The CAF equilibrium set and its light harmony in Jerusalem

by

The “great Spanish rail giant.” That is the denomination that is usually used to talk about construction and railway assistant. CAF, as this internationally recognized trains and rail supplier is popularly known. A Spanish company, from Guipozcoa, who is reaping huge contracts outside our borders. And that is also in the international view. CAF. It is one of those companies that sounds to us its logo and its acronym. You know you’ve seen it but you may not be very clear where or in which sector you can place it. It is not so weird, do not worry, although CAF is among the 200 largest Spanish companies. To get an idea of ​​its size, In 2024 he billed 4,200 million euros and generated more than 100 million euros of benefit. In Euskadi it has some 3,000 employees But it has more than 16,000 people hired throughout the world, since the bulk of its business is in Europe (58%) but also has projects in America and Asia-Pacific. Israel. It is precisely one of his projects abroad that is generating great headaches to the company. The company has been working with the Israeli Shapir to build and expand the red and green lines of the Light Jerusalem Rail. The project is not any nonsense. It is valued at 1.8 billion euros of which CAF should pocket 500 million if you deliver its part in a timely manner. In addition, it would manage 50% of exploitation of extension over a period between 15 and 25 years. Settlements. For CAF, being immersed in a project delivered by Israel already should be a problem, taking into account the genocide that is being carried out in the Gaza Strip. But, as if that were not enough, we talk about building 50 stations along 27 kilometers of new roads … in illegal settlements. On this map It is observed how Israel is expanding both lines to unite the illegal settlements of Jerusalem is already built with those of west Jerusalem. The Palestine Liberation Organization (OP) assures That the final intention of this type of infrastructure is to create permanent links between these spaces to hinder the reversal of its entity and its return to Palestine. International pressure. This position is not only defended by the OLP. The Special Rapporteur before the United Nations Human Rights Council published the report From the economy of occupation to the economy of genocide. In it he pointed to CAF as one of the companies that does business with illegal Israeli occupations. Amnesty International also asked To governments that take into account which companies under their umbrella are taking advantage of this situation. And pointed to CAF directly: “The company has only ignored the different resolutions of the United Nations Security Council, the European Union and the International Court of Justice that Israeli settlements consider illegal in occupied Palestinian territory, as well as the fact that the United Nations Human Rights Council itself declared illegal the project of this tram in 2016 and 2017 stating that ‘clearly violates international law and relevant resolutions of UN “ What does Caf say. The last point they point out from Amnesty International has a lot of relevance. The company indicated in its sustainability reports that “the Light Rail project is in territories that are subject to political controversy (…) No violation of human rights derived from the participation of the CAF group has been detected in any project.” In addition, CAF has also published Recently a document in which your role in the project, ensuring the following: “Beyond compliance with the applicable regulatory framework, CAF is firmly committed to business ethics and respect for human rights in all its operations, including the value chain, based on the highest standards of responsibility and transparency. For this, CAF has a series of norms, procedures and systems, adopted to the highest level, which make up a complete compliance system, application to the entire group, as well as the third The purpose of preventing and acting against any behavior that could be contrary to ethics, the law or the internal normative system of CAF. And emphasize that the project was awarded in 2019. 2019. The Spanish company defends itself by ensuring that this project was awarded in 2019 by omitting any reference to a previous date. They point out that the approval was given before Hamas to Israel’s attack and the subsequent invasion of the Gaza Strip. But what is overlooked, as they explain in Amnesty International, is that the project had already declared illegal by the United Nations Human Rights Council in 2016 and 2017. In fact, in fact, in fact, French company Alstom ended up coming out of the same Shortly before the entry of CAF after the pressures received although, yes, at no time were political reasons alleged since the company maintained a project in the Israeli city of Tel Aviv. Too much money? Indicated by entities such as the United Nations Human Rights Council or Amnesty International, CAF is in the spotlight both inside and Out of our borders. In fact, his participation in the Israeli project was one of the alleged reasons to try to prevent the Spanish company from being done with The so -called “Century Contract”which could report up to 3,400 million euros for supplying SNCB trains (the Belgian Renfe). Within our borders, the debate has also reached institutions. From the PNV they ensure that CAF is being pointed out by “responsibilities that do not correspond to it” and that terminating the contract (as they ask from the Elkarrekin we can) “could mean the closure of the company or take it out”, in words collected by The mail. Other companies. As we said, the Israeli project of this lightwail to connect illegal settlements has already caused the exit of Alstom before 2019 but, derived from the genocide that Israel is carrying out in the Gaza Strip, some other Spanish companies have also stopped working for that state.

We always believed that the light guns fired invisible rays, but the reality is the opposite: it was the TV that shot

by

Recognize it: if you are old enough to have played withA Light GunFor a while you thought that this gadget worked by firing rays of invisible light that television detected. Was it the position of the gun? The distance? Did the glass of the screen really knew when the goal was in front? Actually the solution was much simpler and ingenious. The light ray is in reverse: the gun is the receiver. Guns of what. First, let’s remember the history of the device: the light guns in video games began to appear in the thirties in mechanical arcades and evolved towards electronic video games in the 1970s and 1980s. Nintendo already experimented with early versions with its video shooting series for famicom in 1984, whose gun was not futuristic, but it seemed like a western revolver With the theme of the game. Nintendo arrives. The device of this most popular type was Nintendo Zapper for Nespossibly because he was accompanied by one of the most iconic games of the genre, ‘Duck hunt’. The Zapper was already tumbos since 1984 with the version for Famicom, but in 1985 it became the Zapper of NES and left in the United States with the science fiction design we know, automatically becoming a pop icon. In 1988 it was redesigned with bright colors to resemble even less to a real weapon and comply with the legislation. There were up to 17 official games for Zapper. In Xataka This genius has transformed the ZNA Zapper is an incredible laser ray gun But … how did it work? Actually the Zapper and the rest of the light guns of the time were not emitters, but light receptors. The process that followed to work was: when the player clenched a trigger, the screen turned black during a Frame. In the following, the objects to which they have to become white blocks, and the rest remains black. The human eye can barely distinguish this pair of Frames Inside the gun was a light sensor that detected if the area to which it was aimed had changed to Blanco. The game determined what objective had been “shot” according to the time in which this white block appeared, since each white objective was sequentially shown in a different frame. And of course, if the sensor detected the white light inside the expected interval, the shot was counted as a success. Only for old people. The ingenious method only worked on CRT screens, as technology depended completely on the speed and characteristics (on the shortcomings, let’s go) on the soda speed of the cathodic tube. On LCD screens, plasmas and other modernities, the delay changes, and so does the soda technology. What makes ancient games “rare” on modern televisions is also what prevents the gun sensor from correctly capturing the light and location of whites. {“Videid”: “X9HMC3A”, “Autoplay”: False, “Title”: “Nes Mini, Review and Spanish analysis”, “Tag”: “”, “Duration”: “250”} More guns. Then, especially in the field of recreational, more sophisticated guns arrived, such as ‘Operation Wolf’, which was actually a command that determined where it pointed according to the position of the gun, fixed in the machine of the machine (a method as ingenious as that of the Zapper, playing with what the player who is happening is believed). And then they arrived, in fact they do in machines that remain in operation, increasingly sophisticated systems, and that use infrared sensors or cameras to determine where the player points out. But the adorable imagination and naivety of the Zapper give him a unique personality. In Xataka | The Nintendo PlayStation exists: this is the history of the hybrid console that never reached the market (Function () {Window._js_modules = Window._js_modules || {}; var headelement = document.getelegsbytagname (‘head’) (0); if (_js_modules.instagram) {var instagramscript = Document.Createlement (‘script’); }}) (); – The news We always believed that the light guns fired invisible rays, but the reality is the opposite: it was the TV that shot It was originally posted in Xataka by John Tones .

They have burned 3.3 billion euros in developments that will never see the light

by

There are times that it is better to stop, recapitulate and, in the worst case, throw all the work in the trash. Because there are occasions in which it is better to throw the work in the trash than to move forward and continue trying into a project condemned to failure. That is what should be completed within Stellantis last year. And at the same conclusion this year has been reached. The result: 3,300 million euros lost in developments that will never see the light. In the trash. A few weeks ago, Stellantis published the results of his first half of 2025. The most striking figure was, without any doubt, The loss of 2.3 billion euros. A figure that is still much more striking if we take into account that last year, in the same period, a benefit of 5,647 million was thrown. The figure is explained by the tariffs that the company has had to face in the United States and for a descent in sales. Billing has fallen more than 12%, explained by a 6% sales fall in Europe (with some cars to review, such as Citroën C3) but, above all, 25% in the United States where they had a huge accumulated car stock In the dealers. But, above all, it is explained by money that has gone, directly, in the trash. Hydrogen. With the Presentation of the results The Cancellation of plans of Stellantis related to hydrogen. In its results account, losses of 733 million euros were attributed to the performance of this item in the first half of 2025. That figure was built with investments in Symbioa joint company with Michelin and Forvia for the production of hydrogen -moved vans. The production plant took more than 300 million euros that have not finished anywhere. However, it is estimated that stellantis losses directly related to hydrogen investments have been much higher and They reach about 1.8 billion euros. Keep in mind that Stellantis mounted, for example, a program for convert electric vans in hydrogen versions. Maserati. But hydrogen, which seemed like a future investment to take positions, seems almost the least of the problems when it is observed what is past with the Italian luxury vehicles. The Maserati MC20 is barely being sold and The company has canceled the plans To develop a completely electric version. The result is that in the first half of 2025 they have lost 552 million euros. But the problem is another. The problem is in 2024 when 1.5 billion euros went to drain. China is not the way. The big black point is that in 2024 Stellantis had the production of Electrical versions of the Maserati Quattroporte and Levant. The idea was to sell those cars, mainly, in China where the electric car is triumphing but the process was paralyzed at the last minute. The result is seen in your results account: 1.5 billion euros lost in the development of these cars. Before the Bad results of foreign companies In China, someone decided that it was better to brake and assume losses before the result was even worse than reflected. The intention was that these electrical versions They will occur in Mirafiori (Turin) So investments in personnel and machinery were already made. At least, we had to try to patch the matter. The last piece of dominoes. That obligation to do “something” with the Mirafiori plant was taken advantage of by Stellantis to try to boost the sales of Fiat 500. The electrical version has been added to modify the vehicle’s platform since the car was born as a purely electric vehicle. This last money is not explicitly reflected in Stellantis accounts but it is unquestionable that it has had to assume another stone on the road although it has been awarded to the rest of the investment items since, unlike cars such as Peugeot 3008 (born to house all kinds of technologies)the Fiat 500E was born as a car without combustion versions on the horizon. This last expense, in fact, seems to have been enough for Stellantis does not make the same mistake with the Peugeot 208 And think, from the beginning, to set up the car on a multienergy platform and, in this way, not have to turn back in the project. Even if he had not been born prior loss of 1,500 million euros with Maserati.

What is a light year and why it is impossible to travel in less than a year, according to Einstein’s relativity

by

Among all the rules that govern the universe, one of the most iconic and at the same time difficult to understand is the universal speed limit. The speed of light is not only an unwavering constant: it is the link between matter and energy, as Albert Einstein described with the most famous formula of science: E = Mc². Can Asom to the foundations of our own existencebut not travel to more than “C”. Only light can travel a light year in a year. Let’s define constants: the speed of light The speed of light is the key piece in Einstein’s equation. That “C” is not only a number, but the conversion factor that unites the concepts of mass (m) and energy (e). It is a constant that represents the speed of light in a vacuum, but also the speed limit for the spread of any type of information, signal or material particle in the universe. If you think very strong, it is the limit of causality itself: an effect cannot occur before its cause, spreading at the maximum “C” speed, can reach it. This speed is the same for any observer in the universe, regardless of their own state of movement. If you travel in a hypothetical 99% spacecraft of the speed of light and light a flashlight, the light of that flashlight will move away from you exactly at the speed of light, not to a fraction of it. It is one of the universal constants of physics. And the observations of the cosmic microwave background, The remaining light of the Big BangThey confirm that it has not changed measurable in more than 13.8 billion years. What speed is light, then? Although it sounds strange, the speed of light in a vacuum has an exact and defined value: 299,792,458 meters per second. To put it in more earthly figures, it is equivalent to almost one billion kilometers per hour. A photon of light would go around the earth’s Ecuador about 7.5 times in a single second. It is, according to Albert Einstein’s special relativity theory, the definitive and unwavering speed limit of the universe. An epic about measuring the above Calculating the speed of light has been one of the great sagas of science. After the philosophical debates of ancient Greece and an ingenious but failed attempt from Galileo using lamps between distant hills, the first estimate came in 1676. Observing the eclipses of ío, one of Jupiter’s moons, the Danish astronomer Ole Rømer noticed that they had a different duration According to the time of the year. He deduced that it was due to the additional time that the light took to cross the orbit of the earth when our planet moved away from Jupiter. Rømer estimated the speed of light in 220,000 km/s, a surprisingly close figure for the time. Half a century later, in 1728, the English physicist James Bradley He refined this measure using a different method: the aberration of stellar light. He noted that the apparent position of the stars changed slightly due to the speed of the earth in their orbit. Something similar to how rain seems to fall at angle when we run. From this effect, it calculated a speed of 301,000 km/s, a value with an error of just 1%. Michelson’s experiment. Image | Popular Science (1930) It was not until 1887 that scientists discovered the most surprising aspect of the speed of light. Albert Michelson and Edward Morley tried to detect the “luminous ether”, an invisible half assumption that, according to the belief of the time, filled the space to allow the propagation of light. With Your experiment They hoped to measure a difference in the speed of light depending on whether it moved in favor or against the “ether wind” created by the movement of the earth. However, they found no variation at all. Sometimes, scientific progress does not come from finding what is sought, but of accepting the evidence that hits old certainty. This was how this failure It became one of the most important results in the history of physics. He showed that the speed of light was constant regardless of the observer’s movement, knocking down the ether theory and laying the empirical bases for the revolution that Einstein would unleash later. What is a light year and what is used for Since 1983, the speed of light is no longer something that scientists try to measure with increasing precision. Its value was set with such accuracy which is now the meter itself that is defined according to the light. One meter is “the length of the path traveled by light in a vacuum during a time interval of 1/299792458 seconds.” This change hides a deep truth: the constancy of the speed of light is a more fundamental property of our universe than our own units of measure. We no longer use meters to measure the speed of light, we use the speed of light to define the subway. And this is how one of the largest units of measure we use is born, and that has been crucial to understand the immense scales of the universe. Although your name includes the word “year”, a light year is not a measure of time, but of distance. In a nutshell, a light year is the distance that a ray of light travels in a vacuum during the course of a terrestrial year. That is, in 365 days. Given the incredible speed at which the light travels, it is an astronomical distance, of approximately 9.5 billion kilometers. We use the light years because the distances in space are so huge that measuring them in kilometers would be totally impractical. For example, The exoplanet closest to EarthNext Centauri B, is about 4.2 light years away. In kilometers, that figure would be almost 40 billion, a much more difficult number to handle and contextualize.

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.

The evolution of income is being remarkablewithout a doubt, but both her and others – and here Anthropic is another good example – something serious happens to them: that they continue to spend more than they win. 12,000 million for OpenAi in 2025. As indicated In The Informationa new estimate that Openai’s “annualized” revenues will be 12,000 million dollars in 2025. The figure is a projection, but it is significant taking into account that in 2024 the estimated revenues were according to various sources of 3.7 billion dollars, although In Reuters They talked about the fact that they had actually reached 5.5 billion dollars. And 4,000 for Anthropic. The same media also recently indicated how the estimate in the case of one of its great rivals, Anthropic, has also risen and now It is 4,000 million dollars. Just two months ago that figure had already been checked and was 3,000 million, which means one thing: both are growing in number of subscribers. 700 million “Chatgpteros”. Another of the data to which the information article points out refers to the number of weekly active users. According to their data, 700 million people use chatgpt at some point in the week, which marks a unique milestone for the company. It is true that the vast majority of them are users of the free version, but that base is what allows part of those who use the service for free They end up pointing out to any of the chatgpt subscription plans. Income growth is being unusual in OpenAi and Anthropic, but both companies are spending absolute fortunes to end up being profitable. Source: Reddit. It will win 12,000 million, how much will it spend? In Reuters indicate that the internal estimates of the company also point to higher expenses. According to those projections, OpenAI will spend 8,000 million dollars, but that figure is dentra on direct operational expenses. There are many more associated expenses – investments, infrastructure, other financial obligations – and that makes OpenAi not profitable for now. We do not have estimated spending data for Anthropic, but it has an identical problem: Spend more than you earn. Spectacular, but. Although this growth in income is certainly extraordinary, it must be taken into account that to achieve this, these companies carry “Burning money” for years. The investment rounds that Anthropic and especially OpenAi have captured have allowed them to have a lot of room for maneuver to lose huge amounts of money without that at the moment that worries too much. And they will continue to spend as possess. Especially in the case of Openai, which thanks to SoftBank support It has great plans that will make it necessary to spend true fortunes. They have done it to Buy the Jony Ive design study for 6,500 million dollars, but above all they will do it with the project Stargatewhich still seems like very difficult to complete. But no profitability until 2029. Those responsible for OpenAi do not seem too worried, and we knew what the company’s financial road map was known weeks. They will continue losing money until 2029when supposedly – all is a free estimate, not a promise – will earn 100,000 million dollars. It will be then when the company will begin to be really profitable, but again, All this is a promise (or maybe a hope). It could not perfectly be fulfilled … and even ending up falling short.

WhatsApp finally has a quick and light application in Windows. Joy will last little

by

Meta launched WhatsApp for Windows and Macos In 2016. Since then, until 2022, the company had A slow and very little efficient customerfor a single reason: it was not a native application, but a web container based on WhatsApp Web, which implied slowness and enormous consumption of RAM. Better changes, changes worse. In 2022, WhatsApp on desktop made an praise leap forward, launching native messaging customers on both platforms and discarding the previous technology. According to Our own teststhe use of RAM in Windows went from 500 MB to 100 MB. The use of CPU making scroll, from 60 % to 20 %. Three years later, one step back, according to Windows Latest: WhatsApp beta (downloadable here) It is no longer native, it is a web container again that camouflages a browser. WhatsApp tricks and tips to hide you to the fullest and maintain your privacy Bad news. According to Windows Latest observations, made by analyzing the WhatsApp Beta processes in Windows Task Manager, Meta is using WebView2a technology that allows using the Microsoft engine within applications. Your own version of Framework Electrona standard in the industry. The bad news for the user in front of the application has nothing to do with using WebView2 in particular, but with abandoning the previous approach. This inefficient will be the new WhatsApp in Windows.Every time we open the new version, the application will have to load the web version internally, and in the background, an instance of the Microsoft Edge browser, on which Webview2 operates. Just as it happened with the version they developed from 2016 to 2022. It is very inefficient with respect to an application that uses Native Windows development platforms, such as UWP (Winui). In the absence of being able to prove it, Windows Delast tests demonstrate the step back, and are related to those made in Xataka in 2022. The new version of WhatsApp Web consumes 30% more of RAM than the version available until today in the Windows application store. It is a developing version that can be optimized more, but leaving the native approach has inevitable negative consequences. In Reddit Han accomplished that the new client consumes up to 1 GB of RAM. Goal explains why a native application is more efficient. When they launched the current client, goal created a website in which they explain the Benefits of a native application very clearly: “They provide greater performance and reliability, more ways of collaborating and functions that improve your productivity” “They are designed and optimized for your computer operating system” “They offer greater reliability and speed” Why use web apps instead of native. Being so clear the advantages of a native development, and even being defended by goal, why go back? The industry resorts to web -based applications for a very simple reason: unify developments and guarantee functions and compatibility parity between different operating systems. If a company builds a single website, you can easily adapt it to Windows, Macos, Windows, Linux and Android, as well as offer it in browsers. Optimization is sacrificed, but the deadlines are expedited and the size of the equipment required to move forward and maintain a project is reduced. Mark Zuckerberg himself said that IOS’s old Facebook app was bad because it was based on html. They went to native development and everything improved. The same In Android.

Some astronomers analyzed the “Big Bang sound.” Now they believe that the Earth is in a vacuum of 2,000 million light years

by

Cosmology has a huge problem. It is known as hubble tension and suggests that the nearby universe is expanding faster than the distant and primitive universe He is telling us. Something does not fit. Now, a disturbing study offers a solution. The big problem of cosmology. Hubble tension is One of the biggest headaches of modern physics. On the one hand, we have the measurements of the cosmic microwave background (CMB), the oldest light in the universe. When applying the standard cosmological model (LBDACDM), these observations show a 67.4 km/s/mpc hubble constant. On the other hand, when The expansion of the universe is measured Using nearby objects such as standard candles (a type of supernova), a significantly higher value is obtained: about 73 km/s/mpc. This difference, that the most recent data places in a tension of more than 5Sigma (a level that in particle physics is considered a discovery), refuses to disappear. A disturbing explanation. A new study Prepublished in Arxiv proposes a solution as elegant as depressing. That the discrepancy is not in our measurements, but in our location. According to Indranil Cosmologists Banik and Vasileios Kalaitzidis, we could be living in the center of a gigantic cosmic vacuum, a “bubble” of 2,000 million light years in diameter with a density 20% lower than the universal average. The test, they affirm, It is in the “Big Bang sound”. A local vacuum. The idea of the local vacuum is not new: it is known as the empty KBC (Keenan-Barger-Cowie, in honor of the astronomers who proposed the idea based on the galaxies count). If our galaxy, the Milky Way, were in a region with less matter than normal, the severity of the surrounding, densest areas, would “throw away” out. This effect, added to the general expansion of the universe, would cause nearby galaxies to move away from us faster than normal. “This would give the appearance of a faster local expansion rate,” explains Indranil Banik, of the New Research. The Hubble tension problem would thus become a local phenomenon, without the need to revolutionize the entire cosmological model. The sound of the Big Bang as proof. What the new study of Banik and Kalaitzidis contributes is a much more fundamental test based on barionic acoustic oscillations. Although we call them “the sound of the Big Bang”, they are not sound waves that we can hear. They are the traces that left the pressure waves that spread through the superdense plasma of the primitive universe. These waves were “frozen” about 380,000 years after the Big Bang and created A characteristic pattern in the distribution of matter. This pattern works as a cosmic rule of about 500 million light years in length, which astronomers use to measure the expansion of the universe to different eras. The results. The team analyzed 20 years of measurements and compared them with two scenarios: on the one hand, the homogeneous standard model, without emptiness; and on the other, the model that includes the empty KBC. The results, presented at the National Astronomy Meeting 2025 of the Astronomical Society Royal, are blunt. According to the statistical analysis of the study, the model with a local vacuum conforms to the data in a spectacularly better way. While the standard model has a 3.3sigma voltage with observations, vacuum models reduce it to only 1.1sigma –1.4sigma. Calmly. The researchers consider “demonstrated” that A vacuum model is about 100 million times more likely than a model without emptiness. However, it is a preliminary study, which has not yet gone through the pairs review. Previous studies set very strict limits to the existence of such an influential vacuum, concluding that it is not enough to explain the entire Hubble tension. They also propose early dark energy as a solution. But Banik’s work offers one of the strongest evidence to date that the Earth could be in a very lonely region of the universe.
