sound

Some astronomers analyzed the “Big Bang sound.” Now they believe that the Earth is in a vacuum of 2,000 million light years

by

Cosmology has a huge problem. It is known as hubble tension and suggests that the nearby universe is expanding faster than the distant and primitive universe He is telling us. Something does not fit. Now, a disturbing study offers a solution. The big problem of cosmology. Hubble tension is One of the biggest headaches of modern physics. On the one hand, we have the measurements of the cosmic microwave background (CMB), the oldest light in the universe. When applying the standard cosmological model (LBDACDM), these observations show a 67.4 km/s/mpc hubble constant. On the other hand, when The expansion of the universe is measured Using nearby objects such as standard candles (a type of supernova), a significantly higher value is obtained: about 73 km/s/mpc. This difference, that the most recent data places in a tension of more than 5Sigma (a level that in particle physics is considered a discovery), refuses to disappear. A disturbing explanation. A new study Prepublished in Arxiv proposes a solution as elegant as depressing. That the discrepancy is not in our measurements, but in our location. According to Indranil Cosmologists Banik and Vasileios Kalaitzidis, we could be living in the center of a gigantic cosmic vacuum, a “bubble” of 2,000 million light years in diameter with a density 20% lower than the universal average. The test, they affirm, It is in the “Big Bang sound”. A local vacuum. The idea of the local vacuum is not new: it is known as the empty KBC (Keenan-Barger-Cowie, in honor of the astronomers who proposed the idea based on the galaxies count). If our galaxy, the Milky Way, were in a region with less matter than normal, the severity of the surrounding, densest areas, would “throw away” out. This effect, added to the general expansion of the universe, would cause nearby galaxies to move away from us faster than normal. “This would give the appearance of a faster local expansion rate,” explains Indranil Banik, of the New Research. The Hubble tension problem would thus become a local phenomenon, without the need to revolutionize the entire cosmological model. The sound of the Big Bang as proof. What the new study of Banik and Kalaitzidis contributes is a much more fundamental test based on barionic acoustic oscillations. Although we call them “the sound of the Big Bang”, they are not sound waves that we can hear. They are the traces that left the pressure waves that spread through the superdense plasma of the primitive universe. These waves were “frozen” about 380,000 years after the Big Bang and created A characteristic pattern in the distribution of matter. This pattern works as a cosmic rule of about 500 million light years in length, which astronomers use to measure the expansion of the universe to different eras. The results. The team analyzed 20 years of measurements and compared them with two scenarios: on the one hand, the homogeneous standard model, without emptiness; and on the other, the model that includes the empty KBC. The results, presented at the National Astronomy Meeting 2025 of the Astronomical Society Royal, are blunt. According to the statistical analysis of the study, the model with a local vacuum conforms to the data in a spectacularly better way. While the standard model has a 3.3sigma voltage with observations, vacuum models reduce it to only 1.1sigma –1.4sigma. Calmly. The researchers consider “demonstrated” that A vacuum model is about 100 million times more likely than a model without emptiness. However, it is a preliminary study, which has not yet gone through the pairs review. Previous studies set very strict limits to the existence of such an influential vacuum, concluding that it is not enough to explain the entire Hubble tension. They also propose early dark energy as a solution. But Banik’s work offers one of the strongest evidence to date that the Earth could be in a very lonely region of the universe.

Iran has found the antidote to the Israeli iron dome. Is called Fattah and overcomes the speed of sound

by

Iran found A weakness In systems of Israeli defense. His offensive was focusing on the use of unconventional threats marked by Shahed drone swarms whose combat loss was very small compared to the missile cost to tear them down. Israel’s response was swift: fronts to unmanned devices He launched the Sarafcombat helicopters. Now the conflict has entered a new “hypersonic” phase. A hypersonic missile. On June 18, Iran marked a milestone in his confrontation with Israel to launch Your ballistic missile Hypersonic Fattahcapable of reaching at least match 5 speeds (and estimated, According to Iranbetween Mach 13 and Mach 15). This projectile, solid fuel, guided with precision and equipped with a mobile nozzle in its second stage, He managed to cross Israeli antimisile defense systems in what was defined by the body of the Islamic Revolutionary Guard (CGRI) as a “turning point” in the Operation “True Promise III”already in its eleventh phase. Not just that. Iran He presented the Fattah As a symbol of the end of Israeli aerial invulnerability, stressing that its deployment represents a direct blow to the dissuasive capacity of Tel Aviv. The initial reports indicated FIRE AND STRUCTURAL DAMAGES in areas of the center of Israel as a direct consequence of the impact. Characteristics and innovation. The Fattaah missile represents one of the most ambitious bets of the Iranian Aerospace Program. It was presented officially in 2023 as a national technological revolution. With a scope 1,400 kilometers And a maneuvering capacity both inside and outside the atmosphere, this missile was designed to effectively avoid conventional defensive systems. In that sense, its design is key, which incorporates A re -entry vehicle maneuverable (Marv), which allows you to change direction in the final phases of your trajectory to evade aerial defenses. Your solid fuel engine gives you an immediate response to the launch and your advanced guide system, as we said, next to an orientable thrust nozzle, allows you to execute unpredictable maneuvers that hinder your interception. Unlike traditional missiles, its trajectory can vary dynamically during the flight, which makes it a practically unattainable goal for air defenses that depend on predictable trajectories. A fattah missile National symbol. The missile is much more in National Key. In fact, he was baptized by the leader himself, Ayatolá Ali Jameneí, who also made him a propaganda symbol With the phrase “400 seconds to Tel Aviv” printed In Hebrew on a banner hanging in Tehran. During the Mass attack of October 1, 2024, several fattah-1 missiles already They had been thrown Against Jerusalem, but its recent use in the current context marks the first time that on the current conflict is incorporated tactically. The weapon also It is described by the body of the Islamic Revolutionary Guard (IRGC) as the “Israel’s beating.” The “hypersonic” club. The news has other readings. With the deployment of fattaah, Iran becomes In the fourth country in having and using hypersonic technology, adding to Russia, China and India. Each of these powers has developed Your own models with different characteristics in terms of launch platform, autonomy, type of propulsion and guidance mechanisms. The Iranian variant stands out for its Structural simplicity (solid propulsion in two stages) and its apparent tactical effectiveness. Plus: The ability to overcome multiple layers of Israeli defense during this phase of attacks positions Iran as an increasingly sophisticated actor in the field of ballistic deterrence. The Israeli answer. If the response to the Shahed were the Saraf, the Israeli reaction to the attack with hypersonic missiles has not been waiting. In the following hours, Tel Aviv launched a new OLADA DE BOMBARDEOS on military objectives in Iranian territory, intensifying a dynamic of cross retaliation that already adds seven consecutive days. Among the whites attacked They were included Five military helicopters at a base in Kermanshah, a land-land missile production installation, a war manufacturing center and a centrifuged plantwhich shows that Israel seeks to weaken both conventional capacity and Iranian nuclear infrastructure. The explosions felt even In the Iranian capitalevidencing that the Israeli campaign has expanded its spectrum of action and now points to nerve centers of Persian military power. Strategic implications. The last of the legs to analyze has to do with how the board changes in regional dynamics. The Fattah irruption In the battlefield it introduces a new destabilization factor in a complex conflict already. Beyond military symbolism, its effective use undermines confidence in Israeli defensive systemsconsidered among the most advanced in the world. This vulnerability could force Israel to reassess its air defense architecture and, at the regional level, it could alter the strategic calculations of other actors that until now considered unfeasible to directly challenge the aerial power of Tel Aviv. In addition, the fact that Iran can deploy missiles of this class from within its own territory gives it a significant operational advantage, reducing the need to depend on regional allies to execute long -range attacks. More technological and asymmetric. As In Ukrainethe crossing of attacks between Iran and Israel, more and more sophisticated, illustrates the evolution of modern conflicts towards scenarios where technological deterrence is A determining weight. While Israel maintains the Air Supreme Thanks to its fleet of F-35I and F-15 fightersas well as its operational experience, the appearance of weapons Like fattah Reduces its strategic advantage margin. Iran, limited in its conventional Air Force, has opted to compensate for its inferiority with the development of ballistic missiles and Advanced dronesin a wear war in which each new system can redefine the momentary balance. The Operation “True Promise III”therefore, it is not only a reprisal campaign, but an essay for a new Iranian doctrine based on speed, precision and unforeseen penetration.

The Spanish festivals are in crisis for Israel. Meanwhile, Spring Sound has included bombings in Gaza in its poster

by

We had not had such a moved season of festivals for years. With the vast majority of the great musical events of summer marked by controversy Related to the KKR Investment Fund, the Spring Soundwhich is celebrated this week in Barcelona, ​​has decided to position itself with an installation halfway between political exhibitionism and the commercial hook. That is pure spring Sound, too. The tunnel. Spring Sound has installed in the PARC of the Fòrum A 15 -meter tunnel that replicates the sounds of the bombings in Gaza. The name of the installation is ‘Unsilence Gaza’, it is the work of the Palestinian sound engineer Oussama Rima and has been done in collaboration with the NGOs Casa Nostra, Casa Vostra and Novact. These have stated that “in spring sounds the sound is emotion, connection, pleasure. But sound can also be the opposite: it can become a weapon.” To this have added a chilling fact: bombings can reach 170 decibels, “much more than the human body can bear.” But … how much of genuine commitment and how much for winking for the gallery in this installation? The problem with KKR. KKR is an American investment fund, one of the world’s largest private capital companies, and whose most criticized activities There are real estate investments in Palestinian territories occupied by Israel, such as Jerusalem Este, Gaza and the West Bank. In 2024, the Fund acquired Supersruct Entertainment, a company that organizes some eighty festivals worldwide and that in Spain is behind events such as Sónar, Arenal Sound, Viña Rock, FIB or Monegros. The reaction of the groups. The response was not long in coming from numerous groups, which They canceled their participation In many of the festivals, and in some cases they launched communications clarifying their exact relationship with KKR. Seventy bandsfor example, they demanded that Sónar a more compromised positioning. Voices have emerged that They ask for the boycott from the festivalsand some like Sónar himself have lost poster heads as ark. At the same time, others Artists like Kase.O either Angelus Apatrida They have decided to keep their commitments to the festivals, which has generated controversy and discomfort with some sectors of their fans. More than festivals. Spring Sound does not have those ties with the KKR, which allows him to adopt a more combative position with respect to Gaza. But he does it in the PS style: for a few years, the festival is giving up the Transformation of Spanish festivals into more than encounters to listen to music. In many of them, the poster becomes something completely secondarybelow socialization: it started years ago with the transformation of the Benicàssim festival at the unavoidable point of meeting of the indie girl Before British invasionand Spring Sound partly collects his witness. And with Noria. Perhaps the spring element that shows the most this option is the Noria that was installed in 2013. Since then they have worked in that direction by approaching the festival more to an leisure center than something else: Food Trucks and gastronomy positions, workshops and activities (many of them oriented to children), Conferencesmultidisciplinary exhibitions, handicraft, fashion and merchandising. An authentic brand and advertising exhibitor, which is the clear current orientation of spring, which in a sense questions its political meaning. It is not Kkr, but. Spring Sound has dodged the summer controversy that has affected practically all its competitors, but it cannot be said that she does not have her own economic commitments. In fact, after its financing There is the American Investment Fund The Yucaipa Companiesled by businessman Ronald Burkle. In that sense the spring Sound is matched with the rest of the festivals: It is a more turned event into a financial asset for foreign billionaires with the excuse of culture. And that it is a business they have never hidden it, as their progressive name changes demonstrate to Estrella Damm Spring Sound or San Miguel Primavera Sound as they were dancing their main sponsors. Ethics of income. Spring Sound financing has always generated innumerable ethical conflicts, as detailed This article by El Salto: Advertising of companies such as SEAT either Spotify while the claim of labor rights is raised; accusations of Purplewashing and Pinkwashing; Propaganda of brands of dubious ethics, for example linked to NFTS … and, in general, marketing of culture, which is always problematic. It spoke in depth by cross in A series of three controversial articles about the birth and evolution of the festival, and that made clear its abundant contradictions. It does not leave Barcelona. The reason that spring sounds so consciously the flag of Catalanity (and with it, of a certain political activism) is precisely that He has not managed to leave Catalonia. The international spring expansion Sound has been a failure: it closed All its Latin American editions In 2024 after the fiasco that supposed The 2024 edition in Madrid. Actually, the latter was the result of a tense Pulse with the Barcelona City Council where interests much more substantial than music were at stake. A series of sticks for the Financial of the Festival, which retains only the first of its first international expansions, Porto, Out of Barcelona. Intermediate point. Spring Sound is a first -order tourist attraction for Barcelona (left 272 million euros in the city in 2024according to a study by the MKTG Spain consultant). Thus, he plays (despite those nonsense with Madrid that They did not set For reasons that have nothing to do with their catalanity) not to lose their purely Catalan identity, with actions of the foundation linked to local training (many of their courses have joined the autonomy study programs). And within that identity is the claim in favor of Gaza, which maintain constant and explicit in aspects such as the programming of Radio Primavera Sound, where they do not have fear of positioning yourself. Business is Business. Spring Sound is a business, and that is why you have to take any type of positioning with tweezers: remember the … Read more

Its technology aims to reduce the scope of the enemy sound

by

In the underwater world, noise can be a sentence. The more silent a submersible, the lower the probability that it is detected by sounding. Although artificial intelligence begins to change the rules of the gameefforts to further reduce the acoustic firm do not cease. As SCMP points outthe last advance arrives from China, where a team of researchers has developed a technology that, in laboratory conditions, has managed to significantly cut the vibration that is transmitted from the engine to the helmet. The idea starts from replacing the traditional engine rigid supports with a hybrid structure of active-peasive insulation. The system was presented at A study reviewed by pairs published in Noise and vibration control By researchers from Jiao Tong University in Shanghai, in collaboration with China State Shipbuilding Corporation (CSSC). According to the authors themselves, a reduction of only 10 decibels at the noise level of a underwater vehicle could decrease its 32%detection range. A double control system. The system combines two elements. On the one hand, a steel-gum-steel ring that acts as a passive shock absorber. On the other, a series of 12 piezoelectric actuators that surround the engine and neutralize micromovimientos with the help of precision levers. These actuators are designed to adapt to reduced assembly space. The combination allows to reduce both structural vibrations and low frequency sounds, the most problematic for stealth. The system is governed by an FX-LMS algorithm, an adaptive method that coordinates the 12 actuators and avoids interference between them. Thanks to this intelligent management, the system can adjust your response in real time, which allows you to maintain control even in the face of unexpected variations in engine behavior. The method is based on rebuilding the interfering signal to feed the noise cancellation. Promising results, but in laboratory. The tests were performed with a 200 kg simulated engine mounted on a cylindrical metal housing. The system was designed to operate with a regime of 1,500 revolutions per minute (25 Hz). At 100 Hz, the passive system managed to reduce noise by 12 dB. With the complete system, the attenuation reached 24 dB. At 400 Hz, the reduction was 26 dB. The researchers explain that the chosen frequencies correspond to the most common spectral lines of the engine. A development still with questions. The study also indicates limitations. The rigidity of the rubber used in the passive system can be affected by temperature and pressure variations, and the durability of piezoelectric actuators has not yet been verified in real operating conditions. In addition, researchers do not specify what type of underwater would use this technology or the final impact that it would have on its global acoustic profile. In fact, the term “underwater vehicle” is used throughout the study. That is, they do not speak of diesel-electrical submarines or nuclear submarines. For now, it is an experimental development with promising results. The participation of CSSC suggests strategic interest, but there is no confirmation that this system has been integrated into any operational platform. What demonstrates is that China continues to bet on advanced technologies to reinforce its underwater stealth, an important factor in the modern naval war.

We have been knowing where a strange sound has been coming from. Now he has returned strongly to an island of Scotland

by

There are phenomena that challenge not only reason, but even perception same of reality. One of them is remembered in Scotland Since the end of the 90s, a low frequency buzz that is heard in different parts of the world and that, although for the majority it goes unnoticed, for those who perceive it is as real as it is unbearable. The buzz has been called The Humand on a Scottish island it seems that it has returned strongly. Breaking calm. In the apart Lewis Islandin the Scottish archipelago of the Hebrides, a persistent and strange low frequency hum has begun to disturb the life of its inhabitants, generating confusion, anxiety and health problems among those who claim to listen to it every night. It is a serious, pulsating and penetrating murmur, which prevents the sleep and causes vertigo, headaches and even alterations of concentration, according to testimonies collected by the British media. Despite its intensity for those affected, the phenomenon lacks a clear source and remains out of the reach of consensual explanations. The person responsible for documenting this disturbing anomaly is Lauren-Face Kirtley, founder of the support group “The Hebridean Hum”which has compiled dozens of complaints citizens and acoustic records in different areas of the island, in which a persistent signal of about 50 Hzvariable in intensity, but present in all cases. This data has allowed to rule out local sources such as port infrastructures, wind turbines or industrial facilities, and has redirected the search towards a possible origin … marine. Between the physical and the perceptual. Although some members of the group have considered physiological hypotheses such as otacoustic emissions (Sounds generated in the inner ear), the geographical disparity of the experience weakens this line of explanation. Pamela Weaver Larson, one of the group’s participants, said Do not listen to the buzz When he moves outside the island, which would indicate a Located environmental source more than a subjective phenomenon. This contradiction reveals the complexity of the case, which is registered in a much broader pattern: the call “Worldwide hum”an acoustic phenomenon documented for decades in various regions of the world, whose causes remain enigmatic and their simple existence remains questioned by scientific sectors. Glen Macpherson, founder of the World Hum Map and Database Projecthas compiled hundreds of testimonies that describe a buzz similar to the engine of a parked vehicle, more noticeable at night and in closed spaces, although generally described as omnipresent. The Hum, the beginning. As we said at the beginning, at the end of the 1990s Scotland began to perceive these hum. This was lived by Georgie Helop, a Scottish woman who after the death of her husband moved to the coastal town of Largswest of Glasgow, looking for peace of mind. What he found was the beginning of a sound nightmare: a constant buzzserious, similar to that of a truck in idle, which seemed to have no visible source and that was even more intense inside his own home. It wasn’t just an annoying noise. With the passage of time, the phenomenon began to cause physical ailments: headache, nasal hemorrhages, ear pain, chest oppression. As a desperate measure, Helop came to sleep in a tent in the garden, looking for peace that he did not find inside the house. Your case It was not isolated: Over time he discovered that not only in Largs, but in other parts of the United Kingdom, the United States and the world, many other people also reported to hear the same inexplicable buzz. Bewilderment. So and look back, Since 1973 similar cases have been documented in Very different towns: Taos In New MexicoHueytown in Alabama, Rome in the seventies, Bristol board In the United Kingdom. In many of these places, only a small fraction of the population, often middle -aged womendeclares to listen to the noise, which has led to multiple speculation about its origin. Some theories point to Physiological conditions as Tinnitusa sound perception without external stimulus. In the 1990s, hearing experts suggested that those who heard the buzz simply did not accept their clinical diagnosis. But over time, and thanks to the advancement of technology, some scientists have managed to detect real emissions, of such low frequencies Like those 50 or 60 hertziosand even others higher in the range of the Megahertzios, which has opened the door to explanations that go beyond the inner ear. Another explanation. Some hypotheses point to Combined frequencies which generate a kind of “milkshake” only perceptible to a minority with extreme acoustic sensitivity. Others suggest that the buzz originates in modern infrastructure (telecommunication towers, wind turbines, gas pipelines, military facilities), or even in electromagnetic or acoustic phenomena not yet understood. Project map started by Macpherson The map of an invisible sound. As we said, in 2012 a Canadian professor named Glen Macpherson began to listen to the buzz in his home in Sechelt, in the British Columbia. His personal experience led him to found the World Hum Map and Database Project, a collaborative platform where affected people can Register your location and share your experiences. Over the years they had already been reported More than 5,000 points of the planet where it was claimed to hear the buzz. The project has contributed to visible an experience that for decades was discredited or attributed to psychological causes. In the case of Helop, scientists who analyzed their home could Register anomal frequenciesconfirming at least partially that something physical happened in that environment. New explanations. Like those with the most recent cases, one of the explanations that has gained more strength associates the phenomenon with the geography of coastal areas. Largs, like many other points where the buzz is recorded, is located near the ocean. According to This theory exposed at the time In the Washington Poststorms in the sea generate waves whose impact is transmitted to the ocean bed, causing vibrations that extend through the earth’s crust. These oscillations could travel at great distances and be detected by those with … Read more
