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.

1280px-Plasmid_(english).svgDNA plasmids are small loops of genetic information that can change the behavior of bacteria.  With the right (wrong?) plasmids, you could take innocuous E. coli and make it very dangerous.

As best I could tell from a few minutes spent skimming the USPS documents describing “hazardous, restricted, and perishable mail,” it’s not actually illegal to ship plasmids.  Many biomedical researchers have long assumed that it was illegal, though.  Not that we didn’t do it.  But we always took steps to sneakily circumvent the laws we assumed existed.

Plasmids are dangerous, after all.  Why wouldn’t there be a law?

DNA is very stable.  Its stability is probably the whole reason it exists.  Most scientists assume that life began as self-replicating strands of a molecule called RNA, which is very similar to DNA except more prone to falling apart.  Each of our cells is like a tiny factory – proteins are the machines, RNA are blueprints, and DNA is a file cabinet.

(K says this analogy is no good because a file cabinet is an “archaic technology.”  I have several early drafts of my novel – plus the entire three-year run of Evil Dave vs. Regular Dave – in a file cabinet next to our bed.  I wonder, am I an archaic technology?)

DNA is so stable that it can be dried out and shipped across the country without coming to any harm.

To send plasmids through the mail, we would draw a circle on a piece of filter paper, dab a liquid solution of it onto the paper, then slip the sheet into the center of a catalog.  The catalog would look harmless, like junk mail.  Whomever received it would flip through, find the filter paper, cut out the circle, and immerse it in water.  Voila!  The plasmid is ready to change bacteria into something new!

The good people at the post office never notice.  The only snags are undergrads – a sophomore who was working with us happened to open the mail.  Our advisor asked later, “Where is that plasmid?  It was being sent by the ______ lab.”

“We got a package from them … but it was just an old catalog.  I recycled it.”

Oops.

Pink_Elephants_on_Parade_Blotter_LSD_DumboAs it happens, numerous psychoactive chemicals can wig out a human brain at concentrations low enough to dissolve on paper.  Somebody sends a saturated sheet through the mail – you cut it out and, instead of using it to transform bacteria, you get high.

Apparently this works well with suboxone – which can be used either as a treatment for or a substitute for heroin – and the THC analogs marketed as K2, spice, or synthetic marijuana.  LSD has long been sold dissolved on blotter paper with goofy cartoons.

And so the Indiana Department of Corrections recently decided to ban all correspondence to inmates that isn’t handwritten on blue-lined white paper.  No greeting cards, no photocopies, no drawings.

A Chicago-based church sends greeting cards to many prisoners over the holidays.  This May, the entire batch of Easter cards they’d sent to Indiana prisoners were returned with a brief note explaining the new mail policy.  Even now, it’s unclear what the policy actually is.  The only regulations for offender correspondence available from the Indiana Department of Corrections are dated September, 2015.  Even these guidelines are vague, mentioning that all decisions are made on a case-by-case basis.

For the correspondence writing workshop I run, I often send printed materials.  Because these are being mailed on behalf of a non-profit corporation, they are supposed to go through – only private mail is supposed to be axed by the new policy.

Or so we’ve been told.

When our corporation sends letters or packages sometimes they go through, sometimes they do not.  The fate of each letter depends on which guard happens to be working in the mail room when it arrives, obviously.  The policy is sufficiently vague that each enforcer will interpret it differently.

A letter’s fate also seems to depend on the identity of the recipient.  If you receive a package while in prison, I’ve been told, the guards are supposed to open it in front of you, show it to you, and then have to either give it to you or explain why you can’t have it.  But with so many and such vague rules, the guards should always be able to think of a reason to bin it.  I’ve noticed that many of our packages that get returned for flimsy reasons were sent to people with long lists of disciplinary infractions.

The rich get richer.  And those who seem to need love most … get nothing.  If you’re disliked, they can sever you from the world.
