Exorbiting the International Space Station in two years

by

The International Space Station is, as the name implies, an international project. One of the most important and monumental international projects in history, the result of the collaboration of multiple countries. Now an entrepreneur wants to accelerate his end. In an ideal world, entrepreneurs could not undo what several countries have built. Much less if the reason is accelerate the conquest of Marsfor which the new rocket of said entrepreneur will be needed. But this is not any businessman. He is the richest in the world and has enough political power and influence to take us seriously. Elon Musk’s last idea. “It’s time to start preparations for exorbiting the international space station,” Elon Musk wrote in his X profile during Thursday afternoon. “It has fulfilled its purpose. Its incremental utility is very small. Let’s go to Mars.” When exactly? “The decision depends on the president, but my recommendation is to be done as soon as possible,” The businessman said. “I recommend doing it in two years.” That is, in 2027, two years before the date agreed by the ISS partners. An accelerated ending. At 25, the International Space Station shows signs of aging. Investments in maintenance have been increasing. Structural fatigue begins to be a concern. The risk of impact with space garbage does not stop growing. The plan agreed by the ISS partners was to keep the operating station until 2030 and then tow it with a special ship to a safe place (presumably the Pacific Ocean) for its atmospheric reentry. NASA asked Spacex to develop this vehicle by 2030. By then, hopefully, there will be Commercial Space Stations In the low terrestrial orbit. But by 2027, the year proposed by Musk, the continuous presence of Americans in space would probably be interrupted. The space would continue inhabited, yes, By Chinese astronauts. Can Trump retire the ISS a long time? That is the big question. The International Space Station involves five space agencies: NASA (United States), Roscosmos (Russia), the European Space Agency (Europe), Jaxa (Japan) and CSA (Canada). Canada operates the Canadarm robotic arm, Europe the robotic arm was and the Columbus laboratory … but in broad strokes, the ISS consists of two main segments that are from the United States and Russia. In the same way that Russia was threatening to decoup down her and leave before 2030, Donald Trump could propose the same. It is hard to imagine a scenario in which the European, Japanese and Canadian partners of NASA agreed with this abrupt ending. What would happen, for example, with European astronauts who were going to fly to ISS before 2030, Like the Spanish Pablo Álvarez? But it is not impossible to occur. “You are delayed.” Musk’s statements, yes, could have been hot written. He published them just a few hours after exploding against the former commander of the International Space Station Andreas Mogensenwho had called him a liar for statements in Fox News. Musk and Trump have been circulating the narrative that Astronauts Butch Wilmore and Suni Williams were abandoned by former president Biden in space after the Fiasco of the Boeing Starliner ship. Actually, NASA ordered a return plan for both during the Biden administration: to reserve two empty seats on the CREW-9 mission, which will return to Earth at the end of March (an exclusive ship for them would have cost dozens of millions). When Mogensen pointed out this in his X profile, Musk replied: “You are a complete mental retardation. Spacex could have brought them back several months ago. I offered this directly to the Biden administration and refused. His return was delayed for political reasons. Stupid.” Image | Elon Musk, Nasa In Xataka | It is not that Elon Musk has managed to introduce its influence on NASA. Is that he has entered sweeping

Three years after the beginning of the war, Europe wants to enter. The problem is that there is only one prepared nation: Ukraine

by

Europe has decades without a direct armed conflict in its territory, with the exception of Yugoslavia wars in the 90sthe last great episode of violence in European soil. Since then, security in the continent has been marked by A strategy based on deterrence and diplomacymore than in military confrontation. And, suddenly, the conflict in Ukraine recalled that fireworks It is not the same as direct fire. Europe before Ukraine. As we said, the European armed forces have been reserve for a long time. In fact and how we will see, mostly they have been reduced and adapted to a context of stability, with investments limited in defense and a focus on Peace maintenance and humanitarian assistance operationssuch as missions in Balkans, Africa or the Middle East. Despite the growth of NATO and its presence in Eastern Europe, European armies have been more accustomed to acting in controlled scenarios that to prepare a direct confrontation against a weight opponent such as Russia. Fireworks. In fact, this approach has led to many military operations from European countries being Mainly exercises, joint maneuvers and drills in allied countries such as Slovakia, Poland or Latviabut without the real experience of a conventional combat against a military power. And it is not the same to deploy troops for an exercise in the Baltic countries to face in battle against a force like the Russian army. Enter the war. Under all this context we arrive at this week. A few days ago several European leaders have gathered in Paris to discuss the possibility of sending troops to Ukraine as part of A possible peace agreementalthough the viability of this measure depends largely on the support of the United States. In fact, the summit was promoted by the decision of the Trump administration of exclude Europe from negotiations They started in Saudi Arabia between Washington and Moscow, although Trump has suggested that Europeans could perform “a peace maintenance role.” Plans and divisions. And then Europe seems to have realized that the “defense” had it careless. According to The Washington Postsome European countries consider The deployment of up to 30,000 soldiersthat, yes, they would not be on the front line, but as a deterrence in case of a resumption of the conflict. Another option, or plan B, is the one that They have called “resettlement force” destined to protect Ukraine from future Russian attacks in case a peace agreement negotiated by the United States is reached. That said, France is the country with the most advanced plans estimating that could contribute almost 10,000 soldierswhile the United Kingdom, through its prime minister Keir Starmer, has opened The possibility of a British contribution. And so far, because the rest of the countries have shown a more ambiguous position. Sweden and the Netherlands, for example, They do not rule out the shipment of troopsbut they have not made a specific decision. Germany, Poland and Spain have rejected the idea, At least for now. Foreign Minister Olaf Scholz emphasized that Any solution should be based on a strong Ukrainian forcewhile Donald Tusk, Prime Minister of Poland, said that Warsaw “does not contemplate sending Poles soldiers to Ukraine.” For its part, the Spanish government was blunt when pointing out that Peace is still far and only depends on Putinmaking it clear that any military mission should define objective, participants, mandate and leadership. Strategic objectives. If the “plan B” is given, with a peace agreement underway, the main mission of this eventual “resettlement force” would be guarantee the safety of Ukrainian airspaceallowing the reopening of commercial flights, and protect maritime trade in the Black Sea, fundamental for grain exports and other essential goods for the Ukrainian economy. It would also be prioritized The protection of key infrastructure such as Public Plant and Public Servicesthat have been constant target of Russian bombing since the beginning of the war. Ukraine proposes a broader approach. Meanwhile, Ukrainian President Volodimir Zelensky stated that Ukraine’s security does not necessarily require foreign troops in his territory. Proposed The creation of “Armed Forces of Europe”capable of responding on land, sea, air and artificial intelligence before any Russian aggression. He also stressed that advanced air defense systems would be effective measures to strengthen security without requiring permanent foreign troops. The elephant in the room. No doubt, Europe’s plan faces important diplomatic obstacles, the first of all: United States support It is, at the moment, uncertain. Although the Trump administration has insisted that European troops must guarantee the security of a future peace agreement, Defense Secretary Pete Hegseth made it clear that They must be part of a mission not related to NATO and not be protected by article 5 of mutual defense. Not just that. Even in the uncertain scenario of a peace agreement, the mission and role of Europe would require an American “backstop”that is, a support from the United States in case of a military escalation. Although there are no specific details, this support is expected It focuses on aerial power with operations based on Poland and Romania. In this regard, Starmer and Macron will travel to Washington next week To press Trump and ensure that the United States provides this strategic support. “Old” defenses. In the background, what is showing is a great weakness in its defenses, possibly oxidized. In fact, the Prime Minister of Denmark, Mette Frederiksen, warned this week at the Munich Security Conference that Ukraine is making weapons faster and less cost than any other country in Europe. It is not a trivial detail. It does so despite being at war, which shows the slowness of the continent in strengthening its military capacity. Frederiksen urged to reduce bureaucracy and increase arms production in collaboration with the United States emphasizing that Europe can no longer act as if it were in peacetime. The rise of the Ukrainian military industry. From the Russian invasion in 2022, Ukraine has exponentially increased its armament productionmanufacturing missiles, obuses and large -scale drones. In 2024, 30% of the military equipment used … Read more

For five years we have tried to decipher a television signal that came from the sky. The mystery has been resolved

by

The news for the year in the cosmos has a name and surname: 2024 YR4, that asteroid whose probabilities of impact on Earth do nothing but up. But thousands of kilometers from our planet continue to happen fascinating events. Without going very far, X -ray telescopes have just revealed A superstructure of more than one billion light years. There are more, because for five years astronomers had been looking for a response to a television signal that came from space. The enigma has just been resolved. The mystery of the signals. For five years, astronomers who analyzed the data of the Murchison Widefield Array radio in Western Australia found an unexpected enigma: A television signal from heaven. Since the telescope is located in A radioelectric silence zone Designated to avoid human interference in radioastronomy, the detection of said signal was particularly disconcerting for the community. Even more strange was the fact that the signal It seemed to move through the skywhich led to all kinds of speculation about possible reflections of our own transmissions until, of course, theories about extraterrestrial activity. The answer, as almost always, It was something simpler. The discovery: airplanes. Apparently, the turning point came when Jonathan Poly, physicist at Brown University and leader of the United States research team, He had a revelation: “We said: ‘I bet the signal is being reflected in a plane’”. While this hypothesis had already raised before, no one had confirmed it with certainty. To check it, the equipment used advanced signal processing techniques, as close field corrections and beam formationwith which they managed to better focus close sources of interference. What happened? That the analysis revealed that The reflected signal corresponded to the Channel 7 frequency bandan Australian digital television station. Perhaps more important than that, the calculations on the altitude and speed of the reflective object indicated that It was a plane in full phase of cruiseflying at 11.7 kilometers of altitude at a speed of 792 km/h, data that coincide with the usual characteristics of a commercial flight. A problem for astronomy. As indicated in your recently published studythis type of interference represents a serious problem for astronomers, since Contamin the data and can force the elimination of large amounts of valuable information. According to Jade Chucharmefrom Brown University, “It’s like trying to listen to a friend whispering on the other side of the table while a child screams in your ear.” In this way, every time a television signal is reflected in a plane, It overlaps cosmic waves That astronomers seek to analyze, which can make large sets of observations must be ruled out. Not just that. As they underline, the team’s discovery is key to Develop interference elimination methodswhich will allow filtering these reflexes without losing important astronomical information. However, the problem is not limited to airplanes: satellites in orbit represent an even greater threat. Are we too loud on earth for astronomy? It is the big question that slides from the finding. The number of satellites in orbit It is still increasingwhich aggravates the problem of radio interference. Although scientists are improving data filtering techniques, some begin to question whether planet Earth himself remains adequate place for radioastronomy. According to poor“If we cannot find a silent sky on earth, maybe the earth is no longer the indicated place.” Be that as it may, some astronomers have begun to consider The possibility of moving radioastronomy to spacewith projects that propose the installation of telescopes in the hidden face of the moon, where the terrestrial interference would be minimal. In that sense, the discovery of Poly and his team not only solves a five -year mystery, but also marks a crucial step for the preservation of radioastronomy in an era where electromagnetic pollution is a growing problem. With the advancement of technology, the struggle between the exploration of the cosmos and the signs generated by the human being could define the future of astronomy. Unfortunately for believers, no one was watching TV in space.

Apple has been making the bulk of the iPhone in China for years. Now wants to leave … and China prevent it

by

Apple is accelerating its diversification plan for the production of the iPhone outside of China … with India as the main alternative destination. Is A story that comes from afar But now steal the accelerator. As revealed Financial Times In an extensive profile about this movement, Apple is running this movement with extreme caution so as not to antagonize Beijing, who sees with suspicion how he could lose his dominant position in the global supply chain. Why is it important. This manufacturing migration can end up being one of the biggest changes in the world economy in decades. China has been the factory in the world for two decades and Apple’s main industrial partner, but the cook company needs to minimize its risks to an increasingly tense and complex geopolitics. In addition to China, it no longer has such a cheap labor that it had a decade ago: its salaries have grown to the beat of its economy. In Xataka More and more Apple suppliers move from China to Vietnam. The problem is that there are not enough workers In figures: The Indian production of the iPhone already represents 15% of the global total. It is expected to reach 25% in 2027. Only the Chinese province of Henan exports between 50 and 60 million smartphones A year, equivalent to all the annual demand of the iPhone in its largest market, United States. The backdrop. This Apple strategy, known as “China Plus One“, the reasons began to take shape: Commercial tensions with the US during Trump’s first legislature. Logistics problems during pandemia, which They cost Apple 8,000 million in income. Chinese restrictions on the use of Apple devices by its officials. The new tariff threats after the start of Trump’s second legislature. Between the lines. Beijing is actively hindering this exodus hindering the movement of Chinese technicians towards India. It is also restricting the export of critical equipment, blocking the entry of Chinese manufacturers in India and imposing regulatory obstacles to Apple services as Apple Intelligence. India, meanwhile, is taking advantage of the opportunity: Has allocated 6,000 million dollars To encourage smartphones production. Tata, the largest Indian conglomerate, is positioning itself as Apple key partner. Tamil Nadu and Karnataka They compete for attracting investments. The iPhone 16 They are already manufactured in India. For the country it is a great milestone. In summary. Apple needs to balance this transition very delicately. China remains vital for its supply chain, but a company like Apple cannot afford to depend on a single country in an increasingly volatile geopolitical context.

The “hypercarnivore” that lived 30 million years ago and today focuses the attention of paleontologists

by

The Egyptian paleontologist Shorouq al-Ashqar and her team were about to conclude their work in the archaeological site where they worked when they noticed something that caught their attention. As explained by Al-Ashqar, it was teeth of considerable size that stood out from the rock. Bastetodon Syrtos. The teeth belonged to the fossilized skull of a mammal of about 30 million years old and belonging to a species so far unknown. The team responsible for the finding has cataloged the new species He has given him a name: Bastetodon Syrtos. The “almost complete” skull found has allowed the team to obtain valuable information about This new species. For example, let’s heal the animal would have had a size similar to that of modern leopards. B. Syrtos would have belonged to the order of the hyitodontes (Hyaenodonta), an already extinct group of mammals related to that of carnivores (Carnivora), The group in which there are species present such as cats and hyenas. The name Hyaenodonta It makes reference to these animals since, despite not having a direct relationship, the shape of the teeth of the extinct order is similar to that of the teeth of the modern species. Hypercarnivorous diet. The skull It has even served to get an idea of ​​what this animal ate. The team indicates that B. SyrtosIt would have been what we know as a “hypercarnivore” (this time in a non-taxonomic but strictly food sense), an animal whose diet would have consisted of at least 70% of meat. This species would have been, their discoverers believe, on the cusp of the “food pyramid” in its ecosystem. The team presented its finding Through an article In the magazine Journal of Vertebrate Paleontology. Etymology of a name. The choice of name is a wink in the history of the country in which it has been discovered. The Egyptian goddess Bastet embodied, Explain the teamprotection, pleasure and good health. Bastet was represented well as a cat well as an anthropomorphic figure with a feline head, similar to that that members of the newly discovered species could have had. “-Oode,” on the other hand, it is a usual suffix in zoology that means “tooth.” The fayum. Thanks to its oasis, the fayum is one of the few areas where the water dyes green the land beyond the Nile Valley, which makes it a key region for agriculture in Egypt. But there is another characteristic that makes this environment interesting: its deposits, both archaeological and paleontolocic. The new finding, in fact, has served to give context to some remains found in the region 120 years ago. From the skull found and fossils discovered in 1904 in the region belonging to hyitodars of a size even larger than that of B. Syrtos. They classify these remains into a different genre to what they have called Sekhmetops. Bastetodon and Sekhmetops. Until now these animals (whose new name also refers to an Egyptian god, Sekhmet) had been classified in the same group as European hyenodontes. The new classification places the origin of the two new genres, Bastetodonand Sekhmetopsin the African continent itself. According to the new study, these two genres would have expanded in successive waves from Africa to the adjacent continents and even to North America.

A superstructure of more than one billion light years

by

Almost a third of all the galaxies that we can observe in the universe are grouped into five structures of an unimaginable scale. Astronomers have just discovered the greatest of all. With more than one billion light years in diameter, Quipu is the largest supplies ever discovered. A super -as -called Quipu. Quipu is A galactic supercumulus of 1.3 billion light years (more than 400 megapatscs) with an estimated mass of 2 × 10¹⁷ solar masses, about 200 four times more massive than the sun. The pantagruélica structure has been baptized as quipu in honor of the strings and knots system of the Incas. The Inca wove wool threads making knots in different ways to count or transcribe messages, such as those that scientists begin to decipher in the filaments and ramifications of these cosmic superstructures. The cosmic network of matter. Our galaxy, the Milky Way, is part of the local group along with its neighbor Andromeda, the triangle galaxy and numerous satellite galaxies. The local group, in turn, is part of a large collection of clusters called the Galactic Super Cumulus of Virgo. At the same time, Virgo’s supercumulus is within a gigantic filamentous structure called Laniakea. Laniakea contains approximately 100,000 galaxies and extends over 520 million light years. Thus, as the scale increases, the matter of the universe is weaving a cosmic network that astronomers are trying to capture on a map. Five superstructures. An international astronomer team located in Germany, South Africa and Spain has made The first study at a global scale of the biggest structures of the universe. Using galaxies clusters observed in X -rays By the Classix Cluster Survey, the researchers identified five especially prominent superstructures. In addition to Quipu, they found Shaley, Serpens-Corona Borealis, Hercules and Sculptor-Pasus. These five superstructures group approximately 30% of the galaxies and 25% of the matter of the universe, occupying 13% of the total volume. Its small lateral ramifications visually evoke the knots of a quipu, which somehow encode crucial information on the formation and evolution of the cosmos. Quipu’s influence. Immense concentrations of mass such as Quipu are fundamental to understand how the network of matter is weaved in the cosmos and why there are discrepancies between the Hubble constant, which measures the expansion of the universe, and the speed at which the galaxies are separated. Quipu’s enormous mass exerts a significant impact. Its severity is so great that it can be inducing peculiar movements in the galaxies, as well as distortions in the microwave background radiation, a very weak electromagnetic echo from the Big Bang.

The extreme cold has not touched Spain for two years and experts fear that we are about to see a third. With all that implies

by

Spring is just around the corner and, we like it or not, this means that we can start drawing conclusions. The first is that every minute that passes is more likely to finish winter without seeing any “cold wave.” And that is not even what most worries meteorologists. Because the real problem is that it would be the second consecutive winter without cold waves and a third would be at hand. With all that this entails. Isn’t it a bit precipitated to give the winter for dead? The truth is not. Although this week an extremely cold mass of air will cover a good part of Europe, Spain will escape from it. And on March 1 (which is when climate spring begins) is very close to be able to house realistic hopes about an extreme cold episode. And, in the background, what we are going to see this week summarizes very well what has been going on two winters: we have not suffered powerful cold irruptions. They have all stayed north. It is a story that is repeated again and again. But it’s not so weird either, right? That is true. The cold episodes become more and more rare in Spain. In fact, this January can only be described as very warm (Although we have suffered a handful of cold nights). A example that Roberto Granda puts It is that of Molina de Aragón. The average minimum between 1991 and 2020 is -3.3º, but this year it has been at -0.3. The data speak for themselves. In the end, As I pointed out A few years ago our partner Javier Pastor, “is not that it is very cold now, it is that we do not do it because it is no longer so common.” With this in mind, the question begins to be … how long can this last? “Unusual and worrying.” That is, what would happen if the winter of 2026 is still on the same line? The answer, According to Samuel Biener de Meteoredit is summarized in those two words: “Unusual and worrying.” Because we have documented other consecutive warm winters (those of 97 and 98, those of 2000 and 2001 or those of 2023 and 14); But we have not seen three consecutive yet. And we know it will arrive. Because, As Biener points outwarm winters are being increasingly frequent. It is a matter of time that we fit three. And what is the problem? More than a problem (that too), we talk about a fear: that warm winters stop being an anomaly and become the norm. That change is a large-scale disruption of the country’s socio-ecological system. It is no accident that, a few months after the drought, The data begin to be so bad. Again. Not only climatic pressures They hit us stronger than everthe thing is They don’t let us replenish. And that will lead us to the edge of the precipice again and again. Yes it’s true. The current climate is full of paradoxes: Historical ice minimums live with snow maximumstudies on The weakening of the Gulf current They coexist with others that point to nothing has changed in substantial terms and thus a long etcetera. However, there is something that Yes we know is that we are vulnerable And if we don’t prepare ourselves, Let’s be much more.

15 years ago, a forest engineer decided to grow sponges in Galicia. The war against plastic has ended up giving him right

by

In the mid -90s, Juan Carlos Mascato finished studying forest sciences in Hamburg and enrolled in a company in the area. He was lucky: of all the things that company could have needed, he needed someone to speak Spanish, someone to send to Paraguay. It was then that he met the Lugfa and began his crusade against the plastic. Today is the largest producer in Europe in the sponges and natural scourers. And all from a small town in Pontevedra. What is the LUFFA? The LUFFAS are a genus of plants slightly related to pumpkins, cucumbers and melons. In fact, in Southeast Asia is a Very popular food as long as they are collected soon. Otherwise it becomes too fibrous to be consumed. So fibrous that, duly processed, they can be used as exfoliating sponges. For centuries, this type of vegetables (or some of its variants) were widely used and were among the crops of any orchard that would be precious. But the irruption of plastic from the 40s sent them to the drawer of history. Until now what THE WAR OF THE PLASTICS They have returned them to the first line. And what does the European Luffa giant do in Caldas de Reis? It is an excellent question. As Silvia Rodríguez explained in the countrythe clearest reason is that the Mascato family (of German mother, but Father Gallego) had a farm available in a town with a very particular climate that made it a good candidate to try subtropical crops: Caldas. Chance does not end there, of course. Because the processing of the LUFFA includes a fermentation phase in which the hot springs of the Gallego municipality fit as a ring to the finger. No one is a prophet in their land … And in this case it doesn’t happen either. Because the truth is that Iberian vegetable sponges It is little known here in the country. Of the 200,000 sponges that manufacture a year, only 10% stay in Spain. The rest goes to countries such as Korea, Taiwan, New Zealand, Sweden, Finland, Norwegian or East next … Right now, the company works on an online marketing project in Germany and expanding its productive infrastructure to the US. What sponges can teach us. Because although the story is already very interesting, there is something that really crucial: that for decades we have despised many traditional solutions simply because they were. And that is a mistake. This was made clear in 2015 Karolinska Institute of Stockholm when granted your youyou The Nobel Prize in Medicine. Many interpreted him as a prize for traditional Chinese medicine, but it was not accurate: your feat was incredible. Since 1965, your youyou It was analyzing thoroughly Each and every one of the remedies that the millenary Chinese civilization had been selecting. And, indeed, most pure superstition, pseudoscience and placebo. However, he found the Artemisininea revolutionary treatment against malaria. Rethink the past. This is an example of the book that if we approach us with an open (but rigorous) look at the technological history of humanity, we can find really creative solutions to the problems of our day to day. In the middle of a world invaded by plastics, natural sponges are an excellent example.

We have dedicated six years to process images of a black hole to reach a conclusion: Einstein was right

by

Several years have passed since the Telescope of the Event Horizon (EHT) published the famous first image of a black holetaken in 2017. The photo has yes doquestioned by some researchersbut the EHT last year published a second image of the black hole M87*, taken in 2018. The new photo not only validated the original, but once again corroborates the Einstein’s general relativity theory. The largest radio telescope. To obtain the image of the black hole in the center of the Messier 87 galaxy, we needed to build a radio telescope about 10,000 kilometers in diameter. Since the land has a diameter of 13,000, the EHT took a more reasonable path: Extract data from different receptors, telescopes and radio antennas from all over the world and combine them by interferometry. The EHT produced 250 Petabytes of information in a one -week interval. It took a couple of years to process all the information and publish an image. But first, he added a new telescope to the project (the GLT of Greenland) and took the second image of M87* that saw the light in 2024. Six years processing. The second image of the black hole M87*, taken a year and ten days after the original, in April 2018, took six to process and publish, but it was worth it. On the one hand, proves that 2017’s observations were fine. The Persistence of the size of the central shadow In both images confirms the original estimate of the dimensions of the black hole, dissipating the criticisms about the simulations dependence to calculate this data. On the other, comparing the two images shows that the ring of matter around the black hole is rotating as expected. The brightest part has moved 30 degrees, which is consistent with the models of the hole. We are seeing what Einstein predicted. Located 55 million light years from us, M87* is a supermassive black hole in the center of an elliptical galaxy that manipulates the subject with its magnetic fields and expels the one that does not consume at speeds close to that of light. The image of 2018, like its predecessor of 2017, reflects this tumultuous activity with a bright ring around it. This validates the theory that the diameter of the event horizon, and therefore that of the black hole itself, is intrinsically linked to its mass, framing a central shadow that Albert Einstein’s equations predicted more than a century ago. Why it looks like a donut. That brilliant donut called accretion disc should be very fine, but we get very dispersed and unemployed. Throughout the trip he has made through space, his light has dispersed by the dust in interstellar space, which leads us to see it in this way. Despite the dispersion, the image is clear enough to confirm not only Black hole rotation but also the alignment of its rotational axis with a powerful stream of material (“relativistic jet”) that moves away from M87. The importance of reproducing results. Although it will take six years to arrive, this vindic confirmation the findings of the EHT and is seen as a milestone for global scientific collaboration, in addition to a robust confirmation that we are facing the shadow of a black hole and the matter that orbit it. Future data analysis will help better understand how magnetic fields and plasma flows within the accretion disc interact. In the next decade, we could even have videos of the evolution of M87* in time thanks to the next generation program of the EHT (NGEHT), which promises images of greater resolution and a broader range of frequencies. All thanks to the collaboration of observatories from all over the world. Image | Event horizon telescope In Xataka | A group of astrophysics has knocked down Kerr’s hypothesis.

China has been cutting its technology for years. Xi Jiping has just opened the door for that to change

by

Jack Ma, “The Jeff Bezos de China”, It seemed to go directly to stardom. And what happened is that he crashed when he tried to launch Ant Financial Its alleged Fintech of 150,000 million dollars. Or rather, Xi Jinping, the Chinese president who made clear Who was commanded. Ma finished practically missing in actionbut now it has just appeared in an event with Jinping and other great executives of Chinese technology companies. That this happens is as surprising as it is interesting. XI Jinping Meeting with Technological Capos “in China. As they point out In Bloombergthe Chinese president presided on Monday a meeting in which several entrepreneurs and managers of large Chinese technology companies participated. Among them, of course, the presence of Jack Ma, co -founder of Alibaba – and who left the position of CEO in 2019 – that for the first time in years went to an event of this caliber. The major flat. The event was also attended among Ren Zhengfei (Founder and CEO of Huawei), Wang Chuanfu (Founder and CEO of Byd), Pony Ma (CEO of Tencent), Lei Jun (co -founder and CEO of Xiaomi), Wang Xing (CoFundador and CEO from Meituan) or Wang Xingxing (CEO of Unitree Robotics). Apparently nor Robin Li (CEO of Baidu) Ni Yiming Zhang (CEO of Bytedance) went to that event. During the event, they point out in The New York Times, XI asked these entrepreneurs to have the “ambition to serve the country.” And also the richest. The 2024 Forbes list With the richest people in China, it demonstrates that the technological and automobile sector is especially notable in terms of presence. Thus, if we search that list to the personalities of the technological segment in China we see many examples (with its position in that list in parentheses): Pony Ma (Aliaba) (2) Zhang Yiming (bytedance) (3) Colin Huang (Temu/Shein) (4) Robin Zeng (catl) (5) William ding (netease) (7) Jack Ma (ex-alibaba) (8) Wang Chuanfu (Byd) (9) Lei Jun (Xiaomi) (10) Those fortunes, of course, are far from the great fortunes that dominate the Forbes list globally. Thus, Pony Ma, the second greatest fortune in China, is the fortune 57 of the world. Lei Jun, in the 10th position of ranking in China, is 195 in the global ranking. More love for private companies. The meeting seems to point to a possible change in attitude on the part of the Chinese government, which in recent years has left the great Chinese technology act, but always making it clear who sent.

Since then Chinese technology companies have been much more aligned with the philosophy of Chinese president. Thus, the AI ​​models developed by some of these companies must first receive the approval of the government to be able to deploy and use in the country. More tolerance for private. In recent times Beijing has been softening its restrictive policies against Chinese private companies: Qwen, Alibaba’s model, is demonstrating the increasing relevance of the company in this field, but even Apple is managing to include its Apple Intelligence platform On the iPhone in China thanks to their agreements precisely with Alibaba. Chinese Millanoriocracy. In the US we are seeing how the great technological fortunes are aligned with Trump and yield to their policies or even drive them, as is the case of Elon Musk, the richest man in the world today. Chinese magnates have been aligned with Xi Jinping even longer. The influence of the Chinese government on the march of the country’s companies is even clearer and the AI ​​rise is probably the engine of this “repositioning.” His strategic value is evident, and the Chinese president now seems to want to give more margin of maneuver to private companies that are allowing him to compete in better conditions with his great rival, United States.
