Spaced Brian Quotes

I was waiting for the longest time, she said. I thought you forgot. It is hard to forget, I said, when there is such an empty space when you are gone.

Quiet Spaces We had gone far enough together to listen easily in the quiet spaces.

Cosmology is among the oldest subjects to captivate our species. And it’s no wonder. We’re storytellers, and what could be more grand than the story of creation?

Understanding requires insight. Insight must be anchored.

Physicists have come to realize that mathematics, when used with sufficient care, is a proven pathway to truth.

I feel that what you should illustrate is the space between the words. It's the betweenness, the otherness, that gives depth and dimension.

Science fiction is for real, space opera is for fun.

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.

Empty Spaces: After his father died he carried his life more gently & left an empty space for the birds & other creatures.

But, as Einstein once said, “For we convinced physicists, the distinction between past, present, and future is only an illusion, however persistent.”5

some of the biggest challenges faced by computers and human minds alike: how to manage finite space, finite time, limited attention, unknown unknowns, incomplete information, and an unforeseeable future; how to do so with grace and confidence; and how to do so in a community with others who are all simultaneously trying to do the same.

Why is your species so dissatisfied?” “How so?” “Humans are individuals, quite social in nature. You strive to become more than yourselves using Silicon reconstructions in your bodies and filaments in your brains connecting you, unnaturally, to the NET.” “Our bodies are mortal. We employ silicon and alloys to extend our bodies’ existence.” “You appear to be attempting the same strategy with your brains’ architectures.” “By using the NET? Is that what you mean?” “You will never accomplish this. You must know it.” “Surely you can understand that as we are now, we have what we consider a limited lifespan, and, it seems, so does this planet. When the inevitable happens, we will not be able to travel any substantial distance in space. We cannot escape our dying planet. Humanity will cease to exist if we fail. We face our ultimate existential crisis as a species. Our most basic instinct is the survival of our species, so you see we must try. It is in our nature. It is evolution or elimination.

If there is a lot of matter, gravity will cause space to curve back on itself, yielding the spherical shape. If there is little matter, space is free to flare outward in the Pringles shape. And if there is just the right amount of matter, space will have zero curvature.*

No choice recurs. We may get similar choices again, but never that exact one. Hesitation—inaction—is just as irrevocable as action. What the motorist, locked on the one-way road, is to space, we are to the fourth dimension: we truly pass this way but once.

The world of the everyday suddenly seemed nothing but an inverted magic act, lulling its audience into believing in the usual, familiar conceptions of space and time, while the astonishing truth of quantum reality lay carefully guarded by nature's sleights of hand.

For your business to stand out and succeed, you have to put a primary focus on the social media space, go in big (halfway will not do), and do it better than most, right from the start.

The greatest relevancy can become irrelevant in the space of a heartbeat.

She did not want conversation or company, just the presence of other people; she hoped the background drone of their lives would fill the empty spaces in her mind.

Far from being accidental details, the properties of nature's basic building blocks are deeply entwined with the fabric of space and time.

He is only one of a million no, a billion stories you could tell about the living beings on just this side of the mountain. The fact is that there are more stories in the space of a single second, in a single square foot of dirt and air and water, then we could tell in a hundred years. The word amazing isn't much of a word for how amazing it is. The fact is that there are more stories in the world than there are fish in the sea or birds in the air or lies among politicians. You could be sad at how many stories go untold, but you could also be delighted at how many stories we catch and share in delight and wonder and astonishment and illumination and sometimes even epiphany.

So: if you buy the notion that reality consists of the things in your freeze-frame mental image right now, and if you agree that your now is no more valid than the now of someone located far away in space who can move freely, then reality encompasses all of the events in spacetime.

Ben had never seen his mother cry before, and it startled him, so he didn't ask again. Right afterward she'd put on her favorite record and played a mysterious song called "Space Oddity," about an astronaut named Major Tom who gets lost in space. She used to listen to the song over and over again. With her eyes closed, she'd place the palm of her hand against the fabric of the speaker, so she could feel it vibrate against her skin.

Ciba: "I thought you were supposed to be some big brave war hero. What about that goddamn gold star you polish every night?" Natalya: "You know what this shiny piece of tin is, you fucking space cadet? It's the way stupid boys trick other stupid boys into dying for bullshit causes ... and I'm done acting like one of them.

Anytime that is ‘betwixt and between’ or transitional is the faeries’ favorite time. They inhabit transitional spaces: the bottom of the garden, existing in a space between manmade cultivation and wilderness. Look for them in the space between nurture and nature, they are to be found at all boarders and boundaries, or on the edges of water where it is neither land nor lake, neither path nor pond. They come when we are half-asleep. They come at moments when we least expect them; when our rational mind balances with the fluid irrational.

If you travel in space for three years and come back, four hundred years will have passed on Earth. I am only an armchair astronomer, but I have the odd sense that I have returned from a journey to a world where nothing quite makes sense.

Just as we envision all of space as really being out there, as really existing, we should also envision all of time as really being out there, as really existing too.

She was very small, and her eyes were pale blue and watery. She cried a lot. She was possibly the bravest person Brian knew.

Like a picture out of focus, I’m starting to think that I don’t even know who I am anymore. And that feeling – like being sucked out into the vacuum of space without a suit – is the most terrifying of all.

Two and a half million years ago, when our distant relative Homo habilis was foraging for food across the Tanzanian savannah, a beam of light left the Andromeda Galaxy and began its journey across the Universe. As that light beam raced across space at the speed of light, generations of pre-humans and humans lived and died; whole species evolved and became extinct, until one member of that unbroken lineage, me, happened to gaze up into the sky below the constellation we call Cassiopeia and focus that beam of light onto his retina. A two-and-a-half-billion-year journey ends by creating an electrical impulse in a nerve fibre, triggering a cascade of wonder in a complex organ called the human brain that didn’t exist anywhere in the Universe when the journey began.

Jesus is not so much telling us to mourn as he is making an announcement to those who do mourn. Sorrow is a necessary consequence of loving others and being fully engaged with humanity. If our plan is to go through life minimizing pain and avoiding as much sorrow as possible, we will do so as a shallow people, and Jesus has nothing to announce to us in the second beatitude—he simply leaves us in our prosaic self-contentment. It is through the work of grief that we carve depth into our souls and create space to be filled with comfort from another.

There is but one truly philosophical problem, and that is suicide,” the text began. I winced. “Whether or not the world has three dimensions or the mind nine or twelve categories,” it continued, “comes afterward”; such questions, the text explained, were part of the game humanity played, but they deserved attention only after the one true issue had been settled. The book was The Myth of Sisyphus and was written by the Algerian-born philosopher and Nobel laureate Albert Camus. After a moment, the iciness of his words melted under the light of comprehension. Yes, of course, I thought. You can ponder this or analyze that till the cows come home, but the real question is whether all your ponderings and analyses will convince you that life is worth living. That’s what it all comes down to. Everything else is detail.

High schools are, ultimately, a messy stew of hearts and hormones all swirling around together in the smallest possible space. Don't feel bad about not having gotten out of there with your dignity intact, because nobody did. Even dreamy Jordan Catalano will always have to live with the embarrassment of having mistakenly addressed Brian as 'Brain.

If you were to head out into the cosmos, traveling ever farther, would you find that space goes on indefinitely, or that it abruptly ends?

Brian belatedly realized that if you told a lot of lies, even if it was for a good reason, like trying to keep people safe, it started to get hard to trust that other people were telling the truth.

One of the reasons I took this trip is to prove to myself that I am allowed to take up space in the world. I used to believe that the space I occupied was conditional. That I had to please anyone and everyone around me in order to exist because I had made the horrible mistake of being different.

Much as Hamlet famously declares, “I could be bounded in a nutshell, and count myself a king of infinite space,” each of the bubble universes appears to have finite spatial extent when examined from the outside, but infinite spatial extent when examined from the inside. And that’s a marvelous realization

A bubble between dimensions. A wormhole to a space without time, where something vast sat and waited, in a lair where a billion years felt no different than a day. Maybe it had crawled there eons ago. Maybe the planet had amalgamated around it.

It was out of the dynamic of cosmic celebration that we were created in the first place. We are to become celebration and generosity, burst into self-awareness. What is the human? The human is a space, an opening, where the universe celebrates its existence.

And since, according to the big bang theory, the bang is what is supposed to have happened at the beginning, the big bang leaves out the bang. It tells us nothing about what banged, why it banged, how it banged, or, frankly, whether it ever really banged at all.

Quantum mechanics challenges this view by revealing, at least in certain circumstances, a capacity to transcend space; long-range quantum connections can bypass spatial separation. Two objects can be far apart in space, but as far as quantum mechanics is concerned, it’s as if they’re a single entity.

So very many silences, and kinds of silence: chapels and churches and confessionals, glades and gorges, pregnant pauses and searing lovemaking; the stifling stifled brooding silence just before a thunderstorm unleashes itself wild on the world; the silence of space, the vast of vista; the crucial silences between notes, without which there could be no music;

Well, the good news is I killed the space monster.

I should imagine that space-time as we now know it will hold no meaning for me at that stage of evolution. I'll be a chick magnet.

We are beyond life and death, beyond space and beyond time. We are the gods, and they are us.

If you can't open up your heart to create a space for healing and forgiveness, there will be no room to create a space, for a new lover.

A mecânica quântica é implacavelmente eficiente; explica aquilo que vemos, mas impede-vos de ver a explicação.

Fused in stars and ejected in supernova explosions, or jettisoned by stellar collisions and amalgamated in particle plumes, an assortment of atomic species float through space, where they swirl together and coalesce into large clouds of gas, which over yet more time clump anew into stars and planets, and ultimately into us. Such is the origin of the ingredients constituting anything and everything you have ever encountered.

She'd already accepted that she loved him, hadn't she? And it had been easy, a simple process of steps and study. Her mind was amde up, her goals set. Damn it, she'd been pleased by the whole business. So what was this shaky, dizzy, painful sensation, this clutch of panic that made her want to turn her mount sharply around and ride as far away as possible? She'd been wrong, Keeyley realized as she pressed an unsteady hand to her jumpy heart.She'd only been falling in love up to now.How foolish of her to be lulled by the smooth slide of it.This was the moment, she understood that now. This was the moment the bottom dropped away and sent her crashing. Now the wind was knocked out of her, that same shock of sensation that came from losing your seat over a jump and findng yourself flipping through space until the ground reached up and smacked into you. Jolting bones and head and heart. Love was an outrageous shock to the system, she thought. It was a wonder anyone survived it. She was a Grant, Keeley reminded herself and straightened in the saddle. She knew how to take a tumble, jsut as she knew how to pick herself back up and focus mind and energy on the goal. She wouldn't just survive this knock to the heart.She'd thrive on it.And when she was done with Brian Donnelly, he wouldn't know what had hit him.

PREFACE A New Look at the Legacy of Albert Einstein Genius. Absent-minded professor. The father of relativity. The mythical figure of Albert Einstein—hair flaming in the wind, sockless, wearing an oversized sweatshirt, puffing on his pipe, oblivious to his surroundings—is etched indelibly on our minds. “A pop icon on a par with Elvis Presley and Marilyn Monroe, he stares enigmatically from postcards, magazine covers, T-shirts, and larger-than-life posters. A Beverly Hills agent markets his image for television commercials. He would have hated it all,” writes biographer Denis Brian. Einstein is among the greatest scientists of all time, a towering figure who ranks alongside Isaac Newton for his contributions. Not surprisingly, Time magazine voted him the Person of the Century. Many historians have placed him among the hundred most influential people of the last thousand years.

They imply that a region of space the size of a pea would be stretched larger than the observable universe in a time interval so short that the blink of an eye would overestimate it by a factor larger than a million billion billion billion.

The next pages begin our journey through some of the biggest challenges faced by computers and human minds alike: how to manage finite space, finite time, limited attention, unknown unknowns, incomplete information, and an unforeseeable future;

A full explanation of this is beyond the scope of this book, suffice to say that Einstein was forced into this bold move primarily because Maxwell’s equations for electricity and magnetism were incompatible with Newton’s 200-year-old laws of motion. Einstein abandoned the Newtonian ideas of space and time as separate entities and merged them. In Einstein’s theory there is a special speed built into the structure of spacetime itself that everyone must agree on, irrespective of how they are moving relative to each other. This special speed is a universal constant of nature that will always be measured as precisely 299,792,458 metres (983,571,503 feet) per second, at all times and all places in the Universe, no matter what they are doing. This

We do need to create a space for the J.D.s and Brians of the world to have a chance. I don’t know what the answer is, precisely, but I know it starts when we stop blaming Obama or Bush or faceless companies and ask ourselves what we can do to make things better. I

We know this because finding an apartment belongs to a class of mathematical problems known as “optimal stopping” problems. The 37% rule defines a simple series of steps—what computer scientists call an “algorithm”—for solving these problems. And as it turns out, apartment hunting is just one of the ways that optimal stopping rears its head in daily life. Committing to or forgoing a succession of options is a structure that appears in life again and again, in slightly different incarnations. How many times to circle the block before pulling into a parking space? How far to push your luck with a risky business venture before cashing out? How long to hold out for a better offer on that house or car? The same challenge also appears in an even more fraught setting: dating. Optimal stopping is the science of serial monogamy.

The Air Force was confused about what it wanted me to be when I grew up. I applied for an ROTC scholarship out of high school because I wanted to be an astronaut. None of my teachers had ever broken the news to me that I couldn’t fly into space, so the third-grade dream remained.

Later, we shall see that if it were possible to exceed the speed of light, we could construct time machines capable of transporting us backward through history to any point in the past. We could imagine journeying back to a time before we were born and, by accident or design, preventing our parents from ever meeting. This makes for excellent science fiction, but it is no way to build a universe, and indeed Einstein found that the universe is not built like this. Space and time are delicately interwoven in a way that prevents such paradoxes from occurring.

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.

Famously, Einstein said that his ‘happiest thought’ occurred here: ‘I was sitting in a chair in the Patent Office at Bern when all of a sudden a thought occurred to me. If a person falls freely he will not feel his own weight. I was startled.’ By thinking of someone falling, for example in a plummeting lift, Einstein had realised that it was impossible to distinguish acceleration and the pull of gravity. And working through the mathematical implications of this made it clear that gravity was an effect that could be produced by a distortion of space and time.

Bruno believed that the universe is infinite and filled with an infinite number of habitable worlds. He also believed that although each world exists for a brief moment when compared to the life of the universe, space itself is neither created nor destroyed; the universe is eternal.

According to special relativity, no longer can space and time be thought of as universal concepts set in stone, experienced identically by everyone. Rather, space and time emerged from Einstein's reworking as malleable constructs whose form and appearance depend on one's state of motion.

The ideal parking space, as Shoup models it, is one that optimizes a precise balance between the “sticker price” of the space, the time and inconvenience of walking, the time taken seeking the space (which varies wildly with destination, time of day, etc.), and the gas burned in doing so.

The extreme disparity between the outsider's and insider's perspectives arises because they have vastly different conceptions of time. Although the point is far from obvious, we'll now see what appears as endless time to an outsider appears as endless space, at each moment of time, to an insider.

As far as Stephen could see they were tolerably shipshape already. The bare little rooms had been sanded and scrubbed; various neat lockers economized space; a complication of white cordage in the corner showed that a hanging chair, that most comfortable of seats, was being made; and hammocks lashed up with seven perfectly even turns and covered with a rug formed a not inelegant sofa. Jack Aubrey had spent most of his naval life in quarters very much more confined than this; he had also a good deal of experience of French and American prisons, to say nothing of English sponging houses, and it would have been a hard gaol indeed that found him at a loss.

The power of a volcano is no match for the power of a soul mate. The love of soul mates is not always romantic. It is eternal and unconditional, it transcends time and space, yet it can be the love of parent and child, of best friends, of siblings, of grandparents or cousins, or many other platonic forms. Perhaps your soul mate is a college professor with whom you take a course, whose passion and knowledge for the subject he is teaching influences your own professional trajectory. Once you finish the course, you move on and so does he; your work together in this lifetime has been completed. We have families of souls, rather than just one soul mate, and we are being connected all the time. Sometimes it is only for mere moments, yet even this brief amount of time can change one’s life completely. Whether you are together for ten minutes, ten months, or ten years is not as important as the lessons that are learned, the directions, and the reminders that occur when these encounters happen.

In every collection of 10^10^122 cosmic patches, we thus expect there to be, on average, one patch that looks just like ours. That is, in every region of space that's roughly 10^10^122 meters across, there should be a cosmic patch that replicates ours-one that contains you, the earth, the galaxy, and everything else that inhabits our cosmic horizon.

Then, just as two trees are the same age if they have the same number of tree rings, and just as two samples of glacial sediment are the same age if they have the same percentage of radioactive carbon, two locations in space are passing through the same moment in time when they have the same value of the inflaton field. That's how we set and synchronize clocks in our bubble universe.

We don’t need to work a hundred hours a week at law firms and investment banks. We don’t need to socialize at cocktail parties. We do need to create a space for the J.D.s and Brians of the world to have a chance. I don’t know what the answer is, precisely, but I know it starts when we stop blaming Obama or Bush or faceless companies and ask ourselves what we can do to make things better.

Fiction is a set of observable manifestations, as represented and frozen in language, that triggers a profoundly subjective and individual experience. Ultimately, this is the kind of productive dilemma that can allow fiction to get to places that other media does not. Fiction is exceptionally good at providing models for consciousness, and at putting readers in a position to take upon themselves the structure of another consciousness for a short while. It is better at this than any other genre or media, and can do it in any number of modes (realistic or metafictional, reliably or unreliably, representationally or metafictionally, etc.). But for it to be able to do this as well as it possibly can, it must clear a space. This is where, for me, doing without becomes most crucial. The subtractions that we find in innovative fictions (even when those subtractions, as in Joyce's work, are followed by further ornamentations and encrustations) are there to facilitate the simulation of consciousness. What is subtracted is the significance and meaning designed to let us classify an experience without entering into it. Doing without such things opens the door wider for experience, putting the reader in a position where they are experiencing fiction in lieu of understanding it. By paying more attention to what we leave out than to how readers are going to interpret or work after the fact, we refuse to let fiction be assimilable, digestible, and safe. We keep it from being mere fodder for criticism and instead accept it as valid, vital experience.

So at my old school,” he said. “There was this kid on the baseball team. People thought, I don’t know. They saw that he went to some website or something.” ... “They made it impossible for him to play. Every day, the found another way to mess with him. Then one Friday after school, they locked him in the storage closet.” He winced, as if remembering and I knew. I knew then. “All night long and the whole next day. A tiny, dark, disgusting airless space. His parents thought he was at the away game and someone told the coaches he was sick, so no one even looked for him. No one knew he was trapped in there.” His chest was heaving and I was remembering how he told me he didn’t used to have claustrophobia and now he did. “He was really good too, probably the best player on the team or could have been. And he didn’t even do anything. The guy just went to these sites and someone saw. Do you get it? Do you get what it would mean for me? The assistant captain? I want to be captain next year so maybe I can graduate early. No scholarship. No nothing. These guys aren’t” - he made finger quotes - “evolved. They’re not from Northern California. They don’t do all-day sits or draw pictures.” The dagger went straight in. “It’s brutal in a locker room.

Just as important, the energy released by the inflaton field isn't lost-instead, like a cooling vat of steam condensing into water droplets, the inflaton's energy condenses into a uniform bath of particles that fill space. This two-step process-brief but rapid expansion, followed by energy conversion to particles-results in a huge, uniform spatial expanse that's filled with the raw material of familiar structures like stars and galaxies.

Within the modified equations, Kaluza found the ones Einstein had already used successfully to describe gravity in the familiar three dimensions of space and one of time. But because his new formulation included an additional dimension of space, Kaluza found an additional equation. Lo and behold, when Kaluza derived this equation he recognized it as the very one Maxwell had discovered half a century earlier to describe the electromagnetic field.

Wed don't need to live like the elites of California, New York, or Washington, D.C. We don't need to work a hundred hours a week at law firms and investment banks. We don't need to socialize at cocktail parties. We do need to create a space for the J.D.s and Brians of the world to have a chance. I don't know what the answer is, precisely, but I know it starts when we stop blaming Obama or Bush or faceless companies and ask ourselves what we can do make things better.

Not long ago I was watching the film A Story Worth Living with my sons. The film concludes with everyone enjoying a lovely Colorado evening at twilight. The characters sit in a circle around a fire. The discussion is about wholeness and the soul’s longing for a time of complete restoration and what that might be like. “That nothing is between me and any other person—no misunderstanding” was how one character described this wholeness. Another added, “That everything I have lost will be returned.” Nods of approval and expressions of affirmation filled in the space. Then another spoke: “That nothing is lost and that there are no more good-byes.” This is shalom. This is what we were made for. It is how life is supposed to be for us. This is humanity in its glory, but it waits. It cannot be while we live fallen. And perhaps it cannot fully be realized until the Savior’s return—but we can have so much more right now than we might realize.

But as the seventeenth century wore on, precision observations greatly improved due to the invention of the telescope and an increasingly mature application of mathematics to describe the data, and led a host of astronomers and mathematicians – including Johannes Kepler, Galileo and ultimately Isaac Newton – towards an understanding of the workings of the solar system. This theory is good enough even today to send space probes to the outer planets with absolute precision.

String theorists have found special pairs of geometrical shapes for space that have completely different features when each is probed by unwrapped strings. They also have completely different features when each is probed by wrapped strings. But-and this is the punch line-when probed both ways, with wrapped and unwrapped strings, the shapes become indistinguishable. what the unwrapped strings see on one space, the wrapped strings see on the other, and vice versa, rendering identical the collective picture gleaned from the full physics of string theory.

I remember the words of the great physicist Albert Einstein: A human being is part of the whole we call the universe, a part limited in time and space. He experiences himself in his thoughts and feelings as something separated from the rest . . . a kind of optical illusion of his consciousness. This illusion is a prison for us, restricting us to our personal desires and to affection for only the few people nearest us. Our task must be to free ourselves from this prison by widening our circle of compassion, to embrace all living beings and all of nature. We

Kaluza revealed that in a universe with an additional dimension of space, gravity and electromagnetism can both be described in terms of spatial ripples. Gravity ripples through the familiar three spatial dimensions, while electromagnetism ripples through the fourth. An outstanding problem with Kaluza's proposal was to explain why we don't see this fourth spatial dimension. It was here that Klein made his mark by suggesting the resolution explained above: dimensions beyond those we directly experience can elude our senses and our equipment if they're sufficiently small.

Consider, Maldacena says, a stack of three-branes, so closely spaced that they appear as a single monolithic slab-Figure 9.4-and study the behavior of strings moving in this environment. You'll recall that there are two types of strings-open snippets and closed loops-and that the end-points of open strings can move within and through branes but not off them, while closed strings have no ends and so can move freely through the entire spatial expanse. In the jargon of the field, we say that while open strings are confined to the branes, closed strings can move through the bulk of space.

Brian discovers that this first group features two bricklayers, a machinist, a doctor, a gun-store owner, a veterinarian, a plumber, a barber, an auto mechanic, a farmer, a fry cook, and an electrician. The second group—Brian thinks of them as the Dependents—features the sick, the young, and all the white-collar workers with obscure administrative backgrounds. These are the former middle managers and office drones, the paper pushers and corporate executives who once pulled down six-figure incomes running divisions of huge multinationals—now just taking up space, as obsolete as cassette tapes.

Whatever the water touched was riparian: that moist layer of air and rich earth along the shore was an Eden for many forms of life. Some drowned in a daily flood, while those that knew how, thrived. There was something riparian too about the people who spent most of their time on the water. Those whose language and equilibrium had been dictated by the elements around them. Who’d learned to hang on in the ever-shifting swell and drift of water under their feet. Contrast and contradictions abounded for those who had learned to meander despite limited space or to be still in the midst of all that rocking.

A hundred billion years from now, any galaxies not now resident in our neighborhood (a gravitationally bound cluster of about a dozen galaxies called our “local group”) will exit our cosmic horizon and enter a realm permanently beyond our capacity to see unless future astronomers have records handed down to them from an earlier era, their cosmological theories will seek explanations for an island universe, with galaxies numbering no more than students in a backwoods school, floating in a static sea of darkness. We live in a privileged age. Insights the universe giveth, accelerated expansion will taketh away.

And so we've come to a conclusion that's both general and provocative. Reality in an infinite cosmos is not what most of us would expect. At any moment in time, the expanse of space contains an infinite number of separate realms-constituents of what I'll call the Quilted Multiverse-with our observable universe, all we see in the vast night sky, being but one member. Canvassing this infinite collection of separate realms, we find that particle arrangements necessarily repeat infinitely many times. The reality that holds in any given universe, including ours, is thus replicated in an infinite number of other universes across the Quilted Multiverse.

Prior to these results, physicists had reasoned that since the Planck length (10^33) centimeters) was apparently the shortest length for which the notion of "distance" continues to have meaning, the smallest meaningful volume would be a tiny cube whose edges were each one Planck length long (a volume of 10^-99) cubic centimeters). A reasonable conjecture, widely believed, was that irrespective of future technological breakthroughs, the smallest possible volume could store no more than the smallest unit of information-one bit. And so the expectation was that a region of space would max out its information storage capacity when the number of bits it contained equaled the number of Planck cubes that could fit inside it. That Hawking's result involved the Planck length was therefore not surprising. The surprise was that the black hole's storehouse of hidden information was determined by the number of Planck-sized squares covering its surface and not by the number of Planck-sized cubes filling its volume. This was the first hint of holography-information storage capacity determined by the area of a bounding surface and not by the volume interior to that surface . Through twists and turns across three subsequent decades, this hint would evolve into a dramatic new way of thinking about the laws of physics.

gravitational waves are fundamentally different. Not only is a gravitational wave a side-to-side, lateral wave like light, not a longitudinal wave like sound, but it isn’t a ripple through objects in spacetime; it passes through spacetime itself. When a gravitational wave passes by, spacetime squeezes and contracts. This oscillation influences matter, which exists in spacetime – but doesn’t require matter to be able to travel. It’s quite demeaning to gravitational waves to call their detection ‘hearing the sound of black holes in space’ as some have done. By comparison, sound is a trivial local effect. Gravitational waves make the universe itself vibrate.

why Newton’s apple fell. The apple isn’t moving at all at the start of the process, so why would changing the shape of space make it move? The wonderful answer is that massive objects don’t just warp space, they warp space and time. In Einstein’s world, space and time are united into the single entity, spacetime. In principle we should think of spacetime as a four-dimensional object – but that’s hard to envisage, so what we tend to do is to just use two space dimensions and one of time. (The third space dimension hasn’t gone away, we just don’t need to think of it.) When we speak of warping space or time, what happens is that the axis is no longer straight, but starts to curve.

Megan Meade’s Guide to the McGowan Boys Entry One Observation #1: When they’re beautiful, they know they’re beautiful. Like the second-to-oldest one, Evan. He’s a senior. He is perfection personified. And he knows it. You can tell because he just sort of smiles knowingly when you gape at him. Not that I’ve been gaping at him. Not at all. Anyway, too soon yet to tell if it negatively affects his behavior. (Like Mike Blukowsi and his Astrodome-sized ego problem.) Observation #2: They like skin. Especially skin they think they’re not necessarily supposed to be seeing. Like the space between your belly tee and your waistband. Observation #3: They have no problem bringing up events that would mortify me into shamed silence if the roles were reversed. Like Evan totally brought up the wiffleball bat incident, when if that had happened to me, I’d be wishing on every one of my birthday cakes for everyone to forget it. Observation #4: They gossip. Can you believe it? I overheard Finn and Doug in the backyard talking about some girl named Dawn who blew off some guy named Simon for some other guy named Rick for like TWENTY MINUTES! They sounded like those old mole-hair ladies at Sal’s Milkshakes. ‘Member the ones who lectured us for a whole hour that day about how young women shouldn’t wear shorts? Wait, okay, I got sidetracked. Observation #5: The older ones are so cute with the younger ones. They were playing ultimate Frisbee when I first got here and Evan totally let Caleb and Ian tackle him. It was soooooo cute. **sigh.** Observation #6: They’re cliquey. I mean, eye-rolling, secret-handshake, don’t-talk-to-us-unless-you’ve-got-an-X-and-a-Y cliquey. Very schooled in the art of the freeze-out. Observation #7: They have no sense of personal space. I need a lock on my door. STAT. Observation #8: Boys are icky. Do not even get me started on the state of the bathroom. I’m thinking of calling in a haz-mat team. Seriously. Observation #9: They have really freaky things going on down there. Yeah, I don’t think I’m ready to elaborate on that one yet. Observation #10: They know how to make enemies. Big time.

I feel abnormally aware of the air in my lungs and of the blood in my body. Brian’s breath is loud and reminds me that he is a person and that he is alive and so am I. I put his hand on my throat to stop my breath and try to subdue this feeling of being a person who breathes and takes up space and fucks people, but he won’t keep his hand there. He moves it to my waist and kisses my forehead. I feel a cold rush down my body and suddenly I’m panicked. I wonder if Brian has ever been with a girl who loved him before. I wonder if there is a person out in the world who would feel sick at the thought of him being naked with me. I cannot shake this thought. I become sure of it. I suddenly feel a sickening, overwhelming guilt. I have to close my eyes to stop from crying at the thought of the girl I have imagined.

Care is in order, because the very beginning – by which we mean the events that happened during the Planck epoch – the time period before a million million million million million million millionths of a second after the Big Bang, is currently beyond our understanding. This is because we lack a theory of space and time before this point, and consequently have very little to say about it. Such a theory, known as quantum gravity, is the holy grail of modern theoretical physics and is being energetically searched for by hundreds of scientists across the world. (Albert Einstein spent the last decades of his life searching in vain for it.) Conventional thinking holds that both time and space began at time zero, the beginning of the Planck era. The Big Bang can therefore be regarded as the beginning of time itself, and as such it was the beginning of the Universe.

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).

One find in Western Australia turned up zircon crystals dated to 4.4 billion years ago, just a couple of hundred million years after the earth and the solar system formed. By analyzing their detailed composition, researchers have suggested that ancient conditions may have been far more agreeable than previously thought. Early earth may have been a relatively calm water world, with small landmasses dotting a surface mostly covered by ocean.15 That’s not to say that earth’s history didn’t have its moments of flaming drama. Roughly fifty to one hundred million years after its birth, earth likely collided with a Mars-sized planet called Theia, which would have vaporized the earth’s crust, obliterated Theia, and blown a cloud of dust and gas thousands of kilometers into space. In time, that cloud would have clumped up gravitationally to form the moon, one of the larger planetary satellites in the solar system and a nightly reminder of that violent encounter. Another reminder is provided by the seasons. We experience hot summers and cold winters because earth’s tilted axis affects the angle of incoming sunlight, with summer being a period of direct rays and winter being a period of oblique ones. The smashup with Theia is the likely cause of earth’s cant. And though less sensational than a planetary collision, both the earth and the moon endured periods of significant pummelings by smaller meteors. The moon’s lack of eroding winds and its static crust have preserved the scars but earth’s thrashing, less visible now, was just as severe. Some early impacts may have partially or even fully vaporized all water on earth’s surface. Despite that, the zircon archives provide evidence that within a few hundred million years of its formation, earth may have cooled sufficiently for atmospheric steam to rain down, fill the oceans, and yield a terrain not all that dissimilar from the earth we now know. At least, that’s one conclusion reached by reading the crystals.

But, as I indicated in the historical overview, many of these same physicists quickly realized that the story for nature's remaining force, gravity, was far subtler. Whenever the equations of general relativity commingled with those of quantum theory, the mathematics balked. Use the combined equations to calculate the quantum probability of some physical process- such as the chance of two electrons ricocheting off each other, given both their electromagnetic repulsion and their gravitational attraction-and you'd typically get the answer infinity. While some things in the universe can be infinite, such as the extent of space and the quantity of matter that may fill it, probabilities are not among them. By definition, the value of a probability must be between 0 and 1 (or, in terms of percentages, between 0 and 100). An infinite probability does not mean that something is very likely to happen, or is certain to happen; rather, it's meaningless, like speaking of the thirteenth egg in an even dozen. An infinite probability sends a clear mathematical message: the combined equations are nonsense.

Rμv– 1/2 gμv R = 8πTμv The left side of the equation starts with the term Rμv, which is the Ricci tensor he had embraced earlier. The term gμv is the all-important metric tensor, and the term R is the trace of the Ricci tensor called the Ricci scalar. Together, this left side of the equation—which is now known as the Einstein tensor and can be written simply as Gμv—compresses together all of the information about how the geometry of spacetime is warped and curved by objects. The right side describes the movement of matter in the gravitational field. The interplay between the two sides shows how objects curve spacetime and how, in turn, this curvature affects the motion of objects. As the physicist John Wheeler has put it, “Matter tells spacetime how to curve, and curved space tells matter how to move.”83 Thus is staged a cosmic tango, as captured by another physicist, Brian Greene: Space and time become players in the evolving cosmos. They come alive. Matter here causes space to warp there, which causes matter over here to move, which causes space way over there to warp even more, and so on. General relativity provides the choreography for an entwined cosmic dance of space, time, matter, and energy.84 At

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.

The result was not nearly as vivid to the layman as, say, E=mc2. Yet using the condensed notations of tensors, in which sprawling complexities can be compressed into little subscripts, the crux of the final Einstein field equations is compact enough to be emblazoned, as it indeed often has been, on T-shirts designed for proud physics students. In one of its many variations,82 it can be written as: Rμv– 1/2 gμv R = 8πTμv The left side of the equation starts with the term Rμv, which is the Ricci tensor he had embraced earlier. The term gμv is the all-important metric tensor, and the term R is the trace of the Ricci tensor called the Ricci scalar. Together, this left side of the equation—which is now known as the Einstein tensor and can be written simply as Gμv—compresses together all of the information about how the geometry of spacetime is warped and curved by objects. The right side describes the movement of matter in the gravitational field. The interplay between the two sides shows how objects curve spacetime and how, in turn, this curvature affects the motion of objects. As the physicist John Wheeler has put it, “Matter tells spacetime how to curve, and curved space tells matter how to move.”83 Thus is staged a cosmic tango, as captured by another physicist, Brian Greene: Space and time become players in the evolving cosmos. They come alive. Matter here causes space to warp there, which causes matter over here to move, which causes space way over there to warp even more, and so on. General relativity provides the choreography for an entwined cosmic dance of space, time, matter, and energy.

We are a species that delights in story. We look out on reality, we grasp patterns, and we join them into narratives that can captivate, inform, startle, amuse, and thrill. The plural—narratives—is utterly essential. In the library of human reflection, there is no single, unified volume that conveys ultimate understanding. Instead, we have written many nested stories that probe different domains of human inquiry and experience: stories, that is, that parse the patterns of reality using different grammars and vocabularies. Protons, neutrons, electrons, and nature’s other particles are essential for telling the reductionist story, analyzing the stuff of reality, from planets to Picasso, in terms of their microphysical constituents. Metabolism, replication, mutation, and adaptation are essential for telling the story of life’s emergence and development, analyzing the biochemical workings of remarkable molecules and the cells they govern. Neurons, information, thought, and awareness are essential for the story of mind—and with that the narratives proliferate: myth to religion, literature to philosophy, art to music, telling of humankind’s struggle for survival, will to understand, urge for expression, and search for meaning. These are all ongoing stories, developed by thinkers hailing from a great range of distinct disciplines. Understandably so. A saga that ranges from quarks to consciousness is a hefty chronicle. Still, the different stories are interlaced. Don Quixote speaks to humankind’s yearning for the heroic, told through the fragile Alonso Quijano, a character created in the imagination of Miguel de Cervantes, a living, breathing, thinking, sensing, feeling collection of bone, tissue, and cells that, during his lifetime, supported organic processes of energy transformation and waste excretion, which themselves relied on atomic and molecular movements honed by billions of years of evolution on a planet forged from the detritus of supernova explosions scattered throughout a realm of space emerging from the big bang. Yet to read Don Quixote’s travails is to gain an understanding of human nature that would remain opaque if embedded in a description of the movements of the knight-errant’s molecules and atoms or conveyed through an elaboration of the neuronal processes crackling in Cervantes’s mind while writing the novel. Connected though they surely are, different stories, told with different languages and focused on different levels of reality, provide vastly different insights.

The remaining part of the first description consist of low-energy open strings moving on the three-branes. We recall from Chapter 4 that low-energy strings are well described by point particle quantum field theory, and that is the case here. The particular kind of quantum field theory involves a number of sophisticated mathematical ingredients (and it has an ungainly characterization: conformally invariant supersymmetric quantum gauge field theory), but two vital characteristics are readily understood. The absence of closed strings ensures the absence of the gravitational field. And, because the strings can move only on the tightly sandwiched three-dimensional branes, the quantum field theory lives in three spatial dimensions (in addition to the one dimension of time, for a total of four spacetime dimensions). The remaining part of the second description consists of closed strings, executing any vibrational pattern, as long as they are close enough to the black branes' event horizon to appear lethargic-that is, to appear to have low energy. Such strings, although limited in how far they stray from the black stack, still vibrate and move through nine dimensions of space (in addition to one dimension of time, for a total of ten spacetime dimensions). And because this sector is built from closed strings, it contains the force of gravity. However different the two perspectives might seem, they're describing one and the same physical situation, so they must agree. This leads to a thoroughly bizarre conclusion. A particular nongravitational, point particle quantum field theory in four spacetime dimensions (the first perspective) describes the same physics as strings, including gravity, moving through a particular swath of ten spacetime dimensions (the second perspective). This would seem as far-fetched as claiming...Well, honestly, I've tried, and I can't come up with any two things int he real world more dissimilar than these two theories. But Maldacena followed the math, in the manner we've outlined, and ran smack into this conclusion. The sheer strangeness of the result-and the audacity of the claim-isn't lessened by the fact that it takes but a moment to place it within the line of thought developed earlier in this chapter. As schematically illustrated in Figure 9.5, the gravity of the black brane slab imparts a curved shape to the ten-dimensional spacetime swath in its vicinity (the details are secondary, but the curved spacetime is called anti-de Sitter five-space times the five sphere); the black brane is itself the boundary of this space. And so, Maldacena's result is that string theory within the bulf of this spacetime shape is identical to a quantum field theory living on its boundary. This is holography come to life.

So what was this reincarnated ether, and what did it mean for Mach’s principle and for the question raised by Newton’s bucket?* Einstein had initially enthused that general relativity explained rotation as being simply a motion relative to other objects in space, just as Mach had argued. In other words, if you were inside a bucket that was dangling in empty space, with no other objects in the universe, there would be no way to tell if you were spinning or not. Einstein even wrote to Mach saying he should be pleased that his principle was supported by general relativity. Einstein had asserted this claim in a letter to Schwarzschild, the brilliant young scientist who had written to him from Germany’s Russian front during the war about the cosmological implications of general relativity. “Inertia is simply an interaction between masses, not an effect in which ‘space’ of itself is involved, separate from the observed mass,” Einstein had declared.23 But Schwarzschild disagreed with that assessment. And now, four years later, Einstein had changed his mind. In his Leiden speech, unlike in his 1916 interpretation of general relativity, Einstein accepted that his gravitational field theory implied that empty space had physical qualities. The mechanical behavior of an object hovering in empty space, like Newton’s bucket, “depends not only on relative velocities but also on its state of rotation.” And that meant “space is endowed with physical qualities.” As he admitted outright, this meant that he was now abandoning Mach’s principle. Among other things, Mach’s idea that inertia is caused by the presence of all of the distant bodies in the universe implied that these bodies could instantly have an effect on an object, even though they were far apart. Einstein’s theory of relativity did not accept instant actions at a distance. Even gravity did not exert its force instantly, but only through changes in the gravitational field that obeyed the speed limit of light. “Inertial resistance to acceleration in relation to distant masses supposes action at a distance,” Einstein lectured. “Because the modern physicist does not accept such a thing as action at a distance, he comes back to the ether, which has to serve as medium for the effects of inertia.”24 It is an issue that still causes dispute, but Einstein seemed to believe, at least when he gave his Leiden lecture, that according to general relativity as he now saw it, the water in Newton’s bucket would be pushed up the walls even if it were spinning in a universe devoid of any other objects. “In contradiction to what Mach would have predicted,” Brian Greene writes, “even in an otherwise empty universe, you will feel pressed against the inner wall of the spinning bucket… In general relativity, empty spacetime provides a benchmark for accelerated motion.

it is likely that even if string theory is right, no one ever will. Strings are so small that a direct observation would be tantamount to reading the text on this page from a distance of 100 light-years: it would require resolving power nearly a billion billion times finer than our current technology allows. Some scientists argue vociferously that a theory so removed from direct empirical testing lies in the realm of philosophy or theology, but not physics.

Airbnb’s strategy for photographing its hosts’ rooms offers an instructive example. Early on, Airbnb’s founders discovered that one of the key factors that increased the chances of renting a room on Airbnb was the quality of the photographs of that room. It turns out that most of us aren’t professional photographers, and our poorly composed, poorly shot cell phone pictures don’t do a good job of conveying the awesomeness of our living spaces. So the founders took to the road, visiting hosts and taking photographs for them. Obviously, personally visiting every host was hardly a scalable solution, so the the task was soon outsourced to freelance photographers. As Airbnb grew, the strategy shifted from the founders managing a short list of photographers, to an employee managing a large group of photographers, to an automated system managing a global network of photographers. Founder Brian Chesky describes this strategy succinctly: “Do everything by hand until it’s too painful, then automate it.

However, the molasses metaphor has three misleading features that you should be aware of.
