Elon Musk has posted a series of explicit tweets about Mark Zuckerberg, including This week, Mr Musk tweeted that “Zuck is a cuck”, and followed it up with a post in which he proposed a “literal dick measuring contest”, alongside a ruler emoji. On Monday, he then responded to a post in which another user speculated that Mr Musk would lose such a contest. “This would so inappropriate & lacking in dignity … let’s do it!!!” Mr Musk wrote in a reply. It is just the latest in Mr Musk’s often intense responses to the launch of Threads, a Twitter competitor launched by Mr Zuckerberg’s company, Meta. He has also threatened to sue Meta over the similarities with his app, suggested that it is falsely joyful, and boosted posts that suggested the launch of Threads had actually helped the launch of Twitter. Mr Musk has also attempted to suggest that Twitter is both free of censorship and the pressure to be happy. “You are free to be your true self here,” he wrote in his most recent post on the topic. He has also promoted a post from Twitter’s chief executive, Linda Yaccarino, in which she suggested that Threads’ success had actually helped Twitter’s growth. “Don’t want to leave you hanging by a thread… but Twitter, you really outdid yourselves!” she wrote. “Last week we had our largest usage day since February. There’s only ONE Twitter. You know it. I know it.” It is not clear how much the launch of Threads has boosted or hurt Twitter’s usage. But external estimates suggest that the site’s usage is “tanking”, according to experts. Meta’s Threads surged past 100 million signups in its first five days, according to Mark Zuckerberg. In doing so, it became the fastest online platform to hit the milestone, overtaking ChatGPT. The app has been setting new records for user additions since its launch on Wednesday, with celebrities from Jennifer Lopez to Kim Kardashian joining the platform seen as the first serious threat to the Elon Musk-owned microblogging app. Twitter has responded by threatening to sue Meta over the app, alleging that the social media behemoth used its trade secrets and other confidential information. That claim, legal experts say, could be hard to prove. Threads shares some resemblance to Twitter, as do the numerous other social media sites that have cropped up in recent months. It allows posts that are up to 500 characters long and include links, photos and videos of up to 5 minutes. The app’s sprint to 100 million users was much faster than the two months OpenAI-owned ChatGPT took in January, which had made it the fastest-growing consumer application in history, according to a UBS study. Still, Threads has some catching up to do. Twitter had nearly 240 million monetizable daily active users, according to a company statement in July last year.

Earth has been hit by a blast from a dead star so energetic that scientists cannot explain it. The burst of gamma rays, originating in a dead star known as a pulsar, is the most high energy of its kind ever seen. It was equivalent about ten trillion times the energy of visible light, or 20 tera-electronvolts. Scientists are unable to explain exactly what kind of a scenario could lead a pulsar to emit such intense energy, and the researchers behind the breakthrough say that it “requires a rethinking of how these natural accelerators work”. Scientists hope that they can find yet more powerful energy blasts from pulsars, with a view to better understanding how they are formed. Pulsars are formed when a star dies, exploding in a supernova and leaving behind a tiny, dead star. They are just 20 kilometres across, and spin extremely fast with a powerful magnetic field. “These dead stars are almost entirely made up of neutrons and are incredibly dense: a teaspoon of their material has a mass of more than five billion tonnes, or about 900 times the mass of the Great Pyramid of Giza,” said Emma de Oña Wilhelmi, a scientist at the High Energy Stereoscopic System observatory in Namibia that detected the blast. As pulsars spin, they throw out beams of electromagnetic radiation, throwing it out like a cosmic lighthouse. That means that someone in one spot – like the Earth – will see the radiation pulses flash in a regular rhythm as they spin past. The radiation is thought to be the result of fast electrons that are produced and thrown out by the the pulsar’s magnetosphere, which is made up of plasma and electromagnetic fields that surround the star and spin with it. Scientists can search the radiation for different energy bands within the electromagnetic spectrum, helping them understand it. When scientists previously did that with the Vela pulsar examined in the new study, they found that it was the brightest everseen in the radio band, and the brightest persistent source in the giga-electronvolts. But the new research found that there is a part of the radiation with even more high energy components. “That is about 200 times more energetic than all radiation ever detected before from this object,” said co-author Christo Venter from the North-West University in South Africa. Scientists don’t know exactly how that could happen. 
“This result challenges our previous knowledge of pulsars and requires a rethinking of how these natural accelerators work,” says Arache Djannati-Atai from the Astroparticle & Cosmology (APC) laboratory in France, who led the research. “The traditional scheme according to which particles are accelerated along magnetic field lines within or slightly outside the magnetosphere cannot sufficiently explain our observations. “Perhaps we are witnessing the acceleration of particles through the so-called magnetic reconnection process beyond the light cylinder, which still somehow preserves the rotational pattern? But even this scenario faces difficulties to explain how such extreme radiation is produced.” An article describing the findings, ‘Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts’, is published today in the journal Nature Astronomy.
