A low intergalactic grumbling is emanating from deep space, according to scientists. And no, it’s not the start of the end times. Astronomers say they detected the first-of-their-kind low frequency ripples, described as a “cosmic bass note” of gravitational waves, which is thought to be caused by supermassive black holes merging across the universe. The discovery could unveil new secrets about how the monster black holes, which lie at the centre of galaxies, work. The objects are millions – possibly billions – the times the mass of the sun, but little is known about them because no light can escape. Sign up to our free Indy100 weekly newsletter “This is huge news,” said Dr Stephen Taylor, chair of the North American Nanohertz Observatory for Gravitational Waves (Nanograv) consortium, which led the team which made the discovery, and an astrophysicist at Nashville’s Vanderbilt University. Dr Michael Keith, of Jodrell Bank Centre for Astrophysics and a member of the team which helped find the signal, added: “The results presented today mark the beginning of a new journey into the universe to unveil some of its unsolved mysteries. “We are incredibly excited that after decades of work by hundreds of astronomers and physicists around the world, we are finally seeing the signature of gravitational waves from the distant universe.” Before the discovery, scientists have only captured short “chirps” of gravitational waves which are linked to the massive objects merging. But the “bass note” comes after they tuned into a deeper range of frequencies. It is thought to be caused by a single complete gravitational wave travelling at the speed of light. Astronomers think it is produced by the entire population of supermassive black hole binaries from over roughly the last 8bn years of the universe. “We think each pair contributes a little wave, which is added to a little wave of another, and all together that is what we may see right now – a sort of murmur of the entire population,” said Prof Alberto Vecchio of the University of Birmingham and a member of the European Pulsar Timing Array. Prof Andrew Pontzen, a cosmologist at University College London, added: “It’s not often that we get a glimpse of the universe through a totally new lens, but after 15 years of patient work, Nanograv seems to be providing just that. It’s tremendously exciting to see initial evidence for these waves, which will eventually teach us an enormous amount about supermassive black holes, hundreds of millions of times the mass of the sun.” The findings were published on 29 June by Astrophysical Journal Letters.

Fans of Diet Coke have reacted with despair at reports that the World Health Organisation (WHO) may catagorise aspartame – an artificial sweetener in the drink – a potential carcinogen. It was reported on Thursday (29 June) that the health organisation’s cancer research unit, the International Agency for Research on Cancer (IARC), is preparing to label aspartame as potentially cancerous from July. Aspartame is a low-calorie artificial sweetener that is approximately 200 times sweeter than sugar and is used in a huge number of soft drinks, including Diet Coke, Pepsi Max, Diet Irn Bru, and Sprite Zero, among others. It is also used in foods such as chewing gum, candy, breakfast cereal, frozen desserts and puddings, and gelatins. Although the IARC’s ruling on the sweetener remains confidential until July, Diet Coke fans are already wondering if they might have to give up their favourite fizzy drink. “If they interfere with Diet Coke it will be the final straw for me I’m afraid,” one person warned. Another joked they have already “drunk the Diet Coke equivalent of swimming at a superfund site” in their lifetime. “You can take away my Diet Coke when you pry it out of my cold dead hands,” a third mordantly added. “Listen, if you’re going to take away Diet Coke from us, you better be prepared for 72 per cent of women aged 25-45 to quit their jobs,” another person claimed. “That’s all I’m saying. *Cracks open third Diet Coke before noon*” Others appeared smug that they had never switched from regular full-fat Coke – which contains around 10.6g of sugar per 100ml, equating to 35g per 330ml can – to the low-sugar version. One person referred to a scene from hit series Friends that showed Chandler (Matthew Perry) shouting: “I knew it!” Another said: “I told you all that Diet Coke was just as bad as regular Coke.” The IARC is expected to make its decision over aspartame public on 14 July, the same day as the Joint WHO and Food and Agriculture Organisation’s Expert Committee on Food Additives (JECFA), which is also reviewing aspartame use this year. JECFA has said it is safe to consume aspartame within accepted daily limits since 1981. An adult weighing 60kg (132 pounds) would have to drink between 12 and 36 cans of diet soda every day to be at risk, a view widely shared by national regulators. The additives committee “conducts risk assessment, which determines the probability of a specific type of harm (eg., cancer) to occur under certain conditions and levels of exposure”. The review of aspartame comes after a study conducted by experts from the French National Institute for Health and Medical Research, and Sorbonne Paris Nord University, published on March 2022, claimed it could increase the risk of cancer in people who consume it. But previous large-scale studies on humans have not revealed similar associations. A separate study published last December found that aspartame was linked to anxiety in mice. The deputy chief scientific adviser of the UK’s Food Standards Agency, Rick Mumford, commented on reports and said: “Our view is that the safety of this sweetener has been evaluated by various Scientific Committees and it is considered safe at current permitted use levels. “The IARC report has not yet been published and, when it is, it will be examined by the JECFA, who will put together a risk assessment by the end of July. We will closely study JECFA’s report and decide whether any further actions are needed.” The Independent has contacted Coca-Cola for comment.

Federal prosecutors arrested three investors on Thursday on insider trading charges related to a deal to take former President Donald Trump's media business public.

Fans of The X Files have got a new alien-related US government drama to get stuck into, it seems. Senior Republican Marco Rubio claims that those who have reported alien aircraft being retrieved by the US government “have held very high clearances and high positions within our government." The Florida senator and vice chair of the Select Committee on Intelligence did not reveal who had come forward with claims, but said: “Frankly, a lot of them are very fearful.” Sign up to our free Indy100 weekly newsletter “Fearful of their jobs, fearful of their clearances, fearful of their career.” At the start of June, James Comer, chair of the influential House Oversight Committee, said the group was looking into allegations that a top-secret military program already had a fully intact UFO. Republicans Anna Paulina Luna of Florida, a committee member, and Tim Burchett of Tennessee, who is not a committee member but has made claims about a government cover-up on the subject in the past, are to lead the probe. The investigation came after David Grusch, a 36-year-old airforce veteran, made public claims about UFOs. Grusch previously worked at the National Reconnaissance Office, on what is now referred to as Unidentified Aerial Phenomena (UAPs). Grusch told NewsNation that the government had retrieved a number of “non-human origin technical vehicles,” some of which contained “dead pilots”. “There are people who have come forward to share information with our committee over the last couple of years,” Rubio said on 26 June. Referring to Grusch, he added: “I would imagine some of them are potentially some of the same people perhaps he’s referring to.” Following the NewsNation interview, Department of Defense spokesperson Sue Gough said it had “not discovered any verifiable information to substantiate claims that any programs regarding the possession or reverse-engineering of any extraterrestrial materials have existed in the past or exist currently.” NASA also said that despite one of its priorities being the search for extraterrestrial life, it had not found credible evidence. Rachel Partlow, communications director for Burchett, told Newsweek on 27 June that the congressman was “aware” of Grusch's claims. She declined to comment on whether the veteran would be brought in to provide testimony, with hearing dates not yet set in stone. Have your say in our news democracy.
