Massive bubble of galaxies could be ‘fossil of the Big Bang’, say scientists
A huge bubble of galaxies that is one billion lightyears across could be a remnant of the ripples caused by the Big Bang, according to astronomers who have mapped the structure. The structure, named Hoʻoleilana by University of Hawaii scientists, is thought to have been caused by so-called Baryon Acoustic Oscillations (BAOs). These were ripples in the particles of the early Universe in the period following the Big Bang, when planets, solar systems and galaxies were not yet fully formed. As the ripples went outward, they created areas of density in the particles, causing bubble-like structures in which galaxies eventually coalesced. Until now, the BAOs were just a prediction – part of the wider Big Bang theory. No specific structures in the Universe had been found which mimicked their patterns. But Hoʻoleilana fits the description of these huge cosmic bubbles perfectly, according to Brent Tully, who led the study at the University of Hawaii’s Institute for Astronomy. “We were not looking for it. It is so huge that it spills to the edges of the sector of the sky that we were analyzing,” he said. “As an enhancement in the density of galaxies it is a much stronger feature than expected. The very large diameter of 1bn light years is beyond theoretical expectations. “If its formation and evolution are in accordance with theory, this BAO is closer than anticipated, implying a high value for the expansion rate of the universe.” The bubble is absolutely huge. It is made up of several superclusters, structures which themselves are thought to be among the Universe’s largest arrangements of matter. This includes the Hercules Supercluster, the Corona Borealis Supercluster and the Sloan Great Wall. All of these structures contain thousands of galaxies. In the middle of Hoʻoleilana sits the Bootes Supercluster and the Bootes Void, an immense space of nothingness which is an incredible 330m lightyears across. Daniel Pomarede, from the CEA Paris-Saclay University, who contributed to the research, said: “It was an amazing process to construct this map and see how the giant shell structure of Ho’oleilana is composed of elements that were identified in the past as being themselves some of the largest structures of the universe.” The research was published on 5 September in The Astrophysical Journal.

Did Taylor Swift really put Travis Kelce 'on the map'?
You can always rely on Swifties to keep fans in the loop about Taylor Swift's rumoured romances. Now, attention has been turned to Travis Kelce after the singer appeared at the Arrowhead Stadium on Saturday to watch the NFL player's latest game. Travis, 33, and his brother Jason, 35, have a podcast together called New Heights. And in a teaser for the latest episode, the elder sibling said it was time to address the hearsay. "We've been avoiding this subject out of respect for your personal life - now we've got to talk about it," Jason said. Travis replied: "My personal life that is not so personal. I did this to myself Jason, I know this." His big bro then asked: "So Trav, how does it feel that Taylor Swift has finally put you on the map?" Fans soon flooded the snippet with comments, with one writing: "Am I really about to watch a… sports podcast." Another joked: "Me leaving my book every 5 seconds to check TikTok updates for the Taylor Swift and Travis Kelce romcom." Meanwhile, a third TikToker wrote: "I love that Jason even says Taylor put Travis on the map." @newheightshow New Episode. TOMORROW. ? For the blissfully unaware, Travis Kelce is a tight end for the Kansas City Chiefs who, American football fans would argue, has long been a superstar in his own right. Kelce is an eight-time Pro Bowler and hold the NFL record for most overall seasons with 1,000 yards receiving by a tight end with 7. The 33-year-old also owns the record for most receiving yards by a tight end in a single season – despite just playing 15 games. Despite being a successful sportsman, he and Swift have become the latest topic of conversation after a four-second clip of the pair leaving Kansas City's Arrowhead stadium went viral. US jounalist Jarrett Payton, who shared the footage to X/Twitter, said it has been "the craziest 24 hours of my life". "I was at the right place at the right time last night," Payton told the BBC.
