In the heat and extreme summer storms in Menorca, Aemet has just added one more risk: “Meteotsunamis”

by

A trough travels the peninsula and, like The experts advancedtheir impacts begin to be noticed today. These impacts have led to the State Meteorology Agency (Aemet) to issue various notices, Among them one focused on the risk of Rissagasthe phenomenon also known as “Meteotsunami”. Notice by Rissagas. In addition to the notices for rains and storms (which bind to notices still in force for temperatures of more than 36º in areas of Albacete and Murcia), Aemet has issued various coastal notices that will remain active during the next few days in the Mediterranean, specifically in Catalonia and Balearic Islands. Among these notices is an active one on the coast of the island of Menorca, since there are expected sea level oscillations that could reach 0.7 meters. This oscillation of the island region responds in the Balearic Islands At the end Rissagabut it is also usually called “Meteotsunami” for presenting some parallelism with the seismic phenomenon. Rissagas or meteotsunamis. As we pointed out before, the Rissagas They are abrupt oscillations of sea level. As explained some time ago Aemet’s then territorial delegate in Illes Balears, Mª José Guerrero, these phenomena occur only in coves and ports “with a certain geometry.” As with the tsunamis, these begin with the sea by backward, which can leave the small boats of the fishing and sports ports stranded. In a matter of minutes, the waters return to the port, and do so with a flood that can drag the vessels and overflow the docks. On average, these oscillations are usually about 50 centimeters. However, cases have been found in which they reached several meters. “Tsunamis“Meteorological. As its name suggests, the “Meteotsunami” differs from a tsunami in his Meteorological origin and not seismic. According to Aemetthese phenomena are produced by “small although sudden changes in atmospheric pressure (1-3 hectopascal) derived from the passage of fronts, gravitational waves, turbonada lines and in general phenomena associated with convection.” First red notice of Aemet. The forecasts speak of significant impacts beyond the risks on the coast. Aemet’s forecasts They alert today “showers and storms with a probability of being strong, even locally very strong”, which will affect large areas of Catalonia, Pyrenees, northern zone of the Valencian Community and east of the Iberian system. Tomorrow these showers and storms are expected to affect both the Mediterranean coast of the peninsula and the Balearic Islands themselves. Thus, the agency has issued notices of different categories distributed throughout the center and northern Mediterranean slope and the Balearic Islands. Today’s notices include a red notice (extreme risk) due to rains in the central depression of Barcelona. In that area, up to 60 mm of rainfall could be accumulated in one hour and up to 120 mm in a matter of three or four hours. Waiting for a change. In addition to the red notice due to extreme risk, the agency maintains various orange notices (for important risk) during today’s and tomorrow, both for rains and storms. The situation is expected Start to appease on Fridayalthough some episodes torments are expected to continue during that day.

What is seen at the bottom of the map is an extreme anticyclonic dorsal. And that is what is going to put Spain again to boil

by

It is a story that has been repeated from the beginning of summer: an anticyclonic dorsal will dominate the atmosphere on our heads, which in turn implies the return of heat. The return to 40º. The next few days will be, again, of extreme heat. The State Meteorology Agency (Aemet) has warned of temperatures that They can exceed 40º in large areas of the South and that could also reach 42º in specific areas of the Peninsular South. An extreme dorsal again. The person responsible is a dorsal, and a considerable magnitude: 600 DAMMERS (DAM) Geopotential with the center located in North Africa. This means that we have to ascend about six kilometers in the atmosphere before reaching the point where the atmospheric pressure is 500 hectopascal (HPA), when the “normal” value of this altitude would be around 5.5 km. Although the geopotential in most of the peninsular Spain is rather something above the 594 DAM, this involves “record” levels for this time of year in the southwest peninsular quadrant and part of the center, indicated on Twitter The physicist, meteorologist and disseminator JJ German. Stability and sun. The dorsals They imply An anticyclonic context that in turn entails stability and clear skies and high insolation. If we add its ability to drag air from North Africa and its recurrence we will see with a situation like this, a summer that has already served to break numerous records in temperature and other atmospheric variables. Yellow and orange warnings. Temperatures may not reach the levels of previous warm episodes, and the fact that we are already in July (one month on average warmer than June) implies that this geopotential anomaly will not translate into large anomalies. Despite this, mercury will rise enough to Aemet activates various notices associated with extreme temperatures in much of the country between today and Thursday. The orange notices between today and Wednesday will be concentrated in areas of the center and southwest peninsular: Valleles del Tajo, Guadiana and Guadalquivir, especially. On Thursday, extreme heat will also affect the East, with part of the Ebro Valley, La Mancha Albacete and the interior of some Mediterranean provinces under orange warning. High maximums and tropical nights. The agency’s prediction For these days they talk about temperatures that “will exceed 38-40 (Grada) in large areas of the southern half of the Atlantic aspect” tomorrow Wednesday, with areas of the Guadalquivir Valley, being able to exceed 42º. The forecasts for Thursday will be somewhat less extreme, although the 35º will be exceeded in most of the southern half and in the northern plateau. As if this were not enough, the minimums will also remain high: large areas of the south and the Mediterranean basin will see how mercury does not fall from the 20º. Again the Guadalquivir Valley would be the most affected Peninsula area: the minimum could stay here above 25º, that is, we could see the return of the “Equatorial nights” Change of trend. For now, the dorsals have alternated with tormentous episodes driven by vaguadas, danas or other phenomena associated with a low pressures zone. This week the pattern will be repeated with a thermal relief that will arrive on Friday, accompanied, yes, storms that already concern some experts.

Aemet at last at the end of the extreme heat tunnel in Spain. The only problem is what comes in place

by

During the last weeks, the successive hot episodes (including the heat wave at the end of June and early July) have alternated with the arrival of vaguades that offered a certain thermal relief. A relief loaded with storms and hail, but relief after all. However, the dynamics of recent weeks seem to have broken. Postbile Dana. Meteorological models foresee the possible formation of a DANA, an isolated depression at high levels. This phenomenon, Experts of Meteoredthis phenomenon would bring more hailstorms in addition to winds of consideration. Two masses of air. The arrival of the Dana would also occur in a context also different from what we had seen in a June where the heat was extended by almost the entire peninsula. The first days of this are mana are characterized however by A two -speed Spain: With a mass of cold air installed in the peninsular north and a warm air dominating the center and the south. The long -awaited thermal relief is therefore produced at two veliocities, more quickly in the north (where temperatures have already moderated) and more slowly in the south, where the thermometers will move away from the 40º mark but with a slower stabilization. Uncertain weekend. That would be the context in which Dana could make an appearance. There is still uncertainty about how the “Descolgue” of this area of ​​low pressures will be and its entry into the Peninsula, but the simulations indicate that the arrival of this phenomenon will occur between Friday 11 and Sunday 13. More storms, more hail. This leaves us a panorama of uncertainty for the end of this week: if this arrival of the DANA occurs the instability could be high and that means that we could see a new rough storms with rainfall and strong winds. According to the modelsSaturday will be the day when it is noticed in our environment. According to these same models, the most affected areas will be the north third, the northeast peninsular and part of the Mediterranean coast. A summer of uncertainties. The question now is to know what will happen after this week of relief. While the warm episodes of the last month and a half had been interspersed for days of storms and temperature reduction, these stops in the thermal escalation had been rather brief. This week however the arrival of several troughs, including an associated with the possible Dana could involve a somewhat more marked reduction in temperatures. For now it is soon to know what will happen. The Monthly prediction From the State Meteorology Agency (AEMET) points out that we still have hotter weeks than usual for these dates, between 3rd and 5th warmer than the average. The quarterly forecasts Aemet also indicates that we have several warm months ahead: 70% probability that it is.

habits and tricks to sleep under an extreme heat wave

by

During a heat wave it is common for us to put our focus on the scorching maximum temperatures. However, this is not the only indicator that warns us of the problems that we must face during this type of episodes, minimum temperatures can be so important or even more in some circumstances. The “tropical nights.” According to it The State Meteorology Agency (Aemet) before the start of this heat wave, one of its characteristics would be that of the Tropical nights. This term refers to those nights in which the minimum temperatures do not fall from the 20th Celsius. The forecasts They talkedin fact, of minimum temperatures that could exceed 25º, nights to which a different term is applied, that of “Equatorial nights”. Already before the entry into force of the agency’s special notice on the occasion of the heat wave, some areas of the South such as Seville or Almería (but also in other areas such as Girona) They registered minimal Above this 25º barrier. Why is it so difficult to sleep? There is a close relationship between body temperature and sleep cycles. The hours of sleep our body temperature is usually faster than during the day, but the descent in body heat usually starts before we sleep. Even before we lie. The problem arises with the arrival of excess heat. Some scientists theorize that with heat It can happen as with lightwhich would be used as a reference by our body to distinguish the night of the day, the hours to dedicate to the dream of vigil. If it is hot, or if there is light, our body interpretter that is not yet time to go to sleep. The tools in our hand. The simplest option is to plug a fan or keep the air conditioning on all night but this is not always an option, either because we do not have any of these devices, to avoid scares when paying the electrical invoice or, even, because they are not options too convenient for our health. So what can we do? If heat is like the light that prevents us from reconciling sleep, a simple strategy is to isolate ourselves from it as we isolate ourselves with light. We can start by choosing an isolated room, away from the facades, oriented to the north and not to the south, or far from the upper plants if we live in a house with more than one plant. To maintain this fresh room, it is convenient to ventilate it, but not expose it to the entry of light, also avoiding artificial light sources and heat sources such as burning or mobile computers loading. Cool Maintaining a fresh sleeping environment is important, but maintaining our own fresh body is too. The strategies that we would conventionally use to refresh ourselves, even those that are contraintuitive, can be of great help. Avoid what can increase our body temperature during the afternoon, such as especially hot meals or physical exercise can also be useful. “Sleep hygiene.” Sleeping during a heat wave is especially difficult but sleeping strategies better that we use conventionally can also help us. In this sense, correct sleep hygiene can be helpful in these cases as in others. Habits such as maintaining regular schedules, or avoiding screens and lights before bed are usually among the usual recommendations in this regard. An active life and healthy eating can also help us fall asleep better, even in conditions like these. The heat wave ends, but … The forecasts indicate that temperatures will fall during the next few days, being able to conclude the episode the day after tomorrow. However, we are only at the beginning of summer, a summer that has started intense but whose evolution is for now uncertain. The tropical nights have been accompanying us for weeks and probably keep doing it during the summer. These can be aggravated by situations such as the current one, but in themselves they are not a rare phenomenon in the summer (although it is likely to become more and more frequent). Adapting to them is therefore important if we do not want to sacrifice our rest for several months a year.

The atmosphere has been stuck in a “extreme heat generator” on Spain. That means something: a hard summer

by

The first fortnight of June has brought us more typical temperatures at the end of July or even August: there have been numerous days in which wide areas of the southern peninsular have seen the thermometers exceed the 40º line. The problem now is not that heat stays with us throughout the summer, the problem is that it may go more. Same trend. The heat seems determined to settle on the peninsula, or at least that is what can be detached from models such as those used by the European Center for Middle Term weather forecasts (ECMWF). To understand why, we have to look higher towards the atmosphere. About 1,500 meters high. According to Explain The physicist, disseminator and researcher at Aemet JJ German in his account Twitterwe have the track in the forecasts on the temperature at height at 850 hectopascales (HPA), which usually refer to an approximate height in the atmosphere of 1,500 meters, the low troposphere zone. The temperature at this level tends to be related to the temperature that we see at soil level, so it can serve as a reference for how temperatures will evolve in the coming days. According to data shared by German, we not only find a temperature above the climatological average (an anomaly above the 5th Celsius), but the situation will last, with the possibility that this anomaly approaches 10th towards the end of June. “This is barbarity: far from returning to balance as normal, atmospheric dynamics on the Iberian Peninsula seem to get stuck in an extreme heat generator,” explained in its publication. Looking at the map. If we focus on The map Prepared by ECMWF, we will also see that heat will remain foreseeably installed on our heads. The forecasts indicate that during the next ten days the almost entire peninsula will be under the influence of temperatures above 20º to 850 HPA, with large areas above the 24th and with some points, the 28th barrier temporarily exceeds. What’s happening. In a second TweetGerman explained what is happening. According to the expert, a Dana located west of the peninsula and a dorsal (an extension of high pressures associated with an anticyclone) would be responsible for the situation. A situation that would be seeing aggravated by the low atmospheric movement, thus achieving what German refers as a “static equilibrium point.” The result: heat and more heat. The result is the intuitive: this warm episode seems to be sentenced to extend over time, at least during the next week. The maximum in a large part of the Peninsular South They could stay above 36º and promptly above 40º.

France is the most radical country against technology among children. And now it plans something extreme: prohibit social networks

by

“We must ban social networks to children under 15 years.” This blunt was the French president, Emmanuel Macron, speaking before the TV cameras. The measure It would be a pioneer In Europe, which studies initiatives in this regard, but there is a problem: France’s regulatory role is having negative consequences For companies and users. What happened. The statements of the Gallic president occurred after the Tuesday tragedy In a French school: a 14 -year -old boy stabbed and killed a member of the teaching staff. As they point out In EuronewsIt is not clear if this attack is associated with something that the teenager had seen on social networks. No knives. Macron intends to prohibit social networks to children under 15 “in the coming months” if there is no progress in a similar regulation at the European level. The tragedy in Nogent’s greate Indian that “a 15 -year -old can no longer buy a knife on the Internet. That means we are going to impose massive financial prohibitions and sanctions.” And either of social networks. But the highlight was that intention to ban social networks, something that even announced in X said intentionIn addition to stating that platforms have the possibility of verifying age to be able to implement this type of control and prohibition. Actually the message is not new: said exactly the same thing more than a year agobut the recent events and European inaction have re -promoted those intentions of Macron. They are already doing it with porn. On June 7, the law that forces pornographic platforms to verify age of users. The objective, prevent minors can access this type of content. But it is not going well. As a consequence of these measures, services such as Pornhub, Redtube and YouPorn have decided to leave the Gallic country and stop serving there. According to those responsible, this regulation is inefficient and potentially violates users’ privacy. Also propose a solution Device dependent and in which Google and Apple would have to make some modifications to their operating systems. The struggle of minors and screens. France was a pioneer in 2018 when prohibited mobile phones in schools for students under 15 years. Other countries They followed the wake, but the country continues to alert the dangers of the screens for the minors. In fact, a process was recently initiated to try prohibit the use of any screen (Mobile, but also TVS or computers) to children under six years. According to French experts In pediatrics or child psychiatry, not doing so exposes them to permanent damage to brain development. Spain, in the line of France. In our country the future law of the minor advocates Prohibit registration on social networks of children under 16 yearsclimbing the current limit two years. There are also measures to limit access to technology according to age, and for example from zero to three years the use of children should be prohibited from children, while from three to six years it is advisable except exceptions and under the supervision of an adult. The Spanish “pajorto”. The Government of Spain also launched a year ago The implementation of the Beta Digital Portfolio, popularly known as “Pajorte”. It is a mobile app that will theoretically serve to perform age verification and thus avoid or mitigate access to pornographic content by minors. Its implementation is limited, although the platforms that are already implementing it have detected A colossal fall of its traffic. Europe begins to move card. As they point out In politicianthe European Union has raised a proposal led by Greece and France and Spain as great support. In it the objective is to establish a new regulation to significantly limit the use of social networks by minors. According to the project, minors could lose direct access to networks Like Tiktok or Instagram and would need parental permission to visit these platforms. Denmark, which will occupy the presidency of the EU in the next six months, is in favor of these measures Image | Anthony Choren | Mary Borozdina In Xataka | There were two paths to regulate technology in children: the government has chosen the one with zero screens

Aemet emits the first orange warnings by extreme temperatures

by

A few days ago, meteorologists They foresee that the worst of the warm episode that affects the Iberian Peninsula would come from Wednesday. Well, we are on Thursday and the forecasts become facts: the “Iberian oven” has activated and with it preventive measures. Orange warnings. Heat has led to the State Meteorology Agency to issue A series of yellow and orange notices by maximum temperatures. Today’s notices will affect seven autonomous communities, tomorrow Friday to nine. The Sevillian countryside will be the most affected area, where notices will be oranges due to maximum temperatures of 40º Celsius. Oven ignition. The obvious question is what is happening for the sudden arrival of more typical temperatures of summer than at the end of May. The answer can be found in the phenomenon known as “Iberian oven” As details Marta Almarcha in eltiempo.esthe phenomenon begins with the appearance of a dorsal in middle and high layers, that is, in the prolongation of a high -pressure center. This implies atmospheric stability and air -descendant movements that compress and heat the air mass over our own heads. More than an anticyclone. Anticyclonic and stable time also contributes to a High insolation which in turn also implies heat. As if this were not enough, Aemet warned a few days ago of the irruption of a Dana located between the Canary Islands and the Gulf of Cádiz that since yesterday pushes warm, dry and with dust in suspension to the peninsular south. Heat, very heat. The result, the one that is well palpating: heat. According to them Aemet forecaststoday maximum “high temperatures are expected for the time in most of the Peninsula”, with areas of the South exceeding the 34º-36º and with the possibility of exceeding 38º-40º in the Guadalquivir and Guadiana Extremadura. The story will be similar tomorrow Friday, with high maxims, possibility of exceeding 34º-36º degrees in the southern Atlantic aspect and the 38º-40º in the Guadalquivir, but without ruling out that the thermometers also reach this temperature at points of the Guadiana and depressions of the northeast. On Saturday a similar situation will be repeated as far as the maxims are concerned. Tropical nights. In addition to the maximum, the minimum temperatures also concern many. The fact that night temperatures They are not going to get off the 20th In some areas the dream of many will make it difficult. This is the phenomenon known as “tropical nights.” Spring activation. It is not the first time that we see this “Iberian oven” be activated in the middle of spring. In 2023 without going any further We were talking of its possible activation at the end of April.

How many books a month are too many books? The debate about reading as another form of extreme consumerism

by

The mixture of the need to create constant content and the search for new forms of validation has generated a new controversy in the Tik Tok literary sector. Creators cross accusations with others about the legitimacy of reading without stopping, where is the real enjoyment and if reading more or less determines the real quality as a reader. They have not reached any conclusion, but the question is on the table: how much do you have to read to read good? Readers shock. The booktoker Beautifulone of the most often of the Spanish booktokersfera, with almost 350,000 followers She was accused by another booktoker, Palomo Gamyito erroneously normalize reading dozens of books per month. According to this other Booktoker, this infernal rhythm of readings hides a much more critical reality: we must maintain that rhythm of readings to follow the crazy rhythm of launch of the great publishers, accusing many of the main creators of content about books of being spokesmen at the service of the industry. 11 tricks to dominate Tik tok What this clash hides. Gamyi is, in fact, a booktoker who instead of talking about the Latest novelties of Romantasy and literature Young adultcomments more serious novels, such as ‘The Shadow of the Wind’ or ‘The Conjure of the fools’. In addition, it combines comments from books with videos about your own love for writing. His defense of reading little but “better” also hides an ethical positioning and a claim of gourmet readings above literary fast food. Where everything is kneaded. All this happens in the BookTook digital subculture, an increasingly numerous group of users that recommends and promotes books: from recovery of classics to comments from novelties, going through tricks to read more and/or better. Many observers believe that this current our way of reading has changed and is transforming The customs of generation Z. He Hashtag that Group these users It already adds 200,000 million visualizations, enough to consider a cultural force that conditions the large publishers, who see how gender sales like Romantasy rise when recommending them Booktokers. What have the booktokers have done. Convert the accusations of Palomo Gamyi into a viral issue, of course: it has been put on the table how many books it is reasonable to read a month, all overlooked with tips and humor. It is an issue that was already commenting Since 2024so it is not new, but the video of Palomo Gamyi has brought up what this activity has to follow the editorial rhythm together. That is, a matter of creation of novel content to grow in social networks. Too many books? From this conflict two primary themes come out. The first is whether in Spain they are published Too many books: In 2024 were 89,347according to the Ministry of Culture: an increase of 2.6% compared to the previous year already levels similar to the pre-pondemic years. It is a very high figure and puts us at the head of Europebut it generates problems: a fierce competition for the care of the reader and a very short life for the news. A problem that, perhaps, compulsive readers such as beautifulbooks are helping to prolong. A validation. The other problem of the Booktoker community that hides this conflict is the search for personal validation through quantity, something similar to Likes psychology: A reaffirmation is sought through that acceptance of strangers. The mountains of read books are also a way of generating admiration and envy by a community with which tastes are shared, no matter how much reading is not very repossed and, as Gamyi complaint, does not generate a real reflection on the work, but a mere to pass pages. The discussion has not caused the blood to the river, and most of the booktokers participating in it seem to agree that each one must read what he can (and want). Which does not prevent a long and sinister shadow on such a simple and, beneficial hobby, benefit, such as reading for pleasure. They are also readers. The BookTokers They are not a promotional creation of the industry, but a spontaneous movement born in social networks (they have their equivalents in others, such as Booktubers), and they are a sign that in post-pandemic reality, there is a generalized fever by reading. Microeditorials arise consecrated to the publication of authors and projects outside the great industry, reading clubs They have ceased to be an extravagance For library mice, and books are relief from the saturation of screens we live, even in our leisure times. Conflicts like this are the least, because in the end they refer to the important thing: we like to read.

Mr. Beast has brought his extreme tourism videos inside the Mayan ruins in Mexico. That is a problem for ruins

by

Mrbeast It is the most important youtuber and followed in the world, and virtually any idea it has to generate content in its channel becomes a trend. Millionaire contests, spectacular challenges, philanthropic maneuvers … and now, adventure tourism. One of his last adventures has been to pass One hundred hours in an old Mayan temple two thousand years old. It is an idea with a peculiar dark side. One night in the temple. In the video we can see how Mrbeast wanders inside several Mayan pyramids, among other Chichén Itzá. Accompanied by an native guide, which reinforces its promotional character for the powerful tourism business in Mexico, sleeps in the jungle, and can touch funeral masks of the kings buried in the area. A privilege that is not at the scope of any tourist. A superstar. With almost 400 million followers and more than 82,000 million visualizations, no one doubts that Mrbeast is The most important youtuber in the world. The average video display on its channel is about 100 million, although it already has many exceeding 200. The income of your channel They can exceed four million dollars, not counting sponsorships or agreements. An authentic icon of the platform that is largely responsible for the spectacularization of Influencers: Always looking for the most extreme challenge, the most shocking image and the most unexpected trip. The spectacularization of YouTube. This spectacularization of the content is very clear in the titles of its last videos: ‘Would you risk drowning for $ 500,000?‘, I survived 7 days in an abandoned city, I survived the 5 most mortal places on earth… It is a radicalization of the content that is not only in the subject, but in the visual: climbing assemblies, a lot of noise and screams, many careers, a dynamic that stuns and that Keep the spectator dopamine by the clouds. Extreme tourism. Mrbeast exploits a new form of telematic tourism that is hooking millions of viewers by making these trips to remote places, often giving them an adventurous narrative: these trips are often linked to extreme challenges or tests, and have turned tourism into an experience that can be digitally consumed. For example, a few months ago we talked about Fabio Belnome and his trip in a 1998 Fiat to Japan. But there are many more in different social networks: the mountaineer @Nimsdaithe urban explorer @Shieyfreedom or the traveler to high -risk countries @drew_binsky. Thanks to them, the hashtag #tikToktravel, for example, has More than 23,000 million views. The dark side. However, there is a dark side in videos such as Mrbaest Chichén Itzá. In 2024, the Secretariat of Tourist Development of Yucatán reported that he expected the arrival of 6.7 million tourists, more than double those that arrived in the last year pre-pandemic. It is an area to which tourism provides 90% of its income. The controversial Mayan train. To promote and facilitate tourism, projects such as Mayan traina transport that will travel relevant areas of the Mayan zone, with special attention to serve tourism, connecting airports in a space of 1500 kilometers. But the authorities are concerned about Environmental impact of the pharaonic López Obrador project. For example, the works have been arrested in the area of ​​the Riviera Maya, one of the most frequented by tourists. The impact is more than studied in what affects caves, temples and other protected areas, and Even Unesco has intervened. The double track. Mexico is, in this way, before a dilemma: the content of Mrbeast is sponsored, as the video credits affirm, by the Tourism Secretariat of Mexicoin collaboration with institutions such as the National Institute of Anthropology and History. But at the same time, the massification of tourism is eroding archaeological treasures such as these temples, in a dilemma of which perhaps the great travel and adventure youtubers will have to begin to take responsibility in the future.

The extreme temperature in which the laws of physics we know stop operating

by

The absolute zero marks the minimum temperature at which something can be found and corresponds to -273.15º Celsius, or 0 Kelvin. Since heat is nothing other than movement, this temperature marks the total stillness, but what happens at the opposite end? Planck temperature. Although we are less familiar with the other extreme, Planck’s temperature, or the “absolute heat”, Another concept managed by contemporary physics. Here we might make emphasis on” contemporary physics “since, at this temperature, what we know of physics stops operating, which leaves us in an unknown terrain. How much heat are we talking about? Well around 142 quintillones Kelvin (K). Or what is the same, 1.42 · 10^32 degrees Celsius: the 273 degrees of difference between both scales are inconsequential on this scale. As a comparison, we can point out that the estimated temperature of the core of our sun is about 15 million Kelvinalthough the remnant nuclei of some supernovas can reach the billion degrees. Here on Earth, science has achieved even higher temperatures: More than 5 billion Kelvin in an experiment conducted in 2012 in the Great Hadron Colliding (LHC) of CERN. Defining the maximum. We indicated before the absolute zero in temperature was marked by the lack of movement, the absence of thermal energy. The temperature is an energy transfer measure, if something has no energy, It cannot transmit it. However, to find absolute heat we must go beyond thermodynamics and incorporate another area, that of quantum physics. To understand this limit, we must know that heat is associated with emissions in the electromagnetic spectrum. At more heat, more energy, shorter will be the frequency in this spectrum. Well, this spectrum is not infinite since the known universe has its own minimum distance, Planck’s distance. This minimum length Mark too The shortest wavelength and the maximum energy that we can introduce into a photon. It is therefore impossible to transfer more thermal energy. A rather theoretical idea. Planck’s temperature remains, as we pointed out before, far from both what we can see in the universe and what we are able to recreate in a laboratory. There was a time when it may not be so, since in the first moments after the Big BangThe universe would have reached this type of temperatures. But precisely the Big Bang It is one of those contexts in which the laws of physics as we understand them are not applicable. Beyond contemporary physics. The Big Bang is a clear example that there is physics that still escapes us, as are black holes. In both cases these are contexts so extreme that the description of what happens in them through the laws of physics we handle makes it impossible. However, we continue in the search for knowledge about these extremes and the laws that could operate on them. Probably, the long -awaited “theory” of all that unifies what we know about relativistic gravity with quantum physics can give us important clues about this border of heat and, above all, what may be beyond this.
