On meditation and the birth of the universe.

On meditation and the birth of the universe.

This is part of a series of essays prepared to discuss in jail.

Our bodies are chaos engines. 

In our nearby environment, we produce order.  We form new memories.  We build things.  We might have sex and create new life.  From chaos, structure.

As we create local order, though, we radiate disorder into the universe. 

The laws of physics work equally well whether time is moving forward or backward.  The only reason we experience time as flowing forward is that the universe is progressing from order into chaos.

In the beginning, everything was homogeneous.  The same stuff was present everywhere.  Now, some regions of the universe are different from others.  One location contains our star; another location, our planet.  Each of our bodies is very different from the space around us.

This current arrangement is more disorderly than the early universe, but less so than what our universe will one day become.  Life is only possible during this intermediate time, when we are able to eat structure and excrete chaos.

Sunlight shines on our planet – a steady stream of high-energy photons all pointed in the same direction.  Sunshine is orderly.  But then plants eat sunshine and carbon dioxide to grow.  Animals eat the plants.  As we live, we radiate heat – low-energy photons that spill from our bodies in all directions.

The planet Earth, with all its life, acts like one big chaos engine.  We absorb photons from the sun, lower their energy, increase their number, and scatter them.

We’ll continue until we can’t.

Our universe is mostly filled with empty space. 

But empty space does not stay empty.  Einstein’s famous equation, E equals M C squared, describes the chance that stuff will suddenly pop into existence.  This happens whenever a region of space gathers too much energy.

Empty space typically has a “vacuum energy” of one billionth of a joule per cubic meter.  An empty void the size of our planet would have about as much energy as a teaspoon of sugar.  Which doesn’t seem like much.  But even a billionth of a joule is thousands of times higher than the energy needed to summon electrons into being.

And there are times when a particular patch of vacuum has even more energy than that.

#

According to the Heisenberg Uncertainty Principle, time and energy can’t be defined simultaneously.  Precision in time causes energy to spread – the energy becomes both lower and higher than you expected.

In practice, the vacuum energy of a particular region of space will seem to waver.  Energy is blurry, shimmering over time.

There are moments when even the smallest spaces have more than enough energy to create new particles.

Objects usually appear in pairs: a particle and its anti-particle.  Anti-matter is exactly like regular matter except that each particle has an opposite charge.  In our world, protons are positive and electrons are negative, but an anti-proton is negative and an anti-electron is positive.

If a particle and its anti-particle find each other, they explode.

When pairs of particles appear, they suck up energy.  Vacuum energy is stored inside them.  Then the particles waffle through space until they find and destroy each other.  Energy is returned to the void.

This constant exchange is like the universe breathing.  Inhale: the universe dims, a particle and anti-particle appear.  Exhale: they explode.

#

Our universe is expanding.  Not only are stars and galaxies flying away from each other in space, but also empty space itself is growing.  The larger a patch of nothingness, the faster it will grow.  In a stroke of blandness, astronomers named the force powering this growth “dark energy.”

Long ago, our universe grew even faster than it does today.  Within each small fraction of a second, our universe doubled in size.  Tiny regions of space careened apart billions of times faster than the speed of light.

This sudden growth was extremely improbable.  For this process to begin, the energy of a small space had to be very, very large.  But the Heisenberg Uncertainty Principle claims that – if we wait long enough – energy can take on any possible value.  Before the big bang, our universe had a nearly infinite time to wait.

After that blip, our universe expanded so quickly because the vacuum of space was perched temporarily in a high-energy “metastable” state.  Technically balanced, but warily.  Like a pencil standing on its tip.  Left alone, it might stay there forever, but the smallest breath of air would cause this pencil to teeter and fall.

Similarly, a tiny nudge caused our universe to tumble back to its expected energy.  A truly stable vacuum.  The world we know today was born – still growing, but slowly.

#

During the time of rapid expansion, empty vacuum had so much energy that particles stampeded into existence.  The world churned with particles, all so hot that they zipped through space at nearly the speed of light. 

For some inexplicable reason, for every billion pairs of matter and anti-matter, one extra particle of matter appeared.  When matter and anti-matter began to find each other and explode, this billionth extra bit remained.

This small surplus formed all of stars in the sky.  The planets.  Ourselves.

#

Meditation is like blinking.  You close your eyes, time passes, then you open your eyes again.  Meditation is like a blink where more time passes.

But more is different.

#

Our early universe was filled with the smallest possible particles.  Quarks, electrons, and photons.  Because their energy was so high, they moved too fast to join together.  Their brilliant glow filled the sky, obscuring our view of anything that had happened before.

As our universe expanded, it cooled.  Particles slowed down.  Three quarks and an electron can join to form an atom of hydrogen.  Two hydrogen atoms can join to form hydrogen gas.  And as you combine more and more particles together, your creations can be very different from a hot glowing gas.  You can form molecules, cells, animals, societies.

#

When a cloud of gas is big enough, its own gravity can pull everything inward.  The cloud becomes more and more dense until nuclear fusion begins, releasing energy just like a nuclear bomb.  These explosions keep the cloud from shrinking further.

The cloud has become a star.

Nuclear fusion occurs because atoms in the center of the cloud are squooshed too close together.  They merge: a few small atoms become one big atom.  If you compared their weights – four hydrogens at the start, one helium at the finish – you’d find that a tiny speck of matter had disappeared.  And so, according to E equals M C squared, it released a blinding burst of energy.

The largest hydrogen bomb detonated on Earth was 50 megatons – the Kuz’kina Mat tested in Russia in October, 1961.  It produced a mushroom cloud ten times the height of Mount Everest.  This test explosion destroyed houses hundreds of miles away.

The fireball of Tsar Bomba, the Kuz’kina Mat.

Every second, our sun produces twenty billion times more energy than this largest Earth-side blast.

#

Eventually, our sun will run out of fuel.  Our sun shines because it turns hydrogen into helium, but it is too light to compress helium into any heavier atoms.  Our sun has burned for about four billion years, and it will probably survive for another five billion more.  Then the steady inferno of nuclear explosions will end.

When a star exhausts its fuel, gravity finally overcomes the resistance of the internal explosions.  The star shrinks.  It might crumple into nothingness, becoming a black hole.  Or it might go supernova – recoiling like a compressed spring that slips from your hand – and scatter its heavy atoms across the universe.

Planets are formed from the stray viscera of early stars.

#

Our universe began with only hydrogen gas.  Every type of heavier atom – carbon, oxygen, iron, plutonium – was made by nuclear explosions inside the early stars.

When a condensing cloud contains both hydrogen gas and particulates of heavy atoms, the heavy atoms create clumps that sweep through the cloud far from its center.  Satellites, orbiting the star.  Planets.

Nothing more complicated than atoms can form inside stars.  It’s too hot – the belly of our sun is over twenty million degrees.  Molecules would be instantly torn apart.  But planets – even broiling, meteor-bombarded planets – are peaceful places compared to stars.

Molecules are long chains of atoms.  Like atoms, molecules are made from combinations of quarks and electrons.  The material is the same – but there’s more of it.

More is different.

Some atoms have an effect on our bodies.  If you inhale high concentrations of oxygen – an atom with eight protons – you’ll feel euphoric and dizzy.  If you drink water laced with lithium – an atom with three protons – your brain might become more stable.

But the physiological effects of atoms are crude compared to molecules.  String fifty-three atoms together in just the right shape – a combination of two oxygens, twenty-one carbons, and thirty hydrogens – and you’ll have tetrahydrocannibol.  String forty-nine atoms together in just the right shape – one oxygen, three nitrogens, twenty carbons, and twenty-five hydrogens – and you’ll have lysergic acid diethylamide.

The effects of these molecules are very different from the effects of their constituent parts.  You’d never predict what THC feels like after inhaling a mix of oxygen, carbon, and hydrogen gas.

#

An amino acid is comparable in scale to THC or LSD, but our bodies aren’t really made of amino acids.  We’re built from proteins – anywhere from a few dozen to tens of thousands of amino acids linked together.  Proteins are so large that they fold into complex three-dimensional shapes.  THC has its effect because some proteins in your brain are shaped like catcher’s mitts, and the cannibinoid nestles snuggly in the pocket of the glove.

Molecules the size of proteins can make copies of themselves.  The first life-like molecules on Earth were long strands of ribonucleic acid – RNA.  A strand of RNA can replicate as it floats through water.  RNA acts as a catalyst – it speeds up the reactions that form other molecules, including more RNA.

Eventually, some strands of RNA isolated themselves inside bubbles of soap.  Then the RNA could horde – when a particular sequence of RNA catalyzed reactions, no other RNA would benefit from the molecules it made.  The earliest cells were bubbles that could make more bubbles.

Cells can swim.  They eat.  They live and die.  Even single-celled bacteria have sex: they glom together, build small channels linking their insides to each other, and swap DNA.

But with more cells, you can make creatures like us.

Consciousness is an emergent property.  With a sufficient number of neuron cells connected to each other, a brain is able to think and plan and feel.  In humans, 90 billion neuron cells direct the movements of a 30-trillion-cell meat machine.

Humans are such dexterous clever creatures that we were able to discover the origin of our universe.  We’ve dissected ourselves so thoroughly that we’ve seen the workings of cells, molecules, atoms, and subatomic particles.

But a single human animal, in isolation, never could have learned that much.

Individual humans are clever, but to form a culture complex enough to study particle physics, you need more humans.  Grouped together, we are qualitatively different.  The wooden technologies of Robinson Crusoe, trapped on a desert island, bear little resemblance to the vaulted core of a particle accelerator.

English writing uses just 26 letters, but these can be combined to form several hundred thousand different words, and these can be combined to form an infinite number of different ideas.

More is different.  The alphabet alone couldn’t give anyone insight into the story of your life.

Meditation is like a blink where more time passes, but the effect is very different.

Many religions praise the value of meditation, especially in their origin stories.  Before Jesus began his ministry, he meditated for 40 days in the Judaean Desert – his mind’s eye saw all the world’s kingdoms prostrate before him, but he rejected that power in order to spread a philosophy of love and charity. 

Before Buddha began his ministry, he meditated for 49 days beneath the Bodhi tree – he saw a path unfurl, a journey that would let travelers escape our world’s cycle of suffering. 

Before Odin began his ministry, he meditated for 9 days while hanging from a branch of Yggdrasil, the world tree – Odin felt that he died, was reborn, and could see the secret language of the universe shimmering beneath him. 

The god Shiva meditated in graveyards, smearing himself with crematory ash.

At its extreme, meditation is purportedly psychedelic.  Meditation can induce brain states that are indistinguishable from LSD trips when visualized by MRI.  Meditation isolates the brain from its surroundings, and isolation can trigger hallucination.

Researchers have found that meditation can boost our moods, attentiveness, cognitive flexibility, and creativity.  Our brains are plastic – changeable.  We can alter the way we experience the world.  Many of our thoughts are the result of habit.  Meditation helps us change those habits.  Any condition that is rooted in our brain – like depression, insomnia, chronic pain, or addiction – can be helped with meditation.

To meditate, we have to sit, close our eyes, and attempt not to think.  This is strikingly difficult.  Our brains want to be engaged.  After a few minutes, most people experience a nagging sense that we’re wasting time.

But meditation gives our minds a chance to re-organize.  To structure ourselves.  And structure is the property that allows more of something to become different.  Squirrels don’t form complex societies – a population of a hundred squirrels will behave similarly to a population of a million or a billion.  Humans form complex webs of social interactions – as our numbers grew through history, societies changed in dramatic ways.

Before there was structure, our entire universe was a hot soup of quarks and electrons, screaming through the sky.  Here on Earth, these same particles can be organized into rocks, or chemicals, or squirrels, or us.  How we compose ourselves is everything.

The easiest form of meditation uses mantras – this is sometimes called “transcendental meditation” by self-appointed gurus who charge people thousands of dollars to participate in retreats.  Each attendee is given a “personalized” mantra, a short word or phrase to intone silently with every breath.  The instructors dole mantras based on a chart, and each is Sanskrit.  They’re meaningless syllables to anyone who doesn’t speak the language.

Any two-syllable word or phrase should work equally well, but you’re best off carving something uplifting into your brain.  “Make peace” or “all one” sound trite but are probably more beneficial than “more hate.”  The Sanskrit phrase “sat nam” is a popular choice, which translates as “truth name” or more colloquially as “to know the true nature of things.”

The particular mantra you choose matters less than the habit – whichever phrase you choose, you should use it for every practice.  Because meditation involves sitting motionless for longer than we’re typically accustomed, most people begin by briefly stretching.  Then sit comfortably.  Close your eyes.  As you breathe in, silently think the first syllable of your chosen phrase.  As you breathe out, think the second.

Repeating a mantra helps to crowd out other thoughts, as well as distractions from your environment.  Your mind might wander – if you catch yourself, just try to get back to repeating your chosen phrase.  No one does it perfectly, but practice makes better.  When a meditation instructor’s students worried that their practice wasn’t good enough, he told them that “even on a shallow dive, you still get wet.”

In a quiet space, you might take a breath every three to six seconds.  In a noisy room, you might need to breathe every second, thinking the mantra faster to block out external sound.  The phrase is a tool to temporarily isolate your mind from the world.

Most scientific studies recommend you meditate for twenty minutes at a time, once or twice a day, each and every day.  It’s not easy to carve out this much time from our daily routines.  Still, some is better than nothing.  Glance at a clock before you close your eyes, and again after you open them.  Eventually, your mind will begin to recognize the passage of time.  After a few weeks of practice, your body might adopt the approximate rhythm of twenty minutes.

Although meditation often feels pointless during the first week of practice, there’s a difference between dabbling and a habit.  Routine meditation leads to benefits that a single experience won’t.

More is different.

On prayer, diversity among deities, and ADHD.

On prayer, diversity among deities, and ADHD.

My new favorite computer game begins each round as a real-time strategy game like Starcraft.  You command your little empire to build temples and offer up various sorts of psalms – will you praise your deity’s ever-gathering hands, its watchful vigilance, its fiery vengeance?

After you feel that you’ve done enough to celebrate your deity, you can command your priests to summon it – at which point the gameplay switches to a third-person adventure mode vaguely reminiscent of the old arcade classic Rampage.  You must attempt to destroy opposing civilizations with your deity … but there’s a twist.  The attributes of your deity reflect the way it was prayed to.  With too much emphasis on its “ever-gathering hands,” your god’s hands become massive. Those unwieldy appendages drag behind you as you walk, plowing deep furrows into the ground.

In this phase of the game, the controls can seem laggy and loose.  It turns out that this is intentional; as in the game Octodad, an inability to control your creation is an essential part of the game.  Certain types of prayer might make your deity more powerful but also more difficult to manage.

John_Martin_-_The_Great_Day_of_His_Wrath_-_Google_Art_Project

Presumably you’d avoid this sort of self-destructive excess – like praising wrath to the extent that your god destroys your own kingdom promptly after being summoned – but opposing players can infiltrate your civilization with heretics, and the way they pray will affect your god as well.

Arturo Perez-Reverte’s The Club Dumas ends with the idea that “everyone gets the devil he deserves.”  This is the underlying concept of the game, but for gods instead of demons.

First Coming includes elements of both real-time strategy and arcade smash-em-up.  And the idea of human prayer sculpting physically-manifest deities is intriguing.  I’d go so far as to argue that it’s the greatest game, flawed only in that it doesn’t live up to the Ontological Argument for the existence of God.

Bible_primer,_Old_Testament,_for_use_in_the_primary_department_of_Sunday_schools_(1919)_(14595468018)We live in a culture that reveres vengeance.  The majority of the U.S. worships a deity who was praised for his violence.

Sometime around 600 BCE, a kingdom that worshiped a local deity called Yahweh was conquered by Nebuchadnezzer, whose people worshiped the storm god Marduk.  After the surrender, many of the conquered people were deported to Babylon, where they would help make that city the most splendid in the world.

But some of the conquered Hebrews were allowed to remain in Jerusalem, where they still worshiped Yahweh in traditional ways – mostly by ritually killing animals – until they attempted to regain their independence.  Then the Babylonian king Nebuchadnezzer sent an army to circle the city.  The people began to starve.  The uprising was crushed.

102.Zedekiah's_Sons_Are_Slaughtered_before_His_EyesThe Hebrew leader was captured.  He was held, struggling, a soldier on either side restraining his arms.  One by one the Babylonian conquerors brought Zedekiah’s children.  The leader surely screamed, begging to die.  The soldiers gripped his arms more tightly.  And (2 Kings 25) they slew the sons of Zedekiah before his eyes, and put out the eyes of Zedekiah.  Those murders were his last sights, lingering in his blinded mind.  His sons bodies spilling blood from their slit necks into the dust.

Many more of the remaining Hebrews were then deported to Babylon, to slave for the greatness of that city.  They carted stones to build monuments to Marduk.  This god’s temples soared into the sky, one some seven stories high.

And the Hebrews saw the ceremonies held to celebrate Marduk.  On the fourth day of the New Year’s festival, priests read from a sacred text, the Enuma Elish, describing the origin of the world.  The old gods had sex; they were murdered by their children; the flesh of their bodies was used to construct heaven and earth.  Other sacred texts included the Atrahasis – which describes the flood that nearly destroyed humanity when we became too noisy and disturbed the gods’ rest – and Gilgamesh which celebrates fraternal love.

The-Rise-and-Fall-of-Adam-and-Eve_Stephen-Greenblatt_coverIn The Rise and Fall of Adam and Eve, Stephen Greenblat writes that “These works feature gods – a whole pantheon of them – but Yahweh is nowhere among them, let alone their lord and master.

The Hebrew people were crushed, their god so insignificant that he appeared in none of the victors’ stories.  And so the Hebrews fought back … with words.  They wrote a sacred text of their own, one in which Yahweh reigned supreme and the Babylonian tales were mockingly tweaked.  The glorious temples gave rise to “The Tower of Babel,” symbol of mankind’s unwarranted arrogance.  In the Hebrew flood story, humans were killed because the city people – and none were more urbane than the Babylonians – were corrupt.  Sex did not mark the origin of the world, but rather began after the fall.

And they sang psalms to a deity patiently waiting to enact murderous revenge:

By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion

We hanged our harps upon the willows in the midst thereof.

For there they that carried us away captive required of us a song; and they that wasted us required of us mirth, saying, Sing us one of the songs of Zion.

How shall we sing the Lord’s song in a strange land?

… and, in answer of their own question, the conquered people begin to sing …

If I forget thee, O Jerusalem, let my right hand forget her cunning.

If I do not remember thee, let my tongue cleave to the roof of my mouth; if I prefer not Jerusalem above my chief joy.

Remember, O Lord, the children of Edom in the day of Jerusalem; who said, Raze it, raze it, even to the foundation thereof.

O daughter of Babylon, who art to be destroyed; happy shall he be, that rewardeth thee as thou hath served us.

Happy shall he be, that taketh and dasheth thy little ones against the stones.

After the siege, Hebrew sons were murdered, daughters were raped, those of able body were made slaves.  They asked of their god revenge.  They prayed to a lord who would kill, and abet their killing, to restore their kingdom.

bible-1623181_640And … several millennia later … our philosophical traditions are rooted in their prayers.  Our nation is embroiled in retributive wars.  Our punitive prisons are overflowing, with those unfortunate enough to land inside often made worse by their time there.

Yahweh was praised for his patient pursuit of vengeance.  And we celebrate those qualities – in school, especially, we praise those able to dispassionately sit for hours, ingesting knowledge.  Those with difficulty sitting still, we drug.

Which is sad – there are many ways of being smart, even if our culture celebrates only one of them.

Indeed, many cultures have told myths with ADHD heros.  In the Apache myth of the origin of fire, Fox joined a flock of geese in flight … but then forgot the rules for staying in the air.  But that was okay – it was only after he tumbled to earth that he had a chance to steal fire from a tribe of fireflies and bring it to mankind.

In many Polynesian myths of the origin of fire, it was brought by Maui … whose impulsiveness would almost surely lead to an ADHD diagnosis in the contemporary United States.  Each time he received a gift of fire from his ancestor in the underworld – she was pulling off burning finger- or toe-nails and giving them to him – he intentionally quenched them in a nearby stream, just to see what she’d do next.  His curiosity was nearly the death of him.  Irked, she lit the world on fire.

In the Norse pantheon, Loki sometimes plans … but more often pursues whatever rebellious notion pops into his head.  The mutant children he sired will destroy the world.  His penchant for vicious barroom taunting (and impromptu murder) angered all other gods and led to his repeated exile from their kingdom.

But his exploits were still celebrated.

lightning.jpgOr there’s Annabeth in Rick Riordan’s The Lightning Thief, a daughter of Athena who helps the protagonist recover after a battle with a minotaur:

“And the ADHD – you’re impulsive, can’t sit still in the classroom.  That’s your battlefield reflexes.  In a real fight, they’d keep you alive.  As for the attention problems, that’s because you see too much, Percy, not too little.  Your senses are better than a regular mortal’s.  Of course the teachers want you medicated.  Most of them are monsters.  They don’t want you seeing them for what they are.”
