Tired of people talking about the end of the world without knowing, Newton decided to calculate it. And he explained it in a letter of 1704

by

By 1665 the bubonic plague arrived in London in a cotton ship from Amsterdam. In the following years, between overcrowding, dirt, hunger and rats, they would die More than one hundred thousand people In the country. In August, the great plague arrived in Cambridge and forced the university to close. It was then that a very young Isaac Newton had to return to Woolshorpe Manor, the family home. Over there, According to a probably fraudulent traditionsat down one of the three apple trees of the farm and the blow of one of the fruits brought to mind the theory of gravity. We do not know if the craniocerebral trauma produced by the happy apple was also responsible for everything that came in the last part of his life. Sir Isaac Newton was not any. On the one hand, Newton was, in fact, an intellectual giant. “The greatest scientific brain that the world has known,” According to Asimov; the person responsible for that “perhaps the greatest advance of thought that a single individual has ever done”, According to Albert Einstein. “Nature and its laws were hidden at night; God said ‘that Newton’ becomes and made the light,” he says Alexander Pope’s famous epitaph. On the other, it was someone complicated – especially after The nervous breakdown he suffered in 1693. The most controversial example is its passage through the house of La Moneda de England (a stage of your life Full of torture, hanging and dismembered falsifiers); However, a brief review of his personal life and friendship gives good account of it. But what interests us today is that he was passionate about the Bible. It is estimated that more than half of what Newton wrote It had to do with theology and alchemy; And, as a good mathematician, one of the themes that worried him most was the end of the world. The end of the world? Yes, at that time (remember that The English revolution had just “finished”) Religious debates were in the flower. And the end of the world was a usual issue in public conversation. But Newton was convinced that people did it wrong. Lincolnshire’s genius analyzed the biblical text (And, specifically, Daniel’s book and the Apocalypse) and concluded that people were exaggerating the closeness of the end of the world. And gave a date? Yes and no. As Newton seems to identify the year 800 d. C. as the moment when the Church entered the “great apostasy.” This is a key date in the texts and, from there, he deduced that there was no reason to think that before 1260 years the apocalypse arrived. That means that We are relatively safe until 2060. Because, as he said “he may end later, but I don’t see any reason for him to end before.” But did he really think he was going to end the world? According to Stephen Snobelen, professor at the King’s College University of Halifax (Nueva Scotia) that has studied the matterNewton did not believe that the world would end in a literal sense. “For Newton, 2060 AD would be rather a new beginning. It would be the end of an ancient era, and the beginning of a new era: the era to which the Jews refer as the messianic era and the era to which Christians premillennials call the millennium or kingdom of God “, Snobelen defended. Obviously, we are not faced with weight to think that the apocalypse is just around the corner. But knowing The close we are from the end of the worldwe can take all this as an invitation to take advantage of the moment.

break with Castilla and become autonomy

by

Thousands of people, 13,000, according to Police calculationsthey left yesterday to the streets of León to demand a better future for their province. So far not surprising. The funny thing is that at least a significant part of the attendees imagines that future in a different administrative scenario: in a lion separated from Castilla, which has ceased to be province to become the 18th autonomy of Spain and no longer looks at Valladolid as its de facto regional capital. That there is one Autonomist drive In the province it is not a novelty. Years ago that their defenders cry because the region courts its administrative ties with Castilla. Yesterday’s march served however for something else: show to what extent that feeling has become strong and lets hear in the province. It was about showing muscle. And he did. A figure: 13,000. That is the number of people who mobilized yesterday in León to demand a better future for the province: 13,000. At least According to the accounts Police officers, because there are those who speak of several tens of thousands And the organizers of the march point to many more, around 50,000. It is good for one or another figure, the undeniable thing is that thousands of lions took the streets of their capital between flags, banners and songs to wrap a march called by The main unions and backed by 60 groups to defend the future of the region. Your motto: “More solutions and less stories.” Click on the image to go to Tweet. What did they claim? “Definitive Solutions” For León at the economic and sociodemographic level. But not just that. Like the march held just a five years, The 16-F of 2020yesterday’s demonstration served to show the discontent of the Leon with the situation in their province; But also for something else: to make clear to what extent the idea has gained strength that the future of León must go through conquering greater administrative autonomy against Castile. León News covered the act and He recounts that during the manifestation, shouts of “Autonomy of the country” were heard and banners were shown in favor of autonomy. Also flags that cried out for “autonomy 18” or “Lexit”label that (in a wink to Brexit) has made fortune thanks to the combination of “León” and “Exit”. The idea of ​​autonomy was so present during the march that today They are not few The media regional ones that dedicate its headlines. Why is it important? Because yesterday’s march acts in a certain way of thermometer, one that helps to understand the discomfort in the province with its current situation and the interest raised by the lexit as an exit. Both when it comes to figures (between 13,000 and 50,000 attendees in a city of 122,200 neighbors) as social support. Although over the last months it has been clear that Not all Come with good eyes with Castilla, yesterday’s day shows, at least, that León believes that he must fight for “The future that deserves”. “More solutions, less stories”. In the head From the demonstration at his exit from San Marcos lucia a banner that prayed “León + Solutions – Tales”, a message focused on the struggle for better infrastructure, reindustrialization, employment and public services. And it is undeniable that the message fell. The appointment attended representatives of most parties with weight in the province, The mayor of Leónthe president of the Diputación and members of social groups. Click on the image to go to Tweet. Beyond the streets. Yesterday was not the first sample to what extent the Lexit has penetrated in the region. TO late 2019 Several parties joined their votes to claim the autonomy of the Leonese region and become the 18 Spanish community. The idea: separate from Castilla with Salamanca and Zamora. After the pandemic the drivers of that measure organized An act To remember that they did not give up and last year, in a new step in that same direction, PSOE and UPL added their votes to claim autonomy in the Diputación de León. Not everyone thinks the same, of course. In 2024 the PP already marked distances with the autonomist motion and advocated looking for a “Useful Leonism”. “The community has been failed”. Proof of how living the claim is that the mayor of León, the socialist José Antonio Diez, recently presented a legal report to guarantee the Lexit. “We are clear about the mandate and will of the Leon, who have opted for their own community, and the Constitution supports us through the article,” José Antonio Diez claimsof the PSOE, who defends that “the current community has been failed.” “We never wanted to be part of Castilla.” One question: Why? Because the province of León lidia with worrying data at the demographic and economic level. Four years ago I added 451,700 inhabitants, 13% less than in the mid -90s and 2024 data They suggest that it would be below 448,000. In a scenario marked by the urban exodus and the bleeding of the Mining municipalitiesLeón has also become one of the territories that More population loses from all over the country. And his business balance is not especially good either. The latest data released over 2024 show that it lost 144 contributing businesses In just one year, which is equivalent to the more or less 50% of closures In autonomy. Interesting yes, new no. The discomfort of the Leon is not new. A five years ago, the 18F of 2020, already encouraged Another mass march During which shouts of “autonomy, Leonese country” could already be heard, in tune with those who launched yesterday. “The Leonese go out to demonstrate, basically to change the territorial framework that impoverishes us,” He explained yesterday A UPL attorney. If something showed the day is that it is not the only one who thinks so. Image | CCOO CASTILLA Y LEÓN In Xataka | Castilla-La Mancha is about to shrink 2,000 hectares in favor of Aragon.

Hubble investigates whether a star has “pretended” his own death

by

The Hubble has given us a new image. It is an image with history behind, even if it is not a story that can be appreciated at first glance. A story of false appearances. Image of the week. The last “week of the week”Of Hubble Space Telescope shows the UGC 5460 galaxya galaxy in which a few years ago we detected what we believed were two supernovae. However, one of the outbreak could have been the result of a very different phenomenon: a blue luminous variable. SN 2011ht and SN 2015as. A few years ago, the UGC 5460 galaxy He witnessed two great events to those that astronomers called SN 2011ht and SN 2015as. Their names refer to the fact that they were classified as Supernovas (SN) and the year in which they were discovered (2011 and 2015) SN 2015as was listed as a Core collapse supernovaa type II supernova that occurs when the nucleus of a massive star (stars more massive than our sun) is left without “fuel” for fusion. This means that the nucleus ends up implicating because of its own severity, after which there is a kind of rebound effect. The result: a “cataclysmic explosion”, as explained by Hubble. That is what happened with SN 2015as And it could also be what happened with SN 2011ht. But astronomers have another open hypothesis to explain this last outbreak. Appearances can fool. A hypothesis with its own name: blue luminous variable (LBV), a “impostor” star capable of making astronomers fall into the mistake of confusing it with a supernova. The blue luminous variables are stars that occasionally generate eruptions of such magnitude that can be confused with supernovae. However, these outbreaks do not occur at the end of the life of these stars. Rather they seem to represent points and apart in the life of This type of stars. LBVs are huge and unstable stars. They are also relatively Uncomowhich implies that what we know about them is not much. While we know that the eruptions of the LBV do not represent the final explosion in the life of these star objects, astronomers They believe that they are an indication that the star is in the last stages of her life. A kind of final track, more than a lethal collapse. Observing UGC 5460 to search for clues. That is why SN 2011ht is a unique opportunity for the instruments of the veteran Hubble to direction their attention to UGC 5460. The image, in which four wavelengths of the electromagnetic spectrum are combined will allow astronomers to learn more details about supernovae such as SN 2015as and, perhaps, help us solve the unknown about the nature of the outbreak observed four years before. And we may be able to unmask (for now alleged) “impostor.” In Xataka | NASA is developing a Hubble super telescope capable of observing exoplanets.

In LaLiga Cloudflare IPS blockages they are paying fair for sinners. The righteous are already proposed legal actions

by

This weekend They turned to produce Problems for many Internet users who failed to access the websites they visit normally. The reason in many cases was the Cloudflare IPS blockade that several operators carried out due to LaLiga’s demands. Users reaches. As we explain, the war between these two entities comes from afar, and the worst thing is that is causing them to pay fair for sinners. However, some of those righteous are preparing to take action on the matter. Affected in action. Román Ramírez (@patowc), cybersecurity expert and event organizer Rootedconhe published last Friday a message in X (formerly Twitter) encouraging those affected to contact him. The objective, to ensure that those who had suffered the problems offer evidence of it to be able to collect them and gather enough evidence. Legal actions in sight. Javier A. Master (@Javieramastre), who exercises (among other things) as a lawyer from Rootedcon, recently explained the legal details of these actions and is part of that effort of Ramírez to clarify what is happening. Both are convinced that LaLiga is in a clear illicit, and that the legal arguments of that organism are not valid. Freedom of expression. For Ramírez, fundamental rights such as freedom of expression are being violated, “which should not be above economic interests.” Meanwhile, Javier Tebas, president of LaLiga, published a message in x accusing Cloudflare of being “perfect accomplice” of criminals who, for example, publish child pornography on the Internet. In that message, says Ramírez, Thebes himself explicitly admits that he is causing damage to third parties, something that theoretically should not be able to do LaLiga if he complied with the law. Shared IPS. The fundamental problem is, as we have already mentioned, that LaLiga requests IP addresses to avoid illegal broadcasts of IPTV football matches. The problem is that in many cases these IPS belong to Cloudflare, but those IPS are shared and if you tomb the IP, you tomb all web sites and services that depend on said IP. Cloudflare does not collaborate in LaLiga. According to LaLiga, Cloudflare does not collaborate at the closure of the IPTV service of the offenders. However, Ramírez explains that what LaLiga demands is to have “total access to her backend.” Cloudflare knows, of course, the web sites and services that “hang” from the same shared IP, but one of its premises is to hide that information – for that the protcolo ECH is served – as well as protect that information and its customers precisely to avoid cyber attacks and BLOCKS. The ideal solution. Cloudflare could thus leave only the website or server that is committing the alleged infraction, but that should be dictated by a judge. The current laws allow LaLiga to send a weekly IPS list to block, and from there the operators must block them or would be exposed to the breach of the judicial mandate. Ideally, a judge, knowing IP address and domain or even the SNI (Server Name Indication), demanded the closure of that exclusive service. Thus Cloudflare could disable that access at the request of the judge and not of the head of the property rights of the issuance, which is the one who demands that indiscriminate block and that affects legitimate websites and websites. Evidence. Those affected who want to provide evidence can do so by contacting Román Ramírez via X (@patowc), as writing to the email address info@rootedcon.com. The objective is to collect as many evidence as you can in the next few days to see how hundreds and even thousands of legitimate websites are inaccessible during soccer matches. And possible demand. With all those data, Ramírez and Maestre hope to build an expert case and report with which to execute a potential demand to LaLiga. The ultimate goal is to raise a complaint with which to apply precautionary measures and that these IPS blocks are suspended.

15 years ago, a forest engineer decided to grow sponges in Galicia. The war against plastic has ended up giving him right

by

In the mid -90s, Juan Carlos Mascato finished studying forest sciences in Hamburg and enrolled in a company in the area. He was lucky: of all the things that company could have needed, he needed someone to speak Spanish, someone to send to Paraguay. It was then that he met the Lugfa and began his crusade against the plastic. Today is the largest producer in Europe in the sponges and natural scourers. And all from a small town in Pontevedra. What is the LUFFA? The LUFFAS are a genus of plants slightly related to pumpkins, cucumbers and melons. In fact, in Southeast Asia is a Very popular food as long as they are collected soon. Otherwise it becomes too fibrous to be consumed. So fibrous that, duly processed, they can be used as exfoliating sponges. For centuries, this type of vegetables (or some of its variants) were widely used and were among the crops of any orchard that would be precious. But the irruption of plastic from the 40s sent them to the drawer of history. Until now what THE WAR OF THE PLASTICS They have returned them to the first line. And what does the European Luffa giant do in Caldas de Reis? It is an excellent question. As Silvia Rodríguez explained in the countrythe clearest reason is that the Mascato family (of German mother, but Father Gallego) had a farm available in a town with a very particular climate that made it a good candidate to try subtropical crops: Caldas. Chance does not end there, of course. Because the processing of the LUFFA includes a fermentation phase in which the hot springs of the Gallego municipality fit as a ring to the finger. No one is a prophet in their land … And in this case it doesn’t happen either. Because the truth is that Iberian vegetable sponges It is little known here in the country. Of the 200,000 sponges that manufacture a year, only 10% stay in Spain. The rest goes to countries such as Korea, Taiwan, New Zealand, Sweden, Finland, Norwegian or East next … Right now, the company works on an online marketing project in Germany and expanding its productive infrastructure to the US. What sponges can teach us. Because although the story is already very interesting, there is something that really crucial: that for decades we have despised many traditional solutions simply because they were. And that is a mistake. This was made clear in 2015 Karolinska Institute of Stockholm when granted your youyou The Nobel Prize in Medicine. Many interpreted him as a prize for traditional Chinese medicine, but it was not accurate: your feat was incredible. Since 1965, your youyou It was analyzing thoroughly Each and every one of the remedies that the millenary Chinese civilization had been selecting. And, indeed, most pure superstition, pseudoscience and placebo. However, he found the Artemisininea revolutionary treatment against malaria. Rethink the past. This is an example of the book that if we approach us with an open (but rigorous) look at the technological history of humanity, we can find really creative solutions to the problems of our day to day. In the middle of a world invaded by plastics, natural sponges are an excellent example.

Microsoft will publish more in PlayStation than in Xbox

by

Last week the PlayStation State of Play He had to speak: we could comment on the appearance of a lot of new franchises, which is what It really gives life to a system. Almost all of them multiplatform, by the way, what made fans comment that Xbox may have abandoned the fight to focus on taking games for all formats, but PlayStation does not lag behind in regard to feeding his Catalog of non-exclusive. Multiplatform for all. ‘Monster Hunter Wilds’, ‘Lost Soul Aside’, ‘Borderlands 4’, ‘Split fiction’, ‘Directive 8020’, ‘Metal Gear Solid Delta: Snake Eater’ or ‘Tides of Annihilation’ will arrive at least, at PC separately from PlayStation, and many of them also to Xbox. This is the reality to be used to: once the war of exclusive is almost closed, The multiplatform takes control. The industry is clearly evolving in that direction. The hardware, for the soils. Microsoft has been experiencing a vertiginous fall in hardware sales. His reaction has led him to develop a strategy that has made almost all his exclusive games also come out on PC (strategy imitated by PlayStation, whom a few years ago we would not have seen franchises such as ‘Spider-Man’ or ‘God of War’ in computers) and, later, also in PlayStation. Without a doubt, strange times for a crisis economy and scratching benefit anywhere. Microsoft will publish more in PlayStation than in Xbox. This He affirmed from his X Ryan McCaffrey accountIGN editor, and that perfectly summarizes the paradox of the time we live. In fact, significant Xbox brands, until now insepociable from the Microsoft and PC console, will appear on the PlayStation: ‘Forza Horizon 4’, ‘Age of Empires’, and also recent titles that, given its origin (Bethesda, company owned by Microsoft), logically it was thought that they had the possibility of staying in the Xbox ecosystem, such as the last ‘Indiana Jones’. And although they have not been announced, everything suggests that games that already start with multisystem wood, such as “ South of Midnight ‘,’ Avowed ‘and, perhaps,’ Fable ‘, end up in PlayStation. Logos is what is sought. In one Xboxera interviewPhil Spencer specified a detail about its passage to other consoles that is still a trifle, but it is tremendously significant: for a long time in the ads of its games, logos of other platforms appear in which the titles will also come out. Spencer says that “I think it’s simply honest and transparent about where games will be available. (…) If a game comes out in Nintendo Switch, we will say it. If it comes out in PlayStation or Steam, too. People must Know what platforms our games can find. ” The policy that now Xbox is not machines, but the screensat its maximum expression. Everything reaches the PC. Only the most blinded fandom by the need to take sides between one of the consoles can deny the obvious reality that the platform that all the releases arrive is the PC right now. Steam, the most popular PC store, makes very notable efforts to consolidate the experience of a game, and machines such as the Steam Deck They are both laptops to play, but also consoles without more complications.

Eliminate a key phrase from your website

by

It was recently revealed that Taiwan had signed an agreement with the United States so that His army stayed two years on the island training their troops. Days later, it was learned that The island had activated an unpublished security plan to preserve your submarine cables. The maneuvers, without saying it, had a clear recipient. China’s response was A simulation “of war”. Now the United States has raised the tension a little more. And all for a simple phrase. A subtle but significant change. The United States Department of State He has eliminated from his website the phrase that explicitly pointed out that Washington “does not support Taiwan’s independence”. No doubt, this adjustment in the language, which maintains the opposition to any unilateral change of the status quo On the part of China or Taiwan, it has been interpreted in Taipei as a support signal. In addition, the updated document Mention Taiwanese cooperation with the pentagon in technology and semiconductorsand reaffirms the support of the United States to the inclusion of Taiwan in international organizations “where it is applicable.” China’s response has not been waiting. What does Taiwan say. Taiwan Foreign Minister Lin Chia-Lung described the change as A “sample of support and a positive posture” in bilateral relations. We remember that, in 2022, a similar elimination of the same sentence generated controversy and was reversed the following monthreflecting the delicate diplomacy around the status of the island. On the other sidewalk, China, that Consider Taiwan an inalienable part of its territory and its “central interest of interest”he has always reacted with hostility to any gesture of support to the island by Washington. While the Taiwanese government insists that only its citizens can decide their future, Beijing sees any movement in favor of Taiwan’s sovereignty as a provocation. Military movements and regional pressure. We have been telling In recent months. The context of these tensions arises from China’s growing military pressure on the island. If we are going very far, a few weeks ago the Taiwanese Ministry of Defense reported that 24 Chinese military planes made joint combat patrols along with warships around the island. In parallel, The American Navy made its first transit through the Taiwan Strait since the inauguration of President Donald Trump last month, while A Canadian war ship, the Ottawa, also sailed around the areain a sample of support for regional security. The role of the United States. Ironically, The nation does not maintain formal diplomatic relations with Taiwanbut it is its main international ally and is legally committed to providing the means for its defense. Although Trump’s administration has generated uipei in Taipei with criticism (and tariff threats) about the Taiwanese semiconductor industryhe has reaffirmed his support for the island in terms of regional safety and stability. In addition, the new Trump administration He has generated special concern in Beijing due to the composition of his foreign policy teamin which figures known for their hard position against China stand out. Among them, the new Secretary of State, Marco Rubio, has been a firm defender of Taiwanpromoting legislation to strengthen ties between Washington and Taipei, including in the equation The speed of arms sales to the island. China’s response. And finally, the response to the Washington movement came. China has issued few hours ago a strong conviction against Donald Trump’s administration after the elimination of the phrase “We do not support the independence of Taiwan” of the website of the United States Department. Not just that. Beijing has described modification as a “serious regression” in the American position and a erroneous signal to Taiwanese independence movements. In fact, the Chinese Foreign Ministry He has demanded Washington “to immediately correct his mistake” to avoid “even greater damage” In bilateral relations, already stressed by the return of that policy that accompanies Trump marked by the AMERICA First. Guo Jiakun, Ministry spokesman, accused the United States of using Taiwan to contain China and warned that these types of movements should be handled with “extreme caution.” In short, China has made clear (once again) that Consider Taiwan an impassable red line and that any support from the United States to the island will be seen as a provocation. Under this scenario, the elimination of the reference to the non -independence of Taiwan on the website of the State Department could be interpreted as another step in the deepening of the American support to Taipei, feeding, if possible, a little plus the tensions in The region.

During the last five years the modular and compact fission reactorsknown as SMR for its English denomination (Small Modular Reactor), have monopolized all the prominence. These machines are called replace reactors of nuclear fission Conventional because, without investigating their peculiarities, they are smaller, clean, safe and cheap. However, it is currently innovating in this field beyond the reactors. Another area to which some research and companies are dedicating their resources is the fuel used in this form of electricity generation. As we explain in the article we publish after visiting The fuel bars factory That the Spanish public company enusa advanced industries in Salamanca, the fuel usually used in the fission reactors is made up of slightly enriched uranium oxide (never above 5%). This means that at most only 5% of the total mass of uranium is the Uranium-235 isotope (which is the “easily” fistable), while the rest is mostly Uranium-238. It may seem that there is very little uranium-235 in front of the total mass of uranium, but in reality this amount is sufficient to sustain the reaction of nuclear fission. On the other hand, this is the proportion set by international regulations for the production of fuel for nuclear power plants. An interesting note: nuclear weapons use high enrichment uranium, so more than 90% of the total mass is Uranium-235. Lightbridge Fuel is ready to replace the conventional fuel To manufacture the fuel bars used by most of the reactors in operation, it is necessary to subject the uranium to the mixing, pressed, sintering, rectified and inspection processes. These procedures are carried out in an area of ​​the factory known as the ceramic area, and the mechanical area takes over to manufacture the combustible elements that will finally go to nuclear power plants. What the American company Lightbridge Corporation proposes with its Lightbridge Fuel nuclear fuel is different. The main contribution of the Lightbridge Fuel fuel is that in its production a process known as coextrition is involved Its fuel has been designed to be used in light water reactors and existing heavy water pressurized, so it has been developed with the vocation of replace traditional fuel bars. The main contribution of the Lightbridge Fuel fuel is that in its production a process known as coextrition is involved. It consists of covering the cylindrical pills of impoverished uranium and zirconium with an alloy of zirconium and then subdue this structure at high pressure in a die with the purpose of shapeing a cylindrical rod of approximately 2.4 meters long. Circonium alloy used in the coating is crucial to confine radioactive fuel within the nuclear reactor. In any case, the really important thing is that according to its creators the Lightbridge fuel fuel Stop in several key parameters to the conventional fuel. “By integrating the uranium and zirconium alloy with a nuclear degree coating material we are improving the safety, efficiency and fuel performance,” Assures Scott HolcombeVice President of Engineering of Lightbridge Corporation. If this fuel finally exceeds all relevant security tests and is approved by the regulatory authorities in the future, it can also be used in modular and compact reactors (SMR).

In the mid -80s of the last century there was a category in the World Rally Championship in which vehicles of just 1,000 kilos They flew on the roads of ground driven by up to 600 hp. It was the golden era of group B of Rallyes, and the risk of driving these four -wheeled missiles made this category be eliminated, this category was soon eliminated, Leaving legends as the Lancia Delta S4 Integrale, Audi S1 ​​Quattro and Peugeot 205 T16. The only requirement for brands to participate in this category was that the car that competed had At least 200 approved units for street. Ford designed the RS200 specifically for this test, and manufactured 200 units to comply with the regulation share. That, in itself, already makes it a Very quoted piece For collectors. But Ford went a little further by giving another twist to exclusivity and made 20 of them under the distinctive S (from Special) in his name. He Canadian Murray Dewert He was in charge of refining his engine by adding 100 hp more to the 200 hp that already mounted the “standard” RS200 model. The intense story of the RS200 s Ford The RS200 Ford was specifically designed for Compete in Rally Group B And he appeared in the mid -80s, highlighting for his total traction. Ghia designed an ultralight fiberglass chassis, and installed a 1.8 -liter turbo engine, developed by Cosworth, capable of generating up to 450 hp in its competition version. Therefore, the 20 units of the RS200 s was a street car, but with only 100 hp less than the competence on the tracks. However, group B’s competitions were canceled in 1986 due to numerous fatal accidents suffered by cars that participated in this category, which resulted in Several deaths both among pilots and among the audience due to frequent track departures. That left the RS200 without the possibility of demonstrating its maximum potential on the slopes. Despite this, the highway approved units gained value as collection pieces due to their advanced technology and exclusivity. The Ford “Rosso” The Exclusivity of the RS200 S Ford that concerns us is not so much in its poor global production, as in being a RARE Av For collecting, of which even There is a video of the moment in which Ford gives it to those who now sell it. Within the RS200 s variant with higher performance, only four were painted with an unpublished special color in a Ford car: the Red Ferrari. That makes these units some extremely rare pieces, if it also takes into account that It is estimated that only two Of those four units they have come to this day. This finish was not part of the original factory design, but a specific application that makes it even more unique and special for collectors and enthusiasts. A Treasury for Collectors The model that goes to the market on February 22 in the auction house Iconic auctix It is unit 138 and has been carefully maintained and has 32,186 kilometers in the odometer, which is unusual for a car of this era. In addition, it has been reviewed by specialists, ensuring that is preserved in excellent conditions both in its mechanics and in its body. This detail guarantees that it is not only a collection car, but a fully functional and ready to be driven and admired. The organizers of the auction estimate that it could reach a price of between 270,000 and 340,000 euros given its impeccable status and the rarity of the unit. In addition, it is equipped with outstanding characteristics for the time such as specific Speedline tires, the original interior and a mechanical configuration that makes it as shocking as it was more than three decades ago. A curiosity that shows this unit is that, when being in the United Kingdom, it has the wheel to the right. However, this was not its original configuration that the steering wheel had “in the right place“Ford modified it before giving it to its owner, and facilitated the original pieces in case you wanted to reverse the change.

We have dedicated six years to process images of a black hole to reach a conclusion: Einstein was right

by

Several years have passed since the Telescope of the Event Horizon (EHT) published the famous first image of a black holetaken in 2017. The photo has yes doquestioned by some researchersbut the EHT last year published a second image of the black hole M87*, taken in 2018. The new photo not only validated the original, but once again corroborates the Einstein’s general relativity theory. The largest radio telescope. To obtain the image of the black hole in the center of the Messier 87 galaxy, we needed to build a radio telescope about 10,000 kilometers in diameter. Since the land has a diameter of 13,000, the EHT took a more reasonable path: Extract data from different receptors, telescopes and radio antennas from all over the world and combine them by interferometry. The EHT produced 250 Petabytes of information in a one -week interval. It took a couple of years to process all the information and publish an image. But first, he added a new telescope to the project (the GLT of Greenland) and took the second image of M87* that saw the light in 2024. Six years processing. The second image of the black hole M87*, taken a year and ten days after the original, in April 2018, took six to process and publish, but it was worth it. On the one hand, proves that 2017’s observations were fine. The Persistence of the size of the central shadow In both images confirms the original estimate of the dimensions of the black hole, dissipating the criticisms about the simulations dependence to calculate this data. On the other, comparing the two images shows that the ring of matter around the black hole is rotating as expected. The brightest part has moved 30 degrees, which is consistent with the models of the hole. We are seeing what Einstein predicted. Located 55 million light years from us, M87* is a supermassive black hole in the center of an elliptical galaxy that manipulates the subject with its magnetic fields and expels the one that does not consume at speeds close to that of light. The image of 2018, like its predecessor of 2017, reflects this tumultuous activity with a bright ring around it. This validates the theory that the diameter of the event horizon, and therefore that of the black hole itself, is intrinsically linked to its mass, framing a central shadow that Albert Einstein’s equations predicted more than a century ago. Why it looks like a donut. That brilliant donut called accretion disc should be very fine, but we get very dispersed and unemployed. Throughout the trip he has made through space, his light has dispersed by the dust in interstellar space, which leads us to see it in this way. Despite the dispersion, the image is clear enough to confirm not only Black hole rotation but also the alignment of its rotational axis with a powerful stream of material (“relativistic jet”) that moves away from M87. The importance of reproducing results. Although it will take six years to arrive, this vindic confirmation the findings of the EHT and is seen as a milestone for global scientific collaboration, in addition to a robust confirmation that we are facing the shadow of a black hole and the matter that orbit it. Future data analysis will help better understand how magnetic fields and plasma flows within the accretion disc interact. In the next decade, we could even have videos of the evolution of M87* in time thanks to the next generation program of the EHT (NGEHT), which promises images of greater resolution and a broader range of frequencies. All thanks to the collaboration of observatories from all over the world. Image | Event horizon telescope In Xataka | A group of astrophysics has knocked down Kerr’s hypothesis.
