This Physicist Says Electrons Spin in Quantum Physics After All. Here’s Why : ScienceAlert
‘Spin’ is a fundamental quality of fundamental particles like the electron, invoking images of a tiny sphere revolving rapidly on its axis like a planet in a shrunken solar system.
Only it isn’t. It can’t. For one thing, electrons aren’t spheres of matter but points described by the mathematics of probability.
But California Institute of Technology philosopher of physics Charles T. Sebens argues such a particle-based approach to one of the most accurate theories in physics might be misleading us.
By framing the groundwork of matter primarily in terms of fields, he says, certain peculiarities and paradoxes that emerge from a particle-centric view melt away.
“Philosophers tend to be attracted to problems that have been unsolved for a really long time,” says Sebens.
“In quantum mechanics, we have ways of predicting the results of experiments that work very well for electrons and account for a spin, but important foundational questions remain unanswered: Why do these methods work, and what’s happening inside an atom?”
For the better part of a century, physicists have wrestled with the results of experiments that suggest the smallest pieces of reality don’t look or behave anything like objects in our everyday lives.
Spin is one of these qualities. Like a whirling cue ball colliding with the inner wall of a billiard table, it carries angular momentum and influences the direction of a moving particle. Yet, unlike the cue ball, a particle’s spin can never speed up or slow down – rather, it’s always confined to a set value.
To make the basic nature of matter even harder to picture, consider the fact an electron’s size is so small that it effectively lacks volume. If it were large enough to have volume, the negative charge spread throughout that space would push on itself, tearing the electron apart.
Significantly, even if we were to be charitable and grant the electron as a particle the largest radius experiments would allow for, its rotation would overtake the speed of light – something which might or might not be a deal-breaker on this scale, but for many physicists is enough to dismiss talk of rotating electrons.
One way to make the tapestry of fundamental physics a little easier to map is to describe points of matter as actions embedded into the weave of a field and then interpret these actions as particles.
Quantum field theory (QFT) does this successfully, weaving together aspects of Einstein’s special theory of relativity, classical field theory, and the particle propositions of quantum physics.
It’s not a controversial theory, yet there is still debate over whether those fields are fundamental – existing even if the blips that ripple through them were to fall silent – or if particles are the main actors that represent the vital information and fields are just a convenient script.
To us, it might seem like a trivial distinction. But to philosophers like Sebens, the consequences are worth exploring.
As he explained in a 2019 article featured in Aeon magazine: “Sometimes progress in physics requires first backing up to reexamine, reinterpret, and revise the theories that we already have.”
That reexamination of quantum field theory emphasizes several significant advantages to making fields a priority in physics over a particle-first approach, including a model that re-imagines electrons in ways that might give us better insights into their behavior.
“In an atom, the electron is often depicted as a cloud showing where the electron might be found, but I think that the electron is actually physically spread out over that cloud,” Sebens says.
By being physically spread out through a field rather than confined to a point, an electron might actually rotate in ways that are less mathematical constructs and more a physical description.
Although it would still not be anything like a tiny planet in a solar system, this rotating electron would at least move at a speed that doesn’t challenge any laws.
Just how this diffuse spread of negatively charged matter resists blowing itself apart is a question Sebens doesn’t have an answer for. But by focusing on the field aspects of a spread-out electron, he feels any solutions would make more sense than issues that arise from particles of infinite confinement.
There’s a quote that has become folklore in the halls of quantum theorists – “Shut up and calculate.” It’s become a saying synonymous with the aphantasic landscape of the quantum realm, where imagery and metaphor fail to compete with the uncanny precision of pure mathematics.
Every now and then, though, it’s important to pause our calculations and indulge in challenging a few old assumptions – and maybe even turn around for a new perspective on the fundamentals of physics.

Earth’s inner core seems to be slowing its spin
The provocative findings come after years of research and deep scientific disagreements about the core and how it influences some of the most fundamental aspects of our planet, including the length of a day and fluctuations in Earth’s magnetic field.
Three thousand miles below the surface, a scorching hot ball of solid iron floats inside a liquid outer core. Geologists believe that the energy released by the inner core causes the liquid in the outer core to move, generating electrical currents that in turn spawn a magnetic field surrounding the planet. This magnetic shielding protects organisms on the surface from the most damaging cosmic radiation.
Don’t panic. The core’s slowing down isn’t the beginning of the end times. The same thing appears to have happened in the late 1960s and early 1970s, and the study authors at Peking University in China suggest it may represent a 70-year cycle of the core’s spin speeding up and slowing down.
But while other experts praised the rigor of the analysis, the study will sharpen, not settle, the fierce scientific debate about what the mysterious metal sphere at the center of the Earth is up to.
“It’s only contentious because we can’t figure it out,” said John Vidale, a geophysicist at the University of Southern California. “It’s probably benign, but we don’t want to have things we don’t understand deep in the Earth.”
The new study was led by Xiaodong Song, a geoscientist at Peking University whose work in 1996 first brought forward the evidence that the core was doing its own thing. Buried beneath the mantle and the crust, the core is too deep to visualize directly, but scientists can use seismic waves triggered by earthquakes to infer what’s happening in the planet’s innards. Seismic waves travel at different speeds depending on the density and temperature of the rock, so they act as a kind of X-ray for Earth.
The study examined seismic waves that traveled from the sites of earthquakes to sensors on the flip side of the planet, passing through the core on the way. By comparing waves from similar earthquakes that struck the same spot over the years, the scientists were able to search for and analyze time lags and perturbations in the waves that gave them indirect information about the core — or as some scientists call it, the planet within our planet.
“The inner core is the deepest layer of Earth, and its relative rotation is one of the most intriguing and challenging problems in deep-earth science,” Song said in an email.
The behavior of the core may be linked to minute changes in the length of a day, though the precise details are a matter of debate. The length of a day has been growing by milliseconds over centuries because of other forces, including the moon’s pull on Earth. But ultraprecise atomic clocks have measured mysterious fluctuations.
These variations may line up with changes in the core’s rotation, Song and colleagues argue. The new paper finds that, when they remove predictable fluctuations in the length of a day due to the moon’s tidal forces, there are changes that appear to track with the 70-year oscillations in the inner core’s rotation.
Paul Richards, a seismologist at the Lamont-Doherty Earth Observatory at Columbia University, worked with Song to put forward the initial evidence that the core was spinning faster than the rest of the planet.
“Most of us assumed that the inner core rotated at a steady rate that was slightly different from the Earth,” Richards said. “The evidence accumulates, and this paper shows that the evidence for [faster] rotation is strong before about 2009, and basically dies off in subsequent years.”
Still, he cautioned that things get speculative quickly when trying to understand the influence of the core on other phenomena. That’s because the behavior of the core itself is still a contested question — with simplistic assumptions increasingly refined over the years.
For example, there are lines of evidence to support other ideas about how Earth’s core is behaving. USC’s Vidale has studied seismic waves generated by nuclear explosions, and he favors a shorter, six-year oscillation for the core’s rate of rotation.
Lianxing Wen, a seismologist at Stony Brook University, rejects altogether the idea that the core is rotating independently. He argues that changes over time to the surface of the inner core are a more plausible explanation for the seismic data.
“This study misinterprets the seismic signals that are caused by episodic changes of the Earth’s inner core surface,” Wen said in an email. He added that the idea the inner core is rotating independently of the surface “provides an inconsistent explanation to the seismic data even if we assume it is true.”
What geoscientists do agree on is that as more data have accrued, many of the initial ideas about the core’s behavior have grown more complicated.
“Ultimately I don’t think that things being complicated is a problem in geoscience,” Elizabeth Day, a geophysicist at Imperial College London, said in an email. “We know the surface of our planet is complex … so it is reasonable to assume the deep interior is also complicated! To definitely say how the inner core is rotating relative to the outer layers of the planet, we will need to keep collecting as much data as we can.”
The stakes of this scientific debate are high in part because the core is a mystery that lurks, unsolved, so tantalizingly close to home.
“This is not something that’s going to affect the price of potatoes tomorrow,” Richards said. But the debate speaks to more-profound questions about Earth’s formation and how its inner layers support life on its surface, something that may aid studies of habitability on rocky planets circling other stars.
“When you think … what our planet consists of and what its history is,” Richards said, “a deep understanding of the inner core gets you into ‘How did all these divisions of planet Earth evolve?’”
Traveling Back in Time Is Possible Inside Universes That Spin : ScienceAlert
It turns out that time travel into the past is actually relatively easy. All you need to do is make the universe rotate.
The famous mathematician Kurt Gödel was a friend and neighbor of Albert Einstein at Princeton. He became incredibly curious about Einstein’s general theory of relativity, which was and continues to be our modern formulation of the gravitational force.
That theory connects the presence of matter and energy to the bending and warping of space and time, and then connects that bending and warping to the behavior of matter and energy.
Gödel was curious as to whether relativity could allow time travel into the past. Einstein’s theory purported to be an ultimate framework for the nature of space and time, and as far as we know time travel into the past is forbidden. So Gödel reckoned that general relativity should automatically disallow it.
And Gödel discovered that actually general relativity is perfectly fine with time travel into the past. The trick is to set the universe in motion.
Gödel constructed a relatively simple and artificial model universe to prove his point. This universe is rotating and contains only one ingredient. That ingredient is a negative cosmological constant that resists the centrifugal force of the rotation to keep the universe static.
Gödel found that if you follow a particular path in this rotating universe you can end up in your own past. You would have to travel incredibly far, billions of light years long, to do it, but it can be done.
As you travel, you would get caught up in the rotation of the universe. That isn’t just a rotation of the stuff in the cosmos, but of both space and time themselves. In essence, the rotation of the universe would so strongly alter your potential paths forward that those paths loop back around to where you started.
You would set off on your journey and never travel faster than the speed of light, and you would find yourself back where you started but in your own past.
The possibility of backwards time travel creates paradoxes and violates our understanding of causality. Thankfully, all observations indicate that the universe is not rotating, so we are protected from Gödel’s problem of backwards time travel.
But it remains to this day a mystery why General Relativity is okay with this seemingly impossible phenomenon. Gödel used the example of the rotating universe to argue that General Relativity is incomplete, and he may yet be right.

Biden granddaughter’s wedding offers youthful spin for president turning 80
CNN
—
President Joe Biden is turning 80 this weekend, but the big bash at the White House will be for an entirely different and more youthful occasion. Naomi Biden, Biden’s oldest granddaughter, is set to marry Peter Neal on the White House South Lawn on Saturday.
One day following the nuptials, Biden will mark his spot in American history as the only octogenarian president, a numerical milestone that shines a spotlight on a primary issue plaguing Biden with his opponents: his age. Despite a spate of recent wins – better-than-projected midterm elections for Democrats, a relatively gaffe-less trip to Egypt and Asia, and a lackluster presidential announcement from his old rival, Donald Trump – Biden cannot shake being the oldest commander-in-chief America has ever had.
But a glossy wedding of two twenty-somethings, kicking off a fresh life chapter with music and dancing and revelry, could put a youthful spin on the 80th birthday weekend. Two people familiar with the planning of the wedding say it was not a coincidence Naomi Biden’s wedding weekend coincides with the president’s day – noting the “age issue” is never something Biden wants to highlight.
“The wedding gives some cover,” says one of the people.
The wedding, which CNN is told includes the extended Biden clan on the guest list, as well as friends and family of the couple, will also mark a kickoff of sorts for the tight-knit Bidens to begin earnest discussions over whether Joe Biden should run for a second term.
Shortly after the wedding, Jill Biden and Joe Biden will travel to Nantucket, Massachusetts, for the Thanksgiving holiday; Christmas follows quickly on its heels, as the clock ticks toward Biden’s need to say whether he will be in for 2024, or out. Both the president and the first lady have said they will weigh the pros and cons of a second run, something Biden has previously said he “intends” to undertake.
The wedding itself will consist of three parts, a person familiar with the planning tells CNN. The ceremony will take place at 11 a.m. ET on the South Lawn – a location that in the history of White House weddings has never before been used. There will be no tent, the source confirms, which could make for a chilly outdoor morning; temperatures for Saturday are forecast in the mid-40s. Following the exchange of vows, a smaller, family-and-wedding-party-only luncheon will take place in the White House, and later, in the evening, guests will return for an evening reception of dessert and dancing, also to be held indoors.
In a way, Naomi Biden, 28, is experiencing a White House wedding thanks in large part to her own gumption. Biden, an associate at the Washington, DC, law firm Arnold & Porter, pushed her grandfather to run the first time.
Though the patriarch, Joe Biden has always included his larger family circle, including his five oldest grandchildren when weighing life choices. His sensitivity to their feelings, and the invasive nature of a nasty political battle weigh heavy on his mind.
“I don’t think there’s been any decision, no matter how big or small, that we haven’t decided as a family,” said Naomi Biden in a video interview played at the 2020 Democratic National Convention.
Though typically called by the elder Biden family members, it was Naomi Biden who convened the most critical, in-person, all-hands-on-deck family meeting, the one that would have the most impact on Joe Biden’s future. Biden was concerned – they, however, were not.
“He thought we were calling a meeting sort of to discuss whether or not we wanted him to [run,] but really were calling it to be like, ‘Get in that race! Hurry up!’” said Naomi Biden. In the years since, it has been Naomi who has been most publicly vocal on her social media channels about Democratic issues, and championing her grandfather. On November 12, she tweeted, “Democracy wins in the Senate. Never think your vote doesn’t matter.”
Naomi is also the grandchild closest – literally – to her grandparents. She and Neal, 25, a recent University of Pennsylvania Law School graduate who works at Georgetown University Law Center on National Security, moved into the White House last August, a person familiar with the living arrangements tells CNN.
The close proximity to the couple’s wedding site has only increased their involvement in the planning. The wedding planner is Bryan Rafanelli, founder of Rafanelli Events, the source familiar with the details tells CNN. Rafanelli is no stranger to whipping up fantastical parties at the White House; he oversaw seven State Dinners during Barack Obama’s presidency, including the final of the administration for Italy, which included a tent with a glass ceiling on the South Lawn and a performance by Gwen Stefani.
He also planned and orchestrated the wedding of Chelsea Clinton in 2010.
A Rafanelli-produced wedding is not an inexpensive endeavor. The price tag for many of his events starts at around $300,000 and can go into the millions of dollars. “Consistent with other private events hosted by the First Family and following the traditions of previous White House wedding festivities in prior Administrations, the Biden family will be paying for the wedding activities that occur at the White House,” Jill Biden’s communications director Elizabeth Alexander told CNN.
Naomi’s father is Hunter Biden. Her mother is Kathleen Buhle. Her parents, who divorced in 2017, have each written memoirs about struggles in their relationship, many of which involved Hunter Biden’s yearslong struggle with addiction.
Neal’s family is from Jackson Hole, Wyoming, where the couple was engaged in September 2021. (The engagement ring includes the band of Neal’s grandmother’s engagement ring and was designed by a DC jeweler, a person with knowledge of its construction tells CNN.)
Naomi Biden’s wedding gown designer has not yet been revealed, though several fashion insiders contacted by CNN speculate the job went to Ralph Lauren, perhaps the most iconic American fashion designer alive today. Joe Biden is partial to Lauren’s suits, having worn one on Inauguration Day, and Jill Biden has also been photographed wearing the label. In March, Naomi and her sister, Finnegan, 23, and Neal, attended Ralph Lauren’s Fall 2022 fashion show in New York City, which sparked most of the chatter that she will wear the designer for at least one of her wedding looks. The White House did not comment on the dress speculation.
Photographs of the wedding are set to be released to the press on Saturday afternoon, at some point between the morning ceremony and the evening reception, the person familiar with the planning says.
Without question, the wedding will be the social event of the White House this year, perhaps of the entire Biden administration. It is only the 19th wedding to ever take place at the White House, the last one was for Obama’s chief photographer, Pete Souza, who in 2013 was married in the Rose Garden. The last presidential daughter to celebrate a wedding at the White House was Jenna Bush in June 2008. Bush held her wedding and reception months prior at the Bush family’s Texas ranch, but her father, George W. Bush, hosted approximately 600 guests at the White House for his daughter’s second reception.
But the scope and scale of the Biden wedding most correlates with that of Luci Johnson, who held her reception in the East Room after marrying Patrick Nugent, and Lynda Johnson, who in 1967 married Charles Robb in the East Room of the White House. Tricia Nixon in June 1971 married Edward Finch Cox under a flower-laden white gazebo erected in the Rose Garden. All of these weddings were media catnip, with newspapers printing the recipes for the 6-feet tall wedding cakes.
Pieces of the Johnson daughters’ and Nixon’s cakes were sent to the Smithsonian National Museum of American History. (Nixon’s hardened to a 2-inch by 2-inch piece that now looks like a dried sponge, according to the White House Historical Association.)
No word yet on Biden’s cake flavor, or whether like the aforementioned White House weddings, guests will take home a slice as a party favor at the end of the evening.
Rihanna x Johnny Depp collab sends internet into a spin: ‘This is epic’
Johnny Depp has seemingly gone from zero to hero in the pop culture stakes, with one of the biggest music stars in the world set to feature him in her new show.
Sources have told TMZ that Depp will make a guest appearance in Rihanna’s upcoming Savage X Fenty Vol. 4 fashion show.

No, he won’t be walking the runway in a choice bit of loungewear.
Instead, he will appear in a pre-filmed “star” moment – the first male to take the role in the history of the fashion shows, which have previously featured the likes of Cindy Crawford and Erykah Badu.
Depp has already filmed his cameo moment, TMZ reports.
Sources told the outlet Depp’s style in the video is “cool and chic”, as befits his trademark rock and roll style.
Depp and Rihanna fans went wild when the news was announced by TMZ on social media.
“OMG I love this,” one fan wrote.
“I almost dropped my phone – this is epic,” said another.
“YESSSS YES YES YES JONNY X RIHANNA,” another enthused.
“Ooooh, this should be fun!” another remarked.
Bizarre appearance
It remains to be seen whether Depp’s appearance in Rihanna’s fashion show will be a hit or a miss.
He recently made a rather bizarre “cameo” appearance at the MTV Video Music Awards, appearing as a floating astronaut hovering above the crowd.
The actor and musician’s face was digitally imposed inside the helmet of a space man, the inspiration for the VMAs Moon Person statue, and he delivered brief jokes throughout the live ceremony.
“I needed the work,” the Pirates of the Caribbean star joked at the start of the show, held in August.
Later in the ceremony, Depp said he was available for “birthdays, bar mitzvahs, bat mitzvahs, weddings, wakes, any old thing you need.”
In June this year, Depp won a near-total victory in his legal battle with ex-wife Amber Heard, who had accused him of physical abuse.
Depp denied hitting her or any other woman.
Two years earlier, Depp lost a libel suit in Britain against the Sun tabloid, which called him a “wife beater”.
A London High Court judge ruled Depp had repeatedly assaulted Heard.
He was soon dropped from Harry Potter spin-off franchise Fantastic Beasts and largely shunned by Hollywood.
Revived career
However, since his US court victory, Depp’s career has started to revive itself.
He has performed music on tour with Jeff Beck and is set to direct Modigliani, a biographical drama about Italian artist Amedeo Modigliani.
The actor also is set to play King Louis XV in French film Jeanne du Barry, and his lucrative contract for the Dior fragrance Sauvage has also been renewed.
