Those who understand it end up being their greatest enthusiasts

by

Imagine that you ask for Chatgpt either Gemini A poem, a recipe or a summary and the answer appears polished on your screen in seconds. Now ask yourself what happens behind: Models trained with millions of datareal -time inference processes. Those who understand this mechanism usually look at AI with more skepticism; Those who do not understand it so well tend to see it with greater fascination. A recent study suggests that this difference in understanding helps explain who adopts it with more enthusiasm. The usual thing with the new technologies is that the first to adopt them are the ones who understand them best. With artificial intelligence the opposite occurs. An investigation published in Journal of Marketing By Stephanie Tully, Chiara Longoni and Gil Appel shows that people with less literacy in AI are usually the most enthusiastic when using it. The finding is repeated in different contexts and countries: the less it is understood how it works, the more fascination generates and the greater the willingness to incorporate it into the day to day. When understanding less means getting more excited As WSJ points outto reach these conclusions, the authors deployed a battery of studies in several phases, with surveys and experiments carried out in 27 countries. In addition to evaluating concrete tasks, they measured literacy in AI with their own instruments, such as a 25 -question questionnaire, and with a 17 -question test prepared with two AI systems. In one of the experiments, 234 university students indicated whether they would use a free tool for academic work that went from analyzing the beginning of World War I until writing a romantic poem. The pattern was consistent: the lower the technical knowledge, the greater the willingness to use it. According to the authors, the link between low literacy and enthusiasm is not explained because I believe that AI is more capable or less dangerous, but by how its operation is interpreted. For those who do not know the technical details, seeing a system generating creative content can be surprising and even mysterious. That feeling of magic awakens curiosity and trust, which makes these tools more attractive. Researchers add that this relationship is not linked to valuations on the ability of AI, ethical judgments or the fear of its impact, but precisely to that aura of “magic.” The work also emphasizes that this pattern does not mean that the fascination with AI is universal or disappears when understanding its functioning. Those who have more training They tend to see algorithms where others see magicwhich does not imply disinterest, but a more critical approach. In addition, the results reflect general trends and enthusiasm can vary according to the context, the type of task and the user’s previous experience. The study does not intend to simplify the debate, but to provide data on how we perceive these technologies. Researchers point out that these conclusions may have direct applications for companies that develop AI -based products. Identifying users with less technical knowledge as a more receptive audience can help design more accessible marketing and use experiences. At the same time, they warn that feeding the mystery of these technologies can be counterproductive: the more opaque a tool is, the more difficult it is to build long -term confidence. The challenge is to balance curiosity with transparency on how systems work. The study suggests that amazement is an effective entrance door to artificial intelligence, but does not replace knowledge. Learn how these technologies work Help recognize its risksvalue its benefits and make more informed decisions about its use. For users, familiar with technical foundations is a way of continuing to explore without being carried just by novelty. The fascination can continue there, but accompanied by criteria, which in the long term allows a healthier and more productive relationship with AI.

Google has been saved from guillotine thanks to its greatest threat: chatgpt

by

The judgment In the case of the United States against Google, published yesterday, it is one of the most important in the history of the world of technology. And in it Judge Amit Metha, in charge of the case, mentions 133 times the same word. Ia. Three years ago this sentence would have been very different, and there would probably have not had a single mention of that acronym. But the launch of Chatgpt in late 2022 has changed everything, and has caused a surprising consequence for Google. Despite having confirmed that it has a monopoly in the searches business, The punishment has been soft. Almost benign. Google will not have to sell Chrome As the accusation demandedand instead the judge has forced the company to share search data with its competitors already limit – but without prohibiting them – the exclusive search contracts that it maintains with companies such as Apple. The result of the trial is clear: Google has won, especially since it has lost much than what I could have lost. AND The great responsible for that legal triumph is not even Google, but chatgpt. Already in the introduction of the sentence, on its first page, the foundations of that decision are made clear: “Google is still the dominant firm in the relevant product markets (search). No rival has managed to fight with Google market share. And no new competitor has entered the market. But artificial intelligence technologies, in particular the generative AI (” Genai “)) can end up changing the rules of the game.” From there the sentence speaks of how generative technologies have been increasingly integrating into traditional search engines. It is something we saw first with Perplexity and that has ended up changing the search experience of the same Google. Chatgpt, the unexpected Salvador de Google From the results page with a list of links we have moved to a page in which more and more often The first thing that appears is an AI overViewan answer generated by AI and built directly from different sources. He NEW AI MODE It goes even further and raises the future transition from the traditional search engine – you are questions, he generates link lists – to one with whom we will talk. The AI has entered as an elephant in a potsweeping everything, and searches have been especially impacted. We are many who started using much more chatgpt, Claude or Gemini than the traditional Google search engine or some of its rivals, and that reality has been reflected in the sentence: the search engine, as we knew it, is becoming something else, so the classic search engine is no longer “so dangerous.” In fact, this sentence is from that very reasonable point of view: the AI ​​boom is creating such competition in the searches market to force Google to make drastic structural changes – such as selling Chrome – seems unnecessary. Of course, that does not make the sentence be content. Gabriel Weinberg, CEO of Duckckgo, believes that Google’s privileged position will continue to benefit and prevent free competition. In A shared statement in X He explained how “Google will continue to continue using their monopoly to stop competitors, including searches with AI.” Tim Sweeney, CEO of Epic, went further and criticized the punishment that justice had imposed to Google, considering it absurd and raising an analogy of the most suggestive: “It is as if a defendant had stolen a series of banks and the court’s verdict had declared him guilty, and then he had condemned him to probation, by virtue of which he could continue to steal banks, but he would have to share information on how he does it with other thieves of competition banks.” It is an interesting way to see that sentence, of course, but it is clear that sharing that data from your searches – Gogle has already warned that will review that decision– Open a door to more competitors. Not only that: it raises changes for the panorama of future search engines, including those with whom we will not stop talking. Chatgpt, the unexpected Salvador de Google, included.

Nano Banana is not just a great creator of images with AI. It is the greatest danger to Photoshop and company

by

Google has been playing hiding place with what is a great threat to Photoshop, at least in its photo editor facet. For weeks, a mysterious tool called “Nano Banana“He has been appearing anonymously into test platforms, leaving amazed professional users. Google finally confirmed that this experimental model is yours and is integrating it into Gemini. Why is it important. We are facing the beginning of the end of the layers, masks and tools that have defined digital design for 30 years. You change the color of a shirt without distorting the face. You add elements without reinventing the background. In 2 seconds, no 15. For professional uses it is not ready. For first sketches or for domestic use, it is perfect. 10 Google applications that could have triumphed The difference is persistence. Other models generate from scratch with each Promptbut Nano Banana remembers. You can strain about the same image dozens of times. Some examples. Let’s see what can be done with Nano Banana (if you want to know how to try it, We have prepared a guide). Everything has been done are the Prompts that we attach, without more. Original photo: “Create an image with this man but in a Valencian people of the 50s, with clothes, appearance, hairstyle, environment, etc. that are credible for the time.” “Now in the 2050 futuristic Shanghai.” “Now he returns to the original photo and adds this man by his side, posing together for the photo.” “Now back them as two Roman gladiators in the amphitheater.” Let’s go with something else. This Apple announcement in Las Vegas, deployed a few years ago. “Modifies the announcement text to say ‘2×1 in all iPhone models until the end of stock’”. Another different. We give you these two images. “Put this man the red shirt that attached to you.” “Now place him in Mestalla.” “Put a black cap and remove the clock.” All at the blow of Prompt And very fast, more than chatgpt. The money trail. Nano Banana has a cost of $ 0.039 per image of 1024 x 1024 pixels. Adobe has already announced that he will integrate the model in Firefly and Express, as reported Business Insider. His argument (“we offer all the models in one place”) makes sense, although something defensive also sounds. Those who pay dozens of dollars a month for a license to make editions will begin to be renewed. Now it is possible to generate Mockups In minutes, not in days. Some Ecommerce They will stop needing so many photographic sessions. A teacher can create a better adapted diagram than that of publishers. Everything with Prompts of text.

Asturias prepares the greatest experiment in Spain to reduce the day

by

When the national debate seemed focused on (still stagnant) Reduction of the working day At 37.5 hours a week, Asturias has decided to step on the accelerator. The Principality government has launched the machinery to launch an experiment on the four -day work week in the region, a movement that resurrects one of the Conversations about the future of work in our country. The first step have already taken it. From the regional government They have already tendered The study that will serve as a road map in this ‘experiment’. The objective they have is clear: analyze the viability and The economic impact to implement a 32 week weekly day in the business fabric of the region. A necessary study to be a success. This study, which will have a value of 16,862 eurosan external consultant will be held. In its content, what is going to be collected will be the similar projects that have been made in other regions, with their failures and their mistakes. In this way, we will not try not to fall into the same stone again as other autonomous communities or other regions of the European Union. In addition, it will also identify the key sectors of the Asturian economy where it would be more feasible to apply this reduction in working hours, and especially where there will really be a benefit of having a four -day day. From there, the assessment of unions, employer and company will be collected to have a complete vision of the consequences that this measure can have. When it will be launched. Once the report has been launched in tender, the manager who manages to get him will have a period of three months to be able to collect all this information, so we can easily leave the next year. When you have all this information, it will be when the Government will propose to companies the possibility of joining this initiative. The main focus will be in the private company. Sources from the Ministry of Science, Industry and Employment They have detailed To El País that the objective will be the private company in this experiment. Although they will also analyze the viability in the public company. But what is clear is that participation will be voluntary, as detailed in the agreement signed between the regional government with the employer and the unions. In these same statementsthe Ministry suggests that this model make Asturias one of the first communities to apply this labor model, aspiring to be one of the greatest experiments in Spain in this area. All this because so far the projects that have come forward have focused on very specific areas of a province or have been a failure, as in the case of the Plan of the Ministry of Industry. The great debate: how will affect salary. Logic can mark that a reduction in the number of hours worked It also carries a reduction in monthly salary. But this is something that at the moment is not clarified in the position by the Principality. As they point out, there is a “varied casuistry” and that, in the absence of a national regulation, it is an “issue to negotiate in each labor relationship.” Precisely, the study that has been in charge will be focused on shedding light on how this problem with companies should be solved. There are a history in Spain. To see similar projects we can go to Valencia in the spring of 2023, where the City Council of the capital tested the four -day week turning on Mondays. The results In this case they were very positive, since an improvement in the well -being of employees was evidenced. Although he also had a negative impact on some businesses by losing this habitual clientele of Mondays. Nationally, the Ministry of Industry launched in 2022 With a budget of 10 million euros in grants A plan to reduce working hours. But it was a disaster, since Only 41 industrial SMEs requested participatingand finally, almost two years later, only five companies were approved, reducing the investment to 500,000 euros. In Spain the regulation will still take to arrive. Although the Council of Ministers I already gave green light To the legislative text that would come true to have a 37.5 hours day in Spain, you still have to wait. His passage through Congress is being torpedored, since for the moment does not have enough support To be published in the BOE. Although the reality is that although it seems A substantial changethere are many companies that collect it in their collective agreements and Other EU countries They have a day below what is raised.

The US wants China to become addicted to Nvidia chips. His problem is that his greatest rival is not for the work

by

The administration led by Donald Trump has realized that her predecessor and herself have made a very serious mistake. SANCTION PACKAGES that have deployed during the last three years To prevent China from doing with the most advanced semiconductor manufacturing equipment, and also with avant -garde chips for artificial intelligence (AI), have forced the Government of Xi Jinping to become independent of foreign technologies. The Chinese industry of the integrated circuits has advanced a lot during the last five years, and will surely continue to do so. It is very likely that in 2026 Chinese manufacturers have their own extreme ultraviolet lithography equipment (UVE). And currently Huawei, Moore Threads and other Chinese companies have GPU for some scenarios They compete with the Nvidia and AMD chips. The independence of the Chinese semiconductor industry is underway. The best output given this juncture for the US is none other than to deliver to China in a controlled way advanced chips for AI, but less powerful than the most capable that design Nvidia, AMD or brains. In this way this Asian country may relax a bit its ambition for development and independence. This is exactly what the Trump administration is doing by allowing Nvidia to give back to its Chinese clients Your GPU for IA H20as Chris Miller holdsthe author of ‘The chips war’in his Newsletter. China is getting out of Nvidia The future of Nvidia in China is largely in the hands of the administration of the cyberspace of China, known as CAC for its English denomination (Cyberspace Administration of China). This institution is the main Internet regulatory body in China and is thoroughly investigating NVIDIA H20 GPU Because it suspects that this chip could incorporate a back door of difficult location by Chinese experts. If so, the possibility of China to use this GPU could be possible. David reber Jr., Nvidia Security Director, published last week An article in the blog of this company entitled “There are no rear doors in the Nvidia chips. There are no deactivation switches. There are no spy software” in an obvious attempt to defend the company’s reputation and appease the growing distrust to which he faces in China. There is a lot at stake. If the final resolution of the CAC turns out to be unfavorable with all probability NVIDIA will lose a good part of the income currently obtained in this country. The Chinese government is urging Chinese companies that are dedicated to the development of large models of the use in their Chinese chip servers However, this is not all. Whatever the CAC verdict is a fact that the Chinese government He is urging Chinese companies that are dedicated to the development of large models of AI to use in their servers integrated circuits of Chinese origin. In this scenario their best bazas are now Huawei and Moore Threads. The first of these companies has lists its own GPU for iathe chips ascend AI, for more than five years. During this period of time it has been refining them and increasing their abilities with the purpose of matching or even overcoming the performance of the chips A100 and H100 of Nvidia. His most ambitious proposal right now is the chip Ascend 910dwhich seeks to overcome the performance of the H100 GPU. However, this Chinese company has also recently presented its chip Ascend 920a solution that is clearly destined to occupy in the Chinese market The H20 GPU space. This proposal will enter large -scale production during the second half of 2025 using 6 NM integration technology that have presumably developed elbow with Huawei elbow and SMIC. On the other hand, Moore Threads He has developed several GPU for AI applications that, on paper, rivaize some of the advanced solutions that have placed in the Nvidia, AMD or Huawei market. The MTT S4000 and MTT S3000 cards are its most interesting proposals right now, although, curiously, in its porpholio the MTT S80 card, a proposal for games and content creation that, according to Moore Threads itself, has a 14.4 TFLOPS calculation capacity also appears in Floating Coma operations of simple precision. It doesn’t impress, but it’s not bad at all.

The countries with the greatest natural gas reserves, gathered in this graphic developer

by

Natural gas has become a bridge fuel on the road to decarbonization. Emits less dioxide that coal or oil when used to generate electricity, and in a world that is hitting the Volantazo to renewable energiesgas has established itself as a vital element. Reason? Is being used to feed the voracious data centers And, in addition, it is A geopolitical element. And there, countries with the largest natural gas reserves have a lot to say. And that mixture between natural and geopolitical resources can be seen perfectly in this graph elaborated by Visual Capitalist: The powers. Russia, Iran and Qatar are the indisputable powers when we talk about natural gas reserves. The United States stays close, but the first three, according to these data from the US Energy Information AdministrationThey represent 51% of those world reserves. And the first ten countries, which are represented in the graphic, accumulate 83% of the total natural gas. Russia is the clear clear, with twice more than Qatar and almost tripling the reserves of the United States. The closest is Iran, Another oil power. Protagonist role. And who controls gas, controls a large percentage of the world energy cake. It is estimated that, currently, natural gas represents 23% of the global energy mix. This depends on the country, of course, but one of the largest whales is the United States and there represents 40% of the electricity generation. The reasons are the amount of and efficiency, being your Great advantage which is the most ‘dispatchable’ energy source. It can be activated and deactivated easily and, in a matter of minutes, operates with a capacity greater than 80% to satisfy demand peaks. In addition, what we have already commented: its emissions Co₂ are approximately 50% lower than coal and 30% lower than oil. Trend. The graph represents the status of reservations in 2023, but with more recent data, we see that it is still an essential fuel: Natural gas meant 33% of the increase in world energy supply. The demand for natural gas in 2024 increased 2.5%. Electric generation from natural gas also grew by 2.5%. Natural gas production increased 1.2%. And world trade by gas pipeline and LNG increased by 3.3%, being the first time it grows from 2021. Geopolitics. And that only a few countries have such an essential fuel for the rest, it implies that it is a source of economic, diplomatic power and, in times of crisis, also a weapon. In Europe we have witnessed this from two different fronts. Before 2022, near the 40% of European natural gas was Russian. The invasion of Ukraine caused a series of cuts in the supply and Russia He used it as a weapon in the contest‘drying’ the countries of the European Union that supported Ukraine. This has led the EU to rethink your energy safetydiversifying energy sources and investing in infrastructure such as those of the Green Hydrogen Corridor. And, in this situation, the US has gained weight becoming the largest gas exporter to Europe, using this resource in the Tariff trade war. Artificial intelligence. Beyond politics, this ability to satisfy demand peaks is something that is erecting natural gas as the most important fuel today. Data centers require something called “operational reliability”, or what is the same: they cannot stop working and They cannot depend on renewable energieswhich may have intermittent periods of activity, be their only energy source. In addition, at certain times of computational demand peaks, They need a huge amount of immediate energyand that is where natural gas can meet that demand. The energy need for these is such Data macrocentros that there are companies that are choosing to take over nuclear energy plants to meet your needs. Gas for a while. The natural gas is a complex scenario because, although we want to get rid of it in favor of renewable energies, factors such as its energy advantage and strategic pacts favor that it is rope for a while. The projections indicate That the energy demand of data centers only in the United States will grow from 180-290 twh from 2024 to 515-720 TWH in 2030. In the rest of the world, It will pass of the 415 TWH to 945 TWH in 2030. Globally, other analysis They point to an increase in that 50% demand by 2027 and up to 165% by 2030. Beyond the needs of the data centers, it is wait An increase of 32% in the world demand for natural gas by 2050, being Africa and Asia the main driving regions of this growing demand due to electrification and industrialization needs. These estimates can go to the fret if a Unexpected increase in renewables Thanks to new technologies or more efficient solutionss, or if the panorama of the data centers changes, but what is evident is that the Camino to decarbonization You will have to live with natural gas.

One of the greatest consultants has brought the war against teleworking to the extreme: a “traffic light” to control

by

PricewaterhouseCoopers multinational consultant (PWC) decided A little less than a year ago than The 100% Teleworking Era had ended. He joined the decisions that had adopted competitive companies such as EY. The striking of the movement were its conditions: it would geolocate their teleworkors to control that they were going to the office 60% of the day, the minimum amount that it now demanded (after having requested 40% until that moment). Now, thanks to Financial Times We know how they are carrying out control in their offices in the United Kingdom. Traffic lights. PWC measures have not only fallen into broken bag, but have intensified. Since April, the company is registering in a control panel the assistance and if the three days they demand at the week are passed in the office. To control compliance more visually, the company has established an indicator based on traffic light colors. Those employees who meet have a “green” in their state. The profile of those that drops from 60% has an amber, and those that fall from 40% have a red. In addition to the workers themselves, supervisors, heads of business units and directors have access to this traffic light. Thorough control. To verify that the employees go to the offices (OA meetings with customers, outside them), the company is carrying out a monitoring of the location of the wifi connections of the laptops. The data that is collected following this control is intended with the assistance or absence indicated in Workday, the software used for human resources issues, and in the personnel control sheets. In addition to the WiFi, PWC also has control of when employees pass their cards as an signing to enter and leave the offices. Policies against the old trick. The verification of assistance based on the entry and exit signings is something that many companies have carried out. Those employees who wanted to try to skip that control did something simple, according to a study: 58% of the workers employed under a hybrid work system went to the office, signed and then they left. Amazon already ended this picaresque establishing a minimum time to go to the office. Hey also reinforced Its access policies with lathes Checking that 50% of some teams breached the demands for assistance to their facilities. The control based on Wi -Fi connections is the brooch to these policies. Consequences. The question is what happens to employees who have a red or amber in their traffic light. And the internal guide for employees to which the Financial Times has accessed is clear: they face formal sanctions and a reduction of their performance in evaluations, where extra bonuses are played to their base salary. That same guide includes special exceptions or permits for family or disease reasons. Employee reactions. PWC workers are complaining so much about this scrutiny that a high -rank worker has told the Financial Times that he has lost his account of how many complaints he received. Employees are restless about tracking methods, and seek more transparency since the pressure to be fulfilled rose. It goes in the line of the best qualified employees in companies of the S&P 500: Rotation triggered by imposing face -to -face. According to a study by McKinsey, return to the office It is not enough to improve productivity. A company spokesman said that the control panel “guarantees that our people have easy access to their assistance data, so that they can manage and plan their time in a way that works for them, our equipment and our clients.” The paradox. The ‘Big Four’ have been serious with the return to the office, but they have always been in the spotlight of the management of extra hours, and Work fined them in Spain for having lacked time registration (mandatory by law since 2019) and for excess of day. The macro -inspection ended, at least 1.4 million euros that had to pay for different circumstances for social security fees.

Someone has made a ranking with the greatest fines in the history of Spain and an old suspect is in the lead: Ryanair

by

The fine imposed by the Government of Spain to Ryanair is the highest in the history of our country. The more than 100 million euros of sanction exceed all the records we had until a few months ago. To get an idea, the highest fine until then was just over three million euros. These are the most large fines and the companies that have received them. The highest. Without any discussion and without competitors. Ryanair received a sanction of 107.78 million euros last November 2024 on the occasion of his hand luggage policy. The sanction did not arrive alone and also punished Vueling (almost 40 million euros) and Easyjet (almost 30 million euros) for the same issue. However, Ryanair’s traffic volume is so high That by punishing the same fact repeatedly, the economic amount for the company is very high. So much so that, as we see, the two companies that accompanied him in it were well below the punishment to the Irish airline. Unprecedented. The list with the 15 toughest fines imposed by Spanish entities to companies operating in our country has collected Facua. This classification shows how, before the sanction to the airlines, the toughest fine had been for Unicaja and had stayed at 3.17 million euros. At that time, the Junta de Andalucía punished Unicaja in a package that extended to other banks that had imposed land clauses to their customers in mortgages. Rapier It was considered abusivehe entailed a very small fine with Ryanair’s. Despite being the first until very recently, Ryanair’s fine is 3,400%. Who appears? In addition to the aforementioned airlines, Norweigan was also part of that package and slipped between the 10 largest sanctions in our country. In between, Movistar (receivable in the time of the calls), CaixaBank (soil clauses), Vodafone (seven fraud among which is the deceptive advertising) and Endesa (for applying illegal rates for the rental of their light counters). It should be noted that, in addition, Movistar is the company that repeats the most in the ranking, adding up to three fines, the aforementioned and two other sanctions worth 1.53 million euros. Vodafone also repeats with a second fine of 1.19 million euros. Volotea, the fifth and final sanctioned airline, also appears here with a fine of 1.4 million. Banco Mare Nostrum (BNM) and Caja Rural de Granada are two other financial entities that close the breakdown. Has there been any consequence? Yes, although Ryanair has camouflaged him In response to rates, supposedly abusivefrom Aena at airports. Its response has been the abandonment or partial exit of some regional airports. A change of strategy propitious to the company And that, in addition, it has served to press the government, aware of the importance of these spaces. While Ryanair has been winning passengers in Spain, now he faces new fines. Some of the routes survived by the commercial agreements that Ryanair maintained with municipalities and other entities for advertising that acted as Covering line of the line. That has caused the complaint of, among others, The Mayor’s Office. Who is right? It remains to be seen. At the moment, the sanction is imposed but in Spain justice has proved both to the government and the company Despite judging the same fact: the possibility or not of Ryanair to charge for hand luggage. Until now, aerial regulations force airlines to let a lump pass that allows the “essential” to transfer. That, according to the government, cannot enter the brief measures that The company applies. Ryanair alleges otherwise And emphasize that there is no paper that proves the minimum size that the backpack has to have. The latest changes. Everything indicates that Europe is going to put on the side of Ryanair. The institutions are advancing in a new regulation to fly in which you want to stipulate a minimum measure for cabin luggage. This is slightly higher than that forced by Ryanair and The company has already made the changes to adapt to the regulations. It remains to be seen, to leave that new regulation ahead, the company would end up claiming Spain the money of the large fine with which it has punished it. This listing list shown can completely change if your claims get ahead.

We have detected the greatest fusion of black holes seen to date. It is a problem for our theoretical models

by

One of the enigmas that most intrigue astronomers is that of Black holes of intermediate size, those black holes halfway between the holes of stellar mass and the supermassions such as the one that dominates in the center of our galaxy. These are black holes with masses between 100 times that of our sun and those that multiply this star mass by millions. GW231123. A group of Ligo-Virgo-Kagra (LVK) collaboration researchers (LVK) has announced The detection of the greatest clash between two black holes registered to date. The discovery has occurred thanks to the gravitational waves generated by the impact, whose signal has been called GW231123 by those who detected it. November 2023. The name of the signal refers to the date on which it was observed, on November 23, 2023. The study of the detected waves led those responsible for the new study to estimate that the resulting black hole had a dough some 225 times higher than that of our sun. Until now the most massive had been “alone” 140 solar masses. It was in 2021, the GW190521 signal. Estimates indicate that the 2023 signal was the result of the collision between a black hole of 100 solar masses with one of 140 solar masses. That is, only one of the black holes was already as massive as that of the fruit of the largest shock detected so far. From this event not only highlights its magnitude, but also the fact that the speed of rotation of black holes was surprisingly high. A new enigma in heaven. All this planet an important unknown for the team. As they explain, the holes of such mass cannot be formed from the death of a star, at least based on what contemporary physical models say. The only way we know can be formed is through the fusion of smaller black holes. LVK. In 2015, the Ligo experiment made history detecting for the first time the clash of two black holes through the expansion of gravitational waves associated with such a violent event. This pioneering experiment has been company in Europe and Kagra for years (Kamioka gravitational wave detector) In Japan. Together they have already detected more than 300 clashes between black holes. The details of the study They have been presented In the 24th International Conference on General Relativity and Gravitation (GR24) and 16th Conference Edoardo Amaldi on gravitational waves, a joint conference held this week in Glasgow, Scotland. Not so easy to observe. The detection of GW231123 “pushed the limits of both gravitational wave detection technology and current theoretical models,” says the responsible team. Analyzing these types of events through gravitational waves is not easy, but knowing more about them can help us unravel some key mysteries of the cosmos. “Black holes seem to turn very quickly, almost to the limit of what is allowed by Einstein’s theory of relativity,” explained in a press release Charlie today, co -author of the study. “This makes the signal difficult to model and interpret. It is an excellent case study to push the development of our theoretical tools.” Looking for the midpoint. Theoretical tools that perhaps help us reveal the secrets of the elusive black sized black holes. Today we do not know very well how these holes are formed whose mere existence implies the certainty that we still do not know about our universe.

The countries with the greatest oil reserves, exposed in this graphic with a sad protagonist: Venezuela

by

Humanity is still tied to oil. Although the rise of renewable energies He pointed to one revolutionrecently we have seen that, when things get ugly and We need energy peaksone has to Pull fossil fuels again. The oil companies themselves who got into the renewable car They unchecked a few months agoand that is why it is interesting to know What countries have that oil. And it is something that is illustrated perfectly in this graph. The rich. Prepared by Visual Capitalist With data from the EIAin it the production is not shown, but the reserves. They are two very different things and will make sense immediately. Before that, Venezuela’s reserves are imposing, with 303,000 million certified barrels. Secondly, Saudi Arabia with 267,000 million and, in third place, an Iran in which oil has been the protagonist in recent weeks due to the confrontation with Israel. A lot of distance from Venezuela we have Canada, Iraq, Eau, Kuwait, Russia, the United States or Libya. And, of these last names, the two American countries are those that are separated in the graph because they are not part of the OPEC. OPEC+ and the monopoly. In 1960, five heavy pesos on that list (Venezuela, Iran, Kuwait, Saudi IRK and Rabia formed the organization of oil export countries, OPEC. Its objective was to coordinate and unify oil policies to maintain stable prices, ensure supply and, above all, protect your interests. Over time other countries were added, forming the well -known OPEC+ (which has its own internal cohesion problems. Together, member countries concentrate about 80% of global oil reserves, but although Venezuela has imposing reserves, its production does not go to par due to political blockages and limitations. At its peak, they produced three million barrels per day. Today they are the twenty -first producing country with 770,000 barrels per day, behind countries with much lower reserves. One of the wells that China is operating China wants to sign up for the list. At the top, the United States, Saudi Russia and Arabia lead the ranking with 8-12 million barrels per day, but although it does not appear in the graph, there is a country that we should take into account: China. Currently, the Asian giant is the Greater World Oil Importerbut in recent years it has increased significantly Its internal production. Thanks to pharaonic works that include some of the deepest wells carried out by humanityin March of this year they got a record of 4.6 million barrels per day. It was the highest point in the history of the country and, although inequality was very high between production and import, apart from continuing excavating they have been made with record reserves in recent years. It is calculated that They tell With more than 1,180 million stored barrels that would shield them, for a while, of any cutting in the supply. The United States, for example, also has a reserve to respond to crises and the sources vary, but the updated figures point to about 400 million barrels. Pure and hard strategy. Beyond the obvious importance of oil on the economy of a producing country, we have the Strategic Facet. As oil continues moving the worldhaving large reservations allows countries to exercise their influence on international politics. As? Coordinating production to influence prices and economyFor example. And we have also seen how oil has been a protagonist agent in armed conflicts. The invasion of Iraq, for example, or the war between Iran and Israel that, without affecting the flow of crude oil, already caused that The market will panic.
