Tesla’s enormous problem in Germany has an alarming figure and a clear person responsible: Elon Musk

by

Three out of four potential buyers of an electric car reject the idea of ​​buying a Tesla. The study points to the German market, which is the first electric car market in Europe by sales volume, and explains an important part of Tesla’s failure in Europe during 2025. Three out of four. 75% of potential buyers of an electric car in Germany do not value the idea of ​​buying a Tesla car, according to a study by the German Institute of Economics in collaboration with the Technical University of Dresden. The figure, which in itself is bad, has even more meaning. And that 75% is made up of potential customers who believe it is unlikely to buy a Tesla (15%) and those who completely reject buying a vehicle from this brand (60%). The reason, as we could imagine, is not a question of competition or price. The disaster. Last year, 545,142 electric cars were sold in Germany. It was, by far, the strongest electric car market in Europe. The growth was 43.2% compared to 2024, the year in which just over 380,000 electric cars were sold. Its market share reached 19.1%, above the European average, according to ACEA. For Tesla, however, it was not a great year. In Europe, 150,504 electric vehicles from Elon Musk’s company were sold, 37.9% less than the previous year when 242,436 registrations were registered. The most problematic thing is that the company had achieved a market share of 2.3% (a good bite to eat on the electric car pie, which in 2024 was only 13.6% in the European Union. That is, almost two out of every 10 electric cars sold in Europe were from Tesla. The drop was even more pronounced in Germany. There, the drop was 48.4%, as recorded Reuters at the beginning of the year. And, with everything, It has not been its strongest percentage drop in European countries but the damage in volume is more than evident. The politics. The decision by which the Germans seem to completely reject Tesla is evident to the creators of the study: Elon Musk’s political positioning. According to the authors, political positioning influences the purchase of a car more than sociodemographic characteristics. They point out that young people, those with a higher level of education and those who live in urban areas are more inclined to purchase an electric car. In political terms, Green supporters are the most open to acquiring this technology and AfD (German far-right) voters are the least enthusiastic. On average, they say, the potential customer for an electric car has grown by over 40% and those who reject it outright have also fallen. But the problem for Tesla is that it is not attractive to either group. Among the Greens, only 10.8% value the purchase of a Tesla as their first option and the percentage grows among AfD followers to 15.2% but it must be taken into account that these voters are also less in favor of buying a car of this type. Just lose. The study concludes with a statement: Elon Musk has lost support for buying cars among progressive groups (those who buy the most electric cars or are willing to buy) and has not attracted enough conservative groups to alleviate this disadvantage. The result is a direct consequence of a year 2025 that began with Elon Musk doing a Nazi salute during Donald Trump’s takeover of the United States and which continued with a explicit support of the company’s head for AfD and other far-right parties in Europe. It must be taken into account that this type of political positioning in Germany is much more delicate than in other countries. In Germany the Nazi salute is a crime punished with a fine in minor cases but which can be grounds for imprisonment in more serious cases. Study on preferences when buying an electric car in Germany segmented by political parties. Source: German Institute of Economics The worst option almost always. The image above shows the predisposition of Germans to the type of electric car they want to buy, segmented by their origin and the political parties that these potential customers vote for. According to this data, Tesla is the last option in four of the six political parties studied, even behind Chinese cars as the first option. The latter always surpass him except among CDU and SPD voters (although in both cases a greater percentage considers it possible to buy a Chinese car over a Tesla if we add the second level of predisposition). Tesla reaps the worst results among the Greens and Linke (The Left) and the absolute rejection is greater among the supporters of the latter political party. Chinese cars are, in all cases, the second option chosen when considering those who are willing to buy an electric car and those who value it as a possible purchase. The Germans are the ones who obtain the most support and the first option in all cases, with the greatest support among Green voters and with the AfD as the party with the greatest reluctance to buy it.

Since we were children we have been told that Jupiter is enormous, colossal, exaggeratedly large. Turns out not so much.

by

There are things that we learn in childhood that accompany us throughout our lives and one of them is to recite the Solar System at once, which has its disadvantages: for those of us who are already old, mentioning Pluto (which It is no longer a planet) either make mistakes when estimating distances interplanetary. Another classic misconception is the size of Jupiter. Data from the Juno mission published in Nature Astronomy They change the shape and size of the colossus of the Solar System. Jupiter is flatter and smaller than we thought. We knew that Jupiter was the largest planet in the Solar System, a gaseous colossus whose mass exceeded that of the rest of the planets combined, which gave it the power to be almost the conductor of the orchestra (with the permission of the Sun) as long as its gravity had a lot of weight. Its large magnetic shield protects its moons from solar radiation, it has iconic clouds and storms in astronomy and its Great Red Spot It exceeds the Earth in size. But there is something wrong with its shape and size. The Context. The missions Voyager and Pioneerdating back to the 1970s, established figures that today we read in science books: that Jupiter has an equatorial radius of 71,492 kilometers and a polar radius of 66,854 kilometers. With this model, the planet was assimilated as a sphere flattened at the poles (oblate spheroid). These dimensions were calculated with just six indirect measurements with profiles of radio occultation. The discovery. Because what Juno has seen shows that the equatorial radius is approximately 8 kilometers smaller and the polar radius is about 24 kilometers smaller than previous missions said. Qualitatively, Jupiter is flatter. The first thing that comes to mind is: How important are eight kilometers on a planet 140,000 kilometers wide? Well scientifically, it has it. In fact, it’s the difference between whether the laws of physics fit or not. Why is it important. Well, because although the difference is comparatively minor, the fact that it is smaller and has a flatter shape has thermodynamic implications. Thus, it suggests a colder atmosphere enriched with heavy elements that better suit what the Galileo probe measured in 1995. Additionally, having accurate geometry is essential to understanding what’s inside and interpreting the gravity data provided by Juno, so we can accurately map how its mass is distributed inside and how hydrogen behaves under extreme pressures. On the other hand, knowing Jupiter better is getting closer to the recipe of how the Earth was formed and going beyond: facilitating the understanding of thousands of other exoplanets giants that we are discovering in the stars. Radio occultation operation diagram. MPRennie Wikipedia Juno’s look. Both Pioneer and Voyager and Juno use radio occultation, that is, they use the same physical principle. The radio occultation technique consists of measuring how a planet’s atmosphere bends and slows down the radio signals of a probe when it is hidden behind it. By analyzing the delay and deviation of these waves from the Earth, the scientific team can precisely calculate the density and pressure and therefore the exact shape of the planet. Of course, from a technological point of view there has been half a century of evolution and it is noticeable in terms of quality due to its multiband operation, precision and repetition. Thus, the probes of the 70s mainly used one radio band while Juno uses two, which allows, among other things, to eliminate noise. Likewise, the original ones were passing missions in front of the planned June orbit, that is, we have gone from having six points to an almost complete map. And finally, ground-based tracking systems are night and day when it comes to measuring changes in frequency and signal arrival time.

China decided to privatize its daycare centers in the 1980s. Unknowingly, it was creating its enormous birth crisis.

by

Not long ago, China had an excess birth problem. For more than three decades, the one child policy stopped the rapid growth of the population, but now its problem is just the opposite. The demographic crisis has turned around and Chinese population is plummeting. The government has launched plans to encourage births and its latest idea is to improve critical infrastructure. Target: daycare centers. They tell it in South China Morning PostChina is reviewing what will be the first law regulating the child care services sector. The measures will focus on children under three years of age, with the aim of building a society “fertility-friendly”. Among its key measures are improving the quality of the service, ensuring that professionals have the necessary qualifications for the position and expanding the offer of more affordable childcare, which will reduce the cost of parenting. Who takes care of the children. China is encouraging couples to have children through different measures and daycare centers were one of the key aspects to improve. Since the 80s, The state stopped offering public daycares, shifting the burden of care to families. Society adapted in the most predictable way: that the grandparents were the ones to take care of the children (something that it doesn’t always turn out well) or that the woman reduced her hours to take care of the care. A question of money. The lack of regulation has caused the supply of affordable daycare centers to be scarce and with insufficiently qualified professionals. Quality daycare was a luxury available to a few, while for less well-off families it is a last resort. The new law seeks to promote the creation of new state centers at more affordable prices. and trust. The scandals over cases of abuse in Chinese daycares are well known inside and outside their borders, and have also been given cases of abuse by babysitters. If, in addition to the fact that it is an expensive service, we add the problem of lack of trust, it is not surprising that care in the early years ends up being a deterrent factor for many families. In 2021, only 5.5% of Chinese children under three years old were in daycarea figure that contrasts with the 88% of schooling from 3 to 6 years old. Other measures. Since the end of the one-child policy in 2015, the government has implemented several plans to correct the declining birth rate curve. Along with births, marriages also declined, so it was proposed teach marriage and love classes and even be a kind of matchmaker for help young people find a partner. His last measure is one of the most striking: put a special tax on condoms.

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.

Will Smith’s last concert has resulted in enormous public success. Public made with ia

by

Will Smith has been harshly criticized for publishing A promotional video of your tour in which the public, instead of being real, seems to have been generated or altered by artificial intelligence, showing details that are usually common in videos of this type. It is not the last controversy linked to AI, which seems to be impacting unexpected ways in the music industry. What Smith is, in fact, only one more than a gigantic phenomenon that is changing entertainment. False people. The video, shared on the official social networks of Will Smith (and that at the moment remains without withdrawing), promotes his tour ‘Based on a True Story’ and shows fans absolutely delivered in his performances. The visual anomalies were quickly detected by the commentators of the video: with blurred faces to the classic hands of six fingers, alien expressions or mutations of horror film. It is undoubtedly a curious decision at this point in Will Smith’s career, which delves into the authentic Public Relations Nightmare that the star is living. 27 Spotify tricks – Control your whole music like nobody! Since 2022 in free fall. Will Smith has been in an authentic image crisis that started when He glued a slap to chick rock at the Oscar ceremony. Since then, and despite some blockbuster such as ‘Bad Boys: Ride or Die’, his career is a real succession of ups and downs. After a decade without publishing music has edited an album that has gone unnoticed, despite his clear attempt that nostalgia for times where his image was impoluta plays in his favor. Such controversial decisions (and on the other hand, easily avoidable) as it prevents him from recovering control of the narrative of his career. The AI ​​in front of the music industry. A few weeks ago we talked about how, while real groups were from Spotify To show their disagreement with the investments of the CEO of the platform, they began to emerge false groups created by artificial intelligence. It is, again, a relevant detail in a sector of the entertainment industry that is increasingly influenced by the overwhelming presence of the IAS: It is estimated That by 2028, the music generated by AI could represent up to 60% of the income of the musical sector and 20% of the total reproductions on streaming platforms. AI in the composition. More and more, the tools managed by AI are part of the creative processes: Boomy and Jukebox allow to create music from text descriptions, but the processes are not exempt from controversy. In a recent interview, the young American rapper Babychiet recognized that composing chatgpt: introduce some initial clues on the platform about the song theme and then ask the AI ​​to develop from there. The controversy between those who defend that this process removes the human component to the songs and those who defend it as a legitimate tool is served. More false groups, more false albums. The group generated by AI that we commented above was The Velvet Slown, a folk band whose image and music was entirely created artificially, and adds millions of views. But this situation is acquiring new nuances: the British folk singer Emily Portman discovered in her official Spotify, Apple Music and other platforms profile A false album called ‘orca‘Composed of ten songs generated by artificial intelligence and that imitated his voice and musical style in a completely reliable way. Spotify has taken three weeks to eliminate the album from its profile, with the consequent criticism of real artists to the platform. It is another use of AI, not quite legitimate, to which we can get used to. Will Smith’s false public is easily identifiable, but … and when is it not? In Xataka | The problem is no longer that Spotify has been filled with artists AI: is that AI is “reviving” dead musicians

the enormous shell of the dome has been completed

by

He Canary Islands Great Telescope It is, today, the largest optical and infrared telescope in the world. However, if everything goes according to plan, that position will go to the Extremely Large Telescope (ELT) in 2028. The project, under the orbit of the European Southern Observatory (ESO), is being developed on Cerro Armazones, in the Atacama Desert, in Chile. Photographs taken earlier this year show the progress of the works. The framework of the enormous dome, with a diameter of 93 meters, has been completed, so the tasks now focus on the assembly of the outer cover of aluminum plates. This cover will act as a “shell” that will protect the equipment from the adverse climate of the location. Construction of the world’s next largest telescope advances The main protagonist of the material shared by ESO is high altitude metal structurewhich will be responsible for supporting optics and instruments during astronomical observations. This 50-meter-high piece will contain the five mirrors of the ELT and will have to be moved so that the telescope can point to different parts of the sky. To talk about ELT is to refer to several milestones. The primary mirror of 39 meters in diameter will be made up of 798 individual hexagonal segmentsand it will be the largest ever built. The secondary mirror will reflect the light from the primary mirror onto the tertiary mirror. The three mirrors should offer better observations over a wide field of view. Image: ESO/G. Vecchia | ELT under construction in January 2025 But there is more. The fourth mirror is very interesting because it is an “adaptive” mirror. It has been designed to deform to correct atmospheric turbulence and vibration of the telescope structure and its movement. Thousands of actuators intervene to give life to this feature that will deliver sharper images. Image: ESO/G. Vecchia | ELT under construction in January 2025 The fifth mirror is the smallest, but not the least important. It is a very light and rigid optical piece that moves with great precision to ensure that the images arrive stabilized to telescope instrumentsthat is, its multiple spectrographs and cameras that will receive the light to analyze it in detail. Image: ESO/G. Vecchia | ELT under construction in January 2025 It’s been a long time since this project took its first steps. The preliminary design of the telescope was published in 2006 and in 2010 Cerro Armazones was selected as the ideal place for its construction. The reason was very simple: it is a place whose climatic conditions greatly favor the observation of the cosmos. Image: ESO | ELT render The hill is far enough from cities to suffer considerable light pollution. There is also a small percentage of precipitable water vapor. Have you ever wondered why stars blink when we look at them? It is due to the conditions of our atmosphere, such as density, temperature and wind. The signing of the agreement between Chile and the ESO came in 2011, which included the donation of an area of ​​189 square kilometers for the installation of the telescope and the concession for 50 years of the surrounding area. Construction began in March 2014. The project has a budget of 1.45 billion euros and, as we say, it should be operational in 2026. The ELT promises to capture 15 times more light than the Gran Telescopio Canarias and offer sharper views than the Hubble Space Telescope, observatory aiming to retire soon. As we have noted, the ELT will have a 39-meter diameter mirror, key to achieving its objective: obtain direct images of exoplanetsanalyze their atmospheres and measure the expansion of the universe.

Trump has made it very clear that he wants to conquer Mars. Now NASA has the enormous problem of not being called SpaceX

by

Trump made just one space promise during his inauguration speech, but it was no small feat. The Martian dream. Between cheers and jumps of enthusiasm of Elon Musk, Donald Trump pointed out Mars as new “manifest destiny” of the United States. The newly inaugurated president promised to take astronauts to the Red Planet and plant the American flag in Martian soil. Trump stated: “We will pursue our manifest destiny to the stars, launching American astronauts to plant the flag on the planet Mars.” His words are not coincidental and have a clear influence, but they seem to mark a change of priorities for NASA that leaves the future of the Artemis lunar program. The influence of Elon Musk. “We’re going straight to Mars, the Moon is a distraction,” wrote the CEO of SpaceX two weeks ago. No one quite understood the scope of that tweet, since SpaceX has a very important contract with NASA to build the lander for the Artemis III and IV lunar missions, but now that message resonates on Capitol Hill. There, President Trump focused on Mars. It could just be a rhetorical statement (slowly, but surely, we have to get to Mars before China does), but with Elon Musk as a key ally, the new government could really be preparing a radical shift in astronautics strategy. The current Artemis program. It was precisely Trump’s first term that shaped NASA’s current lunar program. The then administrator, Jim Bridenstine, managed to put the United States’ return to the Moon on track with an architecture that combined NASA’s internal developments (the SLS rocket and the Orion spacecraft) with commercial spacecraft from private companies (SpaceX’s Starship HLS and the lunar module Blue Moon by Blue Origin). In turn, Bridenstine promoted a series of unmanned lunar missions and the creation of the Artemis Accordswhich already has 53 signatory countries, for international cooperation in future missions to the Moon, including the construction of a lunar base, the commercial exploitation of the satellite and everything that comes after (Mars, comets and asteroids). The Moon is a cruel lover. Artemis is not at her best. Manned missions have been delayed for problems on the Orion ship and delays in Starship development. Furthermore, the insane cost overruns of the SLS rocket have put a good part of public opinion against the current architecture of the program, which could be reconfigured with the support of SpaceX’s new Starship and Blue Origin’s New Glenn rockets. To make matters worse, the first two commercial missions associated with Artemis (CLPS‑1 and CLPS‑2) failed to reach the Moon or lie down when landing on the moonwhich has precipitated the cancellation of other more important missions such as NASA’s VIPER rover. But until Trump’s speech, there was nothing to predict that the Artemis program would be in danger. Is it really? From the Moon to Mars. Until now, NASA’s plan was to establish itself on the Moon throughout this decade and the next (or at least in the Gateway lunar station in orbit with the satellite) to prepare for the jump to Mars in the 2040s. Prioritize the Red Planet I would leave three scenarios to the foreseeable new administrator from NASA, Jared Isaacman: A reduced lunar program, without aspirations to create a large lunar base like the one proposed by the ILRS program led by China. Thus, the United States would continue in the race to put the first woman on the moon without stopping to focus on Mars. In exchange, he would cede lunar land to his opponents A bifurcated program with parallel lunar and Martian missions that do not throw away everything that has been developed so far. It would be the logical step if NASA’s budget were unlimited, but with the huge investment what the lunar program entails, adding a Martian program seems impossible A total redirection to the conquest of Mars. Following Elon Musk’s vision: the Moon is a distraction from the ultimate goal of become a multiplanetary civilization. Even with a majority in Congress, it is the option in which giants such as Boeing, Lockheed Martin, Northrop Grumman, and even New Space lose (Blue Origin has several lunar contracts). It seems complicated for congressmen to agree on a clean slate, but it is not totally impossible How would the United States get to Mars? There would be a public tender, but one option immediately comes to mind. NASA could adopt the SpaceX Mars program as your own. Elon Musk said SpaceX planned to launch five uncrewed Starships to Mars in 2026 and, if they managed to land, the first crewed mission to Mars in history in 2028. The experts agree at a crucial point: a mission with astronauts to Mars in the next four years is technically impossible if it is to be done with guarantees, since the scientific and technological challenges are monumental. But there were also many people convinced that Trump would not win the election again while Musk bet money that yes I would.
