Physicists Move One Step Closer to a Theoretical Showdown
The deviance of a tiny particle called the muon might prove that one of the most well-tested theories in physics is incomplete.

On July 24, a large team of researchers convened in Liverpool to unveil a single number related to the behavior of the muon, a subatomic particle that might open a portal to a new physics of our universe.
All eyes were on a computer screen as someone typed in a secret code to release the results. The first number that popped out was met with exasperation: a lot of concerning gasps, oh-my-God’s and what-did-we-do-wrong’s. But after a final calculation, “there was a collective exhale across multiple continents,” said Kevin Pitts, a physicist at Virginia Tech who was five hours away, attending the meeting virtually. The new measurement matched exactly what the physicists had computed two years prior — now with twice the precision.
So comes the latest result from the Muon g-2 Collaboration, which runs an experiment at Fermi National Accelerator Laboratory, or Fermilab, in Batavia, Ill., to study the deviant motion of the muon. The measurement, announced to the public and submitted to the journal Physical Review Letters on Thursday morning, brings physicists one step closer to figuring out if there are more types of matter and energy composing the universe than have been accounted for.
“It really all comes down to that single number,” said Hannah Binney, a physicist at the Massachusetts Institute of Technology’s Lincoln Laboratory who worked on the muon measurement as a graduate student.
Scientists are putting to the test the Standard Model, a grand theory that encompasses all of nature’s known particles and forces. Although the Standard Model has successfully predicted the outcome of countless experiments, physicists have long had a hunch that its framework is incomplete. The theory fails to account for gravity, and it also can’t explain dark matter (the glue holding our universe together), or dark energy (the force pulling it apart).
One of many ways that researchers are looking for physics beyond the Standard Model is by studying muons. As heavier cousins of the electron, muons are unstable, surviving just two-millionths of a second before decaying into lighter particles. They also act like tiny bar magnets: Place a muon in a magnetic field, and it will wobble around like a top. The speed of that motion depends on a property of the muon called the magnetic moment, which physicists abbreviate as g.
In theory, g should exactly equal 2. But physicists know that this value gets ruffled by the “quantum foam” of virtual particles that blip in and out of existence and prevent empty space from being truly empty. These transient particles change the rate of the muon’s wobble. By taking stock of all the forces and particles in the Standard Model, physicists can predict how much g will be offset. They call this deviation g-2.
But if there are unknown particles at play, experimental measurements of g will not match this prediction. “And that’s what makes the muon so exciting to study,” Dr. Binney said. “It’s sensitive to all of the particles that exist, even the ones that we don’t know about yet.” Any difference between theory and experiment, she added, means new physics is on the horizon.
To measure g-2, researchers at Fermilab generated a beam of muons and steered it into a 50-foot-diameter, doughnut-shaped magnet, the inside brimming with virtual particles that were popping into reality. As the muons raced around the ring, detectors along its edge recorded how fast they were wobbling.
Using 40 billion muons — five times as much data as the researchers had in 2021 — the team measured g-2 to be 0.00233184110, a one-tenth of 1 percent deviation from 2. The result has a precision of 0.2 parts per million. That’s like measuring the distance between New York City and Chicago with an uncertainty of only 10 inches, Dr. Pitts said.
“It’s an amazing achievement,” said Alex Keshavarzi, a physicist at the University of Manchester and a member of the Muon g-2 Collaboration. “This is the world’s most precise measurement ever made at a particle accelerator.” The results, when revealed to the public at a scientific seminar on Thursday morning, were met with applause.
“The kind of precision that these people have managed to attain is just staggering,” said Dan Hooper, a theoretical cosmologist at the University of Chicago who was not involved in the work. “There was a lot of skepticism they would get here, but here they are.”
But whether the measured g-2 matches the Standard Model’s prediction has yet to be determined. That’s because theoretical physicists have two methods of computing g-2, based on different ways of accounting for the strong force, which binds together protons and neutrons inside a nucleus.
The traditional calculation relies on 40 years of strong-force measurements taken by experiments around the world. But with this approach, the g-2 prediction is only as good as the data that are used, said Aida El-Khadra, a theoretical physicist at the University of Illinois Urbana-Champaign and a chair of the Muon g-2 Theory Initiative. Experimental limitations in that data, she said, can make this prediction less precise.
A newer technique called a lattice calculation, which uses supercomputers to model the universe as a four-dimensional grid of space-time points, has also emerged. This method does not make use of data at all, Dr. El-Khadra said. There’s just one problem: It generates a g-2 prediction that differs from the traditional approach.
“No one knows why these two are different,” Dr. Keshavarzi said. “They should be exactly the same.”
Compared with the traditional prediction, the latest g-2 measurement has a discrepancy of over 5-sigma, which corresponds to a one in 3.5 million chance that the result is a fluke, Dr. Keshavarzi said, adding that this degree of certainty was beyond the level needed to claim a discovery. (That’s an improvement from their 4.2-sigma result in 2021, and a 3.7-sigma measurement done at Brookhaven National Laboratory near the turn of the century.)
But when they compared it with the lattice prediction, Dr. Keshavarzi said, there was no discrepancy at all.
Rarely in physics does an experiment surpass the theory, but this is one of those times, Dr. Pitts said. “The attention is on the theoretical community,” he added. “The limelight is now on them.”
Dr. Binney said, “We are on the edge of our seats to see how this theory discussion pans out.” Physicists expect to better understand the g-2 prediction by 2025.
Gordan Krnjaic, a theoretical particle physicist at Fermilab, noted that if the experimental disagreement with theory persisted, it would be “the first smoking-gun laboratory evidence of new physics,” he said. “And it might well be the first time that we’ve broken the Standard Model.”
While the two camps of theory hash it out, experimentalists will hone their g-2 measurement further. They have more than double the amount of data left to sift through, and once that’s included, their precision will improve by another factor of two. “The future is very bright,” said Graziano Venanzoni, a physicist at the University of Liverpool and one leader of the Muon g-2 experiment, at a public news briefing about the results.
The latest result moves physicists one step closer to a Standard Model showdown. But even if new physics is confirmed to be out there, more work will be needed to figure out what that actually is. The discovery that the known laws of nature are incomplete would lay the foundation for a new generation of experiments, Dr. Keshavarzi said, because it would tell physicists where to look.
“Physicists get really excited when theory and experiment do not agree with each other,” said Elena Pinetti, a theoretical physicist at Fermilab who was not involved in the work. “That’s when we really can learn something new.”
For Dr. Pitts, who has spent nearly 30 years pushing the bounds of the Standard Model, proof of new physics would be both a celebratory milestone and a reminder of all that is left to do. “On one hand it’s going to be, Have a toast and celebrate a success, a real breakthrough,” he said. “But then it’s going to be back to work. What are the next ideas that we can get to work on?”

NASA Seeks a Nuclear-Powered Rocket to Get to Mars in Half the Time
By Kenneth Chang
Published July 26, 2023Updated July 27, 2023
In less than four years, NASA could be testing a nuclear rocket in space.
The space agency and the Defense Advanced Research Projects Agency, or DARPA, announced on Wednesday that Lockheed Martin had been selected to design, build and test a propulsion system that could one day speed astronauts on a trip to Mars.
BWX Technologies, based in Lynchburg, Va., will build the nuclear fission reactor at the heart of the engine.
The $499 million program is named DRACO, short for the Demonstration Rocket for Agile Cislunar Operations.

What if a spacecraft could get to Mars in half the time it currently takes?
Every 26 months or so, Mars and Earth are close enough for a shorter journey between the worlds. But even then it is a pretty long trip, lasting seven to nine months. For most of the time, the spacecraft is just coasting through space.
But if the spacecraft could continue accelerating through the first half of the journey and then start slowing down again, the travel time could be slashed. Current rocket engines, which typically rely on the combustion of a fuel like hydrogen or methane with oxygen, are not efficient enough to accomplish that; there is not enough room in the spacecraft to carry that much propellant.
But nuclear reactions, generating energy from the splitting of uranium atoms, are much more efficient.
The DRACO engine would consist of a nuclear reactor that would heat hydrogen from a chilly minus 420 degrees Fahrenheit to a toasty 4,400 degrees, with the hot gas shooting from a nozzle to generate thrust. Greater fuel efficiency could speed up journeys to Mars, reducing the amount of time astronauts spend exposed to the treacherous environment of deep space.
Nuclear propulsion could also have uses closer to home, which is why DARPA is investing in the project. The technology may allow rapid maneuvers of military satellites in orbit around Earth.
Nuclear propulsion for space is not a new idea. In the 1950s and 1960s, Project Orion — financed by NASA, the Air Force and the Advanced Research Projects Agency — contemplated using the explosions of atomic bombs to accelerate spacecraft.
At the same time, NASA and other agencies also undertook Project Rover and Project NERVA, efforts that aimed to develop nuclear-thermal engines similar in concept to those now being pursued by the DRACO program. A series of 23 reactors were built and tested, but none were ever launched to space. Until the end of this program in 1973, NASA had contemplated using nuclear reactors to propel space probes to Jupiter, Saturn and beyond, as well as to provide power at a lunar base.
“The technical capabilities, including early safety protocols, remain viable today,” Tabitha Dodson, the DRACO project manager, said in a news briefing on Wednesday.
A key difference between NERVA and DRACO is that NERVA used weapons-grade uranium for its reactors, while DRACO will use a less-enriched form of uranium.
The reactor would not be turned on until it reached space, part of the precautions to minimize the possibility of a radioactive accident on Earth.
“DRACO has already done all of our preliminary analyses across the entire spectrum of possibilities for accidents and found that we’re all the way down in the low probability and all the way down in the teeny tiny amount of release,” Dr. Dodson said.
The DRACO development is to culminate with a flight test of the nuclear-thermal engine. The launch is currently scheduled for late 2026 or early 2027.
The demonstration spacecraft would most likely orbit at an altitude between 435 and 1,240 miles, Dr. Dodson said. That is high enough to ensure that it stays in orbit for more than 300 years, or long enough for radioactive elements in the reactor fuel to decay to safe levels, she said.
A correction was made on
July 28, 2023
:
Using information from a news conference, an earlier version of this article misstated when a flight test of a nuclear-thermal engine could occur. The launch is scheduled for late 2026 or early 2027, not late 2025 or early 2026.

Response and Articles 12/19/2023
At the end of the war between the states: louisiana, south carolina, mississippi had majority black populaces, but the governments of said states had no black officials. One of the problems with some Black people in the usa is they speak very neutrally when it comes to humanity. Being verbose is a long thing, can be fatiguging, but is usually more descriptive and being more descriptive is needed when you speak of the past in humanity anywhere. The palestinean people had the majority in palestine when the zionist came but the government was completely run by members of the british empire. so...
I think a valid question exist. Beyond the law, did the 14th or 15th amendment's make the Black Enslaved or former enslaved citizens? What makes a citizen? is it the law? or is it, the communal context? I argue the history of the native american in the usa+ the black enslaved or descended of enslaved in the usa, refutes the idea that citizenry comes from the law.
The authors states tremendous progress for the black populace in what is commonly callted reconstruction in the usa, but i argue that is erroneous. First, most black people in the usa, 90% were still financially dead, no savings, no money, no land, n opportunity to gain financially. Tremendous progress I thought represented a lifting of a majority in a populace, not a financial stagnation from a majority that never had financial betterment.
The biggest problem with Black people in the usa, is the lie we tell ourselves about the commonly called Great Migration, which I call the Black fleeing. Black people flew from the south cause black people were being killed/murdered/incarcerated absent criminal activity/assaulted through the entirey of reconstruction, ask Ida B Wells and flew to the northern cities to be treated better. Most black people did not think they were going to financial betterment outside the south. I wonder where that myth comes from. Yes, some black people sought financial betterment but most wanted away from whitey.The firs thing he said that is truth, Black people always flew back to the south. But the reason was always simple. Thew white governments of the exosouth [north or west] was no better than the white governments of the south. Remember, Tulsa, which wasn't majority black like NYC, Chicago, Los ANgeles, had a government that aided in the bombing and looting of the black community in tulsa by the white community. To be blunt, NYC, Chicago, Los ANgeles were not haven cities for blacks, that is a myth. But the fact that they were not is why black people flew back.
Now what is missing. Many years ago, during Obama's first campaign I suggested Black people in the usa needed a black party of governance in the usa to focus on places where the populace of black people is largest. He speaks of Black Power in government locally in the southern states but doesn't suggest a black party of governance in said states? why? I always find it strategically silly that any community is unwilling to support organizations strictly to their benefit when they have numerical advantage.
Why do the black towns and counties of the south have representatives of andrew jackson or abraham lincoln when both have proven to be useless in being effective to making or administering legal policy to Black benefit.I emailed him my thoughts, you can do the same

This photo is part of the problem. Most black people didn't own a car. This black family is financially the black one percent. This black family is looking for financial betterment but most black people owned nothing. I know for certain. Most Black people fled the south , walking, taking the train, fleeing white violence. But the narrative whites like to hear, ala magical negro is it was a simple financial move.
Charles M. Blow on reversing the Great Migration
sunday-morning
BY CHARLES M. BLOWDECEMBER 17, 2023 / 10:25 AM EST / CBS NEWS
Our commentary is from New York Times columnist Charles M. Blow, whose new HBO documentary "South to Black Power" is now streaming on Max:At the end of the Civil War, three Southern states (Louisiana, South Carolina and Mississippi) were majority Black, and others were very close to being so. And during Reconstruction, the 14th and 15th Amendments to the Constitution made Black people citizens and gave Black men the right to vote.
This led to years of tremendous progress for Black people, in part because of the political power they could now access and wield on the state level.
But when Reconstruction was allowed to fail and Jim Crow was allowed to rise, that power was stymied. So began more decades of brutal oppression.In the early 1910s, Black people began to flee the South for more economic opportunity and the possibility of more social and political inclusion in cities to the North and West. This became known as the Great Migration, and lasted until 1970.
But nearly as soon as that Great Migration ended, a reverse migration of Black people back to the South began, and that reverse migration – while nowhere near as robust of the original – is still happening today.
In 2001 I published a book called "The Devil You Know," encouraging even more Black people to join this reverse migration and reclaim the state power that Black people had during Reconstruction. I joined that reverse migration myself, moving from Brooklyn to Atlanta.
Last year, I set out to make a documentary which road-tested the idea, traveling the country, both North and South, and having people wrestle with this idea of Black power.
Here are three things I learned from that experience.
First, Black people are tired of marching and appealing for the existing power structure to treat them fairly.
Second, young Black voters respond to a power message more than to a message of fear and guilt.
And third, many of the people I talked to had never truly allowed themselves to consider that there was another path to power that didn't run though other people's remorse, pity, or sense of righteousness.
I don't know if Black people will heed my call and reestablish their majorities, or near-majorities, in Southern states. But sparking the conversation about the revolutionary possibility of doing so could change the entire conversation about power in this country, in the same way that it has changed me.

Alabama
Black Descendent of enslaved leaders guided the majority populace of said people to do what Maher says the palestinean should do. Based on the history of said people my advice is for the palestinean to keep fighting for the river to the sea. Yes, it may lead to a termination of palestineans. But, look at the native american in the usa. Look at the black descended of enslaved in the usa.
Two peoples who in overwhelming majority, not all, chose the path Maher suggest the palestinean choose. What did it lead to?
Whites in the USA got what they wanted, they got to win a blood feud absent having to kill the rivals in the feud, and then use that as a symbol of usa greatness. The black descended of enslaved plus native american became idolters, mostly ranked by people who are completely infatuated to the culture of those who enslaved them, completely impotent populaces concerning what can only come from collective force, beggers or crawlers in the system designed by rivals in a blood feud.
Maher is correct, as someone in this community said to me the same as other black people said many times in earshot in my offline life, the past can not be changed. But, how you plan for the future does not have to suggest the past didn't happen. And that is what Maher truly wants, what the native american of the usa did, what the black descended of the usa did, for the palestinean people to eat the crow of accepting the system of their opposer and embrace said system. Then they can have a palestinean president of israel. They can have dancing jolly musicals about the fiscally poor palestineans abused by the tyrranical israelis hurting each other for relief. They can mate with israelis and have a bunch of loving palestinean-israeli mulattoes. Yeah, I know what Maher is suggesting to the palestinean. If the palestinean is wise,better for the community to die than to become the native american of the usa.Maher on palestineans
Maher on netanyahu
IN AMENDMENT
The problem with netanyahu is like so many , he is unwilling to embrace the truth of his country,this is what hitler did that many leaders are unwilling to do. Embrace the power and violence of their government as power+ violence. The Statian empire teaches all governments that power must always be wielded as benevolence, this comes from the british imperial tradition that create the usa. But I oppose that, if you are a bully be a bully. You want to push the palestineans out, then simply do it. Trying to suggest you are legal or pure or a good person or some other thing to make a false narrative in a history book or to assuade your descendents of how they got their wealth is to me a true sin. Maher says Israel is powerful , well it is time for israel to embrace that position. And to embrace that the zionist chose this location. If the zionist were wise they would had chosen somewhere in europe but they were not, they assumed they could chose a muslim place and convert it through influence of their big brother who was started the same way, the usa. But they underestimated that not all peoples are the native american + black descended of enslaved who are weak peoples. So the zionist made the bed, the israeli has to live in it, israel will always be the enemy of its neighbors, that is the zionist legacy, netanyahu needs to embrace it and kick the palestinean out and live surrounded by enemies.
What DAvid Alan Grier said is correct, and in the situation of candy cane lane holds truth but the reason it isn't industry wide must be discussed. The problem with the narrative is, who owns is irrelevant . Grier says all need to see themselves, and he isn't wrong but black people don't see themselves in media in the usa cause black people don't own the media. Many black people in the usa seem to think not owning sports team, not owning film studios, not owning music labels, not owning car companies, not owning gun manufacturers, not owning cement makers, not owning real estate , not owning mass produce producers[corporate farms], is not a factor. Black people in the usa don't own any industry. That is why Black people are not present as we will like in any industry in the usa. IT is very simple. But the reason black people don't own is because of our history under this government , historically white, that placed us in a negative financial state where whites disallowed us from owning. Yes, starting in the 1980s, it can be said that the black populace in the usa finally was free from the yoke of the whites to grow as individuals BUT it matters when whites in the usa have opportunities to take native american land, when whites have the opportunity to rip natural resources from the earth, when whites have the opportunity to have a gilded age making fortunes for bloodlines off of acts today deemed illegal. MErit isn't unimportant. I am not knocking down merit. But merit isn't more important than opportunity but opportunity in the usa comes from ownership not merit. And ownership in the USA 99% of the time comes from advantage through an ancestor using arms, guns, or inheriting wealth from an ancestor who used arms, guns.
...
This situation reflects my point, ownership is more important than merit or equality. eddie mruphy is an owner/a producer and makes the choices, if eddie murphy didn't put grier or someone black as santa that is his choice. My point is ownership is superior to merit. Black culture/storytelling has always been present to support black people feeling apart of anything. And I know cause growing up as a kid I never felt deprived of black presence in media or in any season cause of my parents.David Alan Grier on Why His Surprise Cameo as Black Santa in ‘Candy Cane Lane’ Reminded Him of ‘Black Panther’
The film reunited him with his 'Boomerang' collaborators Eddie Murphy and director Reginald Hudlin.
BY CHRIS GARDNERPlus Icon
DECEMBER 9, 2023 11:15AMAs the Candy Cane Lane premiere red carpet heated up Nov. 28, two publicist elves worked their way down the press line to remind journalists not to spoil the big reveal from the Reginald Hudlin-directed holiday adventure.
The Prime Video release, penned by Kelly Younger, stars Eddie Murphy as a recently unemployed man on a mission to win his neighborhood’s annual Christmas home decoration contest. The hush-hush surprise happens late in the film when David Alan Grier crash-lands in an ultra-slick sleigh as (the lifted embargo permits us to announce) Black Santa Claus.
“Reggie called and told me what his idea was and I was overjoyed, man. He let me flow and egged me and Eddie on,” explained Grier of reteaming with Hudlin and Murphy with whom he teamed for the 1992 romantic comedy Boomerang. “That was over 30 years ago and all we talked about were cars, clubs, big houses, like ‘Where y’all going tonight.’ This was different because Eddie is so chill. He has kids, grandkids. He seemed really, really happy.”
As far as the significance of playing an iconic character as a Black man, Grier said the opportunity reminded him of Black Panther. “When you see yourself represented in movies or stories, it’s an affirmation that you exist, that you belong, and that you’re legitimate. That’s what people forget about to see ourselves, not just us, everybody. There’s room for all of us at the table. This is the first Christmas movie I ever did so it’s got to last a long time.”
Who knows, there may also be a sequel. Prime Video announced last week that following its debut, Candy Cane Lane quickly became the No. 1 movie worldwide on Prime Video, the most-watched am*zon MGM Studios-produced movie debut ever in the U.S. and among the top 10 worldwide film debuts ever on the service.
“The sensational debut of Eddie Murphy’s first-ever Christmas movie, Candy Cane Lane, is a true demonstration of how joyful, family-oriented stories can touch the hearts of viewers around the world,” offered Courtenay Valenti, head of film, streaming, and theatrical at am*zon MGM Studios.
Grier is also counting his blessings this holiday season. “I’m going to tell you right now, I’m 67 years old. I did not think that my career would be here at my age. I have more work than I can even say yes to. My career is booming and I feel like I finally figured out what I’m doing, so I’m only getting better and better. We’ll see what happens.”

Google's New AI Text-to-Video Tool Is Fun to Look At. But What Next?
Story by Lisa Lacy • 38m
Google has teased an AI-based video generation tool, but it's not clear when — or if — anyone outside the search giant will be able to kick the tires. It's certainly fun to look at, though.
On Wednesday, Google's Research arm released a video highlighting this new text-to-video model, which is called Lumiere.
In a LinkedIn post, team leader Inbar Mosseri said the tool "generates coherent, high-quality videos using simple text prompts" that New Atlas says run up to five seconds. Sample inputs include, "A fluffy baby sloth with an orange knitted hat trying to figure out a laptop" and "An escaped panda eating popcorn in the park."
In the year or so that generative AI has been the hottest technology going, much of the attention has been focused on tools like ChatGPT that produce text answers to prompts, or those like Dall-E that create still images. Video creation from text prompts is arguably the next frontier, so if Lumiere really can "demonstrate state-of-the-art text-to-video generation results" as Google says, we may already be evolving beyond the "grotesque abominations" of the AI-generated images of 2023.
As the video illustrates, Lumiere's capabilities include text-to-video and image-to-video generation, as well as stylized generation — that is, using an image to create videos in a similar style. Other tricks include the ability to fill in any missing visuals within a video clip.
That includes the ability to animate famous paintings, like Van Gogh's Starry Night ("A timelapse oil painting of a starry night with clouds moving") or Da Vinci's Mona Lisa ("A woman looking tired and yawning"). While the Starry Night example works almost flawlessly, Mona Lisa looks far more like she's laughing than yawning.
And while many of the animals — such as "a muskox grazing on beautiful wildflowers" and "a happy elephant wearing a birthday hat walking under the sea" — look realistic, there's something off about some of the dogs. Both a toy poodle riding a skateboard and a golden retriever puppy running in the park are close to passing as real, but their faces — and perhaps their eyes specifically—betray the fact that they're CGI.
Nevertheless, the video editing tools hold a lot of promise. Using a source video and prompts like "made of colorful toy bricks" or "made of flowers," users can purportedly change the style of the subject completely. And with inputs like "wearing a bathrobe," "wearing a party hat" and "wearing rain boots" to add said items to an image of, say, a baby chick, Lumiere may very well make fiddling with videos more accessible to those of us who didn't major in graphic design.
Though the assets shared so far certainly make Lumiere seem like it's user-friendly, the description of how it works isn't. (Google didn't respond to a request for additional comment.)
A project page < https://lumiere-video.github.io/ > describes Lumiere as "a space-time diffusion model," which sounds like something Doc Brown was working on in Back to the Future. Google Research said this means the text-to-image model learns to generate a video by processing it in multiple space-time scales, which helps create videos that "portray realistic, diverse and coherent motion."
According to Google, this is superior to existing models, which "synthesize distant keyframes followed by temporal super-resolution."
Jason Alan Snyder, global chief technology officer at ad agency Momentum Worldwide, explained it this way: "It's like the difference between watching a puppet show and experiencing a ballet at Lincoln Center."
That's because Lumiere "doesn't just focus on snapshots, it crafts smooth, flowing motion for every frame," he added.
In other words, if you think about the traditional method of making a movie, you'd have to build key scenes and fill in the gaps later.
"Lumiere is different. It sees the whole movie in its mind, understanding how characters move, objects interact and everything changes over time," Snyder said. "It's like drawing the entire flip book simultaneously, ensuring every page flows perfectly."
So this "space-time thinking" helps Lumiere create videos that feel real, which, he added, means no more jumpy transitions or robotic movements. (Except maybe for puppy eyes.)
Time will tell.
In the meantime, as fans of Beauty and Beast will know, Lumiere is French for "light."

Man cleared in a 1996 Brooklyn killing said for decades he knew who did it. Prosecutors now agree
By Associated Press New York State

NEW YORK (AP) — A man who served 14 years in prison for a deadly 1990s shooting was exonerated Thursday after prosecutors said they now believe the killer was an acquaintance he has implicated for decades.
“I lost 14 years of my life for a crime that I didn’t commit,” Steven Ruffin told a Brooklyn judge after sighing with emotion.
Although Ruffin was paroled in 2010 and has since built a career in sanitation in Georgia, he said that getting his manslaughter conviction dismissed and his name cleared “will help me move on.”
“If you know you're innocent, don’t give up on your case — keep on fighting, because justice will prevail,” Ruffin, 45, said outside court. “That’s all I’ve wanted for 30 years: somebody to listen and really hear what I’m saying and look into the things I was telling them."
Prosecutors said they were exploring whether to charge the man they now believe shot 16-year-old James Deligny on a Brooklyn street during a February 1996 confrontation over some stolen earrings. Brooklyn District Attorney Eric Gonzalez said after court that charges, if any, wouldn't come immediately.
“You have to be able to convict someone beyond a reasonable doubt, and we have to make sure that that evidence is sufficient to do so,” said Gonzalez, who wasn't DA when Ruffin was tried. “You have a lot of factors working against us procedurally, but also factually — unfortunately, this is 30 years ago.”
Ruffin's conviction is the latest of more than three dozen that Brooklyn prosecutors have disavowed after reinvestigations over the last decade.
Over a dozen, including Ruffin's, were connected to retired Detective Louis Scarcella. He was lauded in the 1980s and ‘90s for his case-closing prowess, but defendants have accused him of coercing confessions, engineering dubious witness identifications and other troubling tactics. He has denied any wrongdoing.
Prosecutors said in their report on the Ruffin case that they “did not discover any misconduct by Scarcella" in the matter. A message seeking comment was sent to his attorney.
Prosecutors said the police investigation — and their office's own at the time — “were wholly inadequate” and tunnel-visioned, failing to look into the person they now believe was the gunman.
The mistaken-identity shooting happened as Ruffin and others were looking for a robber who had just snatched earrings from Ruffin’s sister. In fact, Deligny wasn't the robber, authorities say.
Tipsters led police to Ruffin, then a 17-year-old high school student, and the victim's sister identified him in a lineup that a court later deemed flawed. Scarcella wasn't involved in the lineup, but he and another detective questioned Ruffin.
The teen told them, twice, that he saw but wasn't involved in Deligny's shooting, according to police records quoted in prosecutors' report.
Then Scarcella brought the teen's estranged father — a police officer himself — to the precinct. The father later testified that he told his son to “tell the truth,” but Ruffin said his father leaned on him to confess.
And he did confess, saying he fired because he thought Deligny was about to pull something out of his jacket. Ruffin told the detectives they could retrieve the gun from his sister's boyfriend, and they did, prosecutors' report said.
Ruffin quickly recanted to his father, who didn't tell the detectives his son had taken back his confession, according to prosecutors' report. The teen went on to testify at his trial that he didn't shoot Deligny but saw and knew the killer — his sister's boyfriend, the one who'd given police the gun, broken up into parts and stuffed into potatoes.
Jurors at Ruffin's trial heard from the boyfriend, but only about his relationships with the defendant, his sister and others in the case. When the jury was out of the room, the boyfriend invoked his Fifth Amendment right against self-incrimination and declined to answer other questions, including where he'd been on the night of the shooting.
Prosecutors didn't release the boyfriend's name Thursday, and the names of lawyers who have represented him weren't immediately available. He told prosecutors during their recent reinvestigation that he had nothing to do with the shooting and didn't give detectives the gun. He also said he never confessed to anyone, though prosecutors say Ruffin's stepfather, sister and late mother all have said he made admissions to them.
Asked Thursday about the boyfriend, Ruffin's lawyers noted that the prospect of any prosecution now is uncertain.
“We only wish that in 1996, Detective Scarcella and others had performed the investigation they should have and been able to get this right the first time," attorney Garrett Ordower said, noting that Deligny's family may now never have the finality of a conviction in his death.
As for Ruffin, he's focused on his future, including promotion opportunities at his job in Atlanta. His now-voided conviction, he said, “never defined me.”
“This never really spoke of the person I was or the man I was going to become,” he said. “So this, to me, is a great closure of a chapter my life, but my life is still going up.”

Beloved (1998) reviewed by Movies That Move We
MY THOUGHTS WHILE I VIEWED
3:44 ahh it came out a bad week. Ants/Rush Hour/Bride of Chucky/Practical Magic all were hits. Ants is animated. Rush Hour is funny and with jackie chan a global hit and rush hour was his finest usa based film. Chucky for the horror addicts, chucky is a superstar. PRactical magic had nicole kidman and sandra bullock in a women's empowerment film about new england witches... beloved
12:35 good point, I want to add, the multitude of stories is the problem. I argue the problem is, the truth is complex right. Some people were violent, some suffered, some had good fortune. it is a blend of stories. Blend of stories make the end of the civil war /13th amendment/end of slavery complicated
15:16 yes, this is a poltergeist. But i concur, the message is, what is more frightening is the human activity, the enslavement of whites onto blacks.
https://en.wikipedia.org/wiki/Margaret_Garner
I think it is an important story change from morrison that is carried in the film is that the real life garner was mulatto. she had a white parent. and all her children were from her owner.
I find it also interesting that most of the people they fled, with, the historical garner made it to canada. they didn't stay in the usa but most made it. supposedly seventeen in total with nine making it to canada. And i find it historically compelling that the Garner's owner/former owner/owner in moving the garner's around kentucky to escape an extradition order for murder from ohio which was going to lead to a pardon, he had to leave kentucky and on a boat to take the garner's to new orleans the baby child was thrown into the water by margaret and died. And then in the end, margaret lived, telling her husband never to marry and bring forth life into the world of slavery. I argue, margaret never let her black enslaved husband bed her or at least bed her in good time for pregnancy. I think margaret hated the idea of being pregnant. Only know have I did any research concerning the true story, thank you Nike, I have more thoughts for a story I am composing myself now.20:30 great point, i agree, from the beginning I saw this film as the poltergeist while present, while dangerous is not as dangerous as the white slave owners, not really. The poltergeist is easier to handle and is handled easier than white folks.
21:53 yes, we don't talk about the truth in the black community. because black parents can not guarantee black chidren will react positively to whites or the usa with knowing it. I have always felt most black parents in the usa, are frightened of the truth because all black parents know, 100% of black children will not reach positive conclusions to whites or the usa with the truth. And I think black parents in majority just don't want that risk so they lie.
22:44 how can the movie be better in your view Nike?
24:09 I can tell you I know black people were not dancing about based on knowing about my mother's father's mother's life. I do not go into my personal.
24:38 yes, trauma
25:02 i think the black community in the usa made an effort to kill the life of that past in the black community in the usa, even while white people keep it alive with their actions. and i think, those black people succeeded in killing it. The modern black community in the usa, to be blunt, does not reflect a community that used its most historically relevant or elemental era in the usa, that being when enslaved to whites, as a root element of a heritage to empowerment. The Black community in the usa , is a community that reflect a discarding of its most historically relevant or elemental era in the usa. Which has been beneficial. The USA today would not be the country it is if the Black community or the Indigenous community didn't at some point do what both did and that was, start at day one when at day 99. Black people talk about fighting in world war II and owning homes in the antebellum south. Enslavement was Black folk in the usa 300 year old epoch in the usa, that predated the usa itself. Our forebears who wanted that reboot, got what they wanted. at the price of it was the gullah language or culture like other unique cultures in the black community in the usa that predate the end of slavery, high john the conqueror and a horde of fiction fantasy that black people had created during slavery/the black free towns no one recalls today. Black people like henry louis gates jr and others like to emphasize the time after slavery cause , like frederick douglass, they want the black community in the usa to be statian, of the usa. The problem with black enslavement to whites being alive is the question of the usa itself. it has to live as well and when you question the country you live in, again the resulting answer may not be positive or convenient or majority. And I think many black people in the past have always feared and some today still fear that possibility in the black community in the usa. thus why said black people adore modern black immigrants who have more in common with whites when it comes to their initial relationship to the usa than DOSers.
QUESTIONS AND ANSWERS
What did you think of this film the first time you saw it?
I didn't like the whites, which says little to nothing. but, I enjoyed the end. Maybe cause I was raised in a home with two loving parents. I enjoyed the resolution at the end, between d and sethe.Did you know at the time, about Margaret Garner?
No, I did not. I never thought to research this until now. I think the true story is very compelling, about many issues of mulattoes, of black children in the usa,of the end of slavery or as I like to call one of the mutations of slavery. cause the truth is, slavery simply changed, it did not die. But I always remind people, new orleans was the las vegas of the usa in the 1800s and all the top female prostitutes of new orleans claimed black ancestry. why? white men had created a media myth, like modern day Black women behinds or white women breast. that mulatto women was the sexual best. And I even see the lustful logic. You have a white woman/a light black woman/a luscious black woman all in one white man's house. he is married to one, the white one. her role is to make heirs, she owns nothing. he uses one for general labor and mating for more produce<meaning aside black men>, the luscious black woman. but who is the best of both worlds. it is the light black woman, the mulatto. She is publicly owned by the white man. he has no worry of legal problems with anything he does to her, like the luscious black woman but she may in appearance look no different or more similar to a white woman. So, it is to a white man in a position of total power, the best of both worlds. Most mulattoes look like a thandie newton or halle berry where it is clear, they are a mix, but some look like Christina Cox <she was in chronicles of riddick> or rebecca hall <the director of passing>who in my view can attempt to pass in the old environment in the usa way better than ruth negga or tessa thompson. And I use myself as the proof. I never doubted ruth negga or tessa thompson or halle berry have black ancestry but christina cox or rebecca hall i did not know. and this is powerful. Remember twelve years a slave. paul giamatti's character pointed to the mulatto daughter of the luscious black woman, whose tears and constant crying in light of margaret garner is well balanced, and said, i paraphrase, that little girl is worth all of the rest.. to cumberbatch. In latin america, they are called Alvino's meaning. this is someone with known black ancestry but who does not look black. That is priceless to a white man with money back in slave times.
Thanks again Nike, In cheap retrospect, I Would had went another way than Morrison story wise, plot wise. But morrison being a woman, i think she wanted to redeem the black mother more than anything. I think beloved, as a poltergeist, was betrayed a little bit. I daresay, beloved is more a wraith than a poltergeist. A poltergiest for me acts wildly as a spirit but doesn't necessarily have agenda. a wraith has agenda. the woman in black is a wraith. I think beloved is a wraith. She wants her mother to give take her own life through a slow pain of neglect. that is purpose. Beloved goes away as a poltergiest not a wraith.Did you feel differently about the meaning of the film between your first watch and the last time you viewed the movie?
Meaning, no , the meaning didn't change. I only add the comparison to the real event know. I remember relatives not liking that she didn't kill herself. The funny thing in the historical record it seems she was literally stopped by the whites coming to take her back to slavery. but I like how in the historical record she tried to kill herself with the youngest, but simply failed.Do you think of this as a horror movie?
Yes, but I want to say, this film is a visual representation of what I will call Black Statian Slave Ghost Stories. Growing up as a kid, I was told and then later read many of these kinds of stories, usually shorter in length but the same idea. Being enslaved while dealing with a negative spirit is uncommon theme or shall i say a specific theme to the Black DOS community in the USA. this isn't for willing immigrants or whites or native americans mostly, this is a very specific genre culturally. You have a character dealing with a scenario where they are born disempowered with problems stemming from a past before they were born they can not control while now a negative spirit. I think in these stories the problem is, the horror of the ghost is less important than the horror between humans and that goes against the horror movie genre as a whole in the usa. yes, the ghost is bothering me, but I had my foot cut off and my testicles branded last month. I can't afford any more from this white man so spirit, pick a number.yeah, good one:)

MY COMMENT
Dune was a serial in a magazine, turned into a book. but star wars was based on John Carter of Mars over Dune. The multiversity of characters in star wars reflects John carter more than Dune.

My THoughts
like the montage of reviews
2:10 so many black female writers enjoy PEele's style. I do to but many black female writers tend to start off saying that.
5:40 exactly, I wonder if a 1960s hippie's old plan written on home made paper somewhere wasn't what hands across america stemmed from
7:50 spider grandmother https://en.wikipedia.org/wiki/Spider_Grandmother
11:36 yes, anansi, the story teller, remember anansi has a caribbean version , same name, different stories
13:09 random thought, was the homeless guy taken to a hospital carrying the sign some sort of guard for the doppels/tethers?
Questions how we respond to those who have less than us? What would you do if you came face to face with your darker side?
Your questions are strong. Collective reply as opposed to individual reply. In the film US, the tether abigail answers the question to individual reply by exchanging places. but the originally untethered abigail, replied to her individual revenge with a collective reply, leading all the tethers. and oddly enough, in the end, both abigails got what they wanted, in the end, the collective reply of the originally untethered abigal with hands across america happened with her side her household all killed while the tethered got her replacement life with only her male son, the "mulatto" knowing the truth about her. and her whole household lives. The power of nature here is underrated. I even argue an element of "The man who fell to earth" is used very well in this film's premise. In a man who fell to earth, the government keeps the "alien" man in a base but over time the base is forgotten. How isn't fully explained but whatever happened, the people in government who knew about this or kept it organized died or forgot or moved on, so the installation ran on autopilot, and became decrepit. like the tether's world, its sitting there. Whomever in government was supposed to manage them, stopped or moved on or died or something, where they still get electricity, but their existence is uncared for. And I like that theme of whatever the government was planning couldn't survive nature. But to your first question, to whether people have more or less, whether we want freedom or revenge, we can respond as part of a group or individually. But nature does have influence over things, At the end the tricked abigail was still naive when she was originally tricked and the tethered abigal is still dangerous when she originally forced a switch. Their varying sense of individualism or community didn't change. The tricked abigal, felt the tethered abigail in the first place, she was always communal. the tethered abigail was always an individual, never once interested in helping another tethered escape. So no matter how you respond to another, you will always be yourself eventually.
Well, I will answer, what will I do if I come into contact with one of my infinite other sides? There is a version of me that is more positive than me. and thus, I am the more negative to that version. to answer the question. I don't know. Good question. the engineer in me wants to ask, how did we even meet in the first place. Nature has rules. how are we meeting is my first question, not necessarily how we will get along. But I will say this. The key to coexisting side another interpretation of you, is to be anti christian. I will explain. If you look at zoarasters-ancient kemet-aztec mythology-taoism, most spiritual belief systems accept that nature is not good or bad but all things. But the christian belief system is starkly variant. the christian tradition says god is good, thus that which is not good is not of the essence of life. If you see a version of you doing negative things that you wouldn't do, if you have in your mind the idea that to do negative things is against nature, then you will imply that the other you is unnatural and thus communication problems, coexistence problems.Thistle and Verse
