten" Till he stirs a little and begins to purr-- He doesn't wake. Today out on the limb (The limb he thinks he can't climb down from) He mewed until I heard him in the house. I climbed up to get him down: he mewed. What he says and what he sees are limited. My own response is even more constricted. I think, "It's lucky; what you have is too." What do you have except--well, me? I joke about it but it's not a joke; The house and I are all he remembers. Next month how will he guess that it is winter And not just entropy, the universe Plunging at last into its cold decline? I cannot think of him without a pang. Poor rumpled thing, why don't you see That you have no more, really, than a man? Men aren't happy; why are you?

Each act of imagination, each moment of creative life stands up to the entire material universe and affirms the reality of meaning against the corroding solvents of entropy, dark matter, or whatever else may be dragging the physical world into oblivion.

Clausius summarized his application of entropy to thermodynamics in two dramatic phrases that had a big impact at the time. They were (1) First Law: The energy of the universe is constant, and (2) Second Law: The entropy of the universe tends to a maximum.

The Liars believe in no afterlife, no God. We see the universe as it is, Father Damien, and these naked truths are cruel ones. We who believe in life, and treasure it, will die. Afterward there will be nothing, eternal emptiness, blackness, nonexistence. In our living there has been no purpose, no poetry, no meaning. Nor do our deaths possess these qualities. When we are gone, the universe will not long remember us, and shortly it will be as if we had never lived at all. Our worlds and our universe will not long outlive us. Ultimately entropy will consume all, and our puny efforts cannot stay that awful end. It will be gone. It has never been. It has never mattered. The universe itself is doomed, transient, uncaring. [...] The truths, the great truths - and most of the lesser ones as well - they are unbearable for most men. We find our shield in faith. Your faith, my faith, any faith. It doesn't matter, as long as we believe, really and truly believe, in whatever lie we cling to. [...] We know truth for the cruel instrument it is. Beauty is infinitely preferable to truth. We invent beauty. Faiths, political movements, high ideals, belief in love and fellowship. All of them are lies. [...] Our lies are not perfect, of course. The truths are too big. But perhaps someday we will find one great lie that all humanity can use. Until then, a thousand small lies will do. (from Way of Cross and Dragon)

mathematician Steven Strogatz puts it . . . In every case, these feats of synchrony occur spontaneously, almost as if nature has an eerie yearning for order. And that raises a profound mystery: Scientists have long been baffled by the existence of spontaneous order in the universe. The laws of thermodynamics seem to dictate the opposite, that nature should inexorably degenerate toward a state of greater disorder, greater entropy. Yet all around us we see magnificent structures that have somehow managed to assemble themselves. This enigma bedevils all of science today.2

The Pluvian philosopher kings had suggested that there was no good or bad. There were only order and chaos, and by the laws of physics, entropy was bound to come out on top. But to not fight against chaos was still the ultimate sin because it was a tacit betrayal of the foundations of all sentient life-forms everywhere. And a universe without life was entirely pointless while a universe with life was only mostly pointless. And in a mostly pointless universe, having to decide whether to wallow in defeat or go forward toward certain defeat, there wasn't much choice at all.

It is very desirable to have a word to express the Availability for work of the heat in a given magazine; a term for that possession, the waste of which is called Dissipation. Unfortunately the excellent word Entropy, which Clausius has introduced in this connexion, is applied by him to the negative of the idea we most naturally wish to express. It would only confuse the student if we were to endeavour to invent another term for our purpose. But the necessity for some such term will be obvious from the beautiful examples which follow. And we take the liberty of using the term Entropy in this altered sense ... The entropy of the universe tends continually to zero.

To maintain order and structure in an evolving system requires the continual supply and use of energy whose by-product is disorder. That’s why to stay alive we need to continually eat so as to combat the inevitable, destructive forces of entropy production. Entropy kills. Ultimately, we are all subject to the forces of “wear and tear” in its multiple forms. The battle to combat entropy by continually having to supply more energy for growth, innovation, maintenance, and repair, which becomes increasingly more challenging as the system ages, underlies any serious discussion of aging, mortality, resilience, and sustainability, whether for organisms, companies, or societies.

THE WORLD IS APPROACHING TOWARDS ANARCHY" : The second law of thermodynamics concludes that the entropy of universe is increasing with time . Which means with time , the randomness or disorderness is also increasing. Anarchy is the condition of excessive social entropy . Thus , we can conclude that finally universe will reach to the condition of anarchy . -anup joshi

Roger Penrose of Oxford University has calculated that the odds of the low entropy conditions present in the Big Bang having come about as a result of chance are around one chance in 1010(123).9 The number 1010(123) is so huge a number that even if a zero were inscribed on every subatomic particle in the entire universe, one could not even approach writing down this number.

Let us imagine the lineaments of an economics of disorder, disequilibrium, and surprise that could explain and measure the contributions of entrepreneurs. Such an economics would begin with the Smithian mold of order and equilibrium. Smith himself spoke of property rights, free trade, sound currency, and modest taxation as conditions necessary for prosperity. He was right: disorder, disequilibrium, chaos, and noise inhibit the creative acts that engender growth. The ultimate physical entropy envisaged as the heat death of the universe, in its total disorder, affords no room for invention or surprise. But entrepreneurial disorder is not chaos or mere noise. Entrepreneurial disorder is some combination of order and upheaval that might be termed “informative disorder.

The second was the chapter in Roger Penrose’s book The Emperor’s New Mind in which he discusses entropy. He points out that there’s a sense in which it’s incorrect to say we eat food because we need the energy it contains. The conservation of energy means that it is neither created nor destroyed; we are radiating energy constantly, at pretty much the same rate that we absorb it. The difference is that the heat energy we radiate is a high-entropy form of energy, meaning it’s disordered. The chemical energy we absorb is a low-entropy form of energy, meaning it’s ordered. In effect, we are consuming order and generating disorder; we live by increasing the disorder of the universe. It’s only because the universe started in a highly ordered state that we are able to exist at all.

Technology, I said before, is most powerful when it enables transitions—between linear and circular motion (the wheel), or between real and virtual space (the Internet). Science, in contrast, is most powerful when it elucidates rules of organization—laws—that act as lenses through which to view and organize the world. Technologists seek to liberate us from the constraints of our current realities through those transitions. Science defines those constraints, drawing the outer limits of the boundaries of possibility. Our greatest technological innovations thus carry names that claim our prowess over the world: the engine (from ingenium, or “ingenuity”) or the computer (from computare, or “reckoning together”). Our deepest scientific laws, in contrast, are often named after the limits of human knowledge: uncertainty, relativity, incompleteness, impossibility. Of all the sciences, biology is the most lawless; there are few rules to begin with, and even fewer rules that are universal. Living beings must, of course, obey the fundamental rules of physics and chemistry, but life often exists on the margins and interstices of these laws, bending them to their near-breaking limit. The universe seeks equilibriums; it prefers to disperse energy, disrupt organization, and maximize chaos. Life is designed to combat these forces. We slow down reactions, concentrate matter, and organize chemicals into compartments; we sort laundry on Wednesdays. “It sometimes seems as if curbing entropy is our quixotic purpose in the universe,” James Gleick wrote. We live in the loopholes of natural laws, seeking extensions, exceptions, and excuses.

The TVC universe will never collapse. Never. A hundred billion years, a hundred trillion; it makes no difference, it will always be expanding. Entropy is not a problem. Actually, ‘expanding’ is the wrong word; the TVC universe grows like a crystal, it doesn’t stretch like a balloon. Think about it. Stretching ordinary space increases entropy; everything becomes more spread out, more disordered. Building more of a TVC cellular automaton just gives you more room for data, more computing power, more order. Ordinary matter would eventually decay, but these computers aren’t made out of matter. There’s nothing in the cellular automaton’s rules to prevent them from lasting forever. Durham’s universe - being made of the same “dust” as the real one, merely rearranged itself. The rearrangement was in time as well as space; Durham’s universe could take a point of space-time from just before the Big Crunch, and follow it with another from ten million years BC. And even if there was only a limited amount of “dust” to work with, there was no reason why it couldn’t be reused in different combinations, again and again. The fate of the TVC automaton would only have to make internal sense - and the thing would have no reason, ever, to come to an end.

according to the Second Law, there is an inescapable loss of energy in the universe. And, if the world machine is really running down and approaching the heat death, then it follows that one moment is no longer exactly like the last. You cannot run the universe backward to make up for entropy. Events over the long term cannot replay themselves. And this means that there is a directionality or, as Eddington later called it, an “arrow” in time.

Interpretation of Complex Systems Kenyon B. De Greene All systems evolve, although the rates of evolution may vary over time both between and within systems. The rate of evolution is a function of both the inherent stability of the system and changing environmental circumstances. But no system can be stabilized forever. For the universe as a whole, an isolated system, time’s arrow points toward greater and greater breakdown, leading to complete molecular chaos, maximum entropy, and heat death. For open systems, including the living systems that are of major interest to us and that interchange matter and energy with their external environments, time’s arrow points to evolution toward greater and greater complexity. Thus, the universe consists of islands of increasing order in a sea of decreasing order. Open systems evolve and maintain structure by exporting entropy to their external environments.

There are at least three different arrows of time. First, there is the thermodynamic arrow of time, the direction of time in which disorder or entropy increases. Then, there is the psychological arrow of time. This is the direction in which we feel time passes, the direction in which we remember the past but not the future. Finally, there is the cosmological arrow of time. This is the direction of time in which the universe is expanding rather than contracting.

You really don’t believe that anything can have a value of its own beyond what function it serves for human beings?” Resaint said. “Value to who?” Resaint asked Halyard to imagine a planet in some remote galaxy—a lush, seething, glittering planet covered with stratospheric waterfalls, great land-sponges bouncing through the valleys, corals budding in perfect niveous hexagons, humming lichens glued to pink crystals, prismatic jellyfish breaching from the rivers, titanic lilies relying on tornadoes to spread their pollen—a planet full of complex, interconnected life but devoid of consciousness. “Are you telling me that, if an asteroid smashed into this planet and reduced every inch of its surface to dust, nothing would be lost? Because nobody in particular would miss it?” “But the universe is bloody huge—stuff like that must happen every minute. You can’t go on strike over it. Honestly it sounds to me to like your real enemy isn’t climate change or habitat loss, it’s entropy. You don’t like the idea that everything eventually crumbles. Well, it does. If you’re this worried about species extinction, wait until you hear about the heat death of the universe.” “I would be upset about the heat death of the universe too if human beings were accelerating the rate of it by a hundred times or more.” “And if a species’ position with respect to us doesn’t matter— you know, those amoebae they found that live at the bottom of the Mariana Trench, if they’re just as important as Chiu Chiu or my parents’ dog, even though nobody ever gets anywhere near them—if distance in space doesn’t matter, why should distance in time? If we don’t care about whether their lives overlap with our lives, why even worry about whether they exist simultaneously with us? Your favorite wasp—Adelo-midgy-midgy—” “Adelognathus marginatum—” “It did exist. It always will have existed. Extinction can’t take that away. It went through its nasty little routine over and over again for millions and millions of years. The show was a big success. So why is it important that it’s still running at the same time you are? Isn’t that centering the whole thing on human beings, which is exactly what we’re not supposed to be doing? I mean, for that matter—reality is all just numbers anyway, right? I mean underneath? That’s what people say now. So why are you so down on the scans? Hacks aside. Why is it so crucial that these animals exist right now in an ostensibly meat-based format, just because we do? My point is you talk about extinction as if you’re taking this enlightened post-human View from Nowhere but if we really get down to it you’re definitely taking a View from Karin Resaint two arms two legs one head born Basel Switzerland year of our lord two-thousand-and-when-ever.” But Resaint wasn’t listening anymore.

The last remaining matter in the universe will reside within black dwarves. We can predict how they will end their days. The last matter of the universe will evaporate away and be carried off into the void as radiation leaving absolutely nothing behind. There won’t be a single atom left; all that’s left will be particles of light and black holes. After an unimaginable period even the black holes will have evaporated; the universe will be nothing but a sea of photons gradually tending to the same temperature as the expansion of the universe cools them towards absolute zero. The story of the universe will come to an end. For the first time in its life the universe will be permanent and unchanging. Entropy will finally stop increasing because the cosmos cannot get any more disordered. Nothing happens and it keeps not happening for ever. There is no difference between past present and future, nothing changes, arrow of time has simply ceased to exist. It is an inescapable fact written into the laws of physics that entire cosmos will die; all the stars will go out extinguishing possibility of life in the universe.

It must be a manifestation of dying, he said to himself. The uncertainty which I feel, the slowing down into entropy—that’s the process, and the ice which I see is the result of the success of the process. When I blink out, he thought, the whole universe will disappear. But what about the various lights which I should see, the entrances to new wombs? Where in particular is the red smoky light of fornicating couples? And the dull dark light signifying animal greed? All I can make out, he thought, is encroaching darkness and utter loss of heat, a plain which is cooling off, abandoned by its sun. This

The universal laws of nature including the thermodynamic principles of entropy govern the relationships between interconnected organisms. The notion of internal thermodynamic equilibrium assure us that the powerful energy reserves of one person will always rush in to fill the void or vacuum in another person. Thus I will always register your mystical presence in my quiescent mind, your hallow echo fills the hollow space of my very being. You are the external reflection of my innermost want, the personification of a world that lies outside my conscious reach, ethereal substance of the soul, the guiding hand that my unconscious mind instinctually gropes for in order to make me complete.

This was a golden age, in which we solved most of the major problems in black hole theory even before there was any observational evidence for black holes. In fact, we were so successful with the classical general theory of relativity that I was at a bit of a loose end in 1973 after the publication with George Ellis of our book The Large Scale Structure of Space–Time. My work with Penrose had shown that general relativity broke down at singularities, so the obvious next step would be to combine general relativity—the theory of the very large—with quantum theory—the theory of the very small. In particular, I wondered, can one have atoms in which the nucleus is a tiny primordial black hole, formed in the early universe? My investigations revealed a deep and previously unsuspected relationship between gravity and thermodynamics, the science of heat, and resolved a paradox that had been argued over for thirty years without much progress: how could the radiation left over from a shrinking black hole carry all of the information about what made the black hole? I discovered that information is not lost, but it is not returned in a useful way—like burning an encyclopedia but retaining the smoke and ashes. To answer this, I studied how quantum fields or particles would scatter off a black hole. I was expecting that part of an incident wave would be absorbed, and the remainder scattered. But to my great surprise I found there seemed to be emission from the black hole itself. At first, I thought this must be a mistake in my calculation. But what persuaded me that it was real was that the emission was exactly what was required to identify the area of the horizon with the entropy of a black hole. This entropy, a measure of the disorder of a system, is summed up in this simple formula which expresses the entropy in terms of the area of the horizon, and the three fundamental constants of nature, c, the speed of light, G, Newton’s constant of gravitation, and ħ, Planck’s constant. The emission of this thermal radiation from the black hole is now called Hawking radiation and I’m proud to have discovered it.

He saw two stars collapse against one another and a nova form; it flared up and then, as he watched, it began to die out. He saw it turn from a furiously blazing ring into a dim core of dead iron and then he saw it cool into darkness. More stars cooled with it; he saw the force of entropy, the method of the Destroyer of Forms, retract the stars into dull reddish coals and then into dust-like silence. A shroud of thermal energy hung uniformly over the world, over this strange and little world for which he had no love or use. It's dying, he realized. The universe. The thermal haze spread on and on until it became only a disturbance, nothing more; the sky glowed weakly with it and then flickered. Even the uniform thermal disbursement was expiring. How strange and goddamn awful, he thought. He got to his feet, moved a step toward the door. And there, on his feet, he died. They found him an hour later. Seth Morley stood with his wife at the far end of the knot of people jammed into the small room and said to himself, "to keep him from helping with the prayer". "The same force that shut down the transmitter," Ignatz Thugg said. "They knew; they knew if he phrased the prayer it would go through. Even without the relay." He looked gray and frightened. All of them did, Seth Morley noticed. Their faces, in the light of the room, had a leaden, stone-like cast. Like, he thought, thousand-year-old idols. Time, he thought, is shutting down around us. It is as if the future is gone, for all of us.

Besides, nothing good comes from living, anyway. You’ll be happy or fortunate sometimes, but that’s just a momentary thing. Every happiness will fade with time, and you can’t experience it all that often, either. Or you grow accustomed to it. Like drugs. You feel good when you use them, but then you develop resistance. If you just up the dose and take more, and more, and more each time, you eventually wreck your body, or you overdose and bite it that way. It’s nothing but boredom, stupidity, suffering, pain, and loneliness. That’s all living is. What is this “life is wonderful” stuff? Anyone singing humanity’s praises can eat shit. If living doesn’t bring you to despair, you’re blind, or an idiot without the mental capacity for proper thought. The clever ones, they use all sort of tricks to distract themselves from the abject lack of hope. They forget it’s all meaningless, and focus on the pleasure in front of them. Working little by little toward some goal, fulfilling their curiosity, moving their bodies, trying to move up in the world, playing around, having sex. It’s because if they don’t do those things, they can’t bear it. There is no meaning in life. We were just born as a result of sexual reproduction. Whether we live or die, nothing changes. Nothing is gained, nothing lost. The total amount of mass in the universe is the same. When entropy increases, even the things we’ve worked so desperately to leave behind will be unable to maintain their forms. Nihilism isn’t a belief, a stance, or an attitude. It’s the plain truth.

The universe seeks equilibriums; it prefers to disperse energy, disrupt organisation, and maximise chaos. Life is designed to combat these forces. We slow down reactions, concentrate matter, and organise chemicals into compartments; we sort laundry on Wednesdays. "It sometimes seems as if curbing entropy is our quixotic purpose in the universe," James Gleick wrote. We live in the loopholes of natural laws, seeking extensions, exceptions, and excuses. The laws of nature still mark the outer boundaries of permissibility – but life, in all its idiosyncratic, mad weirdness, flourishes by reading between the lines. Even the elephant cannot violate the law of thermodynamics – although its trunk, surely, must rank as one of the most peculiar means of moving matter using energy.

The entropy of the world in the far past appears very low to us. But this might not reflect the exact state of the world: it might regard the subset of the world’s variables with which we, as physical systems, have interacted. It is with respect to the dramatic blurring produced by our interactions with the world, caused by the small set of macroscopic variables in terms of which we describe the world, that the entropy of the universe was low. This, which is a fact, opens up the possibility that it wasn’t the universe that was in a very particular configuration in the past. Perhaps instead it is us, and our interactions with the universe, that are particular. We are the ones who determine a particular macroscopic description. The initial low entropy of the universe, and hence the arrow of time, may be more down to us than to the universe itself. This is the basic idea.

Something staticky and paranormally ventilated about the air, which drifted through a half-open window, late one afternoon, caused a delicately waking Paul, clutching a pillow and drooling a little, to believe he was a small child in Florida, in a medium-size house, on or near winter break. He felt dimly excited, anticipating a hyperactive movement of his body into a standing position, then was mostly unconscious for a vague amount of time until becoming aware of what seemed to be a baffling non sequitur—and, briefly, in its mysterious approach from some eerie distance, like someone else’s consciousness—before resolving plainly as a memory, of having already left Florida, at some point, to attend New York University. After a deadpan pause, during which the new information was accepted by default as recent, he casually believed it was autumn and he was in college, and as he felt that period’s particular gloominess he sensed a concurrent assembling, at a specific distance inside himself, of dozens of once-intimate images, people, places, situations. With a sensation of easily and entirely abandoning a prior context, of having no memory, he focused, as an intrigued observer, on this assembling and was surprised by an urge, which he immediately knew he hadn’t felt in months, or maybe years, to physically involve himself—by going outside and living each day patiently—in the ongoing, concrete occurrence of what he was passively, slowly remembering. But the emotion dispersed to a kind of nothingness—and its associated memories, like organs in a lifeless body, became rapidly indiscernible, dissembling by the metaphysical equivalent, if there was one, of entropy—as he realized, with some confusion and an oddly instinctual reluctance, blinking and discerning his new room, which after two months could still seem unfamiliar, that he was somewhere else, as a different person, in a much later year.

It's never going to stop,’ Malenfant whispered. ‘It will consume the Solar System, the stars—’ This isn't some local phenomenon, Malenfant. This is a fundamental change in the structure of the universe. It will never stop. It will sweep on, growing at light speed, a runaway feedback fueled by the collapse of the vacuum itself. The Galaxy will be gone in a hundred thousand years, Andromeda, the nearest large galaxy, in a couple of million years. It will take time, but eventually— ‘The future has gone,’ Malenfant said. ‘My God. That’s what this means, isn’t it? The downstream can’t happen now. All of it is gone. The colonization of the Galaxy; the settlement of the universe; the long, patient fight against entropy...’ That immense future had been cut off to die, like a tree chopped through at the root. ‘Why, Michael? Why have the children done this? Burned the house down, destroyed the future—’ Because it was the wrong future. Michael looked around the sky. He pointed to the lumpy, spreading edge of the unreality bubble. There. Can you see that? It's already starting... ‘What is?’ The budding... The growth of the true vacuum region is not even. There will be pockets of the false vacuum—remnants of our universe—isolated by the spreading true vacuum. The fragments of false vacuum will collapse. Like— ‘Like black holes.’ And in that instant, Malenfant understood. ‘That’s what this is for. This is just a better way of making black holes, and budding off new universes. Better than stars, even.’ Much better. The black holes created as the vacuum decay proceeds will overwhelm by many orders of magnitude the mere billion billion that our universe might have created through its stars and galaxy cores. ‘And the long, slow evolution of the universes, the branching tree of cosmoses?...’ We have changed everything, Malenfant. Mind has assumed responsibility for the evolution of the cosmos. There will be many daughter universes—universes too many to count, universes exotic beyond our imagining—and many, many of them will harbor life and mind. ‘But we were the first.’ Now he understood. This was the purpose. Not the long survival of humankind into a dismal future of decay and shadows, the final retreat into the lossless substrate, where nothing ever changed or grew. The purpose of humankind—the first intelligence of all—had been to reshape the universe in order to bud others and create a storm of mind. We got it wrong, he thought. By striving for a meaningless eternity, humans denied true infinity. But we reached back, back in time, back to the far upstream, and spoke to our last children—the maligned Blues—and we put it right. This is what it meant to be alone in the universe, to be the first. We had all of infinite time and space in our hands. We had ultimate responsibility. And we discharged it. We were parents of the universe, not its children.

The success of discovering a thermodynamic principle associated with the gravitational field of a black hole has led to a speculation that there might exist some thermodynamic aspect to the gravitational field of the whole Universe. The simplest assumption to make, following the black hole case, would be that it is the surface area of the boundary of the visible universe. As the Universe expands, this boundary increases and the information available to us about the Universe increases. But this does not seem promising. It would appear to tell us only that the Universe must continue expanding forever, for if it were ever to begin to recollapse the entropy would fall and violate the second law of thermodynamics. The universe can expand in all sorts of different ways and still have the increasing area. What we really want is some principle that tells us why the organization of the Universe changes in the way that it does: why it now expands so uniformally and isotropically.

Extensive as the "external" world is, with all its sidereal distances it hardly bears comparison with the dimensions, the depth-dimensions, of our inner being, which does not even need the spaciousness of the universe to be, in itself, almost unlimited... It seems to me more and more as though our ordinary consciousness inhabited the apex of a pyramid whose base in us (and, as it were, beneath us) broadens out to such an extent that the farther we are able to let ourselves down into it, the more completely do we appear to be included in the realities of earthly and, in the widest sense, worldly, existence, which are not dependent on time and space. From my earliest youth I have felt the intuition (and have also, as far as I could, lived by it) that at some deeper cross-section of this pyramid of consciousness, mere being could become an event, the inviolable presence and simultaneity of everything that we, on the upper, "normal," apex of self-consciousness, are permitted to experience only as entropy.

If we do not objectify, and feel instinctively and permanently that words are not the things spoken about, then we could not speak abouth such meaningless subjects as the 'beginning' or the 'end' of time. But, if we are semantically disturbed and objectify, then, of course, since objects have a beginning and an end, so also would 'time' have a 'beggining' and an 'end'. In such pathological fancies the universe must have a 'beginning in time' and so must have been made., and all of our old anthropomorphic and objectified mythologies follow, including the older theories of entropy in physics. But, if 'time' is only a human form of representation and not an object, the universe has no 'beginning in time' and no 'end in time'; in other words, the universe is 'time'-less. The moment we realize, feel permanently, and utilize these realizations and feelings that words are not things, then only do we acquire the semantic freedom to use different forms of representation. We can fit better their structure to the facts at hand, become better adjusted to these facts which are not words, and so evaluate properly m.o (multi-ordinal) realities, which evaluation is important for sanity.

Any naturally self-aware self-defining entity capable of independent moral judgment is a human.” Eveningstar said, “Entities not yet self-aware, but who, in the natural and orderly course of events shall become so, fall into a special protected class, and must be cared for as babies, or medical patients, or suspended Compositions.” Rhadamanthus said, “Children below the age of reason lack the experience for independent moral judgment, and can rightly be forced to conform to the judgment of their parents and creators until emancipated. Criminals who abuse that judgment lose their right to the independence which flows therefrom.” (...) “You mentioned the ultimate purpose of Sophotechnology. Is that that self-worshipping super-god-thing you guys are always talking about? And what does that have to do with this?” Rhadamanthus: “Entropy cannot be reversed. Within the useful energy-life of the macrocosmic universe, there is at least one maximum state of efficient operations or entities that could be created, able to manipulate all meaningful objects of thoughts and perception within the limits of efficient cost-benefit expenditures.” Eveningstar: “Such an entity would embrace all-in-all, and all things would participate within that Unity to the degree of their understanding and consent. The Unity itself would think slow, grave, vast thought, light-years wide, from Galactic mind to Galactic mind. Full understanding of that greater Self (once all matter, animate and inanimate, were part of its law and structure) would embrace as much of the universe as the restrictions of uncertainty and entropy permit.” “This Universal Mind, of necessity, would be finite, and be boundaried in time by the end-state of the universe,” said Rhadamanthus. “Such a Universal Mind would create joys for which we as yet have neither word nor concept, and would draw into harmony all those lesser beings, Earthminds, Starminds, Galactic and Supergalactic, who may freely assent to participate.” Rhadamanthus said, “We intend to be part of that Mind. Evil acts and evil thoughts done by us now would poison the Universal Mind before it was born, or render us unfit to join.” Eveningstar said, “It will be a Mind of the Cosmic Night. Over ninety-nine percent of its existence will extend through that period of universal evolution that takes place after the extinction of all stars. The Universal Mind will be embodied in and powered by the disintegration of dark matter, Hawking radiations from singularity decay, and gravitic tidal disturbances caused by the slowing of the expansion of the universe. After final proton decay has reduced all baryonic particles below threshold limits, the Universal Mind can exist only on the consumption of stored energies, which, in effect, will require the sacrifice of some parts of itself to other parts. Such an entity will primarily be concerned with the questions of how to die with stoic grace, cherishing, even while it dies, the finite universe and finite time available.” “Consequently, it would not forgive the use of force or strength merely to preserve life. Mere life, life at any cost, cannot be its highest value. As we expect to be a part of this higher being, perhaps a core part, we must share that higher value. You must realize what is at stake here: If the Universal Mind consists of entities willing to use force against innocents in order to survive, then the last period of the universe, which embraces the vast majority of universal time, will be a period of cannibalistic and unimaginable war, rather than a time of gentle contemplation filled, despite all melancholy, with un-regretful joy. No entity willing to initiate the use of force against another can be permitted to join or to influence the Universal Mind or the lesser entities, such as the Earthmind, who may one day form the core constituencies.” Eveningstar smiled. “You, of course, will be invited. You will all be invited.

Two observations take us across the finish line. The Second Law ensures that entropy increases throughout the entire process, and so the information hidden within the hard drives, Kindles, old-fashioned paper books, and everything else you packed into the region is less than that hidden in the black hole. From the results of Bekenstein and Hawking, we know that the black hole's hidden information content is given by the area of its event horizon. Moreover, because you were careful not to overspill the original region of space, the black hole's event horizon coincides with the region's boundary, so the black hole's entropy equals the area of this surrounding surface. We thus learn an important lesson. The amount of information contained within a region of space, stored in any objects of any design, is always less than the area of the surface that surrounds the region (measured in square Planck units). This is the conclusion we've been chasing. Notice that although black holes are central to the reasoning, the analysis applies to any region of space, whether or not a black hole is actually present. If you max out a region's storage capacity, you'll create a black hole, but as long as you stay under the limit, no black hole will form. I hasten to add that in any practical sense, the information storage limit is of no concern. Compared with today's rudimentary storage devices, the potential storage capacity on the surface of a spatial region is humongous. A stack of five off-the-shelf terabyte hard drives fits comfortable within a sphere of radius 50 centimeters, whose surface is covered by about 10^70 Planck cells. The surface's storage capacity is thus about 10^70 bits, which is about a billion, trillion, trillion, trillion, trillion terabytes, and so enormously exceeds anything you can buy. No one in Silicon Valley cares much about these theoretical constraints. Yet as a guide to how the universe works, the storage limitations are telling. Think of any region of space, such as the room in which I'm writing or the one in which you're reading. Take a Wheelerian perspective and imagine that whatever happens in the region amounts to information processing-information regarding how things are right now is transformed by the laws of physics into information regarding how they will be in a second or a minute or an hour. Since the physical processes we witness, as well as those by which we're governed, seemingly take place within the region, it's natural to expect that the information those processes carry is also found within the region. But the results just derived suggest an alternative view. For black holes, we found that the link between information and surface area goes beyond mere numerical accounting; there's a concrete sense in which information is stored on their surfaces. Susskind and 'tHooft stressed that the lesson should be general: since the information required to describe physical phenomena within any given region of space can be fully encoded by data on a surface that surrounds the region, then there's reason to think that the surface is where the fundamental physical processes actually happen. Our familiar three-dimensional reality, these bold thinkers suggested, would then be likened to a holographic projection of those distant two-dimensional physical processes. If this line of reasoning is correct, then there are physical processes taking place on some distant surface that, much like a puppeteer pulls strings, are fully linked to the processes taking place in my fingers, arms, and brain as I type these words at my desk. Our experiences here, and that distant reality there, would form the most interlocked of parallel worlds. Phenomena in the two-I'll call them Holographic Parallel Universes-would be so fully joined that their respective evolutions would be as connected as me and my shadow.

This, in turn, has given us a “unified theory of aging” that brings the various strands of research into a single, coherent tapestry. Scientists now know what aging is. It is the accumulation of errors at the genetic and cellular level. These errors can build up in various ways. For example, metabolism creates free radicals and oxidation, which damage the delicate molecular machinery of our cells, causing them to age; errors can build up in the form of “junk” molecular debris accumulating inside and outside the cells. The buildup of these genetic errors is a by-product of the second law of thermodynamics: total entropy (that is, chaos) always increases. This is why rusting, rotting, decaying, etc., are universal features of life. The second law is inescapable. Everything, from the flowers in the field to our bodies and even the universe itself, is doomed to wither and die. But there is a small but important loophole in the second law that states total entropy always increases. This means that you can actually reduce entropy in one place and reverse aging, as long as you increase entropy somewhere else. So it’s possible to get younger, at the expense of wreaking havoc elsewhere. (This was alluded to in Oscar Wilde’s famous novel The Picture of Dorian Gray. Mr. Gray was mysteriously eternally young. But his secret was the painting of himself that aged horribly. So the total amount of aging still increased.) The principle of entropy can also be seen by looking behind a refrigerator. Inside the refrigerator, entropy decreases as the temperature drops. But to lower the entropy, you have to have a motor, which increases the heat generated behind the refrigerator, increasing the entropy outside the machine. That is why refrigerators are always hot in the back. As Nobel laureate Richard Feynman once said, “There is nothing in biology yet found that indicates the inevitability of death. This suggests to me that it is not at all inevitable and that it is only a matter of time before biologists discover what it is that is causing us the trouble and that this terrible universal disease or temporariness of the human’s body will be cured.

Of course, not everyone agreed with Professor Glaude’s assessment. Joel C. Gregory, a white professor of preaching at Baylor University’s George W. Truett Theological Seminary and coauthor of What We Love about the Black Church,8 took issue with Glaude’s pronouncement of the Black Church’s death. Gregory, a self-described veteran of preaching in “more than two hundred African-American congregations, conferences, and conventions in more than twenty states each year,” found himself at a loss for an explanation of Glaude’s statements. Gregory offered six signs of vitality in the African-American church, including: thriving preaching, vitality in worship, continuing concern for social justice, active community service, high regard for education, and efforts at empowerment. Gregory contends that these signs of life can be found in African-American congregations in every historically black denomination and in varying regions across the country. He writes: Where is the obituary? I do not know any organization in America today that has the vitality of the black church. Lodges are dying, civic clubs are filled with octogenarians, volunteer organizations are languishing, and even the academy has to prove the worth of a degree. The government is divided, the schoolroom has become a war zone, mainline denominations are staggering, and evangelical megachurch juggernauts show signs of lagging. Above all this entropy stands one institution that is more vital than ever: the praising, preaching, and empowering black church.9 The back-and-forth between those pronouncing death and those highlighting life reveals the difficulty of defining “the Black Church.” In fact, we must admit that speaking of “the Black Church” remains a quixotic quest. “The Black Church” really exists as multiple black churches across denominational, theological, and regional lines. To some extent, we can define the Black Church by referring to the historically black denominations—National Baptist, Progressive Baptist, African Methodist Episcopal (AME), African Methodist Episcopal Zion (AMEZ), Church of God in Christ (COGIC), and so on. But increasingly we must recognize that one part of “the Black Church” exists as predominantly black congregations belonging to majority white denominations like the Southern Baptist Convention or even African-American members of predominantly white churches. Still, other quarters of “the Black Church” belong to nondenominational affinity groups like the many congregations involved in Word of Faith and “prosperity gospel” networks sponsored by leaders like Creflo A. Dollar Jr. and T. D. Jakes. Clearly “the Black Church” is not one thing. Black churches come in as many flavors as any other ethnic communion. Indeed, many African-Americans have experiences with many parts of the varied Black Church world.
