Scientists have “heard” a chorus of gravitational waves rippling through the universe, in what they say is an unprecedented finding that could fundamentally change our understanding of the universe. The discovery, described in a range of newly published journal papers, suggests that spacetime is being rocked by intensely powerful gravitational waves all the time. Those waves carry a million times more energy than the one-off bursts of gravitational waves that were detected from a black hole and were themselves hailed as a major breakthrough in our understanding of the universe. The new results suggest that everything is being slowly shrunk and expanded by a new kind of gravitational wave as they pass through our galaxy. Scientists describe it as being akin to hearing a “symphony” of waves echoing through the universe. “It’s like a choir, with all these supermassive black hole pairs chiming in at different frequencies,” said Chiara Mingarelli, a scientist who worked on the new findings while an associate research scientist at the Flatiron Institute’s Center for Computational Astrophysics. “This is the first-ever evidence for the gravitational wave background. We’ve opened a new window of observation on the universe.” The new findings have been described in a range of journal articles, published in different academic journals. The research is the result of 25 years of observations from six of the world’s most sensitive radio telescopes, and have been simultaneously published by different collaborations across the world. The findings are not only notable in themselves. They also offer the opportunity to find out some of the universe’s secrets, since they can be used to find information about the binary black holes that form when galaxies merge, for instance. “These results signify the beginning of an exciting journey into the Universe, where we aim to unravel its mysteries,” Michael Keith, a lecturer at Jodrell Bank Centre for Astrophysics, UK, and contributor to one of the new studies, published in Astronomy and Astrophysics. “After decades of tireless work by hundreds of astronomers and physicists worldwide, we are finally detecting the long-awaited signature of gravitational waves originating from the distant Universe.” Scientists made the discovery by analysing observations of pulsars, which are extinguished stars that can be used as reliable clocks in the distant universe. By bringing together such a large amount of detailed data, researchers were able to measure those pulsars with very high accuracy, allowing them to measure gravitational waves at a far larger scale than using detectors on Earth. “Pulsars are excellent natural clocks. We exploit the remarkable regularity of their signals to detect subtle changes in their rhythm, enabling us to perceive the minute stretching and squeezing of space-time caused by gravitational waves originating from the far reaches of the Universe,” said David Champion, a senior scientist at the MPIfR in Bonn, Germany, and contributor to the study, in a statement. For now, researchers are only able to “hear” the vast choir, rather than the individual pulsars that make up its singers. But together they are much louder than expected, meaning that there may be more or more heavy supermassive black holes to be found in the universe.

Travis Barker has revealed the unique names he’s considering for the son he and Kourtney Kardashian have on the way. During the latest release of Complex’s “GOAT Talk” video, the 47-year-old drummer and his 17-year-old daughter Alabama sat down to answer rapid fire questions about favourite gifts, rap albums, restaurants, and more. The last card Barker picked up asked the two of them what they thought “the greatest baby name of all time” was. “I like Rocky Thirteen,” the Blink-182 bandmate admitted. “That’s the name that’s been going through my head.” Alabama barely gave her father a chance to explain himself before telling him: “That’s so bad.” The social media star couldn‘t help but laugh at Barker’s confession, adding “he knows it’s bad.” But Barker wasn’t joking as he then revealed his sentimental reasons for loving the unique moniker. “Rocky George played guitar for Suicidal Tendencies. And 13 is just the greatest number of all time,” the instrumentalist proclaimed. Additionally, Barker – who named Alabama after his favourite movie True Romance – pointed out that “Rocky Thirteen” could also serve as a tribute to “the greatest boxing movie of all time,” 1976’s Rocky. Although Barker seemed set on the rock-inspired name, he knew not everyone was going to love the idea. In an attempt to sway him from his choice, Alabama continued to express her doubt over the potential name for her soon-to-be baby sibling. “You sure you’re going to name your kid Rocky Thirteen?” the internet personality asked. “Possibly,” Barker replied. The father of three could end up scraping the idea for another name he’s mentioned to his wife. Following the pair’s public pregnancy announcement in June, the eldest Kardashian sister, mother to Mason, 13, Penelope, 11, and Reign, 8, shared photographs from her maternity shoot on Instagram. Under the batch of images, Barker commented: “I already know his name.” While he didn’t offer the moniker he had in mind, he previously wrote under an older photo on the Kardashian’s account from November 2021: “Our son’s name would be Elvis.” Barker proposed to Kardashian in October of 2021 on the beach at their favourite Santa Barbara spot. From a late night at a little white chapel in Las Vegas, an intimate ceremony at a courthouse to sign their marriage licenses, to a traditional Dolce and Gabbana-themed wedding in Portofino, Italy, the pair tied the knot several times. On 17 June, Kourtney revealed she was pregnant after multiple rounds of IVF when she waved a huge sign that read, “Travis, I’m pregnant,” at the artist’s Blink-182 show in Los Angeles. Her reveal was a nod to a scene in the band’s “All The Small Things” music video, where a woman does the same thing. Barker wiped his eyes before hopping down from the stage to embrace a beaming Kardashian.
