A study rises to 90% the probability that we see a black hole exploit. Physicists have become nervous

At some point in the next 10 years we are probably witnessing the explosion of a black hole, according to a new model published in Physical Review Letters. In the light of the telescopes, this very powerful event has the potential to confirm the most famous theory of Stephen Hawking and give us a catalog of unknown particles of the universe. Short. A team of theoretical physicists of the University of Massachusetts Amherst It has recalculated the probability of seeing live the violent explosion of a black hole under the assumption that there are primary black holes in hibernation. Its conclusion is that the most potentially transformative event of modern cosmology could be just around the corner: they calculate more than 90% possibilities that we witness the explosion of a primary black hole during the next decade, under the assumptions posed by the model. The Fat Prize for Physics. Seeing a black hole would be transformer in at least three fronts. It would be the first direct observation of the Hawking radiationthe famous theory of 1970 with which Stephen Hawking postulated that black holes losing mass slowly emitting particles, so they are not completely black. In addition, it is believed that A black hole in evaporation emits all fundamental particles whose mass is lower than its temperature. Therefore, the explosion of a black hole should reveal from the electrons and quarks that we know, to hypothetical particles of dark matter and others completely unknown to science. Finally, the event would confirm the primary black holes. Unlike the black holes that are formed by the collapse of mass stars, it is believed that the primordials were formed in the extreme conditions of the universe less than a second after the Big Bang. “I would completely revolutionize physics and help us rewrite the history of the universe,” says Joaquim Iguaz Juan, co -author of the study. How a black hole explodes. The idea that black holes can explode directly derives from Hawking radiation. The theory says that the lighter a black hole, the higher its temperature and faster emits particles. This creates an uncontrolled process: as it radiates, loses mass and heats up even more. Consequently, it radiates at an increasing rate until, in its final moments, it fades into an explosion of high energy radiation (mainly gamma rays). The problem is that, until now, physicists believed that the chances of seeing such an event were infinitesimal. These calculations, based on black holes without electric charge (black schwarzschild holes), suggested that explosions occur, at most, once every 100,000 years. With those chances, we would have to be very lucky to see one. Where that 90% probability comes from. The researchers decided to question the departure assumption: what if the primary black holes are not electrically neutral? The new hypothesis proposes the existence of a force similar to electromagnetism, But in the dark sector: With a “dark photon” and a very heavy “dark electron”. If a primary black hole was formed with a small dark electric charge, its destination would change completely. This mechanism works as a brake. As the black hole loses mass due to hawking radiation, its load/mass ratio increases, causing its temperature to drastically, which submits it to a state of hibernation for billions of years. After that time, the dark electric field near the horizon becomes so intense that he discharges the black hole, causing the final explosion that we have been waiting for. Why does this increase the chances of observation? Because this long stability period allows much lighter black holes (and, therefore, much more numerous) survive to this day. A greater number of nearby candidates drastically increases the local explosions rate, passing from one every 100,000 years to one every 10 years. We have the technology to see it. The best part is that we do not need to build new technology. Gamma ray observatories as Hawc in Mexico And Lhaaso in China are already scanning the sky and are perfectly able to detect the outbreak of a nearby primary black hole, at a distance of up to 0.3 light years. “We already have the technology to observe these explosions, so we should be prepared,” says Michael Baker, lead author of the study. If it happened, it would be a historical moment. We would be seeing, for the first time, the final echo of the creation of the universe, a first look at the most fundamental secrets of the cosmos in a single and spectacular outbreak of light.

The University of Oxford has found reservations of an energy source for 170,000 years. And he has the recipe to exploit them

In a world that seeks to leave behind fossil fuelsthere is a gas that has begun to be outlined as the promise of A clean future. Its potential as an inexhaustible source of Green energy It has aroused both enthusiasm and frustration: producing it without contaminating is still expensive and technologically complex. However, a group of scientists could have found the key to hydrogen under our feet, from the very depths of the earth. Clean gold underground. We have told it On other occasions. Hydrogen has been long promoted as a key piece in the transition to a future without emissions, but also as an essential resource for modern life: in addition to being a clean fuel, it is indispensable for produce fertilizers that support half of the world’s population. The problem? That 99% that is used today It comes from hydrocarbonswhich represents around 2.4% of global carbon dioxide emissions. With a projected demand of 90 million metric tons in 2022 to some 540 million in 2050the challenge is monumental. Until now, cleanest solutions (Like electrolysis with renewable energies or carbon capture) have failed to be economically competitive. Here appears the new Oxford study Posted in Nature: The earth could have solved the problem for us millions of years ago. An unexplored reservoir. In this way, Oxford researchers together with professors at the University of Durham and Toronto have revealed that the continental cortex of the Earth has generated, throughout the last geological millennium, sufficient hydrogen amounts to supply the energy needs of humanity For at least 170,000 years. This immense reserve, natural and emission free, remains largely trapped undergroundintact. Although until now the measurements were sporadic and scattered, the New job It offers for the first time a coherent framework, a “map” if you want, to locate these reservoirs: a “Exploration recipe” (They call it) that details the types of rock, temperatures, fluids and geological conditions necessary for hydrogen to form, migrate and be trapped in exploitable deposits. The approach is not theoretical: it is designed to guide the commercial search for natural hydrogen globally, with the potential to radically transform existing energy models. Ingredients, processes and threats. Such as Professor Chris Ballentine explained in a statementleader of the study at the University of Oxford, finding hydrogen in the earth’s crust is like baking a sufflé: if one fails in any component (quantity, temperature, time or type of rock), the result will be useless. The study Identify the factors that allow a geological hydrogen system to be viable: from the chemical reactions that generate it, to conditions that destroy itlike the presence of certain underground microorganisms that feed on it. This biological threat, indicated by the co -author Barbara Sherwood Lolar, forces to avoid areas where underground bacteria can consume hydrogen before it can accumulate in usable concentrations. Ubiquitous, diverse and list source. There is much more, since The work It also disassembles previous myths on the origin of hydrogen, discarding as unfeasible the sources from the mantle terrestrial and focusing attention on common formations of the continental cortex. These can be both recent (of some millions of years) as an eldest, and are distributed globallywhich greatly expands the geographical exploration potential. Plus: the crucial, They sayIt is not to find a specific type of rock, but to understand the interaction between the chemical, thermal and historical conditions that favor the generation and storage of gas. From theory to action. Aware of the strategic value of their findings, the authors have founded the Snowfox Discovery Ltd.a company dedicated to locating natural hydrogen reserves with social impact. Its objective is clear: to find competitive, clean and sustainable sources of hydrogen, capable of replacing highly polluting current production and feeding the global energy transition without the need for expensive industrial processes. Yes Geological recipe Developed by these researchers, it can be repeatedly repeated in different regions of the planet, we would be facing the closest to an energy revolution … underground. One that does not require new futuristic technologies or dreams of merger, but simply learn to hear THE SECRETS THAT THE EARTH He has been whispening For hundreds of millions of years.

In his second trailer, ‘Gta VI’ aims to exploit one of the great ideas so far absent in the franchise: love

Although it sounds strange at this point, the Second trailer of ‘GTA VI‘points to something unexpected: Rockstar has matured. Or at least, he intends to continue with his purpose of making games more adults than those who gave him fame, an intention that started with ‘Red Dead Redemption 2‘. For the first time in the franchise, we see unthinkable maturity notes a few years ago. Hello to love. The plot core of ‘GTA VI’ will undoubtedly be the love story between Lucia and Jason, something unusual in a franchise full of promiscuity, prostitution, unsatisfactory marriages and lonely antiheroes and without time for love. This is what Rockstar tells us in the official synopsis: “Jason and Lucia always knew that the letters were against them, but when a blow that seemed easy to go wrong, they are trapped on the darkest side of the most sunny place in America, in the midst of a criminal conspiracy that extends throughout the state of Leonida, and forced to depend more than ever of each other if they want to go out alive.” Goodbye to the cartoon. If something puts on the table the new trailer of ‘GTA VI’ is A graphic realism never seen in the serieseven though we could be talking only about kinematics. And that realism has to bring hand in hand A change in the arguments that develop. Let us remember what the characters of ‘GTA III’, ‘Vice City’ or ‘Liberty City’ were: excessive, big heads, of schematic movements, almost cartoons. That has ended, and emotionally, the characters have to live up to it, in the same way, as we pointed out in their day, The demands of female representation have changed. A clear inspiration. Before we know more details about the argument (there are already rumors that Jason It could be an undercover policeman), the clearest reference of GTA VI are Bonnie Parker and Clyde Barrowthe couple of robbers of banks who lived a bloody romance in the Chicago of the thirties. In this trailer we see Jason and wore a bank together, the first picking up the second when it comes out of jail, and sharing some beers, a sunset and some passionate scenes that perspire a certain unusual tenderness in the ‘GTA’ games. But a shadow looms on them. The thing may not end well: Rockstar games, especially the recent ones, usually deal with betrayal, one way or another. In ‘GTA v‘, where we were driving alternately to the three protagonists, in the end we were asked to choose between betraying our classmates or accepting a last mission with them. In ‘Red Dead Redemption’, betrayal when the protagonist seemed to have reached peace was inevitable. And in this ‘GTA VI’, if we alternately control the protagonists in the ‘GTA V’ style, the player could have to resort to a similar decision: loyalty to his partner or fulfill a mission. The model is ‘Red Dead Redemption 2’. It is the most sophisticated and deep game at the level of characters that has set rockstar to date. He left behind the grotesque composition of the protagonists of ‘GTA V’ and opted for emotion: in ‘RDR2’ we see Arthur Morgan learn with the player valuable lessons about betrayal, responsibility and – while he faces his own death, and as it is inevitable taking into account the title of the game – redemption. If Rockstar looks for a reference for maturity and adult characters, his own masterpiece is his model. A logical trajectory. From ‘Red Dead Redemption’, published fifteen years ago, the detour to more mature and adult arguments is indisputable. He was followed by the police key ‘La Noire’, the turn of ‘Max Payne’ in its third part towards personal hells and the second installment of ‘Red Dead Redemption’. Only ‘GTA V’ and, obviously, the verbenero ‘GTA online‘, to which you have to feed apart, they have left that line. But even recognizing that the fifth installment of the franchise is a look at more frivolous and caricaturescos times, posed unprecedented issues and approaches in the criminal saga. For now, noise and fury. For now, all this are conjectures, such as The brilliant idea that all we are seeing is the start of the game and Jason dies in the early hours of history. We cannot deduce from the second trailer what are going to be the key points of the argument, but the official information makes it clear that the relationship between Lucía and Jason (include or not deaths, betrayal or something else) will be openly romantic. And what is clear from the tone and visual style of the trailer is the potential of the game of giving an unprecedented impulse to the depth of the stories that are told in video games. And Rockstar is not known for letting this type of opportunities pass. Header | Rockstar In Xataka | The delay of ‘GTA VI’ goes far beyond a mere change in the calendar. It is an earthquake for industry

France is installing turbines under the sea to exploit the renewable energy source that never ceases: the tides

In the heart of the sea, where the powerful tidal currents move to the rhythm of lunar gravity, an energy revolution is being created that promises to transform the future of Europe. France has a continuous energy with a large -scale installation. The project. French company Normandie Hydroliennes has created The NH1 initiative to generate energy from sea currents. The installation will consist of four seniomotor submarine wind turbines that will be located in the Raz Blanchard, a sea step known for its currents. The great support. EU 2023 Innovation Fund He has subsidized to the project with 31.3 million euros. In this way, Europe expects to integrate tidal energy into the energy mix in France and Europe, adding a constant and predictable source to avoid Intermittent energy problems. The largest in Europe. Thus it will be thanks to the AR3000 turbines, which are considered The most powerful in the world in the mareomotor energy sector. Each turbine will have a 3MW power and a 24 -meter rotor diameter and, its advanced control system will constantly adjust the speed and angle of the blades to optimize the production of electricity. It should be added that the marine structure of these turbines allows them to be installed in just 20 minutes. Stable energy. An interesting small fact is that this type of renewable energy offers a stable and continuous supply, thanks to Natural forces as the lunar gravity that generates the tides and moves the oceans continuously. Energy sending. The energy generated by the turbines will be transported to the ground through a single export cable, which facilitates the connection of multiple turbines to transmit the electricity generated efficiently. This type of very demanded cables in Europe It has made effective The network connection between England and Denmark, among other projects. However, too It has been target of objectives In geopolitical conflicts. The occasional setback. Like any type of large -scale system, problems may appear. The company has indicated that the design of the project minimizes the environmental impact and reduces costs, but problems may arise due to the extreme marine conditions of the sea pass. As for the marine impact, problems may arise of local fauna and flora. Forecasts. From the French company have indicated which will provide 34 GWh per year to the France electricity network from 2028. In addition, they have estimated that this energy source has a potential of up to 100GW by 2050, supplying the electrical needs of 94 million homes throughout the continent.
