I recently went to a new salon for a haircut and felt a little anxious. I didn’t know my stylist, but the bigger problem was that I didn’t know exactly what I was asking for. I didn’t have time to source inspiration images, and I felt the vibe I communicated was pretty vague: I was after more than just a trim, but wanted to keep my hair long for the remainder of the summer.

They may not be as stylish as a DeLorean or as sturdy as a blue police box, but wormholes in space could hold the key to real-life time travel – and a team of experts think they’ve figured out how. The trio of scientists delved deep into the laws of physics and discovered that it might be possible for humans to one day zip across galaxies in a matter of seconds, or journey through time itself. Now, this is all to do with the general theory of relativity and quantum physics, so don’t expect to get your head around it too easily. However, in their paper, Valeri P. Frolov and Andrei Zelnikov of Canada’s University of Alberta, and Pavel Krtouš of Prague’s Charles University proposed that a specific kind of wormhole would “inevitably” be “transformed into a time machine” if it was subject to particular conditions. Sign up for our free Indy100 weekly newsletter For the uninitiated, wormholes can be described as spacetimes in which a “kind of tunnel exists connecting distant parts in the universe”. The main problem with them is… they don’t actually exist. At least not in any tangible way. As Drs Eric Christian and Louis Barbier put it in an explainer for NASA: “Wormholes are allowed to exist in the math of ‘General Relativity’, which is our best description of the Universe. “Assuming that general relativity is correct, there may be wormholes. But no one has any idea how they would be created, and there is no evidence for anything like a wormhole in the observed Universe.” Still, numerous experts in the field of gravitation and general relativity have spent years or even decades working on them, including Stephen Hawking in his time. For their paper, Frolov, Krtouš, and Zelnikov explored what is known as a ring wormhole, which was first described in 2016 by theoretical physicist Gary Gibbons, of Cambridge University, and Mikhail Volkov of the University of Tours. Unlike the spherical contortions of spacetime we might attribute to black holes, the ring wormhole proposed by Gibbons and Volkov connects sections of the universe (or, indeed, different universes) which are generally described as “flat”, as ScienceAlert notes. Ring-shaped masses could potentially create some pretty remarkable distortions in what would otherwise be flat spacetime if you consider how their electrical and magnetic fields might interact. And so Frolov, Krtouš, and Zelnikov decided to consider two types of such wormholes: “a wormhole connecting to flat spaces; and a wormhole connecting two distant domains in the same space”. For the latter, they concluded that if a “massive thin shell” surrounded one of the mouths of the ring wormhole, a “closed timelike curve” would form. This, as the name suggests, would mean that any travelling object (or ray of light) would come back to the exact same point whence it began. In other words, you could travel in space and time and return to your point of departure. The most exciting aspect of ring wormholes, as the authors point out is that: “For the ring wormhole an observer passing through it moves in a flat (or practically flat spacetime), while in the case of ‘standard’ (spherical) wormholes he/she should pass a domain filled with the matter violating the null energy condition.” Even without knowing what the “null energy condition” is, you can appreciate that the first option sounds a lot simpler. Now, before you start calling yourself Marty McFly or making a list of all the past mistakes you’d like to correct, we should stress that we’re a long way off seeing the creation of a bonafide, buckle-your-seatbelt time machine. But at least, thanks to the efforts of experts like Frolov, Krtouš, and Zelnikov, we’re at least one step closer to going back in the future. Have your say in our news democracy.

Twitter has lost its head of trust and safety amid ongoing criticism of the site’s protections against harmful content. Ella Irwin said on Thursday that she had stepped down as the company’s head of trust and safety, a key role in ensuring that Twitter is able to avoid showing dangerous content and compromising relationships with advertisers. Ms Irwin, who joined Twitter in June 2022, took over as head of the trust and safety team in November when previous head Yoel Roth resigned. She oversaw content moderation. An email to Twitter returned an automated reply with a poop emoji. Irwin declined further comment and Musk did not immediately respond to a request for comment. Irwin’s departure comes as the platform has struggled to retain advertisers, with brands wary of appearing next to unsuitable content. Musk announced earlier this month that he hired Linda Yaccarino, former NBCUniversal advertising chief, to become Twitter‘s new CEO. Fortune earlier reported that Irwin’s internal Slack account appeared to have been deactivated. Since Musk’s acquisition, Twitter has cut costs dramatically and laid off thousands of employees, including many who had worked on efforts to prevent harmful and illegal content, protect election integrity, and surface accurate information on the site. Musk has promoted a feature called Community Notes, which lets users add context to tweets, as a way to combat misleading information on Twitter. The company is also facing increasing scrutiny from regulators over its moderation efforts. Twitter withdrew from a voluntary agreement with the European Union to tackle disinformation, while saying it was committed to complying with upcoming internet rules in the EU. EU industry chief Thierry Breton warned Twitter last week that it would not be able to avoid legal obligations in the EU after quitting the voluntary agreement.

PITTSFORD, N.Y. (AP) — All those injuries that made Brooks Koepka wonder if he was still among golf’s elite were put to rest Sunday at Oak Hill when he beat the strongest field of the year and won the PGA Championship for his fifth major title.

Fantasy Premier League managers get one free transfer a week to make but with the competition in full flow some may have saved up for two free switches to their teams while others will be considering a four-point hit or more to maximise the chances of success. Here are five players who we think are worthwhile considering as the Premier League heads into the new gameweek, judging by upcoming fixtures and individual player form. Destiny Udogie, Tottenham - Defender (4.7) In his last three matches, the defender has recorded 22 points, making him a good option for those looking to move some things around and free up some money in their team. He has already notched up two assists this season, and Spurs’ next match is against Sheffield United, although rotation may be expected with Liverpool and Arsenal to come afterwards. After those two difficult matches however it is a good run for Tottenham going forward. Udogie could be a high-scoring option, especially if there is flexibility to rotate him out for the difficult matches. Bryan Mbeumo, Brentford - Midfielder (6.8) Mbeumo has enjoyed an impressive start to the season, averaging 8.2 points per match and has already scored four goals. While Newcastle away next week might be a tough ask for Brentford, there are matches against Everton and Nottingham Forest afterward. While not necessarily a cheap option, he can offer a more affordable option than other midfielders. Julian Alvarez, Manchester City - Forward (6.7) Forwards, and in particular Manchester City forwards often come with a high price tag, which makes Alvarez a relative bargain. He has averaged seven points a match, scoring two goals and recording three assists, especially during his 14 points during City’s dominant 5-1 win over Fulham at the weekend. With City’s next three fixtures coming against West Ham, Nottingham Forest and Wolves it could also be the ideal time to add in some extra support. James Maddison, Tottenham - Midfielder (7.8) Tottenham have won their last three matches, so on paper they look strong and it’s the right time to add their players to a squad. Maddison has been outstanding since joining the club, averaging 7.2 points a match, scoring two goals and providing two assists. It is a high price tag but could be worth the investment in the long run. Alphonse Areola, West Ham - Goalkeeper (4.1) Areola was known for his shot-stopping abilities when he was at Fulham, and seems to have taken over the number one spot at West Ham this season. As goalkeepers go he is a cheap option at just 4.1 million but he has averaged five points a match, including a memorable 10 points during the second gameweek against Chelsea. At a minimum, he is guaranteed to play every week, and with West Ham’s impressive start to the season he could be a good addition if the rest of your budget is allocated in other positions. The Hammers face Man City at home and Liverpool away next, but Areola could be a cheap option to pair with a more expensive goalkeeper who has difficult fixtures in gameweeks seven and eight, with the potential to score points against Sheffield United at home and Newcastle at home.
