There's breaking news from the astronomy world. Astronomers have confirmed that we really don't understand something we only suspected we didn't understand, in yet another study after years of their observations clashing with theorists' predictions. And we can hope their new measurements helps us ultimately understand it because, at least, now we know what we were wrong about. What am I talking about? Well, it's something called the "Hubble tension," and it's a dispute between observational astronomers and theoretical cosmologists about who's been wrong about how fast the universe is expanding. Now new observations from the James Webb Space telescope, published this week in The Astrophysical Journal , back up previous measurements that peg the speed of the expansion as faster than what the theoreticians believe it should be. That's made the score 2-1 for the astronomers and the theoreticians have some explaining to do. Let's take this one step by step. In 1929, American astronomer Edwin Hubble announced his discovery that galaxies scattered throughout the universe are moving away from each other — and that the farther away they are, the faster they are moving. This suggests that the universe is expanding as the space between the distant galaxies stretches outwards. Hubble's landmark discovery has challenged scientists ever since, as they try to determine just how fast that expansion is with a value known as the Hubble constant. An artist's concept showing the expansion of the universe over time since the Big Bang. (NASA Goddard Space Flight Center) Fast forward to 1998 when two independent teams of astronomers used images from the Hubble Space Telescope to peer deeper and farther back into the universe than had ever been possible before. They discovered, shockingly, that something very weird was happening. They found that the rate at which the universe was expanding was increasing over time. This was like throwing a baseball up in the air and finding it not falling back to Earth, but accelerating into outer space. Thus was born the notion of dark energy, the mysterious force that somehow causes the universe's expansion to accelerate, possibly by causing space itself to expand. These paradoxical discoveries threw a wrench into the standard model of cosmology, a mathematical model of the history and evolution of the universe that told the story of its expansion from the moments after the Big Bang. Theorists happily integrated the dark energy into their math, as well as another mysterious factor: dark matter, an invisible and undetectable cosmological phenomenon whose immense gravitational influence pervades the universe. It was a beautiful new theory. But the math and observations from the universe wouldn't cooperate. The standard model predicts that the modern universe should be expanding at a rate of 67.4 kilometres per second per megaparsec (km/s/Mpc) , where a megaparsec covers a huge distance of 3.26 million light-years. But models are only as good as the blackboards they are written on. The Hubble telescope precisely measured the rate at which the universe is expanding by looking at relatively nearby galaxies, and in 2018 found a higher rate of 72.8 km/s/Mpc. This, I can only imagine, led to awkward encounters in physics department common rooms in universities around the world, as the theoreticians and the astronomers desperately pretended that those few megaparsecs weren't that big a deal. As I said — "Hubble tension." In 2023, observations from the James Webb Space Telescope seemed to back up the Hubble Space Telescope findings. Then in February 2024, the same team updated their research with even more data backing up their initial findings. The tension, in other words, continued. The latest study using the largest sample of Webb observations yet, and three different methods to cross-check the Hubble telescope data, arrive at a very similar value of 72.6 km/s/Mpc. The two space telescopes' findings bolster the case there is something, other than measurement error, influencing the universe's expansion rate — and that our theoretical understanding of the universe is incomplete. The Cepheid variable star, used as a reference for measuring the universe’s rate of expansion, is much crisper in the Webb version, left, compared to the Hubble image, right. (Adam G. Riess/Johns Hopkins University/Space Telescope Science Institute/Canadian Space Agency/European Space Agency/NASA) This, for both the theorists and the astronomers, is good news. The astronomers get to be right, which is nice. The theorists get to look for one of the holy grails of science: new physics, which roughly translates as "clean the blackboards — it's game on!" They know their old math was wrong, which means there's something new out there to discover. This is often how basic science works. The theoreticians and experimentalists are volleying back and forth to find the ultimate truth. This may sound far removed from everyday life — and while it won't influence how much tax you pay this year, it is attempting to answer the basic question of how we got here. And when we probe the fundamental forces that shape the universe as a whole, sometimes new discoveries are made that could have amazing implications in the future.CHAMPAIGN — Kylan Boswell had 18 points, 10 rebounds and 10 assists and Tomislav Ivišić scored 23 points to lead No. 24 Illinois to a 117-64 victory over winless Chicago State on Sunday. Boswell got his first triple-double with a pass that set up Keaton Kutcher’s 3-pointer with 1:47 left. It was the seventh triple-double in program history. Dre Gibbs-Lawhorn scored 16 points, Kasparas Jakucionis had 14, Will Riley had 13 and Morez Johnson Jr. had 11 points and eight rebounds for the Illini (9-3). Gabe Spinelli, son of first-year head coach Scott Spinelli, led the Cougars (0-15) with 20 points and Noble Crawford scored 15. The Illini led 60-24 at halftime and built their lead to as many as 58 points in the second half. This wasn’t much of a test for the Illini, who were facing a winless team that doesn’t have a player averaging in double figures and gives up 83 points per game. But it gave them a chance to shake off the rust from having a week off following their Braggin’ Rights win over Missouri on Dec. 21. It was another bad day for the Cougars, who were outrebounded 47-23, committed 15 turnovers and shot 37%. On a positive note, they were 4 for 4 at the free-throw line. A 14-point run over a 2 1/2-minute stretch early in the first half extended an 8-7 lead to 22-7 and propelled the Illini to the lopsided win. The Illini shoot a lot of 3s. They came into the day averaging 32 per game, No. 6 in the nation, and went 15 for 33. The Illini plays Thursday at No. 9 Oregon. The Cougars play Friday at Wagner.super jili ph 。

Thousands of Syrians gathered on Friday in Damascus 's historic main mosque and in the capital’s largest square to celebrate the ousting of Bashar al-Assad. The jubilant scenes were a major symbolic moment since the downfall of the Syrian dictator, coinciding with the first Muslim Friday prayers since he fled the country for Russia. Huge crowds, including some insurgents, packed Damascus' historic Umayyad Mosque in the capital's old city, many waving the rebel opposition flag which has replaced the Assad-era flag. According to Arab TV stations, the Friday sermon was delivered by Mohammed al-Bashir , the interim prime minister installed by HTS, the rebel group which seized control of Damascus and other major cities. The square, a major symbol of Syria , had often been a site of brutal repression under Assad after rallies broke out in 2011. The crowd chanted calls for a free Syria, while others shouted slurs against Assad and his late father, whose tomb was set alight by rebels earlier this week. One man in the crowd, 51-year-old Khaled Abu Chahine, originally from the southern province of Daraa, where the 2011 uprising first erupted, said he hoped for "freedom and coexistence between all Syrians, Alawites, Sunnis, Shiites and Druze." "The former government was a government of crime and executions," he told the AP news agency, calling on foreign nations "hosting these gangs to bring them to justice and those who are in Syria and committed crimes should face justice." The main insurgent force, Hayat Tahrir al-Sham, has been working to establish security and start a political transition after seizing Damascus early Sunday. The group has tried to reassure a public both stunned by Assad's fall and concerned over extremist jihadis among the rebels. The insurgents' leadership says it has broken with its extremist past, having started as an off-shoot of Al Qaeda. HTS is still labeled a terrorist group by the UK, the United States and major European countries. HTS's leader, Ahmad al-Sharaa, formerly known as Abu Mohammed al-Golani, appeared in a video message Friday congratulating "the great Syrian people for the victory of the blessed revolution." "I invite them to head to the squares to show their happiness without shooting bullets and scaring people," he said. "And then after we will work to build this country and as I said in the beginning, we will be victorious by the help of God." It comes as Syrians began exploring the abandoned homes of the former dictator, including the family’s massive summer resort in Burj Islam, overlooking the Mediterranean. The property lay in disrepair on Friday after heavy looting and damage, with shattered windows and broken fixtures. Following Assad's toppling, locals, mostly Syrian Turkmen driven out to nearby villages during the construction of the resort, entered the area for the first time since the Assad family built it 50 years ago. Assad is said to have removed his valuables from the villa by sea using small boats.OpenAI’s legal battle with Elon Musk reveals internal turmoil over avoiding AI ‘dictatorship’

NEW YORK — The man charged with killing UnitedHealthcare CEO Brian Thompson was not a client of the medical insurer and may have targeted it because of its size and influence, a senior police official said Thursday. NYPD Chief of Detectives Joseph Kenny told NBC New York in an interview Thursday that investigators have uncovered evidence that Luigi Mangione had prior knowledge UnitedHealthcare was holding its annual investor conference in New York City. Mangione also mentioned the company in a note found in his possession when he was detained by police in Pennsylvania. Suspect Luigi Mangione is taken into the Blair County Courthouse on Tuesday in Hollidaysburg, Pa. "We have no indication that he was ever a client of United Healthcare, but he does make mention that it is the fifth largest corporation in America, which would make it the largest healthcare organization in America. So that's possibly why he targeted that company," Kenny said. UnitedHealthcare is in the top 20 largest U.S. companies by market capitalization but is not the fifth largest. It is the largest U.S. health insurer. Mangione remains jailed without bail in Pennsylvania, where he was arrested Monday after being spotted at a McDonald's in the city of Altoona, about 230 miles west of New York City. His lawyer there, Thomas Dickey, said Mangione intends to plead not guilty. Dickey also said he had yet to see evidence decisively linking his client to the crime. Mangione's arrest came five days after the caught-on-camera killing of Thompson outside a Manhattan hotel. Luigi Mangione, a 26-year-old Ivy League graduate, was arrested on December 9, 2024, after a six-day manhunt and charged with the murder of UnitedHealthcare CEO Brian Thompson. His arrest has sparked a viral social media movement, with many hailing him as a symbol of resistance against systemic healthcare failures. The #FreeLuigi movement gained significant traction, with his social media profiles amassing over 100,000 new followers before being suspended. Despite this, the movement continues to trend, highlighting public discontent with the U.S. healthcare system. Some social media users argue that Mangione's radicalization stemmed from the struggles faced by millions in obtaining necessary healthcare, and not from his university education. Mangione’s arrest at a McDonald's in Altoona led to the seizure of a "ghost gun," a suppressor, fake IDs, and a manifesto criticizing the healthcare system. While the manifesto seems to admit guilt, some users question Mangione's responsibility, pointing out discrepancies in surveillance photos. The fascination with Mangione has only intensified, with discussions about his attractiveness and comparisons to characters in Ryan Murphy's productions. The phenomenon is reminiscent of society's long-standing obsession with infamous criminals, blurring lines between horror and hero worship. Former FBI agent Rob D’Amico noted that Mangione is seen by some as a "Robin Hood" figure fighting against corporate greed, which complicates the investigation. Police say the shooter waited outside the hotel, where the health insurer was holding its investor conference, early Dec. 4. He approached Thompson from behind and shot him before fleeing on a bicycle through Central Park. Mangione is fighting attempts to extradite him back to New York so that he can face a murder charge in Thompson's killing. A hearing was scheduled for Dec. 30. The 26-year-old, who police say was found with a " ghost gun " matching shell casings found at the site of the shooting, is charged in Pennsylvania with possession of an unlicensed firearm, forgery and providing false identification to police. Luigi Mangione was arrested Monday in Altoona, Pennsylvania, in connection with the killing of UnitedHealthcare CEO Brian Thompson in what law enforcement has called a "targeted attack." Mangione is from a prominent Maryland family with extensive business interests. The Mangione family is known for developing real estate and running businesses. Relatives expressed shock over the arrest and offered condolences to Thompson’s family. Mangione faces multiple charges, including murder, firearm possession, and forgery, in New York and Pennsylvania. Mangione is an Ivy League graduate from a prominent Maryland real estate family. In posts on social media, Mangione wrote about experiencing severe chronic back pain before undergoing a spinal fusion surgery in 2023. Afterward, he posted that the operation was a success and that his pain improved and mobility returned. He urged others to consider the same type of surgery. On Wednesday, police said investigators are looking at his writings about his health problems and his criticism of corporate America and the U.S. health care system. Kenny said in the NBC interview that Mangione's family reported him missing to San Francisco authorities in November.

A 7-year-old dispute between tech leaders Elon Musk and Sam Altman over who should run OpenAI and prevent an artificial intelligence "dictatorship" is now heading to a federal judge as Musk seeks to halt the ChatGPT maker's ongoing shift into a for-profit company. Musk, an early OpenAI investor and board member, sued the artificial intelligence company earlier this year alleging it had betrayed its founding aims as a nonprofit research lab benefiting the public good rather than pursuing profits. Musk has since escalated the dispute, adding new claims and asking for a court order that would stop OpenAI’s plans to convert itself into a for-profit business more fully. The world's richest man, whose companies include Tesla, SpaceX and social media platform X, last year started his own rival AI company, xAI. Musk says it faces unfair competition from OpenAI and its close business partner Microsoft, which has supplied the huge computing resources needed to build AI systems such as ChatGPT. “OpenAI and Microsoft together exploiting Musk’s donations so they can build a for-profit monopoly, one now specifically targeting xAI, is just too much,” says Musk's filing that alleges the companies are violating the terms of Musk’s foundational contributions to the charity. OpenAI is filing a response Friday opposing Musk’s requested order, saying it would cripple OpenAI’s business and mission to the advantage of Musk and his own AI company. A hearing is set for January before U.S. District Judge Yvonne Gonzalez Rogers in Oakland. At the heart of the dispute is a 2017 internal power struggle at the fledgling startup that led to Altman becoming OpenAI's CEO. Musk also wanted the job, according to emails revealed as part of the court case, but grew frustrated after two other OpenAI co-founders said he would hold too much power as a major shareholder and chief executive if the startup succeeded in its goal to achieve better-than-human AI known as artificial general intelligence, or AGI. Musk has long voiced concerns about how advanced forms of AI could threaten humanity. “The current structure provides you with a path where you end up with unilateral absolute control over the AGI," said a 2017 email to Musk from co-founders Ilya Sutskever and Greg Brockman. “You stated that you don't want to control the final AGI, but during this negotiation, you've shown to us that absolute control is extremely important to you.” In the same email, titled “Honest Thoughts,” Sutskever and Brockman also voiced concerns about Altman's desire to be CEO and whether he was motivated by “political goals.” Altman eventually succeeded in becoming CEO, and has remained so except for a period last year when he was fired and then reinstated days later after the board that ousted him was replaced. OpenAI published the messages Friday in a blog post meant to show its side of the story, particularly Musk's early support for the idea of making OpenAI a for-profit business so it could raise money for the hardware and computer power that AI needs. It was Musk, through his wealth manager Jared Birchall, who first registered “Open Artificial Technologies Technologies, Inc.”, a public benefit corporation, in September 2017. Then came the “Honest Thoughts” email that Musk described as the “final straw.” “Either go do something on your own or continue with OpenAI as a nonprofit,” Musk wrote back. Musk didn't immediately respond to emailed requests for comment sent to his companies Friday. Asked about his frayed relationship with Musk at a New York Times conference last week, Altman said he felt “tremendously sad” but also characterized Musk’s legal fight as one about business competition. “He’s a competitor and we’re doing well,” Altman said. He also said at the conference that he is “not that worried” about the Tesla CEO’s influence with President-elect Donald Trump. OpenAI said Friday that Altman plans to make a $1 million personal donation to Trump’s inauguration fund, joining a number of tech companies and executives who are working to improve their relationships with the incoming administration.U.S. president-elect Donald Trump wants to turn the lights out on daylight saving time. In a post on his social media site Friday, Trump said his party would try to end the practice when he returns to office. “The Republican Party will use its best efforts to eliminate Daylight Saving Time, which has a small but strong constituency, but shouldn’t! Daylight Saving Time is inconvenient, and very costly to our Nation,” he wrote. Setting clocks forward one hour in the spring and back an hour in the fall is intended to maximize daylight during summer months, but has long been subject to scrutiny. Daylight saving time was first adopted as a wartime measure in 1942. Lawmakers have occasionally proposed getting rid of the time change altogether. The most prominent recent attempt, a now-stalled bipartisan bill named the Sunshine Protection Act, had proposed making daylight saving time permanent. The measure was sponsored by Florida Sen. Marco Rubio, whom Trump has tapped to helm the State Department. “Changing the clock twice a year is outdated and unnecessary,” Republican Sen. Rick Scott of Florida said as the Senate voted in favor of the measure. Health experts have said that lawmakers have it backward and that standard time should be made permanent. Some health groups, including the American Medical Association and American Academy of Sleep Medicine, have said that it’s time to do away with time switches and that sticking with standard time aligns better with the sun — and human biology. Most countries do not observe daylight saving time. For those that do, the date that clocks are changed varies, creating a complicated tapestry of changing time differences. Arizona and Hawaii don't change their clocks at all.
