ππ Di Terror of Threes in di Heavens and on Earth
Physicists don waka reach to explore how phenomena wey involve groups of three fit scatter yawa. A new three-body problem, dem dey warn, fit lead to not only global races for new armaments but also thermonuclear war. π£ππ₯
Isaac Newton bin dey baffled. E don already gain fame sake of im discovery of how gravity dey hold di universe together and for using dat knowledge to predict di movements of celestial bodies, like di moon’s path around di Earth. Now, as e take include di gravitational pulls of di sun, e wan improve im predictions about di moon. Instead, e make am worse.
Di setback, wey Isaac Newton friend Edmond Halley report, “make im head dey pain am, and e dey keep am awake so tey e no wan think about am again.” Newton feel di pain of im defeat so well say e remember am even as e dey old.
Till today, dem dey call am di three-body problem. E dey famous for science and science fiction sake of di orbital disturbances and chaotic phenomena wey e dey cause. Lately, atomic experts and military planners don dey worry about am. Dem dey warn say as Beijing dey expand dia nuclear arsenal rapidly, di world of atomic superpowers fit go from two to three. Di outcome, dem talk, fit represent one dangerous new kind of unthinkable. π₯ππ
Dis looming era fit encourage “countries to resort to nuclear weapons in a crisis,” Andrew F. Krepinevich Jr., one senior fellow for Center for a New American Security, recently don warn. E talk say di natural instabilities wey physicists and astronomers don observe fit serve as warning signs. Experts dey say di tripolar age fit put human survival for risk. But dem also dey point out lessons from nature wey involve groups of three — starting with Newton’s own observations — wey fit shine light on di matter and suggest possible ways forward. But for now, no solution dey stand out. Di world’s nuclear thinkers dey find di matter as difficult to solve as Newton find am. π§ ππ€
“We get one conceptual problem,” Ernest J. Moniz, one physicist wey serve as di secretary of energy for di Obama administration, talk. “We need change di traditional approach wey involve equalizing weapons or strategic delivery systems, but how to do dat still no clear.”
France A. CΓ³rdova, one astrophysicist wey don serve as di director of di National Science Foundation, talk say di study of three-body phenomena for di natural sciences fit still help reveal di military risks wey dey involved. “Tins dey change rapidly,” e talk. “Anything wey go help for understanding, na great something.”
Di people wey dey worry about security dey call for expansion of di American arsenal as response to China’s nuclear rise and di threat of Beijing aligning with Moscow. Di people wey dey advocate for peace see opportunity to tackle di three-body problem in smaller, more manageable parts. Dem talk say Washington suppose deal with di two superpowers independently and seek diplomatic solutions wey go reinforce stability between two bodies.
Recently, di Biden administration don call for further simplification. Jake Sullivan, di national security adviser, argue say di American response suppose focus less on di quantity of di nation’s nuclear arms and more on di quality. To successfully deter attacks, e talk for one speech, di American military no need weapons wey “outnumber di combined total of our competitors.”
For everyday life, groups of twos and threes fit seem inconsequential. If two friends join another person, e bring di total to three. Na wetin scientists call linear increase.
But for many aspects of nature, threes get one kind of almost magical power wey fit scatter yawa, e fit become more pass wetin dem expect. Scientists call am nonlinearities. In short, di transition from two to three fit produce one unexpected jump in complexity, as Newton experience am to im dismay.
“Our intuition no go fit help us,” Michael Weisberg, one philosopher of science for University of Pennsylvania, talk about di three-body chaos. Steven Strogatz, one applied mathematician for Cornell University, agree: “Threes dey inherently problematic. Tins dey get k-leg.”
Atoms show di complexity jump. Hydrogen, di simplest atom, get two main parts — one nucleus and one electron wey dey orbit around di nucleus. Physicists fit predict with great accuracy di future states of di subatomic particle, talk Michael S. Lubell, one professor of physics for City College of New York.
But helium — di next larger atom — get two electrons. Di interplay of those two particles with di atom’s nucleus scatter dem enter complicated state wey science no fit explain. “Dem no get exact solution,” Dr. Lubell talk. “You no go fit find out wetin dey happun to dia behavior, dia location, or anything else. E no follow pattern. Tins scatter yawa.”
Surprisingly, di jump in disorganization still show face for di world’s oceans and atmosphere — for whirlpools and maelstroms, tornadoes and hurricanes. If two of di swirling bodies come close, dem go move for straight lines or dem go circle each other.
“With three, tins immediately become more complicated,” Michael J. Shelley, one specialist in fluid dynamics for New York University, talk. “Dem fit collapse into each other. E go scatter yawa and e no go dey predictable. E get big difference.”
Notably, di jump also dey show face for human life as groups of three fit make social complexities skyrocket — especially for young families. If two children dey, dem get one kind of relationship. But if dem add one more pikin, di number of ties wey dey among di children go increase to seven — dem go get three one-on-one relationships, three one-on-two relationships, and one group relationship. Parents go come dey outnumbered, and bedlam fit start.
For di cosmos, stars also dey come together for chaotic threesome. For di popular science fiction novel, “The Three-Body Problem,” wey Liu Cixin write, e feature three stars wey dey whirl around one another for unruly orbits. As result, di planet Trisolaris suffer cycles of blistering heat and icy cold wey fit reverse within minutes, and e produce one alien civilization wey dey obsessed with survival.
Clusters of three stars, however, dey relatively rare for di universe sake of di stragglers wey dey wide orbits fit either get ejected or absorbed by passing star systems. “Roughly, for every two binaries, dem get one triple,” Andrei A. Tokovinin, one astronomer for di Cerro Tololo Inter-American Observatory wey get headquarters for La Serena, Chile, talk.
Di Cold War — despite all di terrors and crises wey e bring — avoid nuclear war, partly sake of say di mature structures for di conflict follow di binary stability wey astronomers see for di heavens and wey young families see for di relatively simple play of two children.
Di era of most serious nuclear tension begin as di world’s first thermonuclear weapons dey tested by Washington for 1952 and Moscow for 1955. Based on dia nature, di weapons fit produce blasts wey dey thousand times more powerful pass di Hiroshima bomb. Di arms race wey follow feed di Cold War’s fear of mutual annihilation — wey dem even mock for di classic 1964 film, “Dr. Strangelove.”
Soon, di antagonists adopt force parity as one way to reduce di risk of conflict. Negotiated agreements set Moscow and Washington on roughly equal ground wey suppose replace war with tense stalemates — just like di case between Russia and di United States till now.
“We dey for one stable equality,” William I. Newman, one astrophysics professor for University of California, Los Angeles, wey dey help University of California manage Los Alamos weapons lab, talk. “Any deviation from dat go increase di instability.”
Di imminent deviation na Beijing plan to produce 1,500 nuclear warheads by 2035, as Pentagon estimate. If dem achieve am, e go represent one fivefold increase from di “minimum deterrent” wey Beijing don get for more than half a century, and e go make am one nuclear equal to Moscow and Washington.
Dr. Newman call di tripolar state “much less resilient” pass di bipolar standoff. Even so, theorists of three-body problem see different ways wey di unthinkable fit avoid.
For example, Dr. Krepinevich, for one Foreign Affairs article last year, argue say Moscow fit become economically and strategically irrelevant, and leave Beijing and Washington to “navigate dia way to one new bipolar equilibrium.” Di recent armed uprising for Russia no just show say Moscow dey weak, but e also highlight di threat of new instability for one atomic superpower.
On another hand, Siegfried S. Hecker, one former director of Los Alamos weapons laboratory for New Mexico, argue say Washington suppose aim to deal with di rival superpowers separately.
“I no see Russia and China come together” for atomic strategies, e talk. “Na two bipolars I see.” As di war for Ukraine dey happen and Washington no dey interact much with Moscow, Dr. Hecker add say now na good time to “work with di Chinese” to build one two-body relationship.
Di main worry of military planners na say Beijing no go just achieve weapon parity with Washington, but e fit also form military alliance with Moscow.
“We no dey see one full-fledged, well-established, long-lasting, and resilient geopolitical alliance yet,” Gen. Mark A. Milley, di outgoing chairman of di Joint Chiefs of Staff, tell Foreign Affairs magazine last month. “But fit e happun for di future? E fit happun, and we need to dey vigilant, and we need to do everything we fit to make sure say e no happun.”
Security-minded analysts dey call for quick expansion of di American arsenal. For March, di Livermore weapons lab for California publish one lengthy report wey argue say di buildup suppose begin for early 2026 as New START, one of di last major arms control agreements between Moscow and Washington, expire. Dem talk say plenty retired warheads suppose dey redeployed on missiles, bombers, and submarines.
Despite proposals make Washington match di combined forces of Beijing and Moscow, analysts talk say efforts to achieve weapon parity likely go fail. Na because di rivals go see wetin dey happun and go most likely expand dia own arsenals in response.
Parity go dey “constantly sought but never achieved,” like Dr. Krepinevich put am last year for Foreign Affairs. Other analysts agree. Rather than weapon equivalence, dem dey see endless arms races wey fit increase di risk of miscalculation and war.
Despite di prospect of complicated new threats and uncertainties from three atomic superpowers, Newton’s curse still fit offer practical advice, talk Melvin G. Deaile, director of di School of Advanced Nuclear Deterrence Studies for Maxwell Air Force Base for Montgomery, Ala.
Most basically, Dr. Deaile talk say di armed forces of di United States suppose adopt one strategy of unrelenting flexibility sake of di turmoil wey go come. “Static deterrence no go do,” e talk for one Air Force journal. “Deterrence suppose become agile.”
For one interview, Dr. Deaile express confidence say di existential threats of di tripolar world fit still dey successfully managed.
Dr. Deaile talk say e draw inspiration from Carl von Clausewitz, di Prussian war theorist of di early 19th century. E talk say di theorist na pioneer for applying three-body logic to conflict management. For im military classic, “On War,” Clausewitz mention not only Newton by name, but also one standard demonstration wey show how one object wey suspend over three magnets dey make unpredictable moves.
“Yes, di system na dynamic,” Dr. Deaile talk about di tripolar world. “Yes, e dey constantly change. But we suppose realize say dis problem dey bounded and e get some stability.” Despite di likelihood of clashes among three atomic superpowers, e talk say “there still dey pathways to maintain stability.”
Dr. Deaile, one retired Air Force colonel, na im talk one similar approach to Dr. Hecker, di former director of Los Alamos, wey be di birthplace of di bomb. Separately, each expert argue say to maintain one uneasy peace among nuclear foes, dem suppose talk, share concerns, and take small steps at confidence-building. “We suppose keep di lines of communication open and dey interact,” Dr. Deaile talk.
After all, e add, “None of these nations want to wipe each other off di face of di earth.” ποΈπ€π£π

ππ The Terror of Threes in the Heavens and on Earth
Physicists have ventured into exploring how phenomena involving groups of three can wreak havoc. A new three-body problem, they warn, could lead to not only global races for new armaments but also thermonuclear war. π£ππ₯
Isaac Newton was perplexed. He had already gained fame for his discovery of how gravity holds the universe together and for using that knowledge to predict the movements of celestial bodies, such as the moon’s path around the Earth. Now, by considering the sun’s gravitational pulls, he aimed to improve his predictions about the moon. Instead, it made them worse.
The setback, reported by Isaac Newton’s friend Edmond Halley, “gave him a headache and kept him awake so much that he decided to think about it no more.” Newton felt the pain of his defeat so deeply that he recalled it even in his old age.
Today, it is known as the three-body problem. It is famous in both science and science fiction for its orbital disturbances and chaotic phenomena it can cause. Recently, atomic experts and military planners have become concerned about it. They warn that as Beijing rapidly expands its nuclear arsenal, the world of atomic superpowers could transition from two to three. The outcome, they say, could represent a dangerous new kind of unthinkable. π₯ππ
This looming era could encourage “countries to resort to nuclear weapons in a crisis,” recently warned Andrew F. Krepinevich Jr., a senior fellow at the Center for a New American Security. He cited the natural instabilities observed by physicists and astronomers as a warning sign. Experts say the tripolar age could put human survival at risk. But they also point to lessons from nature that involve groups of three β starting with Newton’s own observations β that can shed light on the issue and suggest possible ways forward. However, no clear solution has emerged thus far. The world’s nuclear thinkers are finding the matter as difficult to solve as Newton did. π§ ππ€
“We have a conceptual problem,” said Ernest J. Moniz, a physicist who served as the secretary of energy in the Obama administration. “We need to change the traditional approach that involves equalizing weapons or strategic delivery systems, but how to do that is still unclear.”
France A. CΓ³rdova, an astrophysicist and former director of the National Science Foundation, said that studying three-body phenomena in the natural sciences can still help reveal the military risks involved. “Things are changing very rapidly,” she said. “Anything that helps in understanding that is great.”
Security-minded analysts are calling for a quick expansion of the American arsenal in response to China’s nuclear rise and the threat of Beijing aligning with Moscow. Advocates for peace see an opportunity to tackle the three-body problem in smaller, more manageable parts. They argue that Washington should deal with the two superpowers independently and seek diplomatic solutions that reinforce stability between two bodies.

To successfully deter attacks, he said in a speech, the American military has no need for weapons that “outnumber the combined total of our competitors.”
In everyday life, groups of twos and threes may seem inconsequential. When two friends join another person, it brings the total to three. It’s what scientists call a linear increase.
But in many aspects of nature, threes possess a kind of almost magical power to disrupt. They can become more than what is expected. Scientists call them nonlinearities. In short, the transition from two to three can result in an unexpected jump in complexity, as Newton experienced to his dismay.
“Our intuitions cannot guide us,” said Michael Weisberg, a philosopher of science at the University of Pennsylvania, about the chaos of the three-body problem. Steven Strogatz, an applied mathematician at Cornell University, agreed: “Threes are inherently problematic. Things get tricky.”
Atoms illustrate this jump in complexity. Hydrogen, the simplest atom, has two main parts β a nucleus and one electron that orbits around the nucleus. Physicists can predict with great accuracy the future states of the subatomic particle, said Michael S. Lubell, a professor of physics at the City College of New York.
But helium β the next larger atom β has two electrons. The interaction of those two particles with the atom’s nucleus throws them into a complicated state that science cannot explain. “There’s no exact solution,” Dr. Lubell said. “You can’t find out what’s happening to their behavior, their location, or anything else. It doesn’t follow a pattern. Things get chaotic.”
Surprisingly, this jump in disorganization also shows up in the world’s oceans and atmosphere β in whirlpools and maelstroms, tornadoes and hurricanes. When two of the swirling bodies come close, they move in straight lines or circle each other.
“With three, things immediately become more complicated,” said Michael J. Shelley, a specialist in fluid dynamics at New York University. “They can collapse into each other. It becomes highly disordered and unpredictable. There’s a huge difference.”
Notably, this jump also manifests in human life as groups of three cause social complexities to soar β especially in young families. With two children, there is one kind of relationship. But adding one more child results in seven different ties among the siblings β three one-on-one relationships, three one-on-two relationships, and one group relationship. Parents are outnumbered, and bedlam can ensue.
In the cosmos, stars also come together in chaotic threesomes. The celebrated science fiction novel “The Three-Body Problem” by Liu Cixin features three stars that whirl around one another in unruly orbits. As a result, the planet Trisolaris suffers cycles of blistering heat and icy cold that can reverse within minutes, producing an alien civilization obsessed with survival.
Clusters of three stars, however, are relatively rare in the universe because stragglers in wide orbits often get ejected or absorbed by passing star systems. “Roughly, for every two binaries, there’s one triple,” said Andrei A. Tokovinin, an astronomer at the Cerro Tololo Inter-American Observatory, which has headquarters in La Serena, Chile.
The Cold War β despite all its terrors and crises β avoided nuclear war, partly because its mature structures reflected the binary stability observed in the heavens and experienced in the relatively simple dynamics of two children at play.
The era of most serious nuclear tension began as the world’s first thermonuclear weapons were tested by Washington in 1952 and Moscow in 1955. By nature, these weapons could produce blasts a thousand times more powerful than the Hiroshima bomb. The ensuing arms race fueled the Cold War’s fear of mutual annihilation β ridiculed in the classic 1964 film “Dr. Strangelove.”
Soon, the antagonists embraced force parity as a way to reduce the risk of conflict. Negotiated agreements placed Moscow and Washington on roughly equal footing meant to replace war with tense stalemates β as is the case with Russia and the United States today.
“We are in a stable equality,” said William I. Newman, a professor of astrophysics at the University of California, Los Angeles, who assists in the University of California’s management of the Los Alamos weapons lab. “Any departure from that will increase the instability.”
The impending departure is Beijing’s plan to produce 1,500 nuclear warheads by 2035, as estimated by the Pentagon. If achieved, this rise would represent a fivefold increase from the “minimum deterrent” that Beijing possessed for over half a century and would make it a nuclear peer of Moscow and Washington.
Dr. Newman refers to the tripolar state as “much less resilient” than the bipolar standoff. Even so, three-body theorists see several ways in which the unthinkable might be avoided.
For instance, Dr. Krepinevich, in a Foreign Affairs article last year, argued that Moscow could fade into economic and strategic insignificance, leaving a strong Beijing and Washington to “navigate their way to a new bipolar equilibrium.” The recent armed uprising in Russia not only demonstrated Moscow’s weakness but also highlighted the threat of new instability in an atomic superpower.
On a different note, Siegfried S. Hecker, a former director of the Los Alamos weapons laboratory in New Mexico, argued that Washington should aim to deal with the rival superpowers as separate entities.
“I don’t see Russia and China getting together” on atomic strategies, he said. “I see it as two bipolars.” As the war in Ukraine rages and Washington has little interaction with Moscow, Dr. Hecker added, now is a good time “to work with the Chinese” in building a two-body relationship.
The main concern of military planners is that Beijing will not only achieve weapon parity with Washington but also form a military alliance with Moscow.
“We are not yet seeing a full-fledged, well-established, long-lasting, and resilient geopolitical alliance,” said Gen. Mark A. Milley, the outgoing chairman of the Joint Chiefs of Staff, in an interview with Foreign Affairs magazine last month. “Could that happen in the future? It could, and we need to be wary of that, and we need to do what we can to make sure that doesn’t happen.”
Security-minded analysts are calling for a rapid expansion of the American arsenal. In March, the Livermore weapons lab in California published a lengthy report arguing that the buildup should begin in early 2026 as New START, one of the last major arms control agreements between Moscow and Washington, expires. The report suggests redeploying swarms of retired warheads on missiles, bombers, and submarines.
Despite proposals for Washington to match the combined forces of Beijing and Moscow, analysts say attempts at weapon parity are likely to fail. This is because Washington’s rivals would anticipate such moves and, in response, would most likely expand their own arsenals.
Parity will be “continuously sought but never achieved,” as Dr. Krepinevich put it last year in Foreign Affairs. Other analysts agree. Instead of weapon equivalence, they foresee endless arms races whose moves and countermoves could raise the risk of miscalculation and war.
Despite the prospect of complex new threats and uncertainties from three atomic superpowers, Newton’s curse can still offer practical advice, says Melvin G. Deaile, the director of the School of Advanced Nuclear Deterrence Studies at Maxwell Air Force Base in Montgomery, Ala.
At its core, Dr. Deaile suggests that the armed forces of the United States adopt a strategy of unwavering flexibility given the tumult that lies ahead. “Static deterrence will not suffice,” he stated in an Air Force journal. “Deterrence will have to become agile.”
In an interview, Dr. Deaile expressed confidence that the existential threats of the tripolar world can still be successfully managed.
Dr. Deaile said he draws inspiration from Carl von Clausewitz, the Prussian war theorist of the early 19th century. He noted that Clausewitz was a pioneer in applying three-body logic to conflict management. In his military classic “On War,” Clausewitz not only mentioned Newton by name but also referred to a standard demonstration that illustrates how an object suspended between three magnets moves unpredictably.
“Yes, the system is dynamic,” Dr. Deaile said of the tripolar world. “Yes, it’s constantly changing. But we must recognize that this problem is bounded and has some stability.” Despite the likelihood of clashes among the three atomic superpowers, he said, “there are still pathways to maintaining stability.”
Dr. Deaile, a retired Air Force colonel, advocates a similar approach to Dr. Hecker, the former director of Los Alamos and the birthplace of the bomb. Separately, both experts argue that to maintain an uneasy peace among nuclear foes, they must talk, share concerns, and take small steps in confidence-building. “We need to keep the lines of communication open and engage with each other,” Dr. Deaile said.
After all, he added, “None of these nations want to wipe each other off the face of the earth.” ποΈπ€π£π
