Real

Images no longer mean that something was real. Welcome to the era of permanent visual doubt

by

There was a time, probably less than a year ago, when you saw a picture on the Internet and simply believed it. You didn’t stop to analyze it, or look for its context. You didn’t think “is it real?”, you simply processed it as information, and moved on. That moment will not return. We no longer talk about deepfakes very hardworking people who deceive some journalist (of that We already warned seven years ago). We are talking about something much more banal and therefore more devastating: Your brother-in-law can create a photo in three seconds of you, completely drunk, at a bachelor party you never went to. Your ex can fabricate a photo of you in a pose you never had. A student can generate a compromising image of his or her teacher during the transition between classes. The question is no longer whether the technology is good enough. It is perfect, we are seeing it with several tools and with the recently launched Nano Banana Pro to the head. In fact, it’s too perfectto. And perhaps for the first time, technical perfection has come before social perfection. Who is capable of seeing the photo on the right and assuming that neither the woman nor the waiter nor the bar actually exist? Let’s go having to learn to do something different from what we have been doing all our lives: learn not to be able to trust our eyes. Our entire epistemology—from court testimony to family photo albums—rests on a simple principle: seeing is a way of knowing. Not perfect, but sufficient: For 300,000 years of human evolution, if you saw a tiger, there was a tiger. For 199 years of photography, if you saw an image of a tiger, someone had been close to a tiger. That chain just broke. And it doesn’t break little by little, with warnings and an adaptation period. It breaks suddenly, on any given Tuesday, when you discover that the viral photo you shared was fake and you ate it without hesitation. Or worse: when you discover that everyone has assumed that the real photo you shared is actually fake. What we are losing is not the ability to distinguish what is real from what is fake. That got complicated a long time ago. What we are losing is something more primary: the possibility of operating under the assumption that the visual is, by default, a reasonable starting point. There’s the catch. for a decade we become obsessed with fake news. We were worried about Russian bots, troll farms or organized disinformation. All that was industrial. It cost a lot of money, left footprints and required coordination. What Nano Banana Pro brings is different. It is artisanal misinformation, common at home. You don’t need an authoritarian government or a budget behind it. You just need a smartphone, whatever it is. We could combat industrial misinformation with fact-checkers and media literacy. How do you combat the fact that each person is now a printing press for alternative realities? How do you verify 10 billion images daily? You can’t. The least obvious consequence is the most devastating: we are going to beg for a lock next to our real photos. If anyone can make any image, only those with verifiable certification will matter. Encrypted metadata, digital chain of custody, institutional authenticity seals. Anything, but something. The photo without a stamp will be suspicious by default. Who is going to offer that certification? Google, Meta, Apple, maybe governments. The only institutions with resources to verify on that scale. We are going to pay them for something that has been free for two centuries: the presumption that what was photographed existed. Because the alternative – a world where no one can be sure of anything – is simply unlivable. But The worst thing is not losing confidence in the images. It is losing confidence in memory. Your brain doesn’t store experiences, it stores reconstructions. And every time you remember something, you reconstruct it with the help of fragments: smells, emotions, images. Photographs have been crutches for memory for decades. They consolidated the rest of the memory. And then there is exhaustion. Every image you see now requires a little evaluation. Is it real? Do I verify it before sharing it? Will I look like a tolili if I send her to the group? Another tab for our internal CPU. Our parents never had to do this cognitive work. We are going to spend the rest of our lives in suspicion mode. Not because they are cynical, but because they are rational. That permanent suspicion has a cost. In attention, in mental energy. Perhaps in a capacity for wonder. In the possibility of seeing something extraordinary and simply believing it. Never again. There is hardly a solution for this: You can’t train an AI to detect AI-generated images perfectly: it’s an infinite arms race. Each detector upgrades the generators. Each generator improves the detectors. Each higher wall is an incentive to lengthen the pole. You can’t educate people to “think critically” on each of the thousands of images it processes per day. We don’t have bandwidth. and nor you can legislate the problem because technology is faster than the law and more accessible than any prohibition. The only thing left is adaptation. Cultural and psychological. Our grandparents trusted what they saw. We trusted what was photographed. Our children are not going to trust anything that does not come certified. Maybe the blockchain It was also invented for this. AND When everything needs verification, nothing can be spontaneous. When every image is suspect, none is memorable. When reality requires constant authentication, we stop inhabiting it naturally. Photography died the day it became indistinguishable from the imagination. We will continue taking photos and we will continue seeing them. But They will no longer do what they did for two centuries: tell us what was real. Welcome to the era of permanent visual doubt.

how to produce real bacon without having to kill it

by

Imagine biting into a piece of golden, juicy bacon with that unmistakable pork flavor, only no pig has had to die for you to enjoy it. And no, I’m not talking about tofu, seitan or another plant replica: it’s real bacon, made from pig cells that still belong to a living animal. A concept as disconcerting as it is unique that is already served in a small restaurant in California. The first cultured pork fat. The startup Mission Barns has become the first company approved to market cultured animal fat and the third to receive regulatory approval for a cell-based food in the United States. In March obtained FDA validation and, shortly after, the support of the Department of Agriculture (USDA)which allowed him to start selling his product on a limited basis. As TechCrunch detailsit is the first cultured pork fat in the world authorized for human consumption. Until now, only UPSIDE Foods and GOOD Meat They had obtained similar approvals, but only for chicken. With this decision, Mission Barns inaugurates a new category: real pork fat without slaughtering it and capable of being converted into bacon, sausages, meatballs or salami. Real meat without slaughter. Cultured meat—also called in vitro meat or clean meat— is not a plant imitation, but biologically real meat obtained without resorting to animal breeding and slaughter. In this case, the animal has its own name: Dawn, a Yorkshire sow who lives in a sanctuary in northern New York. According to Futurismthe sample is taken painlessly and does not alter your daily life. Its fat cells are grown in a bioreactor with plant nutrients and adhere to a porous structure designed to mimic natural pig tissue. After two weeks, the culture generates real pork fat, which is mixed with vegetable proteins – pea, wheat or bean – to replicate the texture of bacon, sausage or meatball. As explained in Gristthe tastings carried out by the company demonstrate by its flavor and texture that it is meat in biological terms, but without animal sacrifice. So, Is it a vegetarian option? The arrival of this technology reopens a great ethical debate. Different studies indicate that pigs They are “very social” animals.capable of feeling fear, stress and complex emotions, and They are considered the fifth animal smartest in the world. Being able to obtain meat without sacrificing them represents, for many, a moral change of enormous scope. That is precisely the reason why, according to The Guardiansome vegetarians have begun to try cultured meat: by eliminating the violence of the process, the ethical barrier that justified not eating meat disappears. Others, however, are hesitant and wonder if consuming “suffering-free meat” fits with their reasons for abandoning animal products in the first place. A global phenomenon: from California to San Sebastián. The race for cultured meat is global. It is not something from the United States, also in Japan either Netherlands They are already developing lines of cultured beef, chicken or fish. And in Spain, BioTech Foods leads the push from the Basque Country, where it is building the largest cultured meat plant in southern Europe in San Sebastián, with plans to operate in 2032. The immediate obstacle is regulatory, since the European Food Safety Authority (EFSA) has not yet approved its commercialization. Forecasts. Meanwhile, Dawn—the pig that gave rise to this bacon—continues in her sanctuary, oblivious to everything, seeking the sun and letting her belly be scratched. That fat can come out of it for thousands of servings without your life changing poses an unprecedented image in the history of food. The question is whether society is prepared to take it on. cultured meat promise reduce emissions, suffering and costs; his detractors they talk about an industry still expensive and difficult to climb. Between both visions, the final decision will fall to consumers: whether they accept that the meat of the future can grow in a bioreactor.

We have been talking about railguns for years without seeing their real damage. Japan just showed an image that says it all

by

Japan is going through one of the most crucial transformations in recent decades: that of its rearmament. It is its most aggressive defense policy since Second World Warand the Ministry of Defense justifies because we are in the “most severe and complex phase of the last 80 years.” And there is nothing that better exemplifies Japanese rearmament than a cannon that, until not long agoit was science fiction material. The electromagnetic cannon. Reconfiguration. Starting in the 1990s, Japan stopped investing significantly in its Self-Defense Forces. He economic bubble burstthe “lost decade” and demographic difficulties implied that the military spending of 1% of GDP that they adopted after the Constitution of 1947 would be maintained. In 2023, things changed. As a result of geopolitical complexity, they decided that they would invest 2% of their GDP in rearmament. In figures, we are talking about about 271,000 million euros until 2027, but recently The target has been brought forward to March 2026. This reconfiguration will manifest itself in four dimensions: the aforementioned increase in military spending, the restructuring of the Self-Defense Forces, a relaxation of restrictions on the export of weapons and the expansion of long-range offensive capabilities. That’s where the railgun comes into play. Electromagnetic cannon. Like gunpowder, it fires a projectile that gains speed as it passes through a barrel. However, it uses electricity instead of gunpowder. Two metal rails form a circuit that, when closed by the projectile, generates an intense magnetic field. This produces a beastly force that propels the projectile at high speed, allowing hypersonic, precise and long-range shots. This speed would allow that would travel without detour even in the most unfavorable weather conditions. Japan has been investing in this field since mid of the 2010s, and a few weeks ago, the Japan Acquisition, Technology and Logistics Agency (ATLA) performed the first proof documented firing of a naval electromagnetic cannon at a real ship. Mounted in it JS Asuka test shipthe prototype is a cannon of 40 millimeters in caliber and six meters in length. It requires four huge energy containers to power the weapon and the projectiles used were small missiles of about 320 grams, stabilized by fins and without an explosive head. There is no need for an explosion: upon reaching those 2,300 meters per second, the kinetic energy is comparable to that of a 1,000 kilo car crashing into something at 140 km/h. Success. During them, the system achieved a record by firing projectiles at a speed of 2,300 meters per second. It is a speed of Mach 6-7, but in addition, they also pushed the useful life of the barrel to the limit. The estimate was about 120 shots, since it was established in previous phases of the investigation, but they got perform more than 200 shots without the system failing. ATLA had conducted open sea tests before, but never against a real target. And although they had already commented that the tests were a success, now they have shared photographs in which you can see the holes left by these projectiles. The target ship was in motion, but due to the enormous speed and stability of the projectiles thanks to the enormous power of the system, the entry holes allow an almost perfect view of the “cross” left by the projectile passing through the hull. Challenges. Now, understanding how a railgun works is easy, but executing it is extremely complex. It is a brutal technical challenge due to several factors: The stability of the barrel: the system generates tremendous heat, so dissipation systems must be effective enough not to compromise the integrity of the barrel. Wear and tear not only affects the speed and accuracy of the projectile, but can cause accidents on the boat itself. The energy: since it requires so much electricity to operate, it must have storage systems large enough to allow it to operate with the necessary power and during intense fire sessions. Miniaturization of the system: these cannons are extremely large and, although ATLA has managed to contain it quite a bit, mounting them on ships is not easy due to both the length of the cannon itself and the set of batteries required. Integrating a railgun into a ship is not easy. Perspectives. Currently, ATLA is working on evolving a system which might not be as far from the action as was thought a few months ago, and this miniaturization would allow it to be mounted on other types of vehicles, in addition to ground defense lines. But apart from as a weapon, the agency has mentioned that the concept of electromagnetic acceleration could be applied to other areas. For example, to the “mass throwers” ​​that would allow launching materials electromagnetically in space transportation. The problem is that other challenges are added, such as the imperative need to calculate the trajectory millimetrically or develop recovery methods for these goods. USA and China. And, although it may seem like another test of weapons, what Japan has achieved is a milestone. After fifteen years of research and some 500 million dollars invested in the technology, The United States left in 2021 the development of electromagnetic railguns (although they are now with larger versions). Japan has persevered and its testing demonstrates that the system can be viable in a real-world context. And another that has continued to develop this technology is China. They are keeping it more secret, but we have already seen images of Chinese ships with an electromagnetic cannon and power containers on the front. And that, precisely, it was these two countries that They are taking steps forward when developing this technology It’s not a coincidence. They are both engrossed in technological warbut also in a escalation of military tension that has been going on for months and that is leading both countries to accuse each other of invading their respective territory.

The bloodiest scene in the history of cinema left its protagonist in shock. 50 years later we know it was real

by

Stephen King told that, for him, his Carrie It was like a pig taken to the slaughterhouse, and the blood of the animal reinforced the metaphor anticipating the massacre that would follow. Hence when the novel became a film, the most recognizable scene was the most visceral, organic and unpleasant of all. A gore moment that became celluloid history. The blood that changed terror. The Legend of Carrie (the movie) is born at the moment when a thick mixture of corn syrup and red food coloring falls on actress Sissy Spacek, a moment that has transcended horror cinema itself to become a cultural icon. The construction of the scene (the coronation interrupted by the explosion of humiliation and fury) concentrates the essence of a film that turned the artificial into something emotionally real. He Karo syrupheir to decades of cinematic experimentation with fake blood, here acquired an unexpected meaning by becoming the visual and psychological trigger for Carrie White’s transformation. Anniversary. Now that 50 years have passed since the original film, Spacek has remembered that that substance “warm as a blanket” in the first seconds soon became an exhausting, sticky and repetitive experience, forcing her even to sleep with the bloody suit so as not to have to reproduce the makeup application. But precisely that physical surrender, with its almost immobile and tragic presence under the weight of the thick liquid, is what granted to the plane that kind of mythical quality: the border between artifice and emotion is erased, leaving only the fixed gaze of a broken teenager who feels, for the first time, that the whole world is laughing at her. The infernal filming of a scene. The Independent said It’s been a few years since the prom sequence required almost surgical precision. Although the rest of the scene required more than thirty takes, the exact moment of the blood spill could only be filmed once or twice due to the impossibility of cleaning and recomposing the set. Spacek even accepted that it was her own husband who operated the cube mechanism to ensure that the fall was perfect, knowing that her interpretation would depend on how she received that hit of red viscosity. The fake blood was a physical enemy but also a dramatic element on which the story completely depended: its texture, shine, the way it adhered to the actress’s body and soaked her dress, everything contributed to giving the impression that something irreversible had happened. In fact, many of the scenes we saw ended up being very real: a stage that ended up accidentally burning, a team evacuated while the director I asked to keep rolling and injuries such as the perforation of an actress’ eardrum during the attack of the launched hose telekinetically by Carrie. What should have been millimeter choreography became an almost ritual experience, in which fire, destruction and general chaos seemed to respond to the internal logic of the film itself. The unexpected myth. Despite initial doubts, the rejection of critics who considered it a sensationalist spectacle and the fact that even the name of Stephen King appeared poorly written In the first previews, Carrie ended up transforming into a phenomenon. Its mix of operatic stylization, black humor, adolescent cruelty and symbolic violence connected with a much wider audience than expected, inaugurating a type of youth horror cinema that is still alive several generations later. For King, a small-town teacher who had thrown away the first pages to the garbage can before being rescued by his wife, the film marked the beginning of a hyperbolic race. For director Brian De Palma, it was the definitive consolidation of his baroque style, obsessed with the gaze, visual manipulation and expressive excess. A unique role. Of course, for Sissy Spacek, work meant an Oscar nomination and lasting recognition for a performance that combined absolute vulnerability and unleashed rage. On a personal note, I would say that none of the later remakesreinterpretations and adaptations managed to capture that mixture of innocence, evil and contained tragedy that the original became its hallmark. The validity of a story. The truth is that with the passing of the decades, Carrie has not lost strength. Quite the contrary, its contemporary reading resonates in a world where school violence, public humiliation and the feeling of youth isolation are part of the collective imagination. the movie speaks of the ritualized cruelty of adolescence, of vulnerability to changes in the body and of a universal feeling of maladjustment that Spacek described a few days ago on CNN like that “wounded teenager that we all have inside.” The combination of emotional realism and the tone of a dark story, almost biblical in some passages, turns the story into more than just an exercise in terror. The presence of a fanatic mother, the brutality of her classmates, and Carrie’s own inability to understand what is happening to her allow the story to oscillate between melodrama, religious parable, and Greek tragedy. The visual references, the use of color and the stylization of the final climax consolidate an imaginary that continues to define how psychological horror is filmed. in adolescence. The weight of artifice. Five decades later, Spacek’s memory of filming it’s contradictory: the physical hardness of the process, the exhaustion of wearing hardened layers of corn syrup, the extreme discomfort of the long days and, at the same time, the privilege of having worked on a project where each member of the team was dedicated to something that they did not know would transcend. That mix of technical suffering and unfiltered creativity explains why the blood scene has become an immutable symbol of horror cinema. What began as a practical necessity (creating cheap, realistic, and manageable gore) ended up leaving an indelible mark on how emotional violence is portrayed on screen. Perhaps for this reason, Carrie remains a most accurate study in fragility, repressed rage and the devastating power of humiliation, but also as a demonstration that even a sticky, artificial substance can, in … Read more

The enormous Mayrit tunnel boring machine on Metro L11 is already in Madrid. Now comes the real challenge: putting it together piece by piece

by

In Madrid there are already the pieces of one of the largest machines that will work in the city’s underground in the coming years. It is about Mayritthe EPB tunnel boring machine 98 meters long and 1,500 tons in weight whose transport started in Germany, continued along the Rhine to Rotterdam and continued by boat to the port of Santander. After that journey, a special convoy has completed more than 450 kilometers by road to take its modules to the future Comillas station, where it will prepare to excavate the new section of Line 11 between Plaza Elíptica and Conde de Casal. The work on which Mayrit will work is part of a broader intervention that the Community of Madrid describes in 2025 as the largest expansion of the Metro network in the last decade. Official data published in November put progress at 34% and maintain a budget of 518 million euros to complete the new section and the planned stations. The regional government maintains the year 2027 as a reference to close this phase of the project. Mayrit is already in Madrid: one hour left to convert its parts into a single operational machine When dealing with a machine of this size and complexity, each phase of the process requires precision that goes far beyond conventional engineering. Mayrit’s journey towards Spain began long before it appeared on the road: it started in Schwanau, the German town where Herrenknecht completed its manufacturing after about 20 months of work. There, more than a thousand kilometers from Madrid, the tunnel boring machine It was assembled for the first time in June 2025 to carry out initial verifications. This assembly showed the magnitude of the next step: converting the machine into a set of parts capable of traveling around Europe without risks. Disassembling it was not a quick procedure. For the next two months, Herrenknecht teams dedicated themselves to separating each module following a sequence calculated to the millimeter. The result was a set of sections ready to begin an international tour. The disembarkation in the port of Santander marked the beginning of the last stage of Mayrit’s journey, a phase that requires coordination very different from that of river and maritime transport. The pieces arrived distributed in separate shipments and were transferred to prepared platforms, a process that is carried out with specialized equipment to avoid any unexpected displacement. The organization of the road transfer incorporated common protocols in special transport, with large-tonnage vehicles escorted by technical teams in charge of checking clearances, turning radii and urban accesses. The authorities confirmed that the advance was carried out mainly at night to reduce interruptions and facilitate maneuvers in the most delicate sections of the route. The arrival in the Comillas area required a final deployment of personnel and machinery to accommodate each piece in the work area, where the assembly phase that will transform this set of modules into a single operational tunnel boring machine is already awaiting. The arrival of the pieces also marks the beginning of a phase that, according to forecasts distributed between June and November 2025, can extend until March 2026. Assembling a TBM requires joining modules in a strict order, connecting hydraulic and electrical systems, and performing tests that are concentrated between late January and February. It is a sequential process that is not resolved in a few days and that determines the date on which the machine will be able to start digging at the beginning of March. The official documentation describes Mayrit as an EPB machine adapted to the geotechnical characteristics of the layout. Its operation is based on maintaining a balance of pressures that prevents unwanted movements on the surface, especially relevant in urban environments. To sustain this process, shifts of specialists are involved who manage the control and evacuation systems of the excavated material. The expected performanceclose to 15 meters per day, will be decisive in setting the pace of mechanized advance. Comillas will be the point from which Mayrit will begin the mechanized sectionaccording to the forecasts that the Community of Madrid has been detailing since June 2025. From there it will advance to Conde de Casalwhile in parallel the manual excavation of about 700 meters towards Plaza Elíptica progresses, started in September with a performance of close to 50 meters per month. The beginning of the excavation will mark the jump between the preparatory work and the actual progress of the tunnel that will transform this section of Line 11. With each meter excavated, the planned layout will get closer to its final shape and will allow the progress of the project to be measured more clearly. It is a significant element within regional planning to reinforce mobility in one of the areas with the most demand on the network.

“The real winners of the AI ​​race will be the electricians or plumbers”

by

The conversation about the future of work is taking an unexpected turn conditioned by the progressive incursion of AI into administrative positions, especially among the youngest who see the old promise of a prosperous job future after college. Influential voices in the development of AI, such as Mark Zuckerberg or Mark Chenthey are showing the value devaluation of university degrees. Jensen Huang has gone a step further by pointing out that most of the future economic opportunities could arise from traditional professions more than pure university careers. “The millionaires of the future will be electricians or plumbers,” said the millionaire in an interview for the british Channel 4 News. The winners of the race for AI. Jensen Huang, CEO of the main producer of AI chips, pointed out the significant imbalance in the current labor market, in which there is enormous offer of university graduatesbut a great shortage of qualified labor in traditional trades such as carpenters, electricians, plumbers or bricklayers. According to this shortage, it has made their jobs much more difficult. best rated and salaries could double in a short time. “The big winners in the AI ​​race will be electricians and plumbers,” said the NVIDIA CEO. Huang highlighted that, although these professions were not directly related to the development of AI models, they were related to the construction and maintenance of the data centers that support these technologies. “Whether you are an electrician, plumber or carpenter, we will need hundreds of thousands of them to build all these factories and the specialized crafts sector of all economies is going to experience a boom,” the manager stressed. Traditional jobs versus AI. One of the great advantages of traditional trades over many so-called “white collar” jobs is their limited exposure to AI automation. Furthermore, in other interventions, Huang has pointed out: “As we speak, AI has no chance of doing what we do,” stated the CEO of NVIDIA during a conference in Mumbai. To a greater or lesser degree, all positions with administrative burden or repetitive routines are susceptible to automation of all or part of their work. It is something that is already beginning to be observed with a reduction of junior positions in the main consulting firms, where AI is replacing recent graduates in basic tasks such as reporting or programming assistance. On the other hand, jobs in the manufacturing industry or traditional trades are not feeling the same pressure because, at the moment, an AI cannot fix faults in the electrical installation of a house. AI can’t build your house. Even though you may currently have a waiting list of more than six months To request a quote for a bathroom or kitchen renovation, NVIDIA’s concern about the lack of qualified labor is more related to the deadlines in the construction of its data centers. According to a report McKinseythe industry is projected that global capital spending on data centers will reach $7 trillion by 2030. That’s a lot of processors waiting to be sold. The problem is that, just like renovating your bathroom, without enough manpower Construction deadlines are longer than expected. As and how I collected FortuneLarry Flink, CEO of BlackRock, was also concerned in that regard, noting that the workforce to build the data centers they needed had been dangerously reduced following Trump’s anti-immigration policies. “I’ve even told members of Trump’s team that we’re going to run out of electricians, which we need to build AI data centers. We just don’t have enough,” declared the manager at a recent conference. In Spain they also bet on traditional professions. In Spain, the media millionaire José Elías, CEO of the La Sirena supermarket chain and president of Audax Renovables, has been giving a clear and forceful message: “Artificial intelligence is going to take over 80% of office work,” and that is going to change everything. But not for manual trades. On the contrary, those practical and physical jobs, which many today despise, will be the ones with the most opportunities and the best salary.” “They will end up charging 50, 60 or 200 euros per hour”highlighted the Catalan millionaire in an interview. In addition, he points out that these jobs offer greater growth prospects and professional stability. “A lawyer from a large firm who works long hours does not earn more than an electrician. Or someone from a Big Four audit who works 17 hours a day does not live better than an electrician either,” he explains. “An electrician works nine hours and one is having breakfast. I don’t know any electrician who doesn’t have an apartment and if you’re good and don’t get paid well, raise your hand and tell the boss ‘Hey, I’m thinking about starting to send resumes,’” explains José Elías in one of your videos.

China’s “sorpasso” is now a real possibility

by

2025 has been a lost year for NASA. No rockets have exploded, no spacecraft have crashed, but political instability, lack of leadership and budget wars have decimated the morale and operational capacity of the US space agency. The most absurd thing of all? self-inflicted harm has had the opposite effect whom the United States government was looking for. Nobody at the wheel. It all began on January 20, 2025, when Biden-era administrator Bill Nelson resigned as head of NASA. Janet Petro, director of the Kennedy Space Center, took over as acting administrator. In his six-month term he dedicated himself to abide by Trump’s divisive policiesstarting with eliminating the space agency’s Diversity and Inclusion office. donald trump had nominated for the permanent position of administrator to the young billionaire Jared Isaacman, who flew into space twice with SpaceX. Isaacman, who was seen as a commercial sector accelerationistpassed his confirmation hearing in April 2025. Everything seemed done. However, on May 31, shortly before Trump will exchange insults with Elon Muskthe White House abruptly withdrew his nomination. The official reason, published by Trump himself in Truth Social, was Isaacman’s “prior associations,” particularly his donations to Democratic candidates. The Duffy era. NASA was left adrift. On July 9, Trump named his Secretary of Transportation, Sean Duffy, as acting administrator. Duffy, a former congressman with no aerospace experience, kept his Cabinet position while running NASA, and is said to have came to maneuver to integrate the historic space agency under the Department of Transportation. But Sean Duffy’s stellar moment occurred on October 20, when he set the goal of returning to the Moon while Donald Trump was president. In order to land astronauts on the lunar surface before China does so for the first time in 2030, Duffy reopened HLS contract that NASA had granted to SpaceX. Other companies such as Blue Origin and Lockheed Martin will compete with SpaceX’s Starship to transport astronauts from lunar orbit to the surface of the Moon in the first manned lunar landing since the Apollo era. Life takes a thousand turns. In a twist that well illustrates NASA’s lost year, and despite Duffy’s efforts to show off to his president, on November 4, Trump reappointed Jared Isaacman as administrator. The timing coincides with an improvement in Elon Musk’s relationship with Donald Trump, suggesting that donations to Democrats did not have as much to do with Isaacman’s truncated career as the Elon-Trump feud did. But even as NASA’s power vacuum nears its end, the agency faces even worse problems. The White House budgets for 2026 included a 24.3% cut to the space agency’s overall funding, including a 47% cut to the scientific budget. The lack of approval of budgets has also, ironically, had a catastrophic impact for the agency: 15,000 NASA employees (85% of the staff) were suspended without pay due to the government’s “shutdown.” The shutdown has delayed all kinds of developments, including the lunar program and the Mars sample recovery mission, in which NASA is in direct competition with China. Meanwhile, China. NASA’s comings and goings have allowed the Chinese space agency to close the gap. After becoming the first country in the world to bring back samples of the far side of the Moon with the Chang’e-6 missionChina is on track to become the first nation to bring samples from Mars with the Tianwen-3 mission. The great irony is that, with NASA’s lost year, it is also beginning to be very feasible that a Chinese astronaut will set foot on the Moon before the next American moon landing occurs, which the White House wanted to avoid with its scientific budget cuts and its improvised leadership changes. The “sorpasso” is no longer a distant prediction. US inaction in 2025 has helped put China on that trajectory.

The Star Destroyer is the terror of Star Wars. But as one fan has calculated, building it in real life wouldn’t be cheap.

by

‘Star Wars’ is full of iconic ships. From the Millennium Falcon and its Kessel Corridor in just 12 parsecs to silhouettes identifiable at a glance such as the X-Wing or the TIE Fighter. We associate ‘Star Wars‘ with frenetic combats in space, but we also have iconic mastodons, authentic galactic monsters like the unmistakable Imperial Star Destroyer. Well: now we not only know how much it impresses us, but also how much it would cost us. What is a Star Destroyer. This 1.6 kilometer long, wedge-shaped beauty exhibits measurements and characteristics that make it a mini space station of considerable power. Let’s see: Approximate mass: 40 million metric tons Engines: Three KDY Destroyer-I ion engines and Cygnus Spaceworks Gemnon-4 units Maximum speed in atmosphere: 975 km/h Hyperlight Capability: Yes, with a class 2 impeller Heavy and medium turbolasers located in batteries throughout the ship Ion cannons to disable enemy systems 30 torpedo launchers or missile slots Ability to deploy 72 TIE fighters, as well as AT-AT and AT-ST ground vehicles Estimated total crew: between 37,000 and 60,000 people It functions as a small floating city, with areas for operations, daily life, maintenance and storage So the money what. Although less monumental than the Death Star, Star Destroyers require immense resources to construct. Estimates based on scientific analysis and data from the saga and collected on the website Gamestar They suggest that building, maintaining, and even disposing of when the time comes for a single Star Destroyer could cost a fortune. Used as a basis for comparison the price it costs to build a real aircraft carrier: between 13,000 and 17,000 million dollars each. And that’s just the beginning. We’re not just talking about construction itself. Resources and construction time skyrocket when considering mass production, as the Empire deploys dozens of destroyers to maintain its dominance. In addition, training and supplying personnel generate recurring costs. And maintenance, of course: refueling, repairing war damage, technological updates and replacing parts, which requires the construction of strategic space bases. We are going in parts, breaking down this authentic black hole of pasta. The initial transport. Transporting 40 million tons of construction material to space is logistically complex and expensive. With an extremely optimistic price of 10,000 euros per ton, the initial cost would be around 400 billion euros. In the long term, the cost could be reduced to about 200 euros per kilo, equivalent to about 8 billion euros. If we talk about current technologies (that is, no teleportation or similar), the realistic cost for this volume would be around 40 billion euros. What the material costs. The construction of the Star Destroyer would likely use high-strength, low-alloy steels, the cost of which is estimated at around €90 billion. More advanced systems such as propulsion, weapons and other high-performance components would require more expensive special alloys, adding at least an additional 110 billion euros. Altogether, conservative estimated costs for materials would be around €200 billion in total. To ride. The Star Destroyer is significantly more expensive to manufacture than mere materials, as labor and countless tests can cost five to fifteen times as much. The construction cost is estimated at around 2 billion euros. Furthermore, adding the costs of research, testing, infrastructure and development, especially in new energy and propulsion systems, could conservatively add another 5 billion euros to the total budget. The invoice. In short, these gentlemen will have to go and digest: the total expense to build and maintain the imperial Star Destroyer is estimated at around 15.2 billion euros, assuming transportation costs. Without including development expenses, the cost would be around 14 billion euros. But we can go up: if additional elements such as technical reserves, energy systems, lifetime maintenance and scrapping are considered, the joke can approach 40 billion euros. To put it in perspective, the USS Gerald R. Ford aircraft carrier cost around 12 billion euros, so a Star Destroyer would cost almost four thousand times that amount.​ In Xataka | Adam Driver launched a Star Wars movie project about Kylo Ren.

The new mayor of New York is a rare bird in the US, but he has an even more unexpected facet: a shareholder of Real Oviedo

by

Among the many congratulations that Zohran Mamdani has received over the last few days, after conquering the seat of mayor of New York, there is one that stands out as unexpected: that of Real Oviedo. Yesterday the club carbayón conveyed his congratulations via It may sound strange, but it is better understood when you know a key fact: Mamdani has been a shareholder of Real Oviedo for years. To understand it you have to go back to 2012. Who is Zohran Mamdani? That question might have made sense a few years ago, when Mamdani was one of a long list of members of the Albany Assembly. Today his name is one of the most popular in the United States, even outside the political sphere. The reason: on Tuesday he beat Andrew Cuomo and Curtis Sliwa in the race for New York City Council, becoming the elected successor of Eric L. Adams and crowning a dazzling rise. Click on the image to go to the tweet. Why is it so popular? Taking into account that New York is the main city in the United States (and one of the most media-rich on the planet), becoming its mayor should be enough to gain global projection, but Mamdani stands out for something else: an unorthodox profile. So much so, in fact, that it is a rare bird in the long history of the municipality. To start with his age: he has just turned 34, making him the youngest politician to hold office in the last century. As if that weren’t enough, Mamdani is an immigrant (born in Kampala, Uganda), Muslim, made his debut in the world of rap under the name Mr. Cardamomo and defines himself as a “democratic socialist.” He is also a skilled communicator, handles himself with ease in networks and has not hesitated to run as one of the strongest voices in the opposition to Donald Trump, whom he sent a public message after proclaiming himself the winner of the municipal elections: “I know you’re watching. I only have three words for you: turn up the volume! New York will continue to be a city of immigrants, built by immigrants and driven by immigrants. And starting tonight led by an immigrant.” Click on the image to go to the tweet. And what does it have to do with Oviedo? To answer that question we have to go back to 2012, when Real Oviedo passed through low hours. In Spain the winds of recession were blowing and the club carbayón He was seen with battered accounts and confined to the Second Division Bfrom which it would still take time to come out. The club itself refers to that period, which began in 2001, as a “fight for survival”. With that backdrop, the Asturian team decided to desperately search for a capital increase to save it from the hole, an effort in which the city devoted itself and which had the support of well-known figures, such as the popular British journalist Sid Lowewho gave visibility to the campaign on social networks. The call from Lowe, a native of Archway (London), but a fan of Real Oviedo since his student years in the Asturian capital, came among others to a young man from Kampala, a football fan and with musical whims: Zohran Mamdani. At the time he was only 21 years old, but he decided to join the wave of support. On November 9, 2012, at 5:47 p.m., he responded to Sid Lowe’s request with a message posted on Twitter: “I just bought a share, am I possibly the first shareholder of the eral Oviedo based in Maine? #SOSRealOviedo.” His tweet passed without pain or glory. The message from one more fan. One more among hundreds. Things changed on Tuesday, when Mamdani became mayor of NY. Is it your only relationship with football? Mamdani is more than just a politician, former rapper and (now) elected mayor of the largest city in the United States. He is also a self-confessed soccer fan. He himself has said that he made his first steps during his student years and his Arsenal fandom. “My uncle is a fan. I had magnets of the Invincibles (the team that won the 2003-2004 First League without losing a game) on my fridge. I loved David Seaman, Sylvain Wiltord, all of them… I have gone to many Arsenal games, many with my uncle. It has been a very important part of my life,” explained recently to The New York Times. Beyond the stands or the fields, Mamdani has known how to combine his football hobby with his political side, which has led him to launch a campaign to demand that FIFA not marginalize New Yorkers in the World that will host North America in 2026 and that includes the MetLife Stadium between its stages. Their proposal is that the organizers reserve part of the tickets for residents and also offer them a discount. The objective: that enjoying the championship is not an unattainable luxury for New York families. Images | Real Oviedo and Wikipedia In Xataka | In 2017 Liverpool signed a star footballer.

Michael Burry just shorted NVIDIA. All good except because he was the one who predicted the 2008 real estate bubble

by

Michael Burry, the well-known investor and fund manager who predicted the 2008 financial crisis, has recently shown his bearish positions against NVIDIA and Palantir just after launching on social networks a warning about excess optimism in the market. Warning which the Bloomberg media has qualified ‘cryptic’, for several reasons. The movements, made known in regulatory documents filed on Mondayhave reopened the debate on whether artificial intelligence is generating a speculative bubble. What exactly has Burry done. His investment fund, Scion Asset Management, has bought put options (puts) worth $186.5 million against NVIDIA and $912.1 million against Palantir, according to mandatory filings with the SEC. These options benefit if the stock price falls. Burry also took bullish positions (calls) in Pfizer and Halliburton, two stocks that have underperformed the market this year. Why does it matter? Burry is not just any investor. Its history is marked by having bet short against the US real estate market two years before the 2008 crashenduring criticism from his investors until Lehman Brothers went bankrupt and his fund multiplied its profits. His story inspired the film ‘The Big Bet‘. Having gained that fame, when Burry bets against something, the markets pay attention, although his track record is not infallible, as he has been wrong in the past with other bubble predictions. Click on the image to go to the post The context of their movements. Days before these positions became known, Burry broke two years of silence on social networks with a disturbing message: “Sometimes we see bubbles. Sometimes you can do something about it. Sometimes the only winning move is not to play,” accompanied by an image of his character in the film. On Monday night he posted again, this time sharing a Bloomberg chart about concerns about circular financing between OpenAI, NVIDIA and other AI companies. Market reactions. Palantir shares fell more than 10% following the news, even though the company had just raised its annual revenue guidance. NVIDIA also fell by up to 2.9%. Palantir CEO Alex Karp responded in an interview with CNBC calling the idea of ​​shorting against companies like Palantir and NVIDIA, which he says are doing “noble tasks,” “crazy.” The bubble debate. For months, many investors have expressed concern about whether the AI ​​boom is being artificially sustained. Ray Dalio, founder of Bridgewater Associates, warned recently told CNBC that “there are many things that look like bubbles,” although he clarified that bubbles do not usually burst until the Federal Reserve tightens its monetary policy. According to its “bubble indicator”, approximately 80% of market gains are concentrated in large AI-related technology companies. An important nuance. It’s not entirely clear whether Burry is betting directly on the downside or whether these options are part of a more complex strategy to protect other investments. And just as share Bloomberg, regulatory filings only reflect long positions, so if you were using these puts as a hedge for other investments, we wouldn’t know. The curious thing is that its first quarter presentation did include a note explaining that puts “could be used to cover long positions”, but the third quarter presentation does not say anything about it. Scion’s recent history. This is not the first time Burry has bet against NVIDIA. During the first trimester He has already liquidated almost his entire portfolio of listed shares and bought put options against the chipmaker. However, it has also achieved success: in the third quarter it closed positions in Alibaba (with a 36.5% profit), Estée Lauder (27%), ASML Holdings (45.7%) and Regeneron Pharmaceuticals (10.8%). Canary in the mine or false alarm? The question on Wall Street is whether Burry is once again detecting a bubble before anyone else or if he is wrong this time. NVIDIA is up 54% this year until reaching a capitalization of 5 billion dollarswhile Palantir has soared 173% thanks to its expansion in AI-related businesses. Valuations are high, but both companies continue to grow and expand their business. Be that as it may, if there is a bubble, we will find out in the worst possible way: when it bursts.
