We have solved the problem of space junk by burning it. A SpaceX lithium trail just proved to be a terrible idea

by

For decades, the aerospace industry has had a consensus solution to the problem of space junk: burn it. A fairly simple phenomenon that is based on the satellite reentry when it ends its useful life in the atmosphere so that it begins to suffer friction and completely disintegrates. But the reality is that we are facing a huge problemsince physics reminds us that matter is neither created nor destroyed. We have captured him. Science is realizing that we are not removing space junk, we are just vaporizing it into metallic aerosols that are changing the chemistry of our own sky. And the definitive clue to this problem was found on the night of February 19, 2025where a team of German researchers pointed a laser into the sky over Kühlungsborn. What they detected in this case at about 100 kilometers altitude, in the thermosphere, was something that should not be there, since there were large amounts of lithium. And it wasn’t there for no reason, since it just coincided hours before with the re-entry of a SpaceX Falcon 9 rocket which had disintegrated over the Atlantic between Ireland and the United Kingdom. Something new. The signal measured in this case was not very subtle, since was 10 times bigger to the usual concentration in that region, and this finding was collected in an article because it marks a great milestone: it is the first time that the metallic contamination released from a specific piece of space junk at the exact moment of burning has been observed “live” and from Earth. The metallic iceberg. The incident with this Falcon is not something isolated in our society, but is a symptom of the structural change we are experiencing. In 2023, a team of researchers already used different devices to be able analyze more than 50,000 aerosol particles in the stratospherewhich is the layer where our ozone layer resides, at about 15-30 km altitude. What did they see? Historically, the metals found in the stratosphere came from meteorites that entered our planet. But today it is estimated that 210 tons of aluminum per year in the atmosphere comes from the disintegration of satellites and rockets, compared to the 20 tons per year that vaporize naturally from meteors. But lithium is not the only metal in the atmosphere of our planet, since scientists have detected more than twenty elements, among which aluminum, copper, lead or silver stand out… This is something that does not fit with the normal composition of meteorites, but it does coincide with the materials that different aerospace companies use to create their rockets and satellites. There is no planning. The pace of launches has skyrocketed in recent years, and if today we are close to 10,000 objects orbiting the Earth, we have to know that only Starlink aspires to have more than 40,000 satellites in Earth orbit low. But the problem is that the useful life of these devices is short, so their inevitable fate is to end up vaporized over our heads. Its effects. Science here is quite clear that the effects of filling the stratosphere with these metals are currently unknown. But the projections suggest that we should not be calm because elements such as aluminum and copper are important catabolizers that can affect the delicate ozone layer. In addition to this, metallic particles can act as special condensation nuclei, altering the microphysics of polar stratospheric clouds. And if that were not enough, adding anthropogenic material to sulfuric acid aerosols changes their size and ability to scatter sunlight. Ironically, we are altering the reflectivity of the stratosphere, the same layer that some scientists want to use for climate geoengineering, without knowing what the consequences will be. The planetary limit. The models here suggest that, if the planned megaconstellations materialize, the fraction of stratospheric particles contaminated with aluminum from satellites will rise from the current 10% to around 50%. In other words, the load of metals in the stratosphere could grow by around 40% compared to natural levels. Here for years space agencies have assumed that disintegrating satellites was a completely harmless and clean practice. The example of the Falcon 9, which has validated the warnings of the scientific community, shows us that the Earth’s orbit and our atmosphere make up a connected ecosystem. In this way, launching tens of thousands of objects into space and then burning them on our own roof may be a solution to keep space clean, but we are dirtying the sky in return.

A few years ago, manufacturers fought for the most powerful mobile phone. Now they fight so they don’t go out burning

by

Not too long ago, Samsung and Apple were trying to convince us of something: the titanium It was the best material for a high-end mobile phone. As a user of both the latest Galaxy and the previous iPhone, I have to say that I agreed: we were never looking at mobile phones more resistant to shockschips and all kinds of everyday accidents. With the iPhone 17 ProApple backtracked to return to aluminum. With the Samsung Galaxy S26 Ultrathe Korean company follows the same path. What is happening? Aluminum is back, and everything indicates that it is here to stay. One of the main advantages that titanium promised over aluminum was to promise greater resistance, something that is being demonstrated the drama of the new iPhone 17 Pro and its premature wear compared to previous models. Despite this, companies are returning to aluminum. There is something that both the new Galaxy S26 Ultra and the iPhone 17 Pro Max share: they both have the largest dissipation systems ever built in their families. A titanic effort (to the point of completely redesigning the chassis in the case of the iPhone) to prevent mobile phones from burning in the hand. And there is a key point in this party: we want more and more powerful phones, but someone has to cool them down. Producing mobile phones in titanium is also more expensive, and given the current component crisiswith the RAM shot and internal memories the same wayone of the few cuts that can be made without affecting the overall phone experience is changing the material used. The question about whether we need more power or not, a few years ago, was answered with a resounding “yes.” But for some time now we are not so clear. With configurations of 12 and 16 GB of RAM, and processors that are more powerful than some desktop chips, our smartphones have been increasing power for years without determining too much. Why do we need these new limits?. AI requires RAM and not so much raw power (at least, in the use given to a phone), mobile games are already bordering on the quality of triple AAA console games, and improvements in camera come more through the redesign of algorithms and not so much through increasingly powerful IPS (image chips).

The FBI thought that burning the methamphetamine they had requisition was a good idea. They sent fourteen people to the hospital

by

If you have ever wondered what the police do with the drugs they requisition, surely the Montana Police method, in the United States, does not leave you indifferent. The last stash they have destroyed has made fourteen people have to be treated emergency and has forced to transfer more than 75 animals. What happened. They tell it in Associated Press. The event occurred in an animal shelter in Billings, Montana. The installation has an incinerator for animal corpses, which the authorities occasionally use to destroy illegal substances. In this case it was almost 1kg of methamphetamine. The problem was that, at the beginning of combustion, instead of leaving the extractor, the smoke began to fill the building. They should have had a fan by hand to avoid it, but nobody found it. It is also believed that they did not use the right temperature since, if he had done it, the toxins would have burned and would not have had major consequences. Consequences. Fourteen workers from Yellowstone Valley Animal Shelter had to be treated at the hospital after inhaling smoke. The director of the refuge assured Associated Press that employees did not know that the incinerator was used for such purposes and did not give importance to smoke. Among the symptoms they presented had headaches, throat pain, cough and dizziness. They were not the only ones affected, the animals that were in the shelter also inhaled the smoke. At least 75 dogs and cats had to be transferred to reception houses. Fortunately there was no regret victims. Other cases. It is not the first time that drug burning has consequences of this type. In April of this year, Lice Police, in Türkiye, burned 20 tons of marijuanacausing dizziness, nausea and even hallucinations in some of the inhabitants. In 2015 Something very similar happened in Palmerah, Indonesia. How is it done in Spain. It is also incinerated, but more controlled through concessions with waste elimination companies. According to the independent, In 2022 Spain spent 300,000 euros a year on the destruction of shells on two floors that were in Asturias and Toledo. The Grande-Marlaska Minister did not see viable the construction of a specific incinerator for this because it would mean an even greater cost.

Three years after the Fiasco del Metaverso, Zuckerberg has another burning nail for the goal: digital glasses

by

Mark Zuckerberg believes that in 2030 we will not get the smartphone out of his pocket because We will do almost everything from the glasses. That is his particular new obsession, and he has all the meaning of the world because Meta is in a delicate position. And if one It is cornered In the future that does not control, better create one that can control. Glasses, glasses and more glasses. The presentation this week of the promising Goal Ray-Ban Display and his small sisters (Ray-Ban Meta (Gen 2) and Oakley Meta Vanguard) It is a clear message to the world. Zuckerberg He sees us all Taking glasses in the future, and the new options of their connected glasses are precisely aimed not only to make them more with them, but to get more and more forget about the device that has governed our life for two decades: the smartphone. An event to redraw the target of Meta. In the presentation event of the Zuckerberg glasses, he also confirmed that new silent transformation of his company, which first focused on social networks and then bet on everything to the Metaverso. Now the proposal is different and Zuckerberg made it clear in the event saying the following: “Our goal is to create glasses with an attractive design that offer personal superintelligence and a sense of presence through realistic holograms. The combination of these ideas is what we call” metaverso. “ Metaverso V2.0. Suddenly the metaverse now is different from that before. In that metaverso that seemed A bad copy of Wii Sports We have moved to another in which virtual reality is totally displaced. Four years ago, when Facebook changed its name by goal, there was not even talk of artificial intelligence as part of that platform. Now it is a fundamental part, logically. Metaverso 1.0 – who is careful, is still alive and Also losing money– It has remained In the background. Killing smartphone is going to be (very) difficult. Of course, we will need a device in which to be able to do all those things that Zuckerberg proposes, now the candidate is in many cases the mobile. If not as the center of experience, yes as an important element. Will the smartphone give prominence to the glasses or other hardware products? It seems difficultbut of course both goal and others – Hello, OpenAI+Jony Ive– They are willing to achieve that goal. It is normal: if they achieve it, they can control something they have ever managed to control: the hardware. But. If something has characterized Mark Zuckerberg it is his ease to change focus. After the success of Facebook later seemed to focus much more on WhatsApp Supervitaminar –Do you remember Libra?– Or Instagram. Then, of course, his obsession with metoverso would arrive, and more recently With superintelligence and AI glasses. If there is a new technological fever, the Facebook founder usually goes for it. What will be next? And it will have a lot of competition. It is not that Zuckeberg achieves that we use the glasses more than the phone: no one is going to let it do it alone. Google works tirelessly on Android XR and has already shown us that you will have products in this segment, and Apple also seems convinced that the shots will go here. Not to mention Amazon or – major words – of Chinese manufacturers. All of them are going to put it very difficult at the finish line, but one thing is true: if they manage to move the mobile focus on the glasses, there at least they will predictably have part of the cake.

The US has bought 10% of Intel to save it from burning, and that plans a huge problem. One called favoritism

by

Intel has agreed to sell 10% of your company to the United States for a value of 8,900 million dollars. An interventionist measure is thus confirmed that has huge implications not only for Intel, but for the entire semiconductor industry. Above all, the American. Historical crisis. The Historical crisis that Intel is going without resolving. And his new CEO, Lip-bu Tanalready I recognized A few weeks ago, “twenty or thirty years ago we were leaders. Now the world has changed. We are not among the ten main semiconductor companies.” The mass layoffs and the decision of Bet everything to lithography 18a –No 20th node– They raised a complicated future for the company, which needs maneuvering margin. He has just obtained it, but we don’t know at what price. Or maybe yes. The agreement. According to indicate in IntelUnited States will invest 8,900 million dollars in company shares, and that adds to the 2.2 billion dollars that the US government paid to the company as part of the Chips and Science Acta federal program that was approved in 2022 and is intended to invest billions of dollars to relive the country’s semiconductor industry. Intel was too big to fall. He Moment of weakness It is still worrying, but there have been two recent “bailouts.” The first, by the Investment of 2 billion dollars of softbank In the company. The second, much more important, the one that has just signed the US government with the purchase of 10% of Intel for 8,900 million dollars. This measure is especially striking for several reasons. For a start, is the first time that the US government intervenes a company since the rescue of the car industry was produced during the 2008 crisis. But there are more implications. Potential loss of autonomy. The agreement is only economic and there will be no official representation of the US government in the Board of Directors of Intel. However, political pressure will now be seen without a doubt increased, and each business decision of Lip-Bu Tan and its team will be seen through a different prism: there is public money at stake. Desperate times, desperate measures? Another perspectives from which this agreement can be contemplated is that of despair. Accepting this governmental “rescue” can be seen as a clear indication that Intel was against the ropes and there was no escape without any movement of this type. For Lip-Bu this can represent a problem for confidence in his leadership now that he has just taken command, and in fact the American senator Tom Cotton He accused him to invest in 600 Chinese companies. President Trump He came to ask for his resignation In Truth Social and then end up meeting him and congratulating him for its management. A logical agreement for Trump’s roadmap. The US president began his mandate with the clear intention of centralize semiconductor production to the maximum and electronics products. This protectionism is closely linked to this decision, and allows to protect Intel in addition to mitigating the dependence of Taiwan and the Chips import and technology From China. The Secretary of Commerce, Howard Lutnick, Indian That the agreement is especially beneficial for the US government, pointing out that they were basically giving money to companies through subsidies, but here what the US achieves is to raise that subsidy as an investment. It is not “lost” money. It is not clear that since the money comes from the ACT chips, the US government is allowed to end up obtaining benefits of such “investment.” Favoritism. This politicization of the semiconductor business could end up causing uncomfortable alliances and distorting competition. Now that all kinds of government agencies may have much more inclination to buy Intel chips in the future, while direct competitors such as Apple, AMD, NVIDIA or Qualcomm are harmed before a landscape of government favoritism. Intel, we insist, perhaps it was too big and iconic to drop it, but this intervention raises a change in the rules of the game that affects both Intel and its national competitors and, of course, foreigners.

Google, Amazon and Microsoft have been burning absurd amounts of money in Ia for years. Finally they begin to see green sprouts

by

The AI boom made Big Tech will increase their capital spending to limits that had never been seen. The fear that The bubble will explode Rondaba, investors They started to get nervous and the profitability of AI remains in doubt. The last results are a green outbreak, the first in a long time, although with many buts. The cloud reaches capex. They tell it in The Information. Capital or Capex expenses of the Big Tech in recent years have climbed unstoppable, much faster than their income, but in the results of the last quarter the gap is finally closing, but not because chatbots and other products are being profitable, but thanks to revenue from cloud services. The crazy one is committed to AI is beginning to show a slight green outbreak, even if it is not directly because of AI products. Income from cloud services are approaching capital spending. Source: The Information (click on the image to access X) The four riders. There are two clear winners of the departure, one that already brought the duties done and one that goes free. Let’s see who is who: Microsoft: The clear winner with a Income increase of 25% In the last quarter, mainly thanks to the growth of Microsoft Azure. Google: Record a 20% increase In your income thanks to Google Cloud and advertising. Amazon: falls 7%but it is the only one that was in positive numbers. Amazon Web Services is the largest provider of cloud services and was already profitable, although its growth is beginning to slow down. Goal: Your income grows 22%but they basically come from advertising. Goal does not sell cloud services, so it does not generate income directly. Indirectly, yes: AI has allowed them Improve the efficiency of your advertising business. Burning money. The increase in capex by AI has reached madness figures that had never been seen in other technological booms. By the end of 2024 we talked about investing a real barbarity In data centers: Microsoft 30,000 million, Goal 35,000 million, Google 25,000 million… The dizziness figures, and have not stopped increasing. Amazon said at the beginning of the year that He wanted to spend 100,000 million in data centers for AI and goal is building several data centers whose combined cost could rise to 200,000 million dollars. Skepticism. This excessive spending frenzy soon unleashed a wave of skepticism. AND If AI is another bubble And is it about to explode? Milmillionaire investments are not translating in income. Even Satya Nadella himself, one of the protagonists of this revolution, was skeptical because At the moment no one is making gold with AI. It is not that they are not making gold, it is that nobody is earning money. In their newsletter, Ed Zitron had accounts And the difference between what is expected to spend in 2025 and the return that is giving them the AI is not that it is a reason to doubt, it is directly no sense: Capex planned in 2025 BENEFITS IN IA IN 2025 Microsoft 80,000 million 13,000 million Google 75,000 million 7.7 billion Amazon 105,000 million 5,000 million goal 72,000 million 3,000 million Green outbreak Yes, in singular. The latest results are hopeful, but we are very far from being able to say that AI is a profitable business, especially As far as generative AI is concerned. Good results are thanks to cloud services, chatbots or audio or video generators are not profitable. Subscriptions to these tools are a way to monetize, but The income they generate is child compared to spending. Despite doubts, unbridled expense has not stopped and this green outbreak can be more than enough for investors to continue throwing banknotes to the AI well.

Take cars from China to Mexico. It sank with 3,000 vehicles on board after burning

by

It was called Morning Midas. Sailed on May 26 From the Chinese port of Yantai with more than 3,000 vehicles on board and destination to the Mexican port of Lázaro Cárdenas. It never arrived. On June 23, after several weeks to drift for a fire on board, the freighter He sank into deep water From the North Pacific, more than 600 kilometers southwest of Adak, in Alaska. It disappeared in silenceleaving behind a trail of smoke, steel and cars that will never touch the mainland. The fire began on June 3. According to the United States Coast Guardthe smoke came from the roof where electric vehicles were. On board 22 crew members were traveling. Everyone managed to evacuate in time in a lifeboat and were rescued without injuries to the freighter Cosco Hellaswhich was in the area. A freighter that remained to the Mercer in the middle of the ocean For days, Morning Midas was drifting, still wrapped in smoke. Rescue teams worked alongside Zodiac Maritime – the British ship of the ship – to evaluate the situation and prepare a possible recovery. But he didn’t have time. The combination of structural damage, bad weather and water entry ended up sinking it more than 5,000 meters deep. The cargo was as valuable as revealing: 3,048 vehicles, including 70 electric and 681 hybrids, According to data updated by the Coast Guard After verifying the information with Zodiac Maritime. Each unit possibly already had an assigned destination: a dealer or a buyer. Now they rest at the bottom of the ocean, without any possibility of recovering them. Morning Midas The history of Morning Midas clearly illustrates the scope of maritime car transport, a global chain that we rarely see but holds the flow of millions of vehicles a year. It also remembers other recent episodes. In 2023, the Fremantle Highway freighter, with about 3,000 cars on board –including about 500 electric-,burned for days at the North Sea. A crew member died. The ship ended up being towed to a port after a week of uncontrolled fire. Morning Midas That case led to the Dutch authorities to demand urgent improvements in emergency protocols for this type of transport. Since then, the focus on the difficulty of containing fires into ships that transport cars has been made. Morning Midas Zodiac Maritime has deployed several ships equipped with Anticontamination systems To monitor the area. According to the Coast Guardno discharges have been detected to date, although the risk is still present: the ship He transported 1,530 tons of fuelulo of low sulfur content and another 350 marine diesel. Maritime car transport is a key piece of industrial gear. And while loading more than 3,000 units on the same ship may seem shocking, the truth is that today is almost common. Manufacturers such as ByD have begun to operate their own ships. One of them is already in service and can move up to 7,000 electric cars on a single trip. It has not yet been confirmed whether the fire aboard the Morning Midas is related to any of the electric vehicles he transported. What is clear is that this type of incidents occur in full electric car boom. Each route that is planned is part of a learning process. And even if we still have no answers, there is a question that resonates: are we safely transporting thousands of high voltage batteries per sea?

Waymo Robotaxis have become a weapon for police control. And in Los Angeles they are burning them

by

What started as a protest against raids Anti -immigration in the United States resulted in bell battles in the streets of Los Angeles and the mobilization of 2,000 national guard and 700 Marines. This morning. Donald Trump has confirmed that he will double the forces of this first body and, before the doubts about your legality, has confirmed that 4,000 troops will be deployed of the National Guard. For four days, the tension has increased to the point of confronting against the police, attacking various shops and burn cars. And in the middle of this whole fight, there is a clear affected by protests: Waymo. Click on the image to go to the original tweet Waymo, objective of protests No t -shirt, with the face covered and waving a flag of Mexico uploaded to the roof of a completely vandalized Waymo car. It is undoubtedly one of the most representative images of the protests that are being carried out in the United States. “Sometimes an image says everything to say”, Aldo Butazzoni points out in its publicationconservative journalist who is following the disturbances in the street. Getting to the Waymo vehicle roof is no accident. The company that has active a robotaxis service in the city is being one of the companies that are receiving more attacks, seeing how protesters completely destroy their cars. Last June 8, A photograph went viral. He showed at least three vehicles on fire. The company raised the figure to five cars and confirmed that it temporarily paused the service before the protests. In Los Angeles Times They assured that the protesters came to launch shared scooters of the Lime company against vehicles to access the interior. In his photographs a person is also seen trying to break one of the front windows with a skate table. But why this virulent attack on the company? Beyond the obvious damage to urban furniture with the burning of these cars and the intention of making difficulties to the police work, everything indicates that the company is being hard attacked by the protesters for deeper reasons. Since Waymo launched, attacks on the company have been multiple. In July last year, a person was accused of clicking the wheels to 17 Waymo vehicles. But it has not been the only vandalism, the previous months caught fire and destroyed the company’s cars in Los Angeles and San Franciscowhere they also operate. “Waymo lacks humanity. It is expensive and politicians, who have encouraged it, use it as an excuse to stop financing public transport. I hope Waymo collapses. With these words, Elise Joshi, well -known climatic activist, his position against Waymo attacks these days in these days explained in these days A publication in X. The Waymo service has always been surrounded by controversy. Although they are already approaching the 800,000 monthly travelersthe company has had to deal with the opposition of those who see in the service an attack against public transport, one more tool of the great technology of earning money without using people and a problem in day -to -day mobility. In recent years we have seen, for example, how Erobotaxis services caused various mobility problems. Some of little importance, such as almost 600 fines that accumulated Waymo cars for parking where they should not in a single year. But also more serious, like Cruise’s car than parked on top of a woman hit or the vehicles that complicated the work of firefighters. Those derived from the impact of these robotaxis companies are very wide. To the point that there are those who have questioned If they are the cause of more housing problems in cities like San Francisco. Constant surveillance There is another great derivative of why Waymo cars are constantly attacked. Beyond the social or political positioning before the service, when someone vandates a Waymo car ensures that it cannot be used by the police. They point out in Time that police forces are using Waymo cameras recurrently in their research. Each Waymo I-Pace Jaguar has 29 cameras to control everything that occurs around. That makes them a powerful asset for the police. In 404 average They published last April that the Los Angeles Police Department This video uploaded to YouTube To ask for citizen collaboration when locating the driver of a vehicle that would have hit a person in an accident that had nothing to do with the performance of the Robotaxi. In that article, Waymo said that he studied in detail all the requests of the police and that he did not deliver images indiscriminately but in Bloomberg They already pointed out in 2023 that the procedure for helping these vehicles was increasingly common. In fact, the media indicated that not only Waymo has been appealed by the police when collecting information for an alleged crime. Order forces too They would have asked for images To Tesla, according to the economic environment, since their cameras are recording at all times what happens around them. In fact, Elon Musk’s company has been accused of record their own owners in their homes without them knowing it. “We have known for a long time that they are essentially wheel surveillance cameras,” said Chris Gilliard, a merit member of the Carnegie Council for ethics in international affairs to Bloomberg. “We are supposed to be able to make our daily lives without being persecuted unless we are suspected of a crime, and every bit of this technology eliminates that capacity,” he concluded.

The burning is one of the most mysterious sites in Mexico. And their fire craters continue to baffle archaeologists

by

Mexico is a archaeological treasure And, although the Yucatan Peninsula be the one that usually monopolizes All eyes due to Mayan ruins and initiatives such as Mayan train for enhance tourismthe central area of Mesoamerica It is home to other relevant archaeological sites. One is the burned one, which is said to be the original place of The Aztecsand, although there are several mysteries associated with the place, a study He has focused on analyzing the enigmatic fire pits. It is not known if it is where the Mexicans were born, but they have discovered when they lit and ventured to decipher for what they served. Chicomóztoc. Located in a privileged central area of ​​Mexico, it seems clear that, due to its location, natural resources were abundant, being able to be a strategic area for nomadic peoples to supply. At some point in 300 AD A town settled in the placewhere what would later know as “the burned one” was founded. The site reached its peak towards the 800 AD, when it began to fortify strongly to compete against nearby locations, and took place until 1200 AD It is estimated that it was then when a progressive abandonment and, When the Spaniards arrivedthey found ruins with numerous fire traces. Legend has it that, because of this, they baptized the site as “The burned”And it was Francisco Javier Clavijeroin 1780, who associated the site with the mythological original place of the Mexica: Chicomóztoc. Part of the citadel and pyramid The patio of columns Archaeological zone. Located on a hill, the burned one has numerous architectural remains. Using mortar, stone and vegetable fiber, its inhabitants built a series of buildings whose purpose does not differ from that of many others Archaeological sites from Mexico. Thus, we have defensive structures such as a wall of four meters wide and up to six high, or one 70 -meter long ball courtbeing of the Longer Mexico. Also ceremonial buildingslike the votive pyramid About 12 meters high, the Hall of Columns or an Observatory that would serve to monitor and that could also have had astronomical functions. The function of the different elements is more or less clear, but there is something that has confined archaeologists for a long time: huge holes. The holes. The inhabitants of the burned were built in phases about the old structures, but something that stands out is that the recent analysis performed by archaeologists points out that the holes were used at all times. There are several, but they focused on five of them called from LQ1 to LQ5 and, through the Archeomagnetism techniqueThey have been able to identify when they were active. This technique is like reading a fossil compass that allows you to know how many years a clay or stone material has been very heated. When this occurs, internal minerals are oriented according to the Earth’s magnetic field At that time, being “recorded” the orientation forever. It is something that allows the rocks to be dated and find out when it was the last time that element was heated. Thus, they identified that the LQ4 and LQ5 holes were used in the apogee era, between 675 AD and 903 of the LQ1 was lit between 927 AD and 1101 AD and the LQ2 showed more confusing data, but they estimate that it can be the oldest. And from LQ3 no data were obtained. Mystery. Several theories have been established on their use, some pointing to harvesting ceremoniesothers linked to change of stations and also those that suggest that they were torches for night ceremonies. This mystery will be difficult to solve, but as we read in The green compassLQ1 is the one that has caught the attention of researchers. “Its date coincides with the collapse of the site, so perhaps the rituals persisted until the end, as a symbolic farewell,” they say. In addition, it is the closest to the votive pyramid. The different dates of use of the holes, however, reinforce that theory that abandonment was gradual and that, even in the last moments, “the fire could be a way to keep the memory of the place alive.” As we say, it will be difficult to clarify What kind of ceremonies were celebrated In them, but the next step of the project is to study the rest of holes that have not yet been excavated.
