The Mystery of Jupiter's Shrinking Great Red Spot Might Be Solved





Is it possible that a large gas giant having sufficient spin will generate such a phenomena?  my alternative is a spin mass ejection, but that should also collapse.

so far we do not see it elsewhere, but size and spin must matter.  And having the gas component rotating on its side also conforms to dynamics as well.

i do like this argument best.

The Mystery of Jupiter's Shrinking Great Red Spot Might Be Solved



27 July 2024

It's the iris in the great eyeball of Jupiter, revolving to gaze balefully out upon the cosmos: the Great Red Spot, the single largest, longest-lived storm in the entire Solar System.


Humanity has been observing it for centuries, a colossal anticyclone currently a little bit larger than Earth, with winds that howl around in an anticlockwise direction at up to 680 kilometers (425 miles) per hour.


As mighty as it rages, however, the Great Red Spot has significantly diminished since the first definite records of its existence in 1831. The storm was once much larger; over time, it has dwindled, and it dwindles still.


Scientists now think they understand why: The Great Red Spot feeds off of other, smaller storms merging into it. If there aren't those smaller storms for the Great Red Spot to devour and subsume, it will be unable to maintain its prodigious dimensions.


"Many people have looked at the Great Red Spot over the last 200 years and were as fascinated by it as I am," says astronomy PhD Caleb Keaveney of Yale University.


"We found through numerical simulations that by feeding the Great Red Spot a diet of smaller storms, as has been known to occur on Jupiter, we could modulate its size."


Once, back in the late 19th century, the Great Red Spot spanned a whopping 39,000 kilometers across. Now, it's just over a third of that width at 14,000 kilometers. Earth's 12,742-kilometer diameter could still fit inside – but it's getting to be a tighter squeeze. We've never seen the Spot so (relatively) small.


Scientists have been investigating this strange phenomenon, but it's a puzzler. Jupiter is very different from Earth, and its weather much wilder. In spite of these differences, though, fluids – such as atmospheric gasses – behave in certain ways that can be explored using the mathematics of fluid dynamics.


And, while we can't extrapolate 1:1 the behavior of Earth's weather onto Jupiter, we can use our understanding of Earth's atmospheric processes to try to figure out what is happening on Jupiter. This is what Keaveney and his colleagues have done.


We know, from research published in 2021, that Jupiter's Great Red Spot effectively 'eats' smaller storms it encounters, growing larger in the process. So, the researchers used a similar phenomenon observed here on Earth to inform their models of Jupiter's atmosphere.


In the jet streams that circulate through Earth's atmosphere, long-lived, high-pressure systems called heat domes, or blocks, can form, where the jet stream slows to a halt. These blocks can play a significant role in heat waves and droughts as they trap warm temperatures below them for long periods.


The longevity of these blocks has been linked to anticyclones and other smaller weather phenomena. Equipped with this information, the researchers created a model for Jupiter's atmosphere and the Great Red Spot, simulating interactions between the storms.


They found that, when a smaller storm encountered the Great Red Spot, the former storm would maintain its size, or grow, compared to simulations without these interactions. And the degree to which the Spot was sustained was stronger if there were more interactions. Finally, the strength of the smaller storm played a role, too. A stronger storm gave the Great Red Spot a bigger boost.


There's nothing we can really do about the Great Red Spot. Jupiter is going to Jupe, we're just here to enjoy the show. But learning about its amazing atmosphere can help us better understand the way weather works on our own planet, which is pretty neat.


"Our study has compelling implications for weather events on Earth," Keaveney says.


"Interactions with nearby weather systems have been shown to sustain and amplify heat domes, which motivated our hypothesis that similar interactions on Jupiter could sustain the Great Red Spot. In validating that hypothesis, we provide additional support to this understanding of heat domes on Earth."

The research has been published in Icarus.

How likely is it that WWI would have started without the assassination of Franz Ferdinand?






So just why is this not part of the historical narrative and why have i never heard of it?  The hard evidence cited is defensive positioning long ahead of hostilities.  Rather cautionary rather than indicative of a plan.

every allied apologist since and during WWI has been trying to affix blame on Germany.  If this were actually real, it would have been shouted from the rooftops.

Germany had no national interest except defense from famously hostile neighbors.  We were a long ways from ideas of peaceful coexistence of today.

The French had every interest in putting this tale about and likely falsified it all because they could..

If it has not been subjected to historical research, then it is because it is a known fraud.  just saying.

How likely is it that WWI would have started without the assassination of Franz Ferdinand?

100% certain.

The German overall war plan, confiscated by the French in 1919 literally stated that war should start no later than September 1914.

Germany’s war preparations such as moving troops to the Belgian border and storing extra ammunition on the Franco-Belgian and Russian borders began months before the assassination.

The Imperial German Army of 1914 was far better prepared for a winter war than the Russians.

France was to be defeated in exactly 42 days after which the troops would have been moved to the East to take on Russia.

With a war starting in September 1914 (at the latest), the solid frozen ground would facilitate German movements by the tie they had moved their troops to the Eastern Front.

It was hoped to being Russia to its knees by late 1914 or early 1915 which would have given the Germans a couple of months to consolidate their positions and bring forward extra supplies before the thaw would turn Russia into one big mud bath.

So we know for a fact that Germany would have gone to war in 1914. The assassination was just a convenient excuse. if this hadn’t taken place, the Germans would have found another excuse or faked an incident.

This war plan is one of the reasons why France wanted to include the famous “guilt clause” in the Versailles Treaty.

Alas, these documents and the impounded diplomatic correspondence are generally unknown to the public. They were impounded by the French in 1919 an published i three leather-bound volumes in 1921. By then, general interest in the war had completely faded.

The Ancestral Myth of the Hollow Earth and Underground Civilizations







this is a decent history of the hollow earth narrative and surrounding artwork.

First though understand that if the only physics available is Newtonian. then the whole concept is just impossible.  all that assumes that all objects are formed by concretation.

My cloud cosmology assumes instead that all large objects in the universe are formed by an act of creation that opens a void in the Dark Matter and then triggers an act of creation to then produce new matter while pushing out the edge of the void with radiation.  Obviously this generates a bubble of matter around an inner sun.  Now this model applies to all visible objects including the sun and all the planets.  this implies that consciousness can move radiation to produce a void.

If this model is real, then away we go.  We do have ample conforming evidence supporting it all.  This means that if A is true than B must follow.  This also holds for the tilting of the shell 15 degrees south 1900 BP.

understand that TILT! eliminates the northern Ice Age the only way it would work.  and the movement sent the Inner Sea onto the Earths surface out of the DEEP to produce the great Flood.  just saying.

All This means that we cannot void the hollow Earth Meme. ( it should be easy peasy )  however the TILT surely produced closure events as well and do not forget that plenty of rock is plastic over geological time scales.  In the event, i am forced to keep an open mind.
 

The Ancestral Myth of the Hollow Earth and Underground Civilizations


ANCIENT ORIGINS UNLEASHED

Countless stories, myths, and legends are told about underground cities and subterranean civilizations spread through a vast network of interconnected tunnels across the planet.

There are many rumors surrounding these underground portals. We have only to remember the mysterious stories that revolve around the tunnels and galleries of the Cueva de los Tayos in Ecuador, or stories about entrances to underground worlds, supposedly located in the Andes, the Himalayas, the Gobi Desert, Turkey, and even below the Sphinx of Giza.
The Hollow Earth Theory and an Expedition to the Arctic

The Hollow Earth theory states that the Earth is a hollow planet with ancient entrances to the subterranean world scattered throughout it, including near both polar caps. This theory has been reported since ancient times and scientists such as Edmund Halley have defended it throughout history.



From 1818-1826, the American John C. Symmes passionately supported the theory as well. According to him, there was a subterranean world inside our planet illuminated by a tiny sun, and that included mountains, forests, and lakes. Symmes launched a national campaign aiming to raise the necessary funds to send an expedition to the Arctic to search for an entrance to the subterranean world. He even sent a proposal to the United States Congress, with the intention of getting government assistance to find the entrance to the inner world. 

Unfortunately for him, he died before the government did allocate funding for his purpose and the expedition departed in 1838, although, in truth, its goals were not so altruistic. In reality it was part of the ploy as world powers were trying to learn the importance of the only land not yet conquered the world: both polar caps. Regardless, commanded by Charles Wilkes, the expedition lasted four years. It served to discover the vast geographical extent of the Arctic, but no sign of a passage into the earth was found.

Nonetheless, the idea of Symmes remained anchored in the minds of a handful of writers (who tend to love the search for attainment of seemingly impossible dreams.) Thus, Edgar Allan Poe, Jules Verne, and HP Lovecraft, among many others, paid tribute to the fascinating theory of the Hollow Earth.

Interest in the Hollow Earth theory did not end there. In fact, in the twentieth century, with a knowledge of geography and geology of the Earth, that was still lacking, there were those who continued trying to access that mysterious world under the earth’s crust. For example, some of the Nazi leaders, the lovers of ancient myths and the occult in Germany, showed a marked interest in these types of theories.
History of Hollow Earth Theory

Edmund Halley (1656 - 1742), the English scientist who studied the comet that bears his name, may have been the first to develop a scientific hypothesis about the Hollow Earth. After a series of observations of the Earth's magnetic field, Halley concluded that the anomalies observed could only be explained if the Earth was composed of two spheres: an external solid one and an internal hollow one, each with its own magnetic axis.

Later on, another American, Cyrus Teed, became convinced that it is mathematically impossible to discern whether we are inside or outside of a sphere, so we could live inside a hollow universe. In the center it would be the Sun, with the planets and stars only appearing bright to us because they reflect sunlight on the surface of the concave Earth. This land was called  Koresh - which is the Hebrew translation of his own name, Cyrus. Teed even founded a church and its adherents remained active and defending these ideas until at least 1982.

With the dawn of the twentieth century other scholars, such as William Reed and Marshall Gardner, also believed they could provide evidence of the existence of an inner world. One of the most curious facts wielded as an argument, made ​​by some Arctic explorers, was that air and water temperatures warmed as they approached the North Pole. Based on these and other observations, they also claimed that mammoths were not extinct, but still inhabiting the interior of the Earth.


As previously mentioned, there were Nazi leaders who supported the hollow earth theory. Adolf Hitler also believed in the hollow earth theory, but for him it provided the location where the “pure” and “perfect” Aryans who he thought dominated the world would meet. What is more, the German Thule Society - the main esoteric circle of the time, held a very close hypothesis, although theirs was related to the myths of lost underground kingdoms of Agartha and Shambhala.



Adolf Hitler and several of his colleagues firmly believed in the Hollow Earth Theory. (National Archives and Records Administration/Public domain)

Meanwhile, the first man to fly over the poles, Richard E. Byrd, in his report said he “inspected about 26,000 km (16,155.7 miles) around and beyond the Pole.” This simple sentence with the words " beyond the Pole" are the foundation on which many advocates of the hollow earth theory accuse the US government (who funded Byrd’s flight) of a cover-up, saying that Byrd went into the Inner Earth.

Shambhala Myths and Agartha

Myths are as old as humanity itself, so are the myths of beings that inhabit the depths of the Earth. In contrast to the angels of heaven, tradition generally sent demons underground. A clear example is the Christian hell. 

In contrast, Central Asian Buddhists believe in the wonderful land under our feet which is known as Agartha (or Agartta). Agartha is supposedly a place where beings are more beautiful and much wiser than we are and which has a king that has the power to read the human soul.

For thousands of years Tibetan scholars, besides teaching about an inner world, say they are in contact with this "King of the Inner World" or supreme ruler for the entire planet, for whom the Dalai Lama is a representative for the outside world. They also speak and write about tunnels that connect Tibet with the inner world (which they protect), saying that there are many others scattered across the Earth, such as those found under the great pyramids of Egypt and South America. Entrances to subterranean cities also are said to exist around the vast Amazon Basin, for example connecting the lost city of  "El Dorado"  with the rest of the ancient world.


The capital of this inner world - and therefore of the whole world is said to be a city called Shambhala where the King of the World resides and his court of advanced beings teach some of humanity about science, art, religion, and philosophy.



According to ancient Tibetan myths, pyramids of Central and South America (pictured, Tikal in Guatemala) are settled on vast networks of underground tunnels, connecting the ancient cities with the sacred kingdom they refer to as Agartha. (chensiyuan/CC BY-SA 4.0)

The Shambhala Tibetan headquarters of the "spiritual government of humanity," may be located in the vicinity of Balkh, a former Afghan settlement known as  "the mother of cities"  according to the prestigious scholar on Tibet, Alexandra David-Neel. The folk traditions of Afghanistan say that after the Muslim conquest, Balkh was called   Shams-i-Bala (Candle High)  which seems a transformation from the Sanskrit Shambhala into Persian. 

Shards from famed astronomer's garden show secret alchemy lab details




this confirms that European alchemists were following the path of Chinese alchemist from 2000 years before.  actually a good starting point.  what they had learned to do was to run a process that recovered or consumed what were obvious elements.

So far so good and the list here is actually as good as it gets. they could take certain elements into and out of combination.  Their practice was to do this many times in an effort to change state, whatever that could mean.  This can be dangerous.

the tungsten is very interesting because elemental tungsten actually looks and weighs about the same as gold.  Tells you were the stories came from

Shards from famed astronomer's garden show secret alchemy lab details

July 25, 2024


Alchemists have become most famous for trying to turn lead to gold, but they also created medicinal potions, especially for the wealthy class


Tycho Brahe is best known as a Danish Renaissance astronomer. But he was also a bit of an alchemist, and a first-ever analysis on shards found at his former home from the 1500s has shed some light on just what he was up to in his basement lab.


During his life in the late 16th century, Brahe lived on the Danish island of Ven in a combined residence and observatory known as Uraniborg. The entire complex was demolished after his death in 1601, and the rubble was scattered throughout the land to be reused in other buildings. So little was left behind that could help modern day researchers reconstruct the scientist's life.

While it was known that Brahe dabbled in alchemy, and that he delivered medicines to the elite European classes during the Renaissance – allegedly including a plague remedy to his patron, Emperor Rudolph II – such practices were kept close to the vest. After all, if you had been able to turn lead into gold or create an immortality elixir, why would you share the deets? As a result, no particulars of his alchemical work survived.

In the late 1980s though, an excavation was carried out on the grounds of Uraniborg that uncovered glass and pottery shards believed to have come from Brahe's lab. Now, four of the glass shards and one pottery shard have been chemically analyzed for the first time by Kaare Lund Rasmussen from the University of Southern Denmark where he is Professor Emeritus and expert in archaeometry. In carrying out the work, Rasmussen used two popular imaging techniques: Laser Ablation Inductively Coupled Plasma with Mass Spectrometry.


Among a host of chemicals found, the study revealed the presence of nine that were specially enriched, which means Brahe would have been working to concentrate or refine them in some way: mercury, lead, copper, tin, antimony, nickel, zinc, copper and most intriguing of all, tungsten.
Transmuting Wolfram?

The tungsten raised some eyebrows because at the time of Brahe's work, the element hadn't ever been described. In fact, it wouldn't get isolated and described until Swedish Chemist Carl Wilhelm Scheele sorted it out nearly 200 years later. The most likely possibility is that the tungsten came into Brahe's lab bound to some other mineral and when the alchemist got busy refining that substance, the tungsten got enriched as well.


But in the early 1500s, a German mineralogist had written about difficulty smelting tin due to the presence of some other material. That material, which the scientist called Wolfram, meaning wolf's froth, would eventually come to be known as tungsten and Brahe might have been aware of it and interested in using it for the potions he was brewing in his lab.
The Moon, silver, and the brain



The other enriched elements on the shards track with known alchemical processes at the time. In particular, copper, antimony, gold, and mercury were part of three medicines invented by Swiss alchemist Paracelsus collectively known as Medicamenta tria, for which Brahe became famous. In fact, previous analysis carried out by Rasmussen showed that Brahe's hair and bones had sufficient levels of gold to indicate that he was likely taking his own remedies.

"It may seem strange that Tycho Brahe was involved in both astronomy and alchemy, but when one understands his worldview, it makes sense," said Poul Grinder-Hansen. Hansen is the curator of Denmark's National Museum and he worked with Rasmussen to place the chemical analysis into a historical context.

"He believed that there were obvious connections between the heavenly bodies, earthly substances, and the body's organs," he continued. "Thus, the Sun, gold, and the heart were connected, and the same applied to the Moon, silver, and the brain; Jupiter, tin, and the liver; Venus, copper, and the kidneys; Saturn, lead, and the spleen; Mars, iron, and the gallbladder; and Mercury, mercury, and the lungs. Minerals and gemstones could also be linked to this system, so emeralds, for example, belonged to Mercury."

Hansen and Rasmussen's work has been published this week in the journal Heritage Science.

Universe’s missing matter may be explained by galaxies leaking gas



Imagine the galactic core is an engine for collecting matter, running that matter into an event horizon and converting it into complex photonic energy allowing it to leave the galaxy at light speed.

then imagine these photon complexes decay back to matter on the way even past the galactic rim.  all this should look like a spiral stream of matter.  We would find plenty of matter outside the apparent rim and gravity would be collecting it all along with massive plasmas.

We must stop thinking all this matter we see is reflecting a Newtonian rule.  any ejected matter will be slow and slower and never in a straight line.  Anything straight is photon decay.  And then suppose complex photons decay quickly and never really reach us.


Universe’s missing matter may be explained by galaxies leaking gas

The gas that surrounds galaxies appears to be more spread out than previously thought – and this could help solve a mystery over missing matter



23 July 2024





Galaxies like Andromeda have a supermassive black hole at the centre

NASA/JPL-Caltech



Supermassive black holes appear to be more powerful than our theories suggest, blasting the gas that surrounds galaxies much further away than expected. This finding could help explain several cosmological conundrums, including the fact that the universe seems to be missing large amounts of gas.

Most objects that we can measure in the universe, like stars and galaxies, emit light that we can observe from Earth. But measuring cold or spread-out gas, which is crucial for our understanding of how the universe works, is trickier because it often doesn’t give off as much light.


A new method that astronomers have developed to map this gas makes use of the cosmic microwave background (CMB), which is the leftover light from the big bang. This light has been travelling through the universe for billions of years, and any object it has encountered along the way, such as galaxies and their gas, leaves a detectable imprint on it that can be measured. “It’s as if the galaxies are casting shadows on the CMB map,” says Boryana Hadzhiyska at the University of California, Berkeley. But because these shadows are very faint, you need many millions of galaxies to get a clear signal, she says.

Now, Hadzhiyska and her colleagues have measured these shadows in the highest detail yet and found that the gas causing them appears to be much more spread out than we find in our best simulations of the universe. “It’s finding something that we don’t really expect, which is that the gas is way more extended than, for example, galaxy formation models predict,” says Hadzhiyska.

To measure these shadows, she and her team combined one of the most detailed maps of the CMB, made using the Atacama Cosmology Telescope (ACT) in Chile, with a vast catalogue of relatively nearby galaxies mapped out by the Dark Energy Spectroscopic Instrument (DESI) in Arizona. By measuring how distorted the CMB map was in relation to the galaxies, they could find the average density of space, which told them where the galaxies’ gas was distributed.


While typical simulations of the universe assume that the gas only extends 10 to 20 per cent outside of a galaxy’s outer limit, Hadzhiyska and her team found that it could stretch out as far as two to three times the galaxy’s radius. This is probably due to phenomena associated with supermassive black holes, such as their jets, being more powerful than we thought, though we don’t know the exact mechanisms at play, says Hadzhiyska.

This finding confirms earlier work that found hints of the spread-out gas using the same technique, says Leah Bigwood at the University of Cambridge, but the increased sensitivity boosts astronomers’ confidence that it is real. “It’s providing this evidence that maybe we’re underestimating at the moment how much these supermassive black holes can push matter out, and if we are underestimating that it can mean it would be biasing our cosmology.”

One problem this could help solve is the so-called missing baryon problem. The CMB can be used to estimate how much baryonic matter – that is, ordinary rather than dark matter – there is in today’s universe. But the amount of matter we can observe with light-based telescopes is much less than predicted.

This missing matter might just be gas spread out beyond where we can see it, says team member Simone Ferraro, who is also at the University of California, Berkeley. “None of the gas has disappeared, it’s just been pushed out way beyond where people could see before. Now we have these new techniques, and this new data, we’re able to see that far out,” he says.

It could also help to resolve a disagreement between two ways of measuring how clumpy the universe is. The first uses the CMB and the standard model of cosmology to work out how spread out the universe is now, which gives a higher result than another technique measuring how much the gravity of galaxies bends light. However, if the CMB calculation is rerun using the new gas distribution data, then the tension between the two measurements appears to go away, says Hadzhiyska. However, a more detailed analysis will be needed to prove it, she says.

The Physics of Cold Water May Have Jump-Started Complex Life




We needed this, because the assumption of room temperature chemistry accepts a huge level of disorder, while cold literally forces order.  this also makes H3O3 way more stable as well.

All of a sudden we have a life forming environment that may work far deeper than imagined as yet.

Can cold molecules self form to make decision gates and perhaps processors.  We do not think so, but suppose it is easy and then the joke is on us.  We need to really investigate this.  It merely made life inevitable?


The Physics of Cold Water May Have Jump-Started Complex Life

When seawater gets cold, it gets viscous. This fact could explain how single-celled ocean creatures became multicellular when the planet was frozen during “Snowball Earth,” according to experiments.



Frigid temperatures hundreds of millions of years ago, during ancient periods known as Snowball Earth, may have created the conditions for complex multicellular life to evolve. New experiments show how.

Introduction


Once upon a time, long ago, the world was encased in ice. That’s the tale told by sedimentary rock in the tropics, many geologists believe. Hundreds of millions of years ago, glaciers and sea ice covered the globe. The most extreme scenarios suggest a layer of ice several meters thick even at the equator.

This event has been called “Snowball Earth,” and you’d think it would be a terrible time to be alive — and maybe, for some organisms, it was. However, in a warmer period between glaciations, the first evidence of multicellular animals appears, according to some interpretations of the geological record. Life had taken a leap. How could the seeming desolation of a Snowball Earth line up with this burst of biological innovation?

A series of papers from the lab of Carl Simpson proposes an answer linked to a fundamental physical fact: As seawater gets colder, it gets more viscous, and therefore more difficult for very small organisms to navigate. Imagine swimming through honey rather than water. If microscopic organisms struggled to get enough food to survive under these conditions, as Simpson’s modeling work has implied, they would be placed under pressure to change — perhaps by developing ways to hang on to each other, form larger groups, and move through the water with greater force. Maybe some of these changes contributed to the beginning of multicellular animal life.

To test the idea, Simpson, a paleobiologist at the University of Colorado, Boulder, and his team conducted an experiment designed to see what a modern single-celled organism does when confronted with higher viscosity. Over the course of a month, he and his graduate student Andrea Halling watched how a type of green algae — members of a lab-friendly species that swims with a tail-like flagellum — formed larger, more coordinated groups as they encountered thicker gel. The algae collectively motored through the fluid to keep up their feeding pace. And, intriguingly, the groups of cells remained stuck together for 100 generations after the experiment ended.

The research offers a novel take on the emergence of multicellular life, said Phoebe Cohen, a paleontologist at Williams College who has spoken with Simpson about his idea over the years but was otherwise uninvolved with the work. The field is overflowing with papers about triggers for the evolution of animal multicellularity that draw on geochemical measurements, she said, but few consider the biology of individual organisms.



To re-create Snowball Earth conditions in the lab, biologists placed swimming algal cells into gel of varying viscosity. The cells that made it to the thickest, outer layer displayed signs of collective behavior — a potential step toward multicellularity.


Andrea Halling


Introduction


“I’m very charmed by the idea, by the experimental setup as well,” Cohen said. “It’s really wonderful to see work saying: What’s actually going on here? How are these early organisms actually experiencing their environment?”

The experiment comes with a few caveats, and the paper has yet to be peer-reviewed; Simpson posted a preprint on biorxiv.org earlier this year. But it suggests that if Snowball Earth did act as a trigger for the evolution of complex life, it might be due to the physics of cold water.
A Frozen Paradox

“Snowball Earth” was on everyone’s lips when Simpson was an undergraduate in the late 1990s. In 1992, the geochemist Joseph Kirschvink had pointed out that there was good geological evidence for a global glaciation event in the ancient past; crucially, he provided a model for how all that ice might have been coerced to melt again. Then, in 1998, the Harvard geologist Paul Hoffman and colleagues published a landmark paper that applied these ideas to observations of sedimentary deposits in Namibia. They agreed: The rocks indicated the presence of glaciers in the warmest parts of the world around 700 million years ago.

Even back then, the timing of Snowball Earth troubled Simpson. “That was a total paradox for me,” he said. “There’s no way Snowball Earth was real, given how much interesting evolution was happening at the time.” Before Snowball Earth, fossils are tiny, he said. Afterward, they are big and complicated.

It is difficult to precisely date when animals arose, but an estimate from molecular clocks — which use mutation rates to estimate the passage of time — suggests that the last common ancestor of multicellular animals emerged during the era known as the Sturtian Snowball Earth, sometime between 717 million and 660 million years ago. Large, unmistakably multicellular animals appear in the fossil record tens of millions of years after the Earth melted following another, shorter Snowball Earth period around 635 million years ago.





Mark Belan for Quanta Magazine

The paradox — a planet seemingly hostile to life giving evolution a major push — continued to perplex Simpson throughout his schooling and into his professional life. In 2018, as an assistant professor, he had an insight: As seawater gets colder, it grows thicker. It’s basic physics — the density and viscosity of water molecules rises as the temperature drops. Under the conditions of Snowball Earth, the ocean would have been twice or even four times as viscous as it was before the planet froze over.

Simpson wondered what it would have been like to be a microscopic organism in the ocean during Snowball Earth. Maybe the whole thing wasn’t so paradoxical after all.



It’s basic physics — the density and viscosity of water molecules rises as the temperature drops.

To very small single-celled creatures, thick seawater would have posed some big problems. Bacteria feed by diffusion — the movement of nutrients through water from areas of high concentration to low concentration — and tend to wait for food to come to them. However, at low temperatures, diffusion slows down. Nutrients don’t travel as quickly or as far. For cells, living in a cold and more viscous fluid means getting less to eat. Even very small organisms that can propel themselves, such as cells with flagella, move more slowly in cold water. As a result, they encounter food less frequently.

A bigger organism, on the other hand, can navigate thicker waters without much trouble. A cluster of cells has the benefit of inertia: Their combined mass is large enough to allow them to build up steam and barrel through thicker fluid. “At some point, you are too big for this to matter,” Simpson said.

In 2021, he published his hypothesis that Snowball Earth viscosities would have put a significant strain on organisms’ ability to feed themselves and could have spurred some to evolve multicellularity. Then, with collaborators at the Santa Fe Institute, he designed mathematical models of small creatures — single cells that fed by diffusion and self-propelling cells that fed by moving around — living in thicker and thicker fluids. In the models, posted to biorxiv.org at the end of 2023 and recently published in the peer-reviewed Proceedings of the Royal Society B, the diffusion feeders responded to thicker fluids by shrinking in size. The self-propelling cells, equipped by the equations with the ability to cling together if needed, formed larger and larger multicellular groups. This suggested that if there were already multicellular organisms when Snowball Earth occurred — or at least organisms with the ability to take on multicellular forms — the thicker fluid could have given them a reason to get bigger.



The paleobiologist Carl Simpson has led a body of work — computer modeling and experiments with living organisms — to study whether the physics of cold water causes cells to act collectively like a multicellular creature.

Introduction


The results were intriguing, but they were only computer models. Simpson thought: Well, what if they did this with real organisms?

The geologist Boswell Wing, a colleague at the University of Colorado, Boulder, had a colony of Chlamydomonas reinhardtii in his lab. These algae have twirling flagella that allow them to move under their own power. They are usually unicellular. But they can switch into a multicellular form under certain stressful conditions. Would higher viscosity, like that of the oceans during Snowball Earth, prove to be one of them?

There’s no way for biologists to travel back in time to test the real conditions of Snowball Earth, but they can try to re-create aspects of them in the lab. In an enormous, custom-made petri dish, Halling and Simpson created a bull’s-eye target of agar gel — their own experimental gauntlet of viscosity. At the center, it was the standard viscosity used for growing these algae in the lab. Moving outward, each concentric ring had higher and higher viscosity, finally reaching a medium with four times the standard level. The scientists placed the algae in the middle, turned on a camera, and left them alone for 30 days — enough time for about 70 generations of algae to live, swim around for nutrients and die.




Andrea Halling led experiments with living creatures to see how life might have responded to evolutionary pressures 600 million years ago.

Halling and Simpson suspected that as the algae reproduced and crowded the center circle of normal viscosity, any algal cells that could handle the thicker medium would spread outward. Perhaps those that reached the outermost ring would look and behave differently from those that remained in the center.

Simpson was particularly curious as to whether algae that made it into the highest viscosity ring would find ways to increase their swimming speed. The algae are photosynthetic, so they get energy from the sun. But they need to pick up nutrients such as phosphorus from the environment, so movement is still important to their survival. Maintaining the same level of nutrients in high-viscosity surroundings would require them to find a way to keep up their speed.

After 30 days, the algae in the middle were still unicellular. As the scientists put algae from thicker and thicker rings under the microscope, however, they found larger clumps of cells. The very largest were wads of hundreds. But what interested Simpson the most were mobile clusters of four to 16 cells, arranged so that their flagella were all on the outside. These clusters moved around by coordinating the movement of their flagella, the ones at the back of the cluster holding still, the ones at the front wriggling.

Comparing the speed of these clusters to the single cells in the middle revealed something interesting. “They all swim at the same speed,” Simpson said. By working together as a collective, the algae could preserve their mobility. “I was really pleased,” he said. “With the coarse mathematical framework, there were a few predictions I could make. To actually see it empirically means there’s something to this idea.”

Intriguingly, when the scientists took these little clusters from the high-viscosity gel and put them back at low viscosity, the cells stuck together. They remained this way, in fact, for as long as the scientists continued to watch them, about 100 more generations. Clearly, whatever changes they underwent to survive at high viscosity were hard to reverse, Simpson said — perhaps a move toward evolution rather than a short-term shift.




In gel as viscous as ancient oceans, algal cells began working together. They clumped up and coordinated the movements of their tail-like flagella to swim more quickly. When placed back in normal viscosity, they remained together.

Introduction


Modern-day algae are not early animals. But the fact that these physical pressures forced a unicellular creature into an alternate way of life that was hard to reverse feels quite powerful, Simpson said. He suspects that if scientists explore the idea that when organisms are very small, viscosity dominates their existence, we could learn something about conditions that might have led to the explosion of large forms of life.
A Cell’s Perspective

As large creatures, we don’t think much about the thickness of the fluids around us. It’s not a part of our daily lived experience, and we are so big that viscosity doesn’t impinge on us very much. The ability to move easily — relatively speaking — is something we take for granted. From the time Simpson first realized that such limits on movement could be a monumental obstacle to microscopic life, he hasn’t been able to stop thinking about it. Viscosity may have mattered quite a lot in the origins of complex life, whenever that was.

“[This perspective] allows us to think about the deep-time history of this transition,” Simpson said, “and what was going on in Earth’s history when all the obligately complicated multicellular groups evolved, which is relatively close to each other, we think.”



Viscosity may have mattered quite a lot in the origins of complex life.

Other researchers find Simpson’s ideas quite novel. Before Simpson, no one seems to have thought very much about organisms’ physical experience of being in the ocean during Snowball Earth, said Nick Butterfield of the University of Cambridge, who studies the evolution of early life. He cheerfully noted, however, that “Carl’s idea is fringe.” That’s because the vast majority of theories about Snowball Earth’s influence on the evolution of multicellular animals, plants and algae focus on how levels of oxygen, inferred from isotope levels in rocks, could have tipped the scales in one way or another, he said.

That novelty is a strength, said the geobiologist Jochen Brocks of the Australian National University. However, in his assessment, Simpson’s hypothesis makes a few logical leaps that don’t hold up. It’s not clear that the earliest animals would have been swimming freely in water, Brocks said. Some of the first fossils that can be confidently called “animals” were anchored on the ocean floor.

Perhaps more importantly, the timeline of animal origins is very uncertain. Some estimates suggest that the Snowball Earth period might line up with the last common ancestor of animals. But these are based on molecular inferences from DNA that are hard to confirm, Brocks said. In his opinion, it’s difficult to say how much importance to assign to this era. Butterfield also remarked on this uncertainty: “There’s no evidence of anything getting large until quite a bit after [Snowball Earth].”

That said, Brocks found Simpson’s experiment quite clever and beautiful. The fact that organisms might respond to high viscosity by developing collective behavior deserves to be better understood, he said — whether Snowball Earth led to the evolution of complex animal life or not.

“Putting this into our repertoire of thinking about why these things evolved — that is the value of the entire thing,” he said. “It doesn’t matter if it was Snowball Earth. It doesn’t matter if it happened before or after. Just the idea that it can happen, and happen quickly.”



Brocks is curious about what would happen if a similar experiment were performed with choanoflagellates, little creatures that are more closely related to animals than algae are. They rely entirely on hunting to get food — they can’t photosynthesize — so they would be especially vulnerable to slowdowns caused by high viscosity. If they started to take on multicellular forms under those conditions, that would suggest that Simpson’s results represent a more general truth about how life responds to its environment. “It would be absolutely ultra-exciting,” he said.

Simpson is, in fact, currently working with choanoflagellates. Right now, he is trying to understand how they live.

“They’re really beautiful and complicated creatures,” he said. They can take on many different forms: There are fast swimmers with long flagella, slow swimmers that meander, ones that stick to a surface to grow. “They can grow these little tendrils off the tip and walk around like on stilts; they have sex, and they fuse, and they form chain colonies and rosette colonies … and if you squeeze them, apparently they’ll lose their flagella and turn into an amoeba,” he said. When it comes to responding to the challenges of a radical new environment, he reflected, “they’ve got a lot to work with.”

All that we are





This is important, and not understood or taught at all.  We live best when we learn to live in the future and understand that.  the past can only speak to the mistakes made and also cannot be changed.

Yet today, a billion folks can implement rotational grazing and create a thriving global soil base to support humanity.  It becomes irrelevant that we gat it wrong for 10,000 years.

read this and understand why King was important.  He chose to show a way forward and that road leads back to his philosophy.  We so needed to know this.

I wonder if Mahatma understood this line of thought.


All that we are

The philosophy of personalism inspired Martin Luther King’s dream of a better world. We still need its hopeful ideas today

On 25 March 1965, the planes out of Montgomery, Alabama were delayed. Thousands waited in the terminal, exhausted and impassioned by the march they had undertaken from Selma in demand of equal rights for Black people. Their leader, Martin Luther King, Jr, waited with them. He later reflected upon what he’d witnessed in that airport in Alabama:

As I stood with them and saw white and Negro, nuns and priests, ministers and rabbis, labor organizers, lawyers, doctors, housemaids and shopworkers brimming with vitality and enjoying a rare comradeship, I knew I was seeing a microcosm of the mankind of the future in this moment of luminous and genuine brotherhood.

In the faces of the exhausted marchers, King saw the hope that sustained their hard work against the violence and cruelty that they had faced. It is worth asking: why was King moved to try to create a better world? And what sustained his hope?

A clue can be found in the PhD dissertation he wrote at Boston University Divinity School in 1955:

Only a personal being can be good … Goodness in the true sense of the word is an attribute of personality.

The same is true of love. Outside of personality loves loses its meaning …

What we love deeply is persons – we love concrete objects, persistent realities, not mere interactions. A process may generate love, but the love is directed primarily not toward the process, but toward the continuing persons who generate that process.

King subordinates everything to the flourishing of human persons because goodness in this world has no home other than that of persons. Their wellbeing is what makes the events of our lives and of our collective history worthy of effort and care. In order to demonstrate that we are worth the struggle within and among ourselves, King sought to find love between the races and classes on the basis of philosophical claims about personhood. A decade after his dissertation, he was at the forefront of the Civil Rights movement, marching to Montgomery.

Can we still grasp and live the hope that King found? Capitalism, imperialism, nationalism, racism – like iron filings near a magnet, all these historical forces seem to be pulled together today into one fatal, immiserating direction. They teach us hateful ways to behave and promote heinous vices such as pride and greed. Desires flee beyond prudent limits and rush toward disaster. It seems we are not worth all that we used to think we are worth. Can we replace our narcissism with a virtuous self-regard? The philosophical tradition of personalism tells us that we can and do have hope for our future.


King’s hope came from his understanding of Christianity through the philosophy of personalism. He largely acquired this line of thought during his graduate studies at Boston. His advisors in Divinity School had been students of Borden Parker Bowne (1847-1910), the first philosophy professor at Boston University. Bowne founded Boston personalism, which, with William James’s pragmatism, was one of the two earliest American schools of philosophy. For Bowne, personhood is not the bundles of characteristics we call ‘personality’. Instead, it is the intelligence that makes reality coherent and meaningful. The core of his thought is that personhood is ‘the deepest thing in existence … [with] intellect as the concrete realisation and source’ of being and causality.

Bowne says that if we dismiss abstractions because they are static and have no force in the world, what is left is solely the ‘power of action’. Action for Bowne is intelligence understood as a force that activates the concrete reality of things. This reality is not static substance but the ceaseless business of the effect that entities have on other entities. Personhood is the non-material and non-biological power of relations among things, which activates all the processes of the world. Reality itself is thus deeply personal. Without personhood, it would be atomised and inactive – and therefore unintelligible. In Bowne’s view, only the concept of intelligent selves is adequate for explaining how things are constituted and inter-related. Being is nothing without causality; causality is nothing without intelligence. Reality is nothing without idea; idea is nothing without reality. This intimate connection of mind and the world means that nothing can be understood apart from the intelligence that perceives and understands it, replacing inert substances with the ever-flowing labours of our human need to find meaning in life as we encounter it.

Personalism always begins its analysis of reality with the person at the centre of consciousness

Bowne’s ideas had many predecessors, from Latin Christianity through Immanuel Kant, using many different theories and concepts, about what a human being is and about the personhood of God in its relation to our own personhood. His forceful argumentation influenced James, who helped found the American philosophical tradition of pragmatism shortly after Bowne’s first books were published and who drew increasingly close to personalism, as did the idealist philosopher Josiah Royce. Bowne was at the centre of this troika of canonical American philosophers at the turn of the 20th century. His teaching rippled out through personalist philosophers on the West Coast and through his students at Boston, notably Edgar S Brightman and Harold DeWulf, both of whom later became teachers of King.

Many other forms of personalism had been developed in Europe in the previous century: theistic and non-theistic, socialist or communitarian and libertarian, abstractly metaphysical and concretely ethical. It is more an approach to thinking than a method, doctrine or school. Personalism always begins its analysis of reality with the person at the centre of consciousness, to which it attaches the most profound worth. Some versions develop this through ontology or metaphysics; some, through theologies associated with most denominations of the Abrahamic religions; and some, through the intersubjective and communitarian nature of human life. My own version makes the structure of moral meaningfulness the first step and first philosophy, as I will explain below. All versions seek an integrated, ethically strong comprehension of personhood as the heart of the life of humankind.

Though personalism continues to be a field of robust philosophical research, in American academic philosophy after the Second World War it faded under the hegemony of analytic philosophy. But in King’s hands it became forceful as a practice for justice and other moral ends. Its resources have not been exhausted. Careful revision and updating can make it a source of illumination and hope in the circumstances we face a half-century after King.

Why should we update personalism, and what useful purpose will this serve? Our ideas about the nature of human beings are today undergoing a severe challenge by the new philosophies of transhumanism. Through personalism, we can understand and appreciate our purposes and obligations, as well as the dangers posed by transhumanism.

The best known of these transhumanist philosophies is effective altruism (EA). The Centre for Effective Altruism was founded at the University of Oxford in 2012 by Toby Ord and William MacAskill; largely inspired by Peter Singer’s utilitarianism, EA has been an influential movement of our time. As MacAskill defines it in Doing Good Better (2015):

Effective altruism is about asking, ‘How can I make the biggest difference I can?’ And using evidence and careful reasoning to try to find an answer. It takes a scientific approach to doing good.

This is not as clear cut as it might seem, and it has often led to the uncomfortable conclusion that the accumulation of capital by the wealthy is morally necessary in order to affect the world for the better in the future, largely regardless of the consequences for living persons. Its proponents argue that society does not sufficiently plan for the distant future and fails to store up the wealth that our successors will need to solve social and existential challenges.

Other transhumanist theories include longtermism, the idea that we have a moral obligation to provide for the flourishing of successor bioforms and machinic entities in the very distant future, at times regardless of consequences for those now living and their proximate next generations. There is also a kind of rationalism that justifies the moral calculations on which provision for the future instead of for the living is based; cosmism, the vision for exploration and colonisation of other worlds; and transhumanism, which aspires to assemble technologies for the evolution of humankind into successor species or for our replacement by other entities as an inevitable and thereby moral duty. All of these, including the various versions, are sometimes named by the acronym TESCREAL (transhumanism, extropianism, singularitarianism, cosmism, rationalism, effective altruism, longtermism). Here I refer to these as ‘transhumanism’.

The core argument common to these lines of thinking, according to the philosopher Émile Torres writing in 2021, is that:

[W]hen one takes the cosmic view, it becomes clear that our civilisation could persist for an incredibly long time and there could come to be an unfathomably large number of people in the future. Longtermists thus reason that the far future could contain way more value than exists today, or has existed so far in human history, which stretches back some 300,000 years.

From this point of view, human suffering today matters little by the numbers. Nuclear war, environmental collapse, injustice and oppression, tyranny, and oppression by intelligent technology are mere ripples on the surface of the ocean of history.

This idea of the agency of the inorganic is one of the key arguments for decentring the human

Each element of these transhumanist ideologies regards human personhood as a thing that is expiring and therefore to be replaced. As the longtermist Richard Sutton told the World Artificial Intelligence Conference in 2023: ‘it behooves us [humans] … to bow out … We should not resist succession.’ Their proponents argue for the factual truth of their predictions as a way to try to ensure the realisations of their prophecies. According to the theorist Eliezer Yudkowsky, by ‘internalising the lessons of probability theory’ to become ‘perfect Bayesians’, we will have ‘reason in the face of uncertainty’. Such calculations will open a ‘vastly greater space of possibilities than does the term “Homo sapiens”.’

A personalist approach deflates these transhumanist claims. As the historian of science Jessica Riskin has argued, a close examination of the science of artificial intelligence demonstrates that the only intelligence in machines is what people put into them. It is really a sleight-of-hand; there is always a human behind the curtain turning the wizard wheels. As she put it in The New York Review of Books in 2023:

Turing’s literary dialogues seem to me to indicate what’s wrong with Turing’s science as an approach to intelligence. They suggest that an authentic humanlike intelligence resides in personhood, in an interlocutor within, not just the superficial appearance of an interlocutor without; that intelligence is a feature of the world and not a figment of the imagination.

Longtermists’ notions of future entities lack everything we know about conscious intelligence because they use consciousness or living beings as empty black-box words into which even meaningless notions will fit. Effective altruists dismiss the worth attributable to every human, squashing it by calculations that cannot prescribe moral value, whatever these proponents claim. As we can see in the theories of longtermists such as Nick Bostrom and effective altruists such as Sam Bankman-Fried, instead of working with human ethical values, they work with numerical values, ignoring the massive body of thought from anthropologists such as Webb Keane and from phenomenologists such as Rasmus Dyring, Cheryl Mattingly and Thomas Wentzer showing that values are neither empirical nor quantifiable but nonetheless real forces in human affairs. Transhumanism as a whole assigns agency to alien beings and electronic entities that do not exist – and perhaps are inconceivable.

This idea of the agency of the inorganic is one of the key arguments for decentring the human. Consider, for example, salt. Salt affords certain effects in certain conditions: it produces a specific taste, it corrodes other materials, it serves certain functions in organisms. But it is humans who organise these events under the concept of causality. What salt does, it does without consciousness. Consciousness neither starts nor halts its effects, broadly speaking. What sense is there, then, in saying that salt has agency when it is more illuminating to say that it is a cause of effects under some conditions?

In ordinary language, we frequently speak of machinery or ideas ‘doing’ things in our lives. But they do nothing. People – human persons – produce, operate and apply their creations. The problem with assigning agency, even informally, to the nonhuman is that this disguises the strength of human control, limited though it is in other respects. It leaves us unaware when a more toxic and cunning human drives to take control because we are busy trying to control the world rather than ourselves. Although some people think that machines or ideas are in control of them, it is really other humans. If we overlook this truth, we accept an untruth – an untruth that condemns us to the mercy of our worst drives and behaviours. When we devalue humanity, we unleash our self-destructive drives, thereby turning reason into destructive irrationality. In this way, we are in fact governed by our own human drive for self-destruction.

This drive seems to differentiate us from other animals as much as language or historicity do. If we provoke this drive too much, we shall have nowhere else to turn in our struggle to flourish in the natural world. We must, instead, search out our integrity and worth because the alternative is despair.

The great and encompassing thing that humans create is our story: human history, the sum of our behaviour and our deeds. We create it with and amid the world around us out of our need to make sense of the world. This need, which builds our moral life, is part of what drives everything we do. It drives the ways we pursue survival, for, without a sense of meaning, we have little will to survive. The pursuit of survival can lead us to meaningfulness but, if it fails to do so, the pursuit itself ceases. We guide ourselves by the stories we choose, for storytelling inhabits all ways of knowing and acting. If the meaning we seek as human persons is overtaken by the story that our self-destructive drive presents in the form of transhumanism, we shall not survive.

Persons are worth more than even justice and goodness are, because it is for the sake of persons that we fight for justice and goodness. In the face of possible profound changes, it often seems we must choose between being good and just to ourselves, and being good and just toward nature. The possibility of these radical changes legitimately requires that we profoundly deflate our anthropocentrism, since overblown self-regard has served us poorly. But how do we do this while encouraging our fraught capabilities and appreciating the worth of our flawed species?

The kind of personalism that I have developed out of Bowne’s ideas as a response to this and other questions I call moral agency personalism. Moral agency is the activity of judging and choosing between good and evil, right and wrong, justice and injustice. In my view, every thing that has such moral agency is a person, and all persons are moral agents. (The evidence that some nonhuman species make moral choices, sometimes based on memory and history, has been accumulating.) Adding this possibility to personalism formally recognises worth in all persons, nonhuman as well as human. As a belief and a practice, it can ground a virtuous, as opposed to vicious, self-regard that human and nonhuman persons can exercise for themselves and for other persons. This kind of self-regard is distinct from self-importance.

We can develop a moral agency personalism that has some of the resources we need in facing the human future. We can find these by altering some fundamental concepts of personalism. These updates include: accepting the fact of nonhuman moral agents or persons; including the body in our understanding of individual lives and of interpersonal relations; and rethinking the idealist ontology in personalism in order to make it an ethics-as-first-philosophy approach, with less emphasis on ontology. The guiding idea of these changes is that, in making moral sense out of experience, personal moral agency enlarges our relations to the whole range of our lives and our care for all beings.

We need to respect ourselves as persons with the power to decide not to continue to harm

Personalism gives us robust resources for identifying our worth and for believing in it. It can encourage us to enhance our worth by our acts in seeking goodness, compassion and justice, and guide us to the richest possible moral life. Because our personhood is the home base of our point of view, there is no way forward other than to maintain our integrity while learning what we must in order to thrive.

The initial and most basic of these resources we should tap is the strength not to do more harm. We are the ones who deploy transhumanist projects into the only world that sustains us. We are the ones degrading the environment. And we are the only ones who can stop us from doing both. For this, we need to respect ourselves as persons with the power to decide not to continue to harm. This is the minimum we must do.

Respecting the moral worth of persons also ignites our capacity to care for others. We respond with aid to calls for help when we learn to recognise moral obligation pertaining to every person, including ourselves, and toward every other person. Furthermore, our humanitarian disposition is frequently a sure way to developing sympathy for the natural world and the life within it.

Understanding our personal moral agency enables a wise combination of the two general forces of moral action: power and compassion. Power is the logic by which we carry ideas and lines of thought to fulfilment in activity. Compassion is the potentially unbounded lovingkindness with which we temper power and extend love to widening spheres in our lives. So far as we know, we are the only living beings who can use these forces in moral decision-making. But even if other beings have moral personhood, nothing of the sort relieves us of the moral obligation that our possession of these two capabilities makes it possible to accept and to follow.

We possess our history, just as we make it – another resource that is unique to us, so far as we know. History is the engine of self-awareness. As the substance of all that we have done and the actual conditions for the possibility of all that is and will be, historical consciousness serves us as the indispensable locus of reflection and deliberation. No unchanging and antiquated images of ourselves restrain our understanding of history because we create the past anew whenever we study it and reflect on it. It is therefore the great endowment for a renewed humanistic extension of personhood to all humankind and to all life.

There are two more resources, pointing to opposite ends of the spectrum of our concerns. The first is that the personalist grasp of what we are worth supports democracy. Democracy has depended on a powerful conception of personal agency and responsibility that cultural and political changes now challenge, in addition to the material issues of human life in the Anthropocene era. These social and natural developments closely reflect each other. Learning to live together is the worthy goal of democracy. But if we are to pursue concord and peace by that road, we must value ourselves, accept our moral nature with its obligations, submit our desires to what the moral worth of every living being requires of us, and work in response to present and patent human suffering and real human joy.

At the opposite end, on the cosmic scale, lies another possibility for virtuous human self-regard afforded us by personalism. Simply put, it is this: it might become clear to us that the universe is constitutively pervaded by consciousness, or is conscious in all its parts, or is inside of a super-consciousness. These are versions of the notion of cosmic consciousness called panpsychism. Panpsychism is not just about what we can know or do but about reality itself. This appeals to those who have for a moment felt the life of the universe in a small experience and do not want to dismiss what that feeling says and means to them just because it is not empirically verifiable. In our best moments, our lives feel epiphanous.

The moral agency of persons thrives when agents act in obligation to their individual and collective selves

At the same time, however, panpsychism can conflict with the empiricism that is so valuable because it is used to make things that work well for us. And yet other kinds of things, such as erotic love and spirituality, also work well for us and are not conducive to the usual demands of empiricism. For now, it is easy to think that a universal consciousness makes our consciousness unimportant, but there might be ways of getting the opposite outcome. Current advances in physics and biology are starting to support the belief that our consciousness affects reality by working with reality as a consciousness that includes ours. That is, our observing and predicting are inside, not outside, the phenomena we encounter. We are not the crown jewels of creation, but our self-referentiality, our critical awareness and our moral lives form personhood as an important part of a universe that is thereby less alien and cold.

If a suitable form of panpsychism is true, human personhood means more to reality than is usually thought. This kind of personalism puts us into a community or, rather, into many communities made up of conscious beings capable of moral responsibility. The moral agency of persons thrives when agents reflectively act in obligation to their individual and collective selves rather than in seeing themselves through the needs of imagined others in the undetermined future.

What King observed in Montgomery airport in 1965 was actual persons developing their moral purchase with each other. He saw this as the processes of goodness and love at work in their proper sphere: our common existence. King wanted us not only to recognise the unique and infinite value of every person, but to understand it so powerfully that we would feel ourselves obliged to take the action that this recognition requires. As he wrote, we need only look around us at the struggles for a decent and free life that others wage to sense the profundity of human worth and to see that we all depend on one another. That this has the power to inspire us to fight for change sustained his hopes.

We face an urgent present choice. We might prefer that algorithms or despots act for us because our own power of judgment is too explosive to manage. That would suit the purposes of infomaniacal hypercapitalism, which seeks to control consumers rather than to enrich persons. But turning over our judgment to machines does not lock away our power to destroy ourselves and others. We must govern ourselves even as we evolve. This requires an enduring connection to our humanity and a willingness to work hard with one another. This can be successful only if and when we hold fast to all that we are.
