If anyone thinks that gambling is a modern vice, we just found a game of chance that is more than 12,000 years old

We are so used to locating the origins of gambling in the civilizations of the eastern Mediterranean (in the Babylonian temples, on the Roman gaming tables) that it is difficult to imagine another scenario. But a study published this month in the magazine ‘American Antiquity‘ changes everything: the oldest known dice do not come from the Old World, but from the western plains of North America, and are at least 12,000 years old. They date back to nothing less than the Pleistocene. Old dice. With his study, archaeologist Robert J. Madden has shown that Native Americans made and used dice at least 12,000 years ago, during the last centuries of the Ice Age. That makes them the oldest known games of chance, more than 6,000 years ahead of the earliest documented dice in Europe. What was believed? Mainstream history placed the origin of dice in the complex societies of the Near East and Eastern Europe, approximately 5,500 years ago. Madden’s findings they relocate that starting point to another continent and to another completely different type of society: groups of nomadic hunter-gatherers of the western Great Plains of North America. Neither palaces, nor cities, nor written culture: games of chance in Pleistocene camps. What are these dice like? Prehistoric Native American dice do not look like the cubes we know. They are known as binary lots: flat, two-sided pieces, made of bone or wood, designed to be thrown on a surface. The result depended on how many marked faces were left face up; Players counted points with small rods and whoever reached an agreed upon number first won. More like a coin toss than the six possible outcomes on a die, but just as useful for generating random outcomes. Why was there confusion? The problem was classification. When archaeologists found pieces of this type, they simply labeled them as “game pieces.” There was no systematic criterion to identify them as given. madden corrected that way of seeing it developing a morphological test based on a catalog that the ethnographer Stewart Culin published in 1907, ‘Games of the North American Indians’, where he documented 293 historical sets of indigenous dice from more than 130 towns. With that framework applied to the published archaeological record from across the continent, he identified more than 600 additional dice. Where were they? The oldest dice come from three sites in the Folsom culture: Agate Basin (Wyoming), Lindenmeier (Colorado) and Blackwater Draw (New Mexico). It is believed that these pieces They are between 12,800 and 12,200 years old. Lindenmeier, north of Fort Collins, has 14 different artifacts that meet the criteria, leading some archaeologists to speculate that it was a large seasonal congregation site for dispersed groups. The density of material found there points to something more than a temporary camp. What is most striking is the continuity. These objects appear in deposits from all major periods of North American prehistory, without detectable interruption from the late Pleistocene until after European contact. A 12,000-year-old tradition that still works: Madden himself found tutorials on YouTube where native groups explain how to play versions of the same games from two millennia ago. How to play. Possibly, these dice were used in games that we can connect with what we tell about the patollithe Mesoamerican board game of the Mayans and Aztecs: that was also a game of chance with a deep ritual dimension, found in the archaeological works of the Mayan Train. The social and religious function of the game seems to have been constant in very different pre-Columbian cultures. Madden describes these games as “social technologies of integration”: neutral spaces, governed by shared rules, where groups with little or no prior contact could interact, exchange goods and information, and build alliances. The religious dimension is equally documented. Numerous native oral traditions describe dice as a sacred activity: the gods themselves participate, and in some cosmologies the creation of human beings is the result of a cosmic game.

ChatGPT has the same chance of hitting the Lottery Jackpot as a witch reading the guts of a crow

There are those who always play the same number. Others travel half of Spain looking for the combination they have dreamed of or simply a special date. This dance of fetishes related to the Extraordinary Christmas Lottery Draw is now added a new name: ChatGPT. And the question is not only whether artificial intelligence is capable of guessing the winning number, something that is obviously not possible. It goes much further than that: there is a lot of superstition in this, but also of believing at face value what the AI ​​tells us. Even when we know that there is nothing behind it to support its results. ChatGPT and the lottery. Christmas is coming and with it interest in the Lottery increases. And with it, an unexpected protagonist also emerges again: ChatGPT. The OpenAI ‘chatbot’ has become another Christmas classic thanks to the fact that, one more yearwe Spaniards ask you again what the winning number will be. The objective is clear: that ChatGPT deciphers the tenth that the Fat Man will win in the 2025 Christmas Lottery. Although only chance rules here. It doesn’t get wet. The Christmas Draw is carried out using a system of two drums, with a manual mechanism, in which all the balls are identical, both in weight and size, so that they have exactly the same chance of winning. The prize is drawn from the first pot and the number to which it is associated is drawn from the second pot. The procedure for drawing the balls is completely random and, therefore, so is the winning number. The chance of getting it right is 0.001%. If you have ever tried to ask ChatGPT what the Gordo will be on December 22, its answer is what it should be: If you insist, he also repeats the same thing: “I cannot tell you with certainty what the winning number of the Spanish Christmas Lottery will be. And in fact no one can. The draw is designed to be totally random; each number from 00000 to 99999 has the same probability of being awarded.” He is not trying to sell us the bike and makes it very clear why: “although there are those who try to use theories, superstitions or even artificial intelligence to predict numbers, these methods have no real foundation: in the end, each number still has exactly 1 in 100,000 probabilities.” Finish singing. But, if we try to scratch a little more, it ends up showing a random number. If you give it a ‘prompt’ asking for a number based on a mathematical sample or taking into account the history of winning combinations, ChatGPT tells us that “I can give you a simulated number as a result of a fictitious statistical sample, but you must be clear that it does not increase your probabilities nor does it represent a real prediction.” And then, what was expected, his bet. In this case, 32,704. Of course, by trying to ask the same question in several different conversations, each time it offers a different answer. The ending doesn’t even have to match. It’s a totally random answer again. The new search engines. Chatbots like ChatGPT or Gemini they are displacing search engines traditional when it comes to search for specific information on a topic or even a much longer explanation. Even Google itself he is taking it to the kitchen to change the way we interact with the internet. If before we asked Google what could be causing a headache or what could happen to us if we took an expired medication, now the quickest, simplest and most accessible way is to have a conversation with the AI ​​as a “know-it-all” to have the solution to all our questions and concerns. Even with those that have no answer, like Gordo’s winning number. A digital superstition. The infinite possibilities of AI are leading us to use it in quite peculiar ways. From have a romantic relationship with her until resorting to it to replace psychological therapy or even interact less with other humans. In the case of the lottery, just as there are gestures associated with good luck, such as passing the tenth over the belly of a pregnant woman or the figurine of a Virgin, asking ChatGPT to choose a number for us is a new digital superstition. Another space to which we have also opened the door to artificial intelligence, “just in case” is right.

It was a huge failure that now has another chance

At the end of August, ‘Gran Turismo 7‘ received a update. The video game of PlayStation 5 He received five sports cars with the peculiarity that one of them was a minivan and, in addition, it was a huge commercial failure 20 years ago. It is about the Renault Avantimea very beloved model in some circles that took over a French company that manufactured sports cars and of which some 8,500 units were manufactured. Curiously, it is an ideal car for the United States, and now that it turns 25, it will finally reach that market due to a controversial import rule that was born due to… Mercedes. Minivan coupe. Let’s go with a little story about the Avantime which, as its name suggests, was a car that was born before its time. Presented as the CoupéSpace In 1999, Renault’s idea was to combine the spaciousness of a minivan with the sportiness of a three-door coupe. Manufactured by Matra (a company that was born in the 1940s as a sports car manufacturer), the Avantime began to be sold in 2001 with a single engine: a three-liter V6 with 207 HP. Then other engines came out, such as the 2.0 with 163 HP with turbo and the 2.2-liter, 150 HP diesel. The door The car was a boat: 4.64 meters long (a lot for its time, currently compact), 1.63 meters high and a great aerodynamic coefficient if we take into account its size. It weighed a lot, and much of the blame was on the two huge doors, 1.40 meters long and 50 kilos each. To open them without looking like the wings of an airplane, Renault and Matra engineered a double hinge that “folded” the door at another point. Your market? Europe, although it had all the earmarks of being an ideal car for the United States. Mercedes and the gray market. Renault never officially launched it in the North American country, but you might think that if someone liked it, they just had to buy it, homologate it and that’s it, right? That is, like this It has been made in Europe with some units of another recent commercial fiasco, the Cybertruck. Well no, and it all comes from Mercedes that began to be sold uncontrollably in the 70s. During that time, the United States experienced a boom in vehicle imports in the gray market. Americans discovered that they could buy European cars directly in Europe at prices significantly lower than those the Europeans themselves officially sold in the country. It is estimated that, in 1985 alone, 60,000 European gray market vehicles entered the US, and a fifth of registered Mercedes they were importing of Europe. The roof had to weigh a quintal The 25 year rule. The Germans, with an official presence in the country, were not amused because, furthermore, the cars being sold did not come directly from a European dealership. Mercedes herself did the test buying a model on the gray market, the 500SEL from 1985. It was a model with airbagsbut what they received was the ’84 model without airbags and with parts added later in a non-approved manner. Citing security reasons, and because the practice was harming the market, the company spent millions trying to push through Congress a law that would stop the private importation of vehicles that were not officially destined for the US market. They won: in 1988 approved the Imported Vehicle Safety Compliance Act that prohibited these imports. There was one exception: vehicles over 25 years old would be considered classics and would therefore be exempt from the restrictions. Come on, it was not so much an issue of road safety as of preventing gray market sales from taking away part of the pie. Logical reason, on the other hand. Ahead of its time. That those stipulated 25 years will be fulfilled in 2026 means that Americans, those who like wide carsyou will be able to enjoy some of the most unique European creations of recent years. And seeing how the market is, in which it seems that if you are not an SUV you are nothing, surely one of the most unique of the times to come. Furthermore, that original version with the V6 gasoline is the most interesting version for that market. We will have to keep an eye on whether they begin to import some units that, why not say it, are not too expensive considering how scarce the model is due to the morrocotudo failure it was for the French. Specifically8,557 units were produced (taking into account the three engines) of the 80,000 they wanted to manufacture because they had difficulties with the doors and the heavy roof (a lot of glass and no pillar), but it would not have mattered: they sold very little because, in addition, it was an expensive car. In the United Kingdom it cost 24,000 pounds in 2022 and only 450 units were sold in the three years that it was available. This slap impacted Renault, but it took out a Matra Automotive that depended directly on the production of this car. I have to admit that I never liked it, but my partner Alberto does have his eye on a model that, beyond taste, is unique. So much so that even Renault itself has put him in his place.

Madrid has been filled with great fortunes and not by chance: it has known how to play its fiscal cards better than anyone

During the last decade, Madrid has become the epicenter of money in Spain. Not only does it concentrate the headquarters of large companies and banks, but it has also become a magnet for large international and national fortunes. According to a study published by Fernando Rodrigo Sauco from the University of Zaragoza, based on the latest data from the Tax Agency, 41.9% of taxpayers with assets exceeding three million euros live in the Community of Madrid, compared to 22% who resides in Catalonia. A tax shelter within Spain. The high-net-worth migration trend analyzed in the study is not new, but it has intensified over the years. Since 2011, thousands of large fortunes have moved their tax residence to Madrid. The main reason why millionaires have gathered in the capital It is due to a more permissive tax policy with large wealth groups and the network effect of living close to where the wealth is concentrated. business and financial activity. What began as a tax difference has become a true geography of money within Spain. In Xataka 64% of Spaniards believe that they pay more in taxes than they receive from the State. It’s actually the other way around The rich live in Madrid or Catalonia. The report data indicates that 58.3% of the 1% of the richest population in Spain reside in Madrid (32.51%) and Catalonia (25.8%). Further away we find the Valencian Community, with a census of 9.76% of the country’s great fortunes, and Andalusia with 6.71%. However, if the bar is raised to the highest decile of the ultra-rich population –rich among the richest— which corresponds to 0.1% of the population, then the concentration is even more pronounced, with 68.59% of these great fortunes residing in one of the two communities, but the differences are beginning to be appreciated. In Madrid the percentage of ultra-rich increases up to the aforementioned 41.9, while in Catalonia they only amount to 26.69%. The presence of these ultra-rich residents in other communities remains more or less in the same proportions as that of the rich, with 8.2% in the Valencian Community and 6.31% in Andalusia. In Xataka Tell me where you live and I will tell you how much money you have: this is how wealth is distributed in the neighborhoods and municipalities of Spain Rooting conditioning. The study analyzes the conditions that can be decisive for a great fortune decide to pack your bags and move to the capital. This is what the study calls “migration elasticity” and defines, for example, the number of millionaires who would move if a certain tax (such as wealth tax) increased by 1% more or was reduced by the same proportion. In summary, what weight would taxation have in the decision over other factors such as roots, family, language or public services. In this context, until fiscal 2023Madrid maintained a 100% bonus on the wealth tax, which in practice means that the great fortunes residing in that community They did not pay that tribute. In the rest of the country, the tax can reach up to 3.5% of net assets. Added to this is a somewhat lower personal income tax in the upper brackets and the absence of inheritance tax for direct inheritances. Therefore, taxation gained weight in the decision to change residence. {“videoId”:”x8k9arv”,”autoplay”:false,”title”:”You could be LOSING MONEY with your 2022 INCOME RETURN”, “tag”:”Webedia-prod”, “duration”:”402″} A paradigm shift. The result of this tax policy that is friendly to large assets has been clear: between 2011 and 2015, more than 6,000 large fortunes moved to Madrid. According to the study, that flow remained constant over the next decade. However, in 2023 a differentiating factor came into play, the effects of which are not yet known: the entry into force of the temporary solidarity tax on large fortunes. This new tax applied a rule in which, with the excuse of avoiding double taxation, the State began to collect wealth tax that the communities that had it subsidized were not collecting. According to a report According to the Tax Agency, the 27.6% of large fortunes who paid the Wealth Tax in 2022 rose to 99% in 2023. Skyrocketing its collection in Madrid and Andalusia, where it was previously subsidized. That is to say, that tax advantage that previously conditioned the concentration of capital in Madrid has been diluted. In a few years we will see if this paradigm shift once again conditions the residence of the great fortunes.

For the first time in many months, there is a chance to see a truly strange event: real rain

This story begins with a pinch of hope. In recent days, the main meteorological models were beginning to agree: the interaction of a deep trough and a subtropical low that would generate a fairly active front. In other words, for the first time in a long time, real rain could make its way to Spain. Not even Danasnor summer storms: real water. The problem? That, actually, that They were just a handful of exits. deterministic and considering that autumn has always been (and will be increasingly) infernally difficult to model, that was very little. It doesn’t mean, of course, that it won’t rain. It’s going to rain, but the doubts are enormous. Although, as the cards are dealt, it all starts to make sense. But what is going to happen? According to AEMETFrom Monday to Wednesday, the rain will be concentrated in the northwest of the peninsula. However, only in Galicia will it be persistent and there will be significant accumulations. On Thursday the situation will become more “democratic” and the rains will reach a good part of the northwest, the center of the Peninsula and the Pyrenees. The wind can be very strong. However, real rain (as “real” as it can be in this situation) in the center will have to wait until Friday. Beyond Friday everything becomes more diffuse, some rain is expected in the interior, in the south and in the Balearic Islands. And, almost certainly, a small drop in temperatures followed by another rebound. One that will leave us better than we were, yes; but with temperatures above normal. And then? In reality, everything seems to indicate that these meteorological skirmishes will be little. And, given this, many experts already they begin to put their hopes in December. That’s bad, yes. It is true that the country’s reservoirs they are much better not just last year, but the average of the last ten years. But this “water cushion” will not last forever and, although we tend to forget, autumn is a particularly important season for reserves. “in general terms, autumn usually registers higher accumulations than winter in our country as a whole”, said Yurima Celdrán. If we lose it, we will be facing the next drought with one hand tied behind our back. And going to December to wait for a ‘miracle’ is not positive at all.

Chance or not, Tesla has collapsed in the stock market at the same time that its great rival has shot: byd

Like a rocker. Like the communicating vessels that claim to be Barça and Madrid. As, the most Chinese, concept of Ying and Yang. Or as the most Spanish, said of “the two sides of the same currency.” Byd and Tesla seem to be in completely opposite points. Just when one seems to have Detwered And it does not stop presenting new solutions for its vehicles the other seems to be completely stagnant in the launch of new proposals. When one has taken off the other one in a clear setback. We do not know what will last but what is clear is that, at the moment, photography for Byd and Tesla cannot be more different. Two completely different scenarios It is enough to review the last six months of Byd and Tesla to verify that the situation cannot be more different for both companies. From Tesla’s point of view, if we look back half a year we find that the company was about to enter a roller emission mountain. In October 2024 Tesla presented what he aspired to be a blow on the table. Your promise: a robotaxi without pedals or steering wheel which should be sold from 2026 for 30,000 euros. Although doubts emerged at first given Cruise and Waymo’s performance In the autonomous driving market and the mountain of money burned along the way, Donald Trump’s choice shortly after An unexpected impulse To the company. Despite contraintuitive, choosing a president who seemed contrary to the electric car was A good way to keep Tesla at the top… from the United States. Because The actions shot But the data has ended up clicking the bubble. First with the confirmation that Tesla He could not sell more cars in 2024 than the previous year. Second because 2025 has started horrificly For Elon Musk’s company. And, third, because the falls are more pronounced in the countries that buy the most electric, such as China and Germany. To all of the above you have to add a reputational crisis of the company as a consequence of Elon Musk’s political decisions. The real impact is not very clear in their drop in stock market but that social networks have been filled with people denying the company or attacked vehicles and concessionaires Because of the decisions of his CEO they do not seem to help at all. If we look Stock performance Six months, the company seems to have been stagnant above the border of the 200 dollars/action. Its value remains very high and a setback of less than 4% does not seem too much but the growth and subsequent adjustment have been so accused that they do not invite to be optimistic either. On the contrary, the performance of byd Six months seen is very different. His actions have grown 55% and in the last year they have shot above 80%. And in recent months the wind blows in favor of the Chinese company. It ended 2024 with the aim of reaching Tesla as the company that sold the most electric cars. He did not get it for little But the smile was not frozen for a long time. The company managed to place itself as The fifth manufacturer who sold more cars In all 2024. a figure in which only plug and electrical hybrid vehicles are contemplated or, as they are called in China, new energy. Unlike others rivals like Saic Or the Geely group, all byd cars take advantage of electricity so they have it more complicated in markets such as Spanish where cheaper and pure combustion cars triumph. However, the prospects for 2025 invite you to be optimistic. The company has sold almost double in the first two months of the year as in the same period of 2023. It is determined to find soil for new factories. In America I intended Install in Mexico But he will have to deal with the restrictions of his own country. In Europe they are already clear that This same year They will decide where they will raise their third floor on our continent (If we count the Turkish as the second of its expansionist plans in Europe). And in China they do not stop launching products to each more striking. If the Chinese electric car market were the Barcelona Club football we could say that they are month than a car. To continue attracting customers, for example, a platform for launch and record you driving. Beyond this curiosity, the real announcement was the confirmation that they will give away their Eye of God In all its vehicles. This is a missile in Tesla’s flotation line. Elon Musk’s company intends that its functions of driving or Autonomous driving (in the future) Be a more source of income. Byd they argue that they are a purchase value in itself and prefers to give them them thinking that the business can be make profitable with other services To enjoy when your eye of God is active. To the latter you have to add your new platform. The Super E-Platform is already ready to ride in its two larger cars and price. The incentive in this case will be his very quick loading times. Next to this platform, the company presented new recharge stations. The combination of both products should be able to load electric cars with peaks up to 1,000 kW. That is, the power that had so far been thought to recharge electric trucks. With such a charge power, Byd says that 400 kilometers of autonomy can be recharged in five minutes. The recharge time would be matching the time we spent pouring gasoline. This last announcement has served the company to receive a tremendous push in the stock market. In what we have been, their shares have risen almost 13% and strengthens the sustained growth of the last year until its historical maximum. It remains to be seen if Tesla manages to recover and get out of the stumbling block in which … Read more

They are your best chance against China

The Japan government has announced that it will invest 200,000 million yen (about 1.5 billion dollars) to accelerate the development and commercial production of Perovskita solar panels, a technology of Japanese origin that could be their best opportunity for Challenge China in the global market of renewable energies. The bet is monumental. With this strong public investment, the Japanese authorities seek that the production of photovoltaic cells of Perovskita is equivalent to the capacity of 20 nuclear reactors by the year 2040. To achieve this, the Perovskita would mean a paradigm shift in the energy economy of Japan and the global geopolitics of clean energy. Light, flexible and very Japanese. Perovskita is a crystalline material with the ability to absorb a lot of light which can be manufactured in ultrafine layers based on raw materials more affordable than silicon. Perovskita’s solar cells were invented by Japanese scientist Tsutomu Miyasaka while working in Fujifilm. Japan Bet on movies of approximately one millimeter thick. One of the greatest values ​​of this type of panel is its versatility. Due to their fine thickness and reduced weight, they can be installed on complex surfaces, such as roofs with little load capacity, buildings walls, transport stations or even vehicles. In a country with such little flat and usable land as Japan, these advantages could be decisive to boost solar energy beyond the large traditional photovoltaic parks. The equivalent of 20 nuclear reactors. Japan has marked a very demanding calendar. The goal of producing energy equivalent to 20 nuclear reactors by 2040 is framed in the commitment that between 22% and 29% of the country’s total electricity generation comes from solar energy by then. At present, solar energy represents only 10% of its energy mix. To fulfill this road map, the government has granted subsidies of up to 1 billion dollars to Sekisui Chemicalone of the leading conglomerates in the development of Perovskita. They add up to the 500 million dollars already invested in the research and development of technology and other funds that would ensure the supply chain. Iodine is an essential component in the manufacture of Sovskita and Japan solar cells is one of the world’s world producers. The technical and economic challenges. One of the biggest technical challenges for Perovskita solar panels is moisture degradation. Sekisui He says he developed a sealed with specialized resins to prevent water between and accelerate deterioration. As for the economic challenges, the main unknown is how long it will take to lower manufacturing costs to competitive levels, taking into account that producing flexible Perovskita panels is between three and four times more expensive than making crystalline silicon panels, which have been lowering the price year after year thanks to the Huge production capacity of China. Japan hopes that thanks to mass production, the price of these new panels will become comparable to that of traditional ones. Reduce China dependence. In the end, it’s about that. China leads overwhelmingly the manufacture of solar panels conventional silicon, concentrating about 85% of the global production of photovoltaic cells and about 80% of the polysilic that they use. Japan, like other countries, depends largely on Chinese technology. The defenders of the Japanese bet see in the Perovskita a historical opportunity to break that hegemony. This material dispenses with silicon and uses iodine, whose main world producer, next to Chile, is Japan, thus reducing bottlenecks and dependency risks. Not only Japan develops Perovskitas. China too He is trying to win Japan In his own game. There are different variants of Perovskita and, while Japanese laboratories put all their efforts in ultrafine and flexible films, China has quickly advanced in hybrid models (more efficient silicon-butrovskite tandem cells) with thicker glass coated glass modules. Although both regions compete with the same material in mind, the market could end up segmented in applications: in Japan, covered and facades; In China, large solar parks or double -layer panels for urban environments.

If today we can see a planetary alignment it is because the entire orbit solar system in the same plane. And not by chance

Tonight we will have a chance to see one of the astronomical events of the year, The great planetary alignment: Seven planets (all the major planets of our solar system) will be visible in the night sky. To understand why this phenomenon and discover what it is and what is not, it is convenient to keep in mind some details about the dynamics of our solar system and its history. That is, the very story of the planets that accompany ours in the orbit around the sun. Ecliptic. The name of the phenomenon itself, Planetary alignmentindicates that it is an event in which the planets are arranged in a row. However, we must bear in mind that when we talk about this we do not talk about the planets forming a precise row in their orbital displacements as in textbooks, nothing is further from reality. The alignment of the planets refers to the fact that, at some point, these appear aligned in the night sky, that is, it is an apparent alignment from our terrestrial point of view that occurs around an imaginary line that crosses the night sky. This imaginary line is the ecliptic, but in reality it is much more than a line marked by the planets. And it is that most of the objects of our solar system move through it. Even the stars seem to move following the path that this brand. From the album to the planets. Strictly, the ecliptic It is defined as the imaginary plane that contains the orbit of the earth around the Sun. That is why this imaginary line is marked by the movement of our star in a daily transit by the celestial vault. However, due to the fact that the orbits of planets, satellites and asteroids of our solar system orbit in different planes, the ecliptic and its surroundings become the projection in the vault of the sky of an album, the disk formed by all this infinity of orbits of objects that rotate at different distances already varied speeds but practically always in similar planes. It is no accident that almost all the subject of our solar system is presented on this album. To understand the reason, we have to go behind in time, to the formation of our solar system, to the era in which around our star there were no planets, but a Protoplanetary disc. Return to the origins. The origin of the solar system is in a cloud of gas and matter that ended up concentrating. In doing so, Due to the conservation of angular momentumthe cloud was taking one more disk appearance, turning at the same time on itself. The center of that cloud continued to concentrate, until it reached critical mass and density for the formation of a star, the sun. The rest of the album was orbiting around the sun, now like a ringthe so -called protoplanetary disk. The dust also began to concentrate on different points of this album also due to gravity. Progressive clashes were giving rise to increasingly large concentrations, dust that became increasingly large rocks until planets and asteroids were formed, all still turning in the same direction in which millions of years ago revolved the protoplanetary disc and, before, the original cloud. The movement of the Earth. There is another factor that contributes to all objects from heaven to seem to scroll in unison and it is the fact that the Earth’s rotation axis is aligned with the axis of rotation of its orbital movement. This is more or less common, although there are exceptions such as Uranus. If we were on this planet, we would see night after night that the stars distant to us move from this to west normally, but the solar ecliptic would move very differently, a more exaggerated version of the solar movement given in the polar circles, with a seasonal cycle of days and nights. This implies that in summer, the ecliptic plane would be a circle in the celestial vault, something very different from what we perceive from Earth.

NASA ends up announcing that this large asteroid has a 1% chance of impacting with the earth. That is not normal

At the end of March last year, NASA launched a very special statement. The agency came to say that the biggest object that will happen near the earth will be An asteroid that will approximate 32,000 kilometers And it can be seen with the naked eye on April 13, 2029. A few hours ago, NASA has given another “those” news. They have found a meteorite distinct To all we know. YR4: Impact risk. As we said, NASA has issued a statement About an asteroid called as 2024 YR4 Discovered at the end of December 2024 by the Atlas system in Chile. This object has drawn attention because it presents a probability of impact superior to all recent meteorites: 1% for December 22, 2032which makes it one of the asteroids with the greatest potential risk of collision registered to date. With everything and as we usually say in these cases, this estimate will possibly change as new observations are made, with expectations that the probability of impact decreases. Classification and risk. The asteroid has an estimated size of between 40 and 91 meters in diameter, similar to that of the object that caused the Tunguska event in 1908. Therefore, currently It is classified at level 3 of the Torino scaleindicating a real probability of impact that merits monitoring, although, again, its level is expected to be reduced as more data will be obtained. This scale, used to evaluate the risk of asteroid impact, goes from 0 (without danger) to 10 (catastrophic collision). In any case and for us to get an idea, before this finding there was no recorded asteroid with a score greater than 0 on the Torino scale. Closeness and probabilities of impact. The closest step of 2024 YR4 is estimated at 0.00001 Astronomical Units (AU) of the Earth, which is equivalent to 1,500 kilometers away, that is, closer than many satellites in terrestrial orbit. At the moment, The impact probability is 1 in 83 (Approximately 1.2%), which has generated that concern in the scientific community. However, and although we look repetitive, it is important to underline that the experience with similar asteroids indicates that these probabilities usually decrease after more analysis. Precedents There have been cases of asteroids that have reached higher levels on the Torino scale and were subsequently discarded as threats. An example is 99942 apophis, which in 2004 reached level 4 due to a probability of 1.6% impact in 2029, Although subsequent studies eliminated any risk In 2029, 2036 and 2068. Therefore, it is feasible to think that asteroid 2024 YR4 in the future is reclassified at level 0 As their orbital calculations are related. Possible consequences and monitoring. To put ourselves in the worst of the stage, with a possible impact, 2024 YR4 would not represent a global extinction event, but could cause significant damage if impacting a populated area, similar to the famous Tunguska event that swept a vast region in Siberia. Therefore, NASA and other space agencies will continue to track their trajectory and refine the calculations to confirm their destination. Although The American agency has emphasized its statement that the probability of impact is still low (about 1%) and that this type of initial evaluations tend to be corrected over time, also ends up underlining that it will adjust its predictions ensuring that any potential risk is properly evaluated and, if necessary, addressed With planetary defense strategies.
