Why use an antivirus on your computer Although current operating systems offer their own protection systems that serve to block most threats, cybercriminals are always one step ahead. It’s a constant grind, and by the time one threat is resolved, new ones are already being launched. Thus, new viruses, phishing and malware attacks, as well as zero-day exploits, appear every so often. Third-party antiviruses carry them companies specialized in cybersecurityand therefore its only job is to detect new threats and launch updates for its antivirus with which to protect you. Their reaction time for new threats is lower than that of the operating systems themselves, and that is why they are useful if you want the best security. This does not mean that the antivirus on your cell phone or computer is bad, but that it can be improved with the additional layer of security that these programs offer. The laboratories of antivirus companies are dedicated to monitoring the Internet in search of new threats, checking the data received from their users to detect them, and investigating them in their laboratories to obtain a solution as soon as possible. A modern antivirus not only detects and removes malware, but also protects you against fraudulent URLs, blocks exploits in real time, protects your browsing, monitors your email, and offers you tools against identity theft or malicious encryption of your computer in a Ransomware attack. Therefore, in summary, your operating system offers you basic protection for most threats, but if you want better protection you should use a specialized program. Whether you consider it necessary or not It depends on each of usthe data we keep on our computer and how much it can hurt us to lose it in the event that a virus attacks us.

Seek information about this before making a final decision. Extra features: There are antiviruses that offer extras in their prices such as a VPN, password managers, cloud copy systems, parental controls or identity protections.

Others will have more recurring offers, and others may seem more expensive but it will always be the same price. Consider the total price of the renovations and not just the promotions. Compatibility and support: Make sure you are going to pay for an antivirus that has applications for your desktop operating system but also for your mobile if you need it. Also offer customer service in your country. Ease of use: There will be some antivirus that are easier to use and simpler, and others that are more complex but perhaps also more configurable.

the alpha generation is here

Have you seen someone on social media shouting “six-seveeeeen” with their hands in the air and an inexplicable smile? Don’t worry: you’re not losing your mind or getting into the weird side of TikTok (well, maybe a little). It is the new meme that is sweeping the Alpha Generation, and it is repeated so many times that it seems like a collective invocation. Nobody knows what it means, and that’s the funny thing. But here we want to know its origin. If we follow the trail it takes us to December 2024, when the rapper Skrilla released the song “Doot Doot (6 7)”. According to The Wall Street Journalthe “6-7” of the track refers to Philadelphia’s 67th Street, where many of his friends grew up. But within weeks, the internet hijacked the number and stripped it of any context. The next protagonist was Taylen Kinney, a 17-year-old point guard in the Overtime Elite league. In a video with teammatesKinney rated a Starbucks drink by saying, “Like a six… six… six-seven,” while moving his hands as if weighing two options. That simple reaction —explains The New York Times— was uploaded to TikTok, and within a month it was a cultural symbol. Kinney gained over a million followers, launched his brand “Mr. 67” and up to a “6-7” canned water line. 12 years old. But the definitive explosion came with a 12-year-old boy, Maverick Trevillian, nicknamed “the 6-7 boy.” At a basketball tournament organized by content creators, he shouted the phrase with such enthusiasm that became an instant meme. “Kids say ‘6-7’ every second of every day,” admitted to The Washington Posta medium that interviewed him along with his parents. From there, the cry jumped from phones to real life: teachers suffer from it, parents prohibit it, and even South Park dedicated an episode to the phenomenon. And what does it mean? If you’re trying to look for a hidden meaning, stop doing it: there isn’t one. “6-7 is a joke without a punchline, a joke without logic”, explains CNN. It is the typical occurrence that spreads precisely because it makes no sense. “Nobody knows what it means and that’s the funny thing,” said an American professor to the same medium. For some, it is a kind of generational secret language. As linguist Gail Fairhurst points outusing the meme is a form of belonging: if you know when to say it, you are within the group; If not, you’re out. The absurd works as an emotional password. Euronews defines it forcefully: “It means nothing. Absolutely nothing.” Although some children use it to qualify things (“Taylor Swift’s new album is a 6-7“), the consensus is that its value is in its emptiness. It is, as Skrilla himself would say: “An energy without explanation.” And, of course, the adults are baffled. “Teachers avoid saying six or seven in class, it’s like throwing catnip at cats,” a Texan teacher joked in The Wall Street Journal. Alpha memes: the evolution of absurdity. Each generation had its way of confusing adults. Millennials invented digital sarcasm; Generation Z embraced the nihilistic irony of “Skibidi Toilet“. But Generation Alpha has gone further: its humor is defined by total incomprehensibility. The linguist Salvatore Attardo, quoted by The Washington Postmaintains that “the mechanisms of humor have not changed since Greece; what has changed is the format.” What were once comic novels are now ten-second videos or two shouted numbers. From Euronews They point out that this nonsense as a reaction to contemporary chaos: in an overwhelming world, shouting “6-7” is a form of joyful rebellion. There is no cynicism, no political message: just the joy of not having to explain anything. And, in a way, that fits with today’s digital zeitgeist. Memes have become “cultural glue” for a decade: from “Let’s calm down” to “Chill Guy”, each one reflects the psychology of its time. If the “Chill Guy” embodied zen calm In the face of burnout, “6-7” represents total surrender to fun chaos. Although it’s not the first time. In reality, shouting out random numbers has an illustrious history. The Washington Post compares “6-7” to the enigmatic “23 Skiddoo!”an expression that swept the United States between 1905 and 1906. Nobody knew what it meant, but everyone repeated it. More than a century later, the “Ok, Boomer” marked another generational boundary: a subtle (or not so subtle) way of saying “you wouldn’t understand.” The difference is that “6-7” doesn’t mean anything about anything. No criticism, no irony, no message. It is a shared void, a community joke. Generation Alpha didn’t invent the trend of adopting a random number as a motto. It only perfected the idea that meaninglessness can unite us. Adults react (and kill the meme). As always, the adults arrived late. Guardian I already warned: “As soon as the media talks about it, the meme is dead.” Some American schools have banned saying “6-7” in class. Other teachers, resigned, use it to neutralize it: “The best way to kill a meme is for adults to say it,” said a linguist. And while analysts classify it as an example of “brain rot”we can do another different reading. It is a linguistic game, a form of belonging as innocent as saying “ola k ase” more than ten years ago. In the words of comedian Josh Pray: “I’m trying to get our numbers back before I turn 67 and they yell at me in the street.” A legacy of meaninglessness. Perhaps in a few months “6-7” will disappear, replaced by another number (“41” and “93” are already circulating, according to Know Your Meme). But his brief reign says a lot about how younger people communicate: in fleeting, self-referential codes that are completely impenetrable to older people. Perhaps therein lies its hidden message: that there is no message. That the Alpha Generation, raised among algorithms and crises, reserves the right to play with language without looking for meaning. And that, in a world where everything is analyzed, explained and monetized, can be a … Read more

Although it may not seem like it, meritocracy does exist in Spain. At least among the millionaires

In Spain, the idea that millionaires are born rich by inheritance It is changing, or at least that is what the various data and analyzes say. Recent figures show that in Spain the number of millionaires has increased “self-made“, scratching space for those who They have inherited their fortune. However, as in so many aspects, the data can tell different realities. Millionaires in Spain according to UBS and Forbes. The report ‘Billionaire Ambitions Report 2024’ prepared by the Swiss bank UBS, reveals that 44% of billionaires in Spain have created their fortune from their own work or investments. However, this figure contrasts with the published data by Forbeswhich show that about 74% of the big millionaires in Spain are rich thanks to inheritances that they have received from their family, leaving only 26% of those who would have obtained it on their own merits. Rich or very very rich: that’s the difference. So, which data is correct, UBS or Forbes? The short answer is both, because the difference is in the type of millionaire analyzed and the sample size. Forbes focuses only on billionaires (with assets in the billions of euros), while UBS includes highest net worth millionairesbut not necessarily at the global peak. According to the study data According to Charles Schwab, it takes $2.3 million to be considered a rich person. But to be considered a UHNWI (Ultra High Net Worth Individuals) or people with a assets available to invest of more than 30 million dollars. Depending on where that threshold is placed, the percentages also change. Heirs and own fortune. If only those who have more than 30 million dollars to invest (the UHNWIs) are taken into account, the percentage of Spanish millionaires who have inherited their fortune drops to the 14% that UBS indicated. This percentage also coincides with that given by the study by Jonathan Wai and David Lincoln which examines the nature of fortunes around the world. According to the data from this study, in Spain 38.4% of millionaires have received an inheritance and have multiplied that money through investments or their own projects, creating a new fortune from a previous financial base, while 47.5% have managed to build their wealth without receiving a significant inheritance. These figures show that meritocracy among millionaires exists, but adds the nuance that, in many cases, this fortune is the result of a combination between inheritance and effort staff. Don’t call it meritocracy: call it environment. When creating a new fortune Not everything is reduced to inheriting money, but it also depends largely on the social environment and the opportunities offered by birth. in a wealthy family. Having access to contacts, preferred education, and financial support increases the chances of success, even for those considered “self-made.” According to a report According to the Social Observatory of the La Caixa Foundation, it takes four generations to rise from a situation of poverty to the middle class. The report ‘To Have and Have Not – How to Bridge the Gap in Opportunities’ prepared by the OECD, points out that the socioeconomic environment of parents contributes up to 75% to the definition of their children’s opportunities. That is to say, a young person born into a wealthy family has more opportunities and economic support to start projects—which may be a failure, but also a resounding success—that a young man with few resources. That family support must also be taken into consideration when labeling “self-made” fortunes. Although this does not detract from the merit.

Windows XP’s “FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8” was legendary. Windows 95 was even worse

Recently we knew the origin of the legendary Windows XP activation key. That famous set of digits (“FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8“) that many of us end up memorizing became a singular demonstration that attempts to protect software do not always go well. Microsoft knows a lot about this, because its first systems to protect its operating systems and applications were even worse. The rule of “Let it be divisible by 7”. Microsoft tried to protect illegal copies of Windows 95 with a system that varied depending on the type of license. That system, however, was really weak. One of the most common licenses was the “CD Key”, which asked us for a code made up of 10 characters and two segments: XXX: could be anything from 000 to 998, but with one curious exception: the three numbers could not be the same (111, 222, …). XXXXXXX: The second segment is where a simple algorithm came into action. For the number to be valid, it was enough that it was divisible by seven. Not only that: you could enter 0. Microsoft ended up prohibiting entering all zeros, but it didn’t matter: the rule of being divisible by 7 was still fulfilled. That made coming up with compliant combinations very easy. One of the most used CD Keys was 000-000007, but 111-1111111 was also widely used Office 97 used one more digit. Instead of 10 digits, Office used 11 in two segments. XXXX: could be anything from 0001 to 9991. There were no prohibited numbers but the fourth digit had to be the third + 1 or 2. If the result was greater than 9, it became 0 or 1. XXXXXX: the same requirement as the previous one, although at least in Office 97 it did not seem to be necessary for it to comply with being divisible by 7. Thus, two keys that could work were 0001-0000007 and 1112-1111111. Things got complicated (a little) with the OEM keys. If our computer arrived with Windows 95 preinstalled, it could be that instead of a CD Key what we had to enter was an OEM Key. These keys consisted of four segments: XXXXX: represented the date the key was printed. The first three digits could be anything between 001 and 366, and the last two were the year, which could range from 95 to 03. For example, a key with 19296 as the first segment means that it would have been printed on July 10, 1996. If you wanted maximum compatibility with Windows XP, it was ideal to use 02 as the last two digits. OEM: The second segment simply had those immutable letters. XXXXXXX: the third segment had to be divisible by 7, but with another small condition: the first digit had to always be zero. XXXXX: The last segment was completely random, and could be any number of the appropriate length. Thus, to comply with validity we had keys such as 00100-OEM-0000007-00000, but it was possible to use any other such as 06900-OEM-0694207-80085. How was all this revealed? You could figure out how Windows 95’s key system worked if you’d seen enough of them. However, what really allowed us to understand this entire algorithm was the leak of the Windows NT 4.0 code, which is in fact available at Archive.org. This allowed some users to reveal both on video as in detailed articles How was it possible to discover the “check_retail_key) function of Windows NT 4.0, which was part of the system’s setupx.dll file.

Justice has told them a couple of things

Convert a window into a door to have private access to the common patio, install the washing machine, place pots and a clothesline. This is how two owners acted of a building in Seville without having the authorization of the community of neighbors. The Provincial Court has confirmed that they must now reverse all the works and remove their belongings from the patio. Conflict. As you can read in the sentencethe lighthouse was a common space belonging to two buildings. One of them filed a lawsuit against these owners for opening a hole in the wall that faced the patio, allowing them to access directly from their home and use the area as if it were private, just as they explain from NewsWork. All of this without having requested or obtained the approval of the owners’ meeting. The defense. The reported neighbors alleged that there was discrimination, since another owner had maintained a similar door to the same patio for decades. They also argued that the neighbors at the time expressed indifference and that the lawsuit was motivated by poor personal relationships. However, none of these arguments succeeded. What the law says. The Provincial Court of Seville rejected the appeal and confirmed the First Instance ruling. Just like express From the middle, according to article 7.1 of the Horizontal Property Law, no owner can make alterations to common elements without express permission from the community. Opening a hole in the façade requires approval by board agreement, something that in this case was never requested. The problem of exclusive use. The court pointed out that he article 397 of the Civil Code establishes that no community member can use a common space in a way that excludes others or prevents their use. By installing a washing machine, pots, clothesline and other personal items, these owners were depriving the rest of the neighbors of shared use of the patio. Someone doing it is not enough. The fact that another neighbor has been granted that right does not automatically authorize the rest of the owners to do the same. The sentence discard the “comparative grievance” as a justification for repeating previous violations, especially when there is no community agreement to support it. In this way, the community would have acted within the legal framework. A recent use. The defendants were also unable to demonstrate that they had acquired rights through the passage of time. The acquisition of easements by prescription requires peaceful, public and continuous use for at least 20 years, according to the article 537 of the Civil Code. In this case, just as share the medium, the intervention was recent and without legitimation. Conviction. The two neighbors must close the door, replace the original window and remove all elements from the common patio: washing machine, flower pots, clothesline and any other object. In addition, they are obliged to repair the damage caused in the area and assume the full cost of the work to restore the previous state of the façade and the shared patio.

Maybe it’s time we stopped answering “maybe” to calendar invites

Science has just demonstrated something that we all intuited but no one wanted to admit: when you respond “maybe” to an invitation, You are not being polite. You are being selfish. A study published in Science Direct and brought by Causes and Chances explains that hosts prefer a firm “no” to an ambiguous “maybe.” The reason is simple: the “maybe” forces them to plan for two simultaneous scenarios: Should I reserve a table for five or six? Should I buy food for eight or nine? Do I leave time for questions from twelve people or eighteen? That uncertainty is not courtesy. It is a burden that we transfer to others. Those who answer “maybe” operate under a systematic illusion: They think they are showing interest, that their indecision is better than rejection. But the data shows the opposite: Hosts feel more respected with a “no” than with a “maybe.” There’s something telling here: we confuse keeping our options open with being thoughtful, when in fact we are exporting our own indecision as a problemoblivious ma. We transfer our problem (I’m afraid of sounding rude, I don’t want to have to choose yet) to the other (how the hell am I going to plan the event if there are 10 yeses and 24 maybes). The study identifies a classic case of motivated reasoning here: We answer “maybe” because it suits us (we reserve the freedom to decide later). And then we rationalize that selfish decision as if it were what the other person prefers. It is such a common self-deception that we don’t even notice it. We project our preferences over othersand thus we save ourselves the discomfort of recognizing that we are prioritizing our flexibility over your planning. The practical implication is clear: if you’re going to answer “maybe,” it better be because you really need time to figure something out, not because you want to wait to see if something better comes along. Not because it’s hard for you to say no. The “maybe” has a cost that is paid by whoever sends the invitation. The next time we get a calendar invitation, we should ask ourselves if we are being thoughtful or just covering our backs. The answer probably makes us uncomfortable.

The average price of Mb/s in each country in the world, arranged in a graph in which there is a unicorn: United Arab Emirates

Accessing the Internet is a necessity. In an increasingly connected world and in which we trust practically all aspects of our lives to online applicationshave a good coverage and speed It has become something essential. In fact, a server “blackout” like him recently lived with those from AWS demonstrates to what extent we depend on this connection. However, although the Internet is global, there is a huge digital divide. To the point that there are some who pay a cent per Mbps… and others exceed four euros for the same amount. The graph. With data from We Are Socialthe graph prepared by Visual Capitalist compare the price of megabit per secondor Mbps, in more than 60 countries in 2025. Before commenting on individual cases, because there are very striking ones, it must be said that the estimate is that the average price of Mbps worldwide is around 45 cents. The global average is also around 40 euros, but as we can see in the data, there are countries above and below that completely distort that average. And something important to understand is that the price of Internet responds to infrastructure and population density (it is expensive to bring broadband Internet to remote populations), but also to factors such as competition and tax policies. One question: United Arab Emirates. The United Arab Emirates perfectly exemplifies those last two points. It almost seems incredible, but the price of Mbps in the country exceeds four euros. Data from We Are Social puts it at $4.31 per Mb/s, almost double what is paid in the next most expensive country: Ghana with its $2.58 per Mb/s. On average, an Emirati pays between 100 and 140 dollars just to have Internet, and the big question is what is happening to make that happen. The answer? Politics and competition. In the UAE there are only two companies that provide the service, so this lack of real competition means that they do not have a need to lower the price. Do you want Internet? Well, take it or leave it. Plus, there is the political part. The State forces operators to transfer up to 30% of their profits to the country’s coffers, and it is something that directly affects the price of the final bill for the consumer. The speed not bad (an average of 300 Mbps), but it is evident that the price is prohibitive for many, potentially generating the aforementioned digital divide. The Romanian secret. In it opposite side On the spectrum we have the countries of Eastern Europe, specifically in a country whose flagship company we know well in Spain: Romania and DIGI. The average prices for fiber optics in the country are around 10 euros and the price of Mb/s is just 0.01 dollars. Russia and Poland are not far behind, and what has caused this is precisely the opposite of what is happening in the UAE. After the fall of communism, dozens of private operators They began to deploy decentralized fiber optic networks. Taking advantage of community wiring in cities and building blocks, the “last mile” problem was solved, allowing Internet to be offered to a large number of people with minimal costs. It is estimated that almost 90% of Romanian homes have high-speed Internet and DIGI has exported that “policy” outside its borders, offering the longed for 10 Gbps at the price of 1 Gbps in countries like Spain. Above the dollar. Commenting on each country is a complex process because there are multiple factors that come into play, but I find it almost more interesting to see which countries are whose Mbps exceeds the dollar. In fact, these countries perfectly exemplify everything that comes into play when it comes to offering a cheap connection: Swiss: The average price is just over two dollars per Mbps due to the dominance of a single operator and the country’s salary structure: high salaries and, therefore, high maintenance costs. Kenya: averages about $1.54 per Mbps due to its poor fiber infrastructure that makes the country depend to technologies like starlink or the google balloons. Now, the competition is increasing little by little. Morocco: its $1.16 is explained by uneven infrastructure and just three companies that dominate the market. Australia: At its $1.33 per Mbps, the tremendously dispersed geography comes into play, with rural areas very far from each other. Germany: It is the one that is around a dollar per Mb/s and is not the fastest connection in Europe, far from it. In fact, it is a paradoxical situation as it is a power in Europe while having a worse cost/speed ratio than its neighbors. Reason? A large operator that dominates the sector and an old infrastructure, with many areas in which copper continues to be the trend. The Spanish situation. Within our borders, Spain has a comfortable position. There is enough competition so that prices are affordable, with an average of about 10 cents per Mb/s and 1 Gbps packages that are around 30-40 euros per month, depending on the company. Unlimited data is not uncommon on smartphones either. There are many companies that compete in a controlled and regulated environment, with obligations such as sharing infrastructure, and all of this has caused Spain to be a benchmark in the fiber deploymenteven in rural areas.

a tunnel between Russia and Alaska

The United States and Russia are separated by the Bering Strait. Barely 80 kilometers of sea divide the two nations, but in the winter months, something curious happens: it is possible to go from the United States to Russia by walking on the waters. In the middle of the strait are the Diomedes Islands, and each one belongs to a country. When the sea freezes, the four kilometers between islands become a corridor what is illegal travel. Now, however, Russia and the United States are approaching positions to create a corridor between the two countries. A tunnel between Alaska and Chukotka in Russia. In short. US President Donald Trump has emerged as a key actor in two of the most important and media conflicts of recent times: the Israeli intervention in Palestine and the war between Russia and Ukraine. Whether it was a campaign to get the long-awaited Nobel Peace Prize or not, the truth is that Trump has convertedand has turned the United States, in a considerable entity in both conflicts. Maintains constant calls with Zelensky and Putinand after one with the Russian president, the idea of ​​physically connecting the United States and Russia has returned. After one of those calls, Kirill Dmitriev, director of the Russian Direct Investment Fund (RDIF) and the Kremlin’s special representative for international economic cooperation, launched the proposal in Twitter X: a 112-kilometer railway tunnel between both countries, in the Bering Strait and under the Diomedes. Dmitriev’s decision was not spontaneous and, according to him, the RDIF has been carrying out a feasibility study of the project for months based on previous experience connecting Russia and China over the Amur River. 150 years of projects. The idea is not new either. In fact, Dmitriev himself alluded days before ‘World Peace Bridge‘that was created in the Cold warduring the Kennedy-Khrushchev era, but the truth is that plans to connect both territories have been on the table since the 19th century. In 1890, an American governor proposed a railroad that would link the world and pass through the Bering Strait. Two years later, the designer of the golden gate He presented his idea, although the Russians rejected it. In 1904, American railroad entrepreneurs they returned to the charge with the idea, the tsar Nicholas II gave the go-ahead and then came the Russian Revolution and the World War I. He later explored the possibility of the connection again, but 150 years later, Russia and the United States still do not have their tunnel. The letter from “the boring company”. What could be the key now to undertake the works? Beyond the geopolitical card, the costs. In his proposal, Dmitriev outlined some of the results of that feasibility plan, stating that a tunnel in the Bering Strait would cost more than $65 billion if traditional methods are used, but (and here comes the “but”), another entity could lower the total cost of the project to less than $8 billion. Who? Elon Musk and his company The Boring Companionand. The Russian representative claims that the technology from Musk’s tunneling company (which built the The Loop tunnel in Las Vegasin addition to starring in several controversies for their projects) would allow not only to turn the project into reality with a low budget, but to do so in less than eight years. frozen enemy. The problem, if all parties agree, is that the soil in Las Vegas is not the same as that in the Bering Strait. At 112 kilometers in length, the tunnel would be twice as long as the Eurotunnel between France and England and, furthermore, it would have to be excavated in very complex terrain. To begin with, the region is located in the Pacific Ring of Firean area with moderate seismic activity, but where earthquakes of magnitude seven can occur. In addition, it would have to be excavated 45 meters below the seabed to protect from currents and, most importantly, the entrances to the tunnel would be in permanently frozen ground. If everything remained unchanged, it wouldn’t be much of a problem, but Alaska has experienced a increase in average temperature during recent yearssomething that is expected to continue due to climate change, and melting ice would complicate maintenance of these parts of the tunnel. In fact, it’s already happened on the Trans-Alaska pipeline. We will see if this project comes to fruition or if it ends up on the list of “we should make a tunnel”, but the truth is that there are too many against it, starting with issues of national security, geopolitics, the terrain itself, the extreme geological conditions and even the train connections that would have to be made through Alaska and Russia for the tunnel to be of any use.

The origin of the oceans on Earth has always been somewhat mysterious. Now we are clearer how it happened

A team of scientists, analyzing the tiny and invaluable samples of the asteroid Ryugu brought to Earth by the Hayabusa2 missionhas made a discovery that shakes our understanding of water in the early solar system. The discovery, published in the prestigious magazine Naturereveals that liquid water flowed in Ryugu’s progenitor body more than a billion years after its formation. Something that changes our paradigms. Contradiction. This new discovery contradicts the belief that water activity on asteroids It was a phenomenon exclusive to the first moments of the history of our solar system. And most importantly, it could force us to recalculate how much water these bodies brought to a young Earth. Many doubts. The story of how our planet became an aquatic world still has gaps. One of the most accepted theories is that carbonaceous asteroidsformed from ice and dust in the confines of the Solar Systemacted as a cosmic “water delivery” service for the inner planets. JAXA’s Hayabusa2 mission has provided us with a unique opportunity to study this process by bringing back 5.4 grams of pure material from the asteroid Ryugu. And this is very important. While meteorites that fall to Earth are altered by contact with the atmosphere and environment, the Ryugu samples are a near-perfect time capsule. This is because a perfect record of water activity is preserved within it, proof that fluids moved through its rocks sooner than could be expected. This is something fundamental that changes the way we think about where the water in asteroids comes from and ends up on our planets. Isotopic clock. To reach this conclusion, the team turned to a “radiometric dating“based on isotopes: the radioactive decay of Lutetium-176 into Hafnium-176. Something that can be similar to the ‘Carbon-14’ test that is better known. In an object as old as Ryugu’s father, you would expect the proportion of these elements to follow a predictable line, known as isochronewhich dates back to 4,565 million years ago. But Ryugu’s data did not fit these models. The samples deviated from that ‘reference’ line showing an excess of hafnium (or a deficiency of lutetium). In order to understand why, it was first ruled out that it was due to accelerated disintegration or the effects of cosmic radiation. This made the conclusion point differently than that, at some point, a liquid ‘washed’ and took away some of the lutetium from the asteroid’s rocks. The reasons. The event that triggered this late flow of water was, most likely, a violent impact. While the first aqueous activity, which occurred in the first seven million years of the solar system, was driven by heat from the decay of radioactive elements, this second event was different. Specifically, we are talking about an impact on the body of Ryugu’s ‘father’ that would have generated enough heat to melt the ice that had remained frozen inside for eons, and at the same time, would have created fractures in the rock that emerged as channels for liquid water to flow. On the Primitive Earth. If asteroids like Ryugu’s father were able to retain not only hydrated minerals but also large amounts of water ice for more than a billion years, their potential to ‘water’ other planets is much greater than expected. Current models of the formation of terrestrial planets could be underestimating the amount of water contributed by these bodies. According to this study, Ryugu-like planetesimals could have entered two to three times more water into Earth than is commonly estimated. This would have direct implications on our understanding of the origin of the oceans, the atmosphere and in general the conditions that made it possible for us all to be living here.
