Numbers Pool

There’s a beautiful description over at New Scientist of a hypothetical new form of computing device, a “liquid crystal computer” in which calculations would move “like ripples through the liquid.”

According to researchers Žiga Kos and Jörn Dunkel, calculations would be performed by—and registered as—crystal orientations in the liquid, induced or controlled by electromagnetism: “Electric fields could… be used to manipulate the molecules to perform basic calculations, similar to how simple circuits called logic gates work in an ordinary computer. Calculations on the proposed computer would appear as ripples spreading through the liquid.”

Liquid-supercomputer facilities of the near-future might thus resemble not server farms but aquatic centers, sealed interiors lined with reflecting pools kept in different electromagnetic regimes. Although the air inside is utterly still, you watch as small ripples bounce and roll across the surface of each pool, depths triggered by equations. Thinking machines masked as hydrologic infrastructure. Cisterns and aqueducts. Computational hydrology.

There’s a line by William S. Burroughs that I probably quote too often, but I’m nevertheless reminded of again here. Burroughs once described “a vast mineral consciousness near absolute zero thinking in slow formations of crystal,” but perhaps this new vision is more akin to an oceanic consciousness thinking in slow tides and currents, liquid crystal waves of calculation breaking through the deep.

Briefly, given the prevalence of cauldron imagery in Western myth, there is something almost folkloristic about the idea of liquid technologies such as this—pools that can model the future or offer visions of other worlds.

In fact, it tangentially brings to mind another wild proposal: constructing the “Ultimately Large Telescope” [PDF], a vast spinning cauldron on the moon, reflecting astral light from a facility constructed inside the darkness of a lunar crater.

This hypothetical telescope, Universe Today explains, “would rely on liquids rather than coated glass (making it much cheaper to transport to the Moon). One type of liquid would be arranged in a spinning vat while a second metallic liquid (like mercury, which is reflective) would be positioned on top. The vat would spin continuously to keep the surface of the liquid in the correct parabolic shape to work as a mirror.” A witches’ cauldron on the moon, peering into space.

Home Star

This was all over the news back in October, but I am a sucker for stories like this, in which seeds of cosmic revelation are found hidden inside everyday materials, especially when those materials are architectural in form.

In this case, it was “the imprint of a rare solar storm” that left traces in the rings of trees cut into logs by Vikings and used to build cabins 1,000 years ago on the Atlantic coast of Canada.

The wood grain itself was an archive of solar radiance, a warped record of the heavens: “scientists using a new type of dating technique and taking a long-ago solar storm as their reference point have established that the settlement [known as L’Anse aux Meadows] was occupied in AD 1021—all by examining tree rings.”

While there is obviously more to say about the science behind this discovery—all of which you can read here—what interests me is simply the idea that astral events, cosmic storms, stellar weather, electromagnetic pulses from space, whatever you want to imagine, leave traces all around us. That in the depths of our buildings, in our walls and floors, even in the wooden dowels of mass-produced furniture, there can be evidence of immensely powerful and beautiful things, and I would like to remember to look for that again. It’s been a miserable couple of years.

In any case, just a few weeks before this news broke, Lapham’s Quarterly published a short piece, promoting a new episode of their podcast, with some unexpected relevance here. The following quote is a little ungainly taken out of context, but here you go: “‘Hidden round the back of Albrecht Dürer’s St. Jerome of 1494, one of his first paintings… is this enormous star,’ Philip Hoare writes in Albert and the Whale: Albrecht Dürer and How Art Imagines Our World. ‘You would have seen it only if you knew its secret: the galactic event going on, on the other side. Radiating orange-red rays, careering through the perpetual night. A thing of darkness created in light.’”

Hidden on the backs of famous paintings, in the beams of our attics, in the timbers of ancient homes, are galactic events, black stars, things more interesting than this world, burning, and I suppose depression is what happens when you no longer think it’s possible to find such details. When they become inaccessible to you, or when you believe the world’s supply of revelation has been permanently depleted.

Impact Gardening

“Impact gardening” is the evocative term used to describe surface disturbance—and potential biological effects—caused by the crashing of extraterrestrial objects into planetary bodies.

[Image: The surface of Europa, including “the kind of areas churned by impact gardening.”]

These impacts can “churn” or, in effect, plow the surface, exposing previously buried materials to solar radiation—which, in turn, can break down and even sterilize any life thriving there—but it can also push potential organic matter “downward, where it could mix with the subsurface,” almost like planting seeds, according to a short feature published today by NASA.

“If we hope to find pristine, chemical biosignatures,” planetary researcher Emily Costello explained to NASA, “we will have to look below the zone where impacts have been gardening.”

The Age of Horror

[Image: “Clouds, Sun and Sea” (1952) by Max Ernst, courtesy Phillips.]

There’s an interesting space where early modern, mostly 19th-century earth sciences overlap with armchair conjectures about the origins of human civilization. It’s a mix of pure pseudo-science, science-adjacent speculation, and something more like theology, as writers of the time tried to adjust new geological hypotheses and emerging biological evidence—Charles Lyell, Charles Darwin, etc.—to fit with Biblical creation myths and cosmogonic legends borrowed from other cultures. Was there really a Flood? If humans are separate from the animal kingdom, how did we first arrive or appear on Earth?

It is not those particular questions that interest me—although, if I’m being honest, I will happily stay at the table for hours talking with you about the Black Sea deluge hypothesis or the history of Dogger land, two of the most interesting things I’ve ever read about, and whether or not they might have influenced early human legends of a Flood.

Instead, there are at least two things worth pointing out here. One is that these sorts of people never really went away, they just got jobs at the History Channel.

The other is that impossibly long celestial cycles, ancient astronomical records, the precession of the Earth’s poles, and weird, racist ideas about the “fall of Man” all came together into a series of speculations that seem straight out of H.P. Lovecraft.

Take, for example, Sampson Arnold Mackey and his “Age of Horror.”

[Image: Diagram from The Mythological Astronomy in Three Parts by Sampson Arnold Mackey.]

As Joscelyn Godwin writes in a book called The Theosophical Enlightenment, Mackey—a shoemaker, not an astronomer—was fascinated by “the inclination of the earth’s axis and its changes over long spans of time. Astronomers have known at least since classical times that the Earth’s axis rotates once in about 25,920 years, pointing successively at different stars, of which the current one is Polaris, the North Star. One result of this cycle is the ‘precession of the equinoxes,’ according to which the spring-point of the sun moves around the twelve signs of the zodiac, spending about 2160 years in each sign.”

Of course, the assumption that these signs and stars might somehow influence life on Earth is the point at which astronomy morphs into astrology.

Godwin goes on to explain that—contrary to “most astronomers” of his time—Mackey assumed the Earth’s precession was dramatic and irregular, to the extent that, as Mackey speculated, “the earth’s axis describes not a circle but an alternately expanding and contracting spiral, each turn comprising one cycle of the precession of the equinoxes, and at the same time altering the angle of inclination by four degrees.”

The upshot of this is that, at various points in the history of our planet, Mackey believed that the Earth’s “inclination was much greater, to the point at which it lay in the same plane as the earth’s orbit around the sun.”

This sounds inconsequential, but it would have had huge seasonal and climatic effects. For example, Godwin explains, “At the maximum angle, each hemisphere would be pointed directly at the sun day and night during the summer, and pointed away for weeks on end during the winter. These extremes of light and dark, of heat and cold, would be virtually insupportable for life as we know it. In Mackey’s words, it was an ‘age of horror’ for the planet.”

[Image: Diagram from The Mythological Astronomy in Three Parts by Sampson Arnold Mackey.]

The flipside of this, for Mackey, is that the Earth would have gone back and forth, over titanic gulfs of time, between two angular extremes. Specifically, his model required an opposite extreme of planetary rotation in which “there would be no seasons on earth, but a perpetual spring and a ‘golden age.’ Then the cycle would begin again.”

None of this would have been recent: “Mackey dates the Age of Horror at 425,000 years in the past, the Golden Age about a million years ago, and its recurrence 150,000 years from now.”

Nevertheless, Godwin writes, “It was essential to [Mackey’s] system of mythography that the Age of Horror should have been witnessed and survived by a few human beings, its dreadful memory passing into the mythology of every land.”

For Mackey, the implications of this wobble—this dramatic precession between a Golden Age and an Age of Horror, between the darkness of Hell and the sunlight of Paradise—would have been highly significant for the evolution of human civilization.

In other words, either we are coming out of an age of eternal winter and emerging slowly, every minute of the day, every year of the century, into a time of endless sunlight and terrestrial calm, or we are inevitably falling, tipping, losing our planetary balance as we pass into near-permanent night, a frozen Hell of ruined continents and dead seas buried beneath plates of ice.

[Image: The August 2017 total eclipse of the sun, via NASA.]

One of the weirder aspects of all this—something Godwin himself documents in another book, called Arktos—is that these sorts of ideas eventually informed, among other things, Nazi political ideology and even some of today’s reactionary alt-right.

The idea that there was once a Hyperborean super-civilization, a lost Aryan race once at home in the Arctic north, lives on. It’s what we might call the cult of the fallen Northener.

[Image: “Cairn in Snow” (1807) by Caspar David Friedrich.]

What actually interests me here, though, is the suggestion that planetary mega-cycles far too long for any individual human life to experience might be slowly influencing our myths, our cultures, our consciousness (such as it is).

My point is not to suggest that this is somehow true—to say that astrologers and precession-truthers are right—but simply to say that this is a fascinating idea and it has within it nearly limitless potential for new films, novels, and myths, stories where entirely different ways of thinking emerge on planets with extreme seasonal inclinations or unusual polar relationships to the stars.

[Image: From Pitch Black, via Supernova Condensate.]

Think of the only good scene in an otherwise bad movie, 2000’s Pitch Black, where the survivors of a crash on a remote human planetary outpost discover an orrery—a model of the planet they’re standing on—inside an abandoned building.

Playing with the model, the survivors realize that the world they’ve just crashed on is about to be eclipsed by a nearby super-planet, plunging them into a night that will last several months (or weeks or years—I saw the film 20 years ago and don’t remember).

Just imagine the sorts of horrors this might inspire—an entire planet going dark perhaps for centuries, doomed by its passage through space.

In any case, the idea that the earliest human beings lived through something like this hundreds of thousands of years ago—an imminent night, a looming darkness, an Age of Horror that imprinted itself upon the human imagination with effects lasting to this day—would mean that what we think of as human psychology is just an angular epiphenomenon of planetary tilt. Call it orbital determinism.

(Very vaguely related: a planet without a sun.)

Tone Fields Larger Than Stars

[Image: From “Probing Cosmic-Ray Transport with Radio Synchrotron Harps in the Galactic Center,” by Timon Thomas, Christoph Pfrommer, and Torsten Enßlin.]

The above image, as described by Susanna Kohler over at AAS Nova, depicts an ultra-large-scale magnetic “harp” near the center of our galaxy, emitting radio waves. The black lines apparently “span several light-years.”

As Kohler writes, where the parenthetical comments are her own, “a team of scientists argues that this cosmic music is caused by a massive star or a pulsar (a magnetized neutron star) plunging through an ordered magnetic field in the galactic center. As the star crosses (moving upward, in the image above) bundles of field lines, it discharges high-energy cosmic rays that travel in either direction along the bundles, emitting radio waves.”

It’s a kind of cosmic the re min—an instrument where the “musician controls volume and pitch using her hands to interfere with electromagnetic fields generated by the device”—a huge and ancient instrument playing itself in space.

Dimming to Explode

[Image: Betelgeuse, before dimming; photo by ESO, M. Montargès et al, via NASA.]

There are many interesting things about the dimming of Betelgeuse, a giant star in the constellation of Orion’s belt—perhaps a sign that the star is on the verge of exploding in a giant supernova—including the fact that I remember talking about this very scenario in a poetry workshop more than two decades ago. Here we are, still waiting for that light.

[Image: Betelgeuse, during dimming; photo by ESO, M. Montargès et al, via NASA.]

Betelgeuse, of course, is more than 700 lightyears from Earth, which means that it could very well have exploded centuries ago—it could, technically speaking, not even be there anymore, and wasn’t there for your parents or their parents—but the light from that catastrophe simply hasn’t reached Earth. We are always out of synch with the stars we think we’re seeing, unwitting recipients of dead news from above.

Delayed explosions, stars that are no longer there, constellations made of ghosts: the death–or not—of Betelgeuse is the metaphor that gives on giving, as evidenced by the fact that, even in my own lifetime, the topic has come up once again.

But what’s also so interesting about this sort of news is its juxtaposition between human timescales and astral ones, or human awareness colliding with cosmic time more generally: the implication that the universe is capable of extraordinary events that, in the long-term scheme of things, are actually extraordinarily common, but, from within the limits of a human lifetime, even the lifetime of an entire animal species, appear so rare as perhaps never to be encountered. To never be witnessed or even thought possible. There are things that happen only every 100 million years, every billion years, yet here we are right in the middle of it, unaware of strange gravitational inversions or churning, stroboscopic tides of light, of impossible stars and energy forms stranger than all mythology. Black chemistries in space, awaiting catalysis.

There could be physical processes as regular as clockwork pinging off like fireworks—constant, dead rhythms pulsing through the cosmos every two billion years—but our species will never see, hear, or know, because we simply never overlap.

We inhabit the same universe but not the same time.

A friend just sent me a screengrab of his Twitter feed with this great but unplanned juxtaposition, its implied narrative like something out of Watchmen, a human brain transformed into a spherical crystal the size of the sun.

Strange Precipitation

It’s not only snow falling from the sky this winter, but microplastics, a holiday season marked by petrochemical drifts accumulating on our windowsills and roadsides.

European researchers have found much more than just plastics, in fact, snowing down on our shoulders: “Acrylates/polyurethanes/varnish/lacquer (hereafter varnish) occurred most frequently (17 samples), followed by nitrile rubber (16 samples), polyethylene (PE), polyamide, and rubber type 3 (13; ethylene-propylenediene rubber).”

That’s plastic, rubber, varnish, lacquer, and polyethylene—a true precipitation of the Anthropocene—snowing from the sky, as if we’ve embalmed the weather. Zombie snow.

Meanwhile, it seems as if snow itself is being redefined by these studies. For example, every winter, terrestrial landscapes are buried not just by crystals of frozen water, but by the remains of dead stars.

In what would read like a poem in any other context, ScienceNews reports that “exploding stars scattered traces of iron over Antarctic snow.” In other words, metallic fragments of dead stars can be found sprayed across ice at the bottom of our world.

This has cosmic implications:

The result could help scientists better understand humankind’s place in space. The solar system resides within a low-density pocket of gas, known as the local bubble. It’s thought that exploding supernovas created shock waves that blasted out that bubble. But the solar system currently sits inside a denser region within that bubble, known as the Local Interstellar Cloud. The detection of recently deposited iron-60 suggests that this cloud may also have been sculpted by supernovas, the researchers say.

Sculpted by supernovas. We exist within that space, once carved by the detonations of stars whose metallic remains snow down onto dead continents, forming drifts—someday, entire glaciers—of plastic, rubber, polyethylene, and more.

Wandering Cliffs

[Image: ESA/Rosetta/MPS, via New Scientist].

Bringing to mind the landscape paintings of Peder Balke—or maybe Hokusai is more appropriate—entire cliffs seem to “wander” across the surface of Comet 67P.

“The hills may not be alive, but they are moving,” New Scientist reports. “The comet 67P/Churyumov-Gerasimenko has small cliffs that migrate across the landscape for months at a time,” apparently moving toward—not away from—the sun “at a rate of between 3 and 7 centimetres an hour.”

“The cliffs, or scarps, in question are only between 1 and 2 metres tall,” we read, “but on a comet the size of 67P, which is just 4 kilometres across at its longest point, they aren’t negligible—cliffs of a similar scale on Earth would be about 3 kilometres high.”

Frozen waves of geology, marching toward the sun in space.

Imagine a novel about a landscape photographer sent to record such sights, and the things she sees, the weird remoteness of it all, the camp sites and technical difficulties, where exposure time and depth-of-focus becomes an interplanetary concern, the ground pulsing continuously beneath her feet in a slow tide, a creeping sludge, that will never reach completion.

International House of Wobbling

[Image: The Gaithersburg Latitude Observatory, via the U.S. Library of Congress].

The Gaithersburg Latitude Observatory was designed in 1899 as part of a ring of similar facilities around the world, all constructed at the same latitude.

[Images: The Gaithersburg Latitude Observatory, via the U.S. Library of Congress].

Each building was installed at its specific location in order to collaborate in watching a particular star, and—as revealed by any inconsistencies of measurement—to find evidence of the Earth’s “wobble.” This was part of the so-called “International Latitude Service.”

[Image: The Gaithersburg Latitude Observatory, via the U.S. Library of Congress].

The building seen here basically operated like a machine, with a sliding-panel roof controlled by a rope and pulley, and a solid concrete foundation, isolated from the building itself, on which stood a high-power telescope.

[Image: The Gaithersburg Latitude Observatory, via the U.S. Library of Congress].

This pillar gives the building a vaguely gyroscopic feel, or perhaps something more like the spindle of a hard drive: a central axis that grounds the building and allows it to perform its celestial mission.

[Image: The Gaithersburg Latitude Observatory, via the U.S. Library of Congress].

What’s interesting, however, is that this absolutely heroic building program—a structure for measuring heavenly discrepancies and, thus, the wobble of the Earth—is hidden inside such an unremarkable, everyday appearance.

[Image: A photo of the Gaithersburg Latitude Observatory, via NOAA].

It’s a kind of normcore beach hut that wouldn’t be out of place on Cape Cod, with one eye fixed on the stars, a geodetic device revealing our planet’s wobbly imperfections, masquerading as vernacular architecture.

Dark Matter Mineralogy and Future Computers of Induced Crystal Flaws

[Image: Mexico’s “Cave of the Crystals,” via Wikipedia].

I guess I’ve got minerals on the brain.

Anyway, there was an amazing story last week suggesting that, deep inside the planet, minerals might exhibit flaws associated with “collisions with dark matter.” In a sense, this would make the entire interior of the earth a de facto dark matter detector—or, according to researchers at the University of Michigan, “minerals such as halite (sodium chloride) and zabuyelite (lithium carbonate), can act as ready-made detectors.”

Proving this hypothesis sounds like the opening scene of a blockbuster science fiction film: “An experiment could extract the minerals—which can be around 500 million years old—from kilometres-deep boreholes that already exist for geological research and oil prospecting. Physicists would need to crack open the extracted minerals and scan the exposed surfaces under an electron or atomic force microscope for the tracks made by recoiling nuclei. They could also use X-ray or ultraviolet 3D scanners to study bigger chunks of minerals faster, but with lower resolution.”

Either way, it’s incredible to imagine that slightly altered mineral structures deep inside the planet might reveal the presence of dark matter washing through the cosmos. After all, the Earth is allegedly “constantly crashing through huge walls of dark matter,” so the idea that some rocks might be glitched and scratched by these impacts isn’t that hard to believe. In fact, this brings to mind another hypothesis, that the GPS satellite network is, in fact, a huge, accidental dark matter detector.
