<ul class="summary-list"><li>A subatomic particle called the muon is wobbling far more than leading physics models can explain.</li><li>Its unusual behavior could be evidence of a fifth force of nature or a new dimension.</li></ul>Physicists at the Fermi National Accelerator Laboratory have found more evidence that a <a href="https://www.businessinsider.com/muon-experiment-physics-hidden-force-universe-2021-4">subatomic particle is behaving unexpectedly</a>. And the reason could be evidence of a new, fifth force of nature.Currently, there are four known forces of nature: gravitational, electromagnetic, and the strong and weak nuclear forces. These four forces help us describe how the universe works.But there are still cosmic wonders we don't understand — mysteries that the discovery of a <a href="https://www.businessinsider.com/fifth-force-of-nature-could-unlock-the-dark-universe-2016-8">fifth force of nature</a> may help solve.<h2>The magnificent muon and its unusual wobble</h2>In 2021, physicists using the Muon g-2 experiment at Fermilab noticed a certain type of subatomic particle, called a muon, was wobbling more than expected.Scientists at Brookhaven National Lab had <a href="https://science.nasa.gov/confirmed-muon-wobble-remains-unexplained#:~:text=How%20fast%20do%20elementary%20particles,widely%20in%20physics%2C%20is%20incomplete.">witnessed</a> a similar phenomenon 20 years earlier, in 2001, but this unusual behavior has remained unexplained, puzzling physicists for over two decades.Muons are similar to electrons — the tiny particles that zip around atomic nuclei — but are 200 times more massive; hence their nickname, "fat electrons."These fat electrons can penetrate objects like X-rays, Aylin Woodward reported for Insider, and have been used to help scientists <a href="https://www.businessinsider.com/hidden-corridor-great-pyramid-egypt-giza-cosmic-rays-scientists-2023-3">uncover a hidden chamber</a> in Egypt's Great Pyramid and <a href="https://www.businessinsider.com/muons-help-map-magma-inside-volcanoes-predict-eruptions-2021-11">peer inside the guts of volcanoes</a>.Now, they may help physicists unlock a new force of nature. <div type="image" title="Illustration of an atomic nucleus surrounded by electrons." height="776" width="1024" msid="102735864" hostid="261"></div>"Like electrons, muons have a tiny internal magnet that, in the presence of a magnetic field, precesses or wobbles like the axis of a spinning top," Fermilab said in a <a href="https://news.fnal.gov/2023/08/muon-g-2-doubles-down-with-latest-measurement/">statement</a> last week.To study these muons, physicists fired them into a superconducting magnetic ring and measured how they behaved as they raced around thousands of times at close to the speed of light. What physicists observed was that the muons were wobbling far more than could be predicted with the <a href="https://www.energy.gov/science/doe-explainsthe-standard-model-particle-physics" target="_blank" rel="noopener">Standard Model of Particle Physics</a> — a mathematical guide that physicists have used for the last 50 years to explain and understand the subatomic realm.<h2>A 5th force of nature</h2><div type="image" title="quantum fabric spacetime einstein rosen bridge wormhole worm hole space shutterstock_309841256" height="1600" width="2400" msid="102735865" hostid="261"></div>If the equations set down by the Standard Model can't explain the muon's unusual wobble, physicists will be forced to look for other explanations.One possible explanation is that the muons' behavior is dictated by a fifth force of nature. Others could be the presence of a new exotic particle, the existence of a new dimension, or another unknown space-time property, <a href="https://www.livescience.com/physics-mathematics/wobbling-muon-experiment-could-reveal-a-5th-force-of-nature-if-the-results-hold-up" target="_blank" rel="noopener">LiveScience</a> reported."We're really probing new territory," Brendan Casey, a senior physicist at Fermilab said in the lab's press release. "We're determining the muon magnetic moment at a better precision than it has ever been seen before."That said, there are two ways to use the Standard Model to describe the muon's wobble, and they offer conflicting results, per <a href="https://www.livescience.com/physics-mathematics/wobbling-muon-experiment-could-reveal-a-5th-force-of-nature-if-the-results-hold-up" target="_blank" rel="noopener">LiveScience</a>. One way scientists hope to resolve the discrepancy is with more precise measurements. That's why Fermilab physicists collected four times more data this time compared to 2021, enabling them to reduce experimental uncertainty by a factor of two, LiveScience reported."We expect another factor of two in precision when we finish" analyzing the final three years of data, said Graziano Venanzoni, the co-spokesperson of the Muon g-2 experiment at Fermilab.If the results reveal a fifth force of nature, it could help explain some of science's biggest questions, including: What is dark matter made of? What is dark energy? And why does the universe contain far more matter than antimatter?Scientists realize that they may have to move beyond the confines of the Standard Model in order to answer these questions. And mysteries like the muon's wobble are breadcrumbs leading the way to what could be the next revolution in physics.

A weirdly wobbly 'muon' particle might revolutionize physics by revealing a 5th force of nature or another dimension

Unbeknownst to you, several hundred strike your head every second. These subatomic particles — created when cosmic rays enter the Earth's atmosphere — are harmless and quickly decay into clusters of lighter particles.The particles penetrate objects like X-rays do, which make them useful to scientists, who used muons to uncover a hidden chamber in Egypt's Great Pyramid <a href="https://www.nature.com/articles/nature24647">four years ago</a>.Scientists also use ghostly muons to map the internal structure of volcanoes, which could one day help predict dangerous eruptions, according to <a href="https://royalsocietypublishing.org/doi/10.1098/rspa.2021.0320">an article</a> published last week in the Proceedings of the Royal Society.To create those maps, scientists measure how efficiently particles pass through magma flowing through caverns, chambers, and rocky passages in volcanoes, then use that information to create geological blueprints, according to Giovanni Leone, a geophysicist at the University of Atacama in Chile and lead author of the study.The technique, known as muography, may one day be the "ultimate detection system for magma," Leone <a href="https://www.nytimes.com/2021/11/10/science/volcanoes-muons-muography.html?smtyp=cur&amp;smid=tw-nytimesscience">told The New York Times</a>, adding that the technique makes it possible to track magma movements that may precede an eruption.<h2>X-raying the inside of a volcano </h2><div type="image" title="Sakurajima volcano" height="2592" width="3888" msid="87747047" hostid="261"></div>Muons are like fat, fast electrons: They have a negative charge, but are 207 times heavier than electrons, traveling at nearly the speed of light. That heaviness and speed allows particles to penetrate dense materials like volcanic rock. The denser the object, the more quickly muons lose speed and decay.Many muons can hit the side of a volcano and travel right through. But if the volcano is dense enough — say, because a passage is filled with magma — a muon won't make it out the volcano's other side. To spot which muons survived the journey, scientists set up muon detectors on the flanks of a volcano. Those detectors create an image of the volcano's guts by capturing the intrepid muons that didn't decay while passing through the volcano, and noting gaps where muons didn't survive intact. Some researchers do this mapping from the air by positioning muon detectors inside helicopters and flying near the volcano's flanks.Think of it like getting your leg X-rayed. During an X-ray, radiation passes through your leg and is captured on camera. If the radiation passes through unobstructed, the image appears black. But because your leg bones absorb some of the X-rays as they pass through, less radiation makes it to the camera, meaning your bones appear lighter in the image. In volcanic muography, scientists look for the same contrast: Muons that pass through completely cast dark shadows on the muon detector. But when muons hit dense parts of the volcano and decay more quickly, they leave lighter silhouettes. In short, the denser the object, the lighter the silhouette. <div type="image" title="cdms dark matter fermilab reidar hahn" height="0" width="0" msid="87747049" hostid="261"></div>The more muon detectors surrounding a volcano — some can be almost as large as a tennis court — the better the image.One detector yields a 2D image, according to David Mahon, a muography researcher at the University of Glasgow, who was not involved with the study."By using multiple detectors positioned around the object, it's possible to build up a crude 3D image," he told <a href="https://www.nytimes.com/2021/11/10/science/volcanoes-muons-muography.html?smtyp=cur&amp;smid=tw-nytimesscience">The New York Times</a>.<h2>Muons could help predict volcanic eruptions</h2><div type="image" title="mount unzen" height="2657" width="3985" msid="87747051" hostid="261"></div>Researchers have used muography to glimpse inside Japan's Sakurajima and Mount Asama volcanoes, as well as three volcanoes in Italy — <a href="https://www.sciencefocus.com/future-technology/how-scientists-are-using-cosmic-radiation-to-peek-inside-the-pyramids/">including Vesuvius</a> — and a Caribbean volcano in Guadeloupe.Beyond helping scientists map volcanic innards, the new article suggests muography could be used to spot magma reservoirs inside volcanoes that are primed to erupt and to track magma movement in real time. Eruptions are often preceded by magma rising toward the volcano's summit, and using muons to detect magma flow in that summit area may help scientists detect impending eruptions — allowing people to safely evacuate ahead of an eruption."Knowing these issues as early as possible buys critically important time for those responsible for the local alarm and evacuation protocols," the study authors wrote, adding, "forecasting violent volcanic eruptions is the Holy Grail for applied volcanology."

In fact, muons are deviating so much from what the laws of physics suggest that scientists are beginning to think their playbook is either incomplete, or there's some force in the universe we don't yet know about.Muons are like fat electrons: They have a negative charge but are 207 times heavier than electrons. Thanks to their charge and a property known as spin, they act like tiny magnets. So when muons are immersed in another magnetic field, they experience an infinitesimal wobble.But in a <a href="https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.126.141801">study released this week</a>, physicists at the <keyword id="1781100" type="COMPANY" weightage="60" keywordseo="fermilab">Fermilab</keyword> in Illinois reported a discrepancy between how much muons should be wobbling and how much they actually did wobble during a lab experiment.The difference is substantial enough that many scientists are convinced particles or forces we haven't yet discovered must be involved. The finding, in other words, offers new evidence that something mysterious has played a role in shaping our universe - something that's missing from the existing rules of physics."In this respect, the new measurement could indeed mark the start of a revolution of our understanding of nature," Thomas Teubner, a theoretical physicist from the University of Liverpool who was not involved in the research, told Insider. It's possible that this unknown phenomenon is also linked to dark matter, the shadowy cousin of matter that was created just after the Big Bang and makes up a quarter of the universe.<h2>Shooting muons in a circle at the speed of light</h2>When cosmic rays penetrate Earth's atmosphere, they create muons. Several hundred muons strike your head every second. They can penetrate objects like an X-ray does - a few years ago, scientists used muons to discover a hidden chamber in Egypt's Great Pyramid - but the particles only last for two-millionths of a second. After that, they decay into clusters of lighter particles.During its brief existence, each muon remains oriented around a single point, in the same way a compass always points north. But when it encounters a magnetic field, a muon's orientation shifts slightly away from that point. That crucial wobble, known as the g-factor, is what the Fermilab experiment is examining. <div type="image" title="brookhaven fermilab magnet" height="1118" width="1680" msid="81990684" hostid="261"></div>Fermilab is a US Department of Energy project with ties to the University of Chicago that's devoted to the study of particle physics.Scientists there can produce muons for study by running a beam of protons super quickly into metal using <a href="https://theconversation.com/how-a-muon-accelerator-could-unravel-some-of-the-universes-greatest-mysteries-131415">a particle accelerator</a>. So the researchers behind the new study took these muons and funneled them inside a circular electromagnet 50 feet in diameter. The muons then traveled at nearly the speed of light around the circle more than 1,000 times.When muons in the machine decay, ultra-sensitive detectors can measure which direction the resulting smaller particles are moving. Physicists can then use that information to calculate where each muon's fixed point is.<div type="image" title="fermilab" height="534" width="800" msid="81990686" hostid="261"></div>It should be possible to calculate the precise amount muons will wobble using the Standard Model of physics, which encompasses everything we know about particles' behavior. But the Fermilab team found that their muons' wobble did not match those expectations.Instead, it was off by one-third of one-millionth of a percent.That difference may seem mind-bogglingly small, but Teubner said it's actually "a milestone for particle physics." And it's unlikely to be the result of error: The team found that there's only a 1 in 40,000 chance the discrepancy in their measurement was due to random chance. "This is strong evidence that the muon is sensitive to something that is not in our best theory," Renee Fatemi, one of the Fermilab muon experiment managers, said in <a href="https://news.fnal.gov/2021/04/first-results-from-fermilabs-muon-g-2-experiment-strengthen-evidence-of-new-physics/">a press release</a>.<h2>A 20-year mystery</h2><div type="image" title="tess stars first science image" height="1019" width="987" msid="81990688" hostid="261"></div>This isn't the first time muons have not behaved in the way <keyword id="41551" type="ENTERTAINMENT" weightage="100" keywordseo="science">science</keyword>'s best theories would predict. In 2001, the Brookhaven National Laboratory in New York ran a similar experiment using the same giant electromagnet. Those results also showed that muons' wobble in the lab deviated from what it should have been. But those findings had a smaller statistical significance than Fermilab's: There was a 1 in 1,000 chance it could have been a fluke.Now, the Fermilab results confirm what Brookhaven physicists discovered 20 years ago - and that "has made the discrepancy which was already seen with the old result more intriguing," Teubner said.Fermilab is expected to release data from two more similar experiments within the next two years. A fourth experiment is also already underway, and fifth is in the works.<h2>Whatever is influencing muons could have a link to dark matter</h2><div type="image" title="cdms dark matter fermilab reidar hahn" height="450" width="600" msid="81990689" hostid="261"></div>According to Teubner, it's possible that some force that's not in the <a href="https://home.cern/science/physics/standard-model">Standard Model</a> of physics could explain the muons' whack-a-doo wobbles.That force, he said, may also explain the existence of dark matter, and possibly even <keyword id="1198268" type="PERSON" weightage="60" keywordseo="dark-energy">dark energy</keyword> - which plays a key role in accelerating the expansion of the universe. "Theorists would find it appealing to solve more than one problem at once," Teubner said.One hypothesis that could apply to both muons and dark matter, he added, is that muons and all other particles have almost identical partner particles that weakly interact with them. This concept is known as supersymmetry.But Fermilab's existing technologies aren't sensitive enough to test that idea. Plus, Teubner added, it's could be the case that the mysterious influence on muons isn't linked to dark matter at all - which would mean the rules of physics are inadequate in more ways than one.

A new experiment has broken the known rules of physics, hinting at a mysterious, unknown force that has shaped our universe

They’re smaller than an atom. And, the muon is one of them. It’s like an electron, but 200 times heavier. The particle is relatively unstable and only has a lifespan of 2.2 microseconds before it decays into an electron and two super-lightweight particles called neutrinos. <div type="image" title="17-0188-23_edited" msid="81968171" hostid="261" caption="&amp;lt;p&amp;gt;PhD student, Paolo Girotti, works on equipment for the Muon g-2 experiment&amp;lt;/p&amp;gt;"></div> The results of the experiment at <keyword id="1781100" type="COMPANY" weightage="20" keywordseo="fermilab">Fermilab</keyword>, dubbed Muon g-2, agree with what was found during similar experiments at the Brookhaven National Laboratory in 2001. This means the mystery of ‘what is making the muon particle wobble’ is at least two decades old. “Although these first results are telling us that there is an intriguing difference with the Standard Model, we will learn much more in the next couple of years,” said Fermilab scientist Chris Polly, who is a co-spokesperson of the Muon g-2 experiment and was the lead graduate student on the Brookhaven experiment. <cmsannotation type="cmsannotation" annotationid="How does the behaviour of muons go against the four fundamental forces of the universe?" comment="subhead" text="How does the behaviour of muons go against the four fundamental forces of the universe?">How does the behaviour of muons go against the four fundamental forces of the universe?</cmsannotation> As of now, there are four fundamental forces in the universe — gravity, electromagnetism, weak force and the strong force. These forces determine how all objects, big and small, interact with each other. Aside from gravity, three of these forces are explained within the Standard Model of Physics — the theory that classifies all known elementary particles to represent physicists’ best understanding of our universe at the smallest scales. So, when scientists sent muons around a 14-metre ring and then applied a magnetic field, the particles were supposed to vibrate at a very specific rate as dictated by the Standard Model of Physics. But that’s not what happened. Instead, muons were wobbling at a much faster rate that couldn’t be explained by what we know in physics so far. “This is strong evidence that the muon is sensitive to something that is not in our best theory,” said Renee Fatemi, the simulations manager for the Muon g-2 experiment. <div type="image" title="14-0180-28D_edited" msid="81968232" hostid="261" caption="&amp;lt;p&amp;gt; The core component of the Muon g-2 experiment is a 50-foot-wide superconducting electromagnet. When muons orbit around the storage ring at nearly the speed of light, they interact with the magnetic field and the quantum fields of the vacuum. &amp;lt;/p&amp;gt;"></div> “This quantity we measure reflects the interactions of the muon with everything else in the universe. But when the theorists calculate the same quantity, using all of the known forces and particles in the Standard Model, we don’t get the same answer,” she described. The most likely explanation is that there may be another force of nature at play but another hypothesis is that it could also be the work of another undiscovered subatomic particle like leptoquark or the Z-prime boson. Another hypothesised particle called ‘beauty quark’ was put forth by scientists at the Large Hadron Collider in Switzerland just last month. <cmsannotation type="cmsannotation" annotationid="What does this mean for physics as we know it?" comment="subhead" text="What does this mean for physics as we know it?">What does this mean for physics as we know it?</cmsannotation> The Standard Model of Physics is a barometer. Any evidence that the Standard is right, or wrong, can help physicists figure out if they’re on the right track. The Standard Model of Physics is also far from complete. In addition to the unknown force affecting muons, it can’t explain dark matter and dark energy, which we now know makes up most of our universe. The latest discovery has a one in 40,000 chance of being a fluke, which is far from the margin of error to proclaim an official discovery. The results presented on April 7 are only 6% of the total data that the muon experiment is expected to collect in the coming years. “Of course the possibility exists that it’s new physics.

<ul><li>The Earth may not have been born dry, but wet, with water reservoirs from the Big Bang stored within its foundational rocks. </li><li>A new study uses data from the <keyword id="59844" type="COMPANY" weightage="20" keywordseo="European-Space-Agency">European Space Agency</keyword>'s (ESA) Herschel telescope to explain how water was formed as ice on tiny dust particles wrapped inside cold tenuous interstellar clouds.</li><li>When the clouds burst to form a solar system, water saved itself by anchoring to pebble-sized dust particles.</li></ul>The prevailing theory on how the Earth got its water is that the planet was born dry and water was added later as asteroids rained down and delivered ice from the outer solar system. But that may not be the only explanation. <div type="image" title="bigbang" msid="81987394" hostid="261" caption="&amp;lt;p&amp;gt;Animation of the Big Bang&amp;lt;/p&amp;gt;"></div> It’s possible that Earth was actually born wet and water was a part of its very core since the Big Bang, according to a new study published in <a href="https://www.aanda.org/articles/aa/full_html/2021/04/aa39084-20/aa39084-20.html">Astronomy &amp; Astrophysics</a>. "It's fascinating to realise that when you drink a glass of water, most of those molecules were made more than 4.5 billion years ago in the cloud from which our sun and the planets formed," said Ewine van Dishoeck of Leiden University and lead author of the paper. According to him, this is the first study to dive into the journey of water throughout the entire star and planet formation process, including the steps in between. It combines past studies based on data by the European Space Agency’s (ESA) Herschel — a far-infrared space telescope to research the presence of water in space — while adding its own insights as well. <div type="image" title="W3_Herschel_large_edited" msid="81987306" hostid="261" caption="&amp;lt;p&amp;gt;This image by the Herschel telescope shows W3 , a molecular cloud located about 6,200 light-years away, where stars are forming in what is called a stellar nursery&amp;lt;/p&amp;gt;"></div> <cmsannotation type="cmsannotation" annotationid="Most solar systems are born with enough water to fill several thousand oceans" comment="subhead" text="Most solar systems are born with enough water to fill several thousand oceans">Most solar systems are born with enough water to fill several thousand oceans</cmsannotation> The Earth was born immediately after the Big Bang. At first, there were only interstellar clouds and clumps of rocks spinning around the Sun. The prevailing theory on how Earth got its water assumes that the Sun's heat was so strong that it boiled away any existing water in the area. It was only when asteroids came along and bashed into the planet that oceans formed. But, data from Herchel suggests that water may have been there all along, preserved within the foundational rocks of the Earth. In fact, solar systems across the universe may be born with enough water to fill several thousand oceans. <cmsannotation type="cmsannotation" annotationid="The Earth was born wet" comment="subhead" text="The Earth was born wet">The Earth was born wet</cmsannotation> The study proposes that most of the water was formed as ice on tiny dust particles wrapped inside cold tenuous interstellar clouds. The ice forms primarily formed in the pre-stellar stage, when temperatures were cooler and stars have not yet come into existence. It’s only when these clouds collapse that they form new stars and planets. The heat that is generated does boil away some of the water. But, most of the water is preserved in reservoirs within planet-forming disks — a spiral containing dust grains that eventually become bigger planets. <div type="image" title="AB-Aurigae_edited" msid="81987054" hostid="261" caption="&amp;lt;p&amp;gt;Actual image of a planet-forming disk around the star system AB Aurigae, 500 light-years away.&amp;lt;/p&amp;gt;"></div> Water saves itself by anchoring to pebble-sized dust particles in the disks around stars that have just been formed. And these pebbles serve as the building block for new planets — like Earth. “Water is transported from clouds to disks mostly as ice, with no evidence for strong accretion shocks,” says the study. The ice continues to grow on dust particles layer by layer. “Even at abundances that are somewhat lower than expected, many oceans of water are likely present in planet-forming regions,” it notes. <div type="image" title="p1535ay-crop" msid="81987206" hostid="261" caption="&amp;lt;p&amp;gt;An artist&amp;#39;s impression of innumerable Earth-like planets that have yet to be born over the next trillion years in the evolving universe&amp;lt;/p&amp;gt;"></div> Not only does this explain how water came to be on Earth, but it also proposes that new planetary systems are likely to be born with enough water to become habitable. Herschel data shows that water gas and ice are commonly associated with star-forming regions and that this conclusion is independent of the ‘environment’ or location of the Milky Way galaxy. A 2015 theoretical study based on data collected by the National Aeronautics and Space Administration's (NASA) Hubble Space Telescope believes that only 8% of the potentially habitable planets that will ever form in the universe existed at the time of the Big Bang, 4.6 billion years ago. Over the next 6 billion years, the other 92% will be born.

The cavernous space is roughly 100 feet long and sits almost directly above the Grand Gallery: a towering passage that leads to the tomb of Pharoah Khufu."This void was hidden in the construction of the pyramid. It is not accessible and we needed this new technique, at the right time, to identify it and to discover it," Mehdi Tayoubi, a co-founder of the HIP Institute and a leader of the research effort, called <a href="http://www.scanpyramids.org/" target="_blank" rel="noopener noreferrer">ScanPyramids</a>, told reporters during a Wednesday press briefing.The research group published its findings Thursday <a href="http://doi.org/10.1038/nature24647" target="_blank" rel="noopener noreferrer">in the journal Nature</a>."A lot of people tried to dig some tunnels looking for chambers," he added. "But as far as I know, no one has tried to dig something in this area. There was no theory expecting to find something as big as the Grand Gallery here."<div class="KonaFilter image-container display-table"><div><div class="image on-image"><a href="http://www.scanpyramids.org/">ScanPyramids/HIP Institute</a>An illustration showing where researchers used cosmic rays to locate a void in the Great Pyramid of Giza.</div></div></div>Tayoubi and his colleagues assert the "Big Void" is neither a data anomaly nor porous rock or loose rubble; in fact, the team is 99.9999% certain it exists, and a foremost expert on Egypt's pyramids agrees with that conclusion."I don't think this is bulls---," Mark Lehner, an archaeologist and Egyptologist at the <a href="http://www.aeraweb.org/" target="_blank" rel="noopener noreferrer">Ancient Egypt Research Association</a>, told Business Insider. "I put credence in the results, and I think they have indications of a large empty space."However, Lehner - who served on an Egypt-based advisory committee overseeing ScanPyramids' project, yet wasn't involved in the work - said the void is not likely packed full of undiscovered mummies, golden talismans, and other ancient artifacts.<h2>How to probe a pyramid with cosmic rays</h2><div class="KonaFilter image-container display-table"><div><div class="image on-image"><a href="http://www.scanpyramids.org/">ScanPyramids/HIP Institute</a>A view inside the Great Gallery of Khufu's pyramid in Giza.</div></div></div>Pyramids are confounding objects to study because they are so large; it's tough to see how they're constructed (and what they're hiding) without boring, digging, or blasting away their ancient and stony features."In the past it was easy. You have a scientist, and he says, 'I see a hidden door here,' and he can go and destroy this door and see what is behind it," Hany Helal, a pyramids expert at Cairo University and a ScanPyramids team member, told Business Insider during the press briefing. "Now, no one can allow for trial-and-error."Khufu's pyramid is a especially difficult case: It's not only the largest and most ancient Egyptian pyramid, making its hidden internal structure all the more labyrinthine, but also a prized national heirloom.Its construction of high and deeply embedded tunnels and chambers, like the Great Gallery, is also exceptional, Lehner said."In the popular imagination, it's the classic pyramid. But really it's the anomaly," Lehner added. "Nobody knew what Khufu did and no one did it afterward."<div class="KonaFilter image-container display-table float_right"><div><div class="image on-image">NASAAn illustration of cosmic rays generating muons and other high-energy particles in Earth's atmosphere .</div></div></div>However, the ScanPyramids team realized the same non-destructive technology used to peer inside volcanoes, called muography, might be used to probe structures like Khufu's pyramid.Muons are fast-moving, short-lived elementary particles that constantly shoot down from the sky. They're made when cosmic rays from supernovas, <a href="http://www.businessinsider.com/neutron-stars-crash-ligo-gravitational-waves-periodic-elements-2017-10">merging neutron stars</a>, black holes, and other high-energy objects reach Earth and pummel air molecules.This creates a shower of particles, including muons, of which thousands pass through our bodies every minute.Muons pass through air unhindered, and get weakly absorbed or deflected by rock. So, by setting out special muon-detecting film and devices inside a pyramid, any cavities will show up as bright spots (since fewer are being absorbed by rock and more are making it to a piece of film or a detector).<div class="KonaFilter image-container display-table"><div><div class="image on-image">ScanPyramids/HIP Institute; Business InsiderA plot of muon data showing the big void. This view is looking upward from the Queen's Chamber.</div></div></div>Inside the Great Pyramid, however, just 1% of muons reach inner chambers.This is why it took ScanPyramids two years to round up enough data: It takes months to expose a piece of film or run a detector, and the team used three different techniques to show beyond a doubt the void exists.<h2>Nothing to see here?</h2><div class="KonaFilter image-container display-table"><div><div class="image on-image"><a href="http://www.scanpyramids.org/">ScanPyramids/HIP Institute</a>Researchers explore the void they discovered in the Great Pyramid of Giza using augmented reality.</div></div></div>With the void discovered, but some details about it unknown, including its exact height and angle within the pyramid The group is also wary about labeling it a "room" or "chamber," since it's not certain that is the case."For the moment it seems very difficult to access this very big void," Tayoubi said, adding that more research will be needed to define its shape and extent without destroying and internal masonry.Helal and others would ultimately like to bore a small hole into slabs of rock to reach the void, pop in a tiny yet capable robot, and explore the space remotely.Lehner is not sure anything other than secrets about the structure of the pyramid will be found inside, though.As he explained to Business Insider, Khufu's father determined what pyramids should look like, but it was under Khufu's reign that their construction was pioneered - and experimented with."Nobody is assessing the reality of, the fabric of the pyramid itself," Lehner said. "This pyramid looks very regular from a distance, but it was made with a considerable slop factor."<div class="KonaFilter image-container display-table float_right"><div><div class="image on-image"><a href="http://www.scanpyramids.org/">ScanPyramids/HIP Institute</a>An aerial view of the pyramids of Giza in Egypt.</div></div></div>For example, he said, there are many "relieving structures," including extra ceilings and spaces stacked above the King's Chamber near the pyramid's center. Lehner said ancient Egyptians over-engineered these sections as insurance policies against structural collapse - a problem risked both by the crushing mass of the pyramid and shoddier construction of regions filled with rubble and sand.And that's where Lehner's self-described "shoot-from-the-hip" hypothesis about the void's purpose and role comes in."For all the world, I'll bet this is a relieving space for the Grand Gallery," he said, noting the feature exists right below the void. "They probably thought they needed some kind of relieving space to separate the slop factor from the fine masonry."Put another way: The big void may be nothing more than a stone-roof attic that protects a magnificent attraction several stories below it.ScanPyramids did not say how much its two-year effort cost in time for publication, but Lehner suspects it was expensive - and, despite commending the discovery, thinks such resources may be put to better use."Years ago I realized I had to turn my back to the pyramids to understand them," Lehner said. "To understand the pyramids, we need to understand how ancient Egypt worked - their economy, where they lived, what they ate, what drove them."Lehner, who runs a field school for young archaeologists interested in ancient Egypt, added that the void's discovery is not really a "wow moment." More shocking, he said, was when archaeologists found <a href="https://www.livescience.com/55439-ancient-logbook-on-great-pyramid-unveiled.html" target="_blank" rel="noopener noreferrer">a simple pyramid construction logbook</a>.Such documents reveal much, much more about the pyramids than the monuments themselves, he added, and they're found only through traditional and relatively inexpensive archaeological field work - not bespoke particle physics devices."Would the people of a 3,000-year-old civilization be better served by finding a hole?" he asked. "Or a year's worth of Business Insider?" <div class="margin-top"> <h3>NOW WATCH: <a href="http://www.businessinsider.com/nasa-pyramid-structure-ceres-saturn-moon-nasa-ahuna-mons-2016-9">This mysterious pyramid-shaped mountain in space is actually a gigantic ice volcano </a></h3> <div> </div> </div>

And, she did it with a borrowed boat. Kumanan told <a href="https://www.espn.in/olympics/story/_/id/31219458/with-borrowed-boat-wind-sails-nethra-kumanan-crafts-sailing-history-qualifying-tokyo-olympics">ESPN</a> that her boat had undergone serious damage during transit from Abu Dhabi’s port storage to Al Musannah Sports City in Oman as the Asian qualifiers were delayed due to the COVID-19 pandemic. Instead, she had to borrow a boat from her teammate, Ram Milan Yadav. "He [Yadav] was nice enough to understand that at the end of the day, it was about one of us winning an Olympic berth and helpfully gave me his boat," Kumanan told ESPN. "It was really a team effort." But, sailing had to beat out basketball, tennis cycling and the classic Indian dance form of Bharatnatyam for the girl from Chennai to be standing on the world stage. <cmsannotation type="cmsannotation" annotationid="The choice to sail beat out basketball, tennis, cycling — and Bharatnatyam" comment="subhead" text="The choice to sail beat out basketball, tennis, cycling — and Bharatnatyam">The choice to sail beat out basketball, tennis, cycling — and Bharatnatyam</cmsannotation> Kumanan will compete in this year’s <keyword id="395647" type="SPORT" weightage="20" keywordseo="Tokyo-Olympics">Tokyo Olympics</keyword>, which kicks off on July 23, in the laser radial class of sailing. The laser radial is a small boat, just big enough to carry one person, who has to navigate the boat. <div type="image" title="olympic channel 2_edited" msid="81984841" hostid="261" caption="&amp;lt;p&amp;gt;Laser radial boats competing in the Olympics&amp;lt;/p&amp;gt;"></div> And sailing is a love that Kumanan found early in life. Born in 1997, she was introduced to the sport during a summer camp organised by the Tamil Nadu Sailing Association at the age of 14. However, at the time, sailing was not her only interest. She was also into tennis, basketball and cycling. The one activity she loved, apart from sports, was Bharatanatyam. “Discipline, hard work and dedication are things I have learnt from the dance form and something that helps me even today,” Kumanan told the <a href="https://indianexpress.com/article/sports/sport-others/from-dancer-to-sailor-olympics-bound-nethra-kumanans-journey-7265160/">Indian Express</a>. But it was sailing that won out at the end of the day. Her first podium finish at an international event came in 2014 at the India International Regatta in Chennai. From there Kumanan went on to represent India at the 2014 and 2018 Asian Games. Last year, she first made history by becoming the first Indian to win a medal in sailing at the Hempel World Series in Miami, where she clinched a bronze. And since then Kumanan has had her eye on the ultimate prize — the Olympics. "I love it, it’s like no other sport, and I played everything as a kid,” Kumanan told the Olympic Channel. “Sailing has been different and more mental than any other sport that I’ve tried.” <div type="image" title="Olympic Channel_edited" msid="81984877" hostid="261" caption="&amp;lt;p&amp;gt;Nethra Kumanan tried other sports before deciding that sailing was where she wanted to excel&amp;lt;/p&amp;gt;"></div> <cmsannotation type="cmsannotation" annotationid="Still on the path to becoming an engineer" text="Still on the path to becoming an engineer">Still on the path to becoming an engineer</cmsannotation> Kumanan spends a lot of her time in Spain with Hungarian coach Tama Eszes, a two-time Olympian, to train. Back at home, however, she’s an engineering student at the SRM College in Chennai. Her dad, VC Kumanan, runs his own IT company. In fact, he uses his expertise by crunching data and providing analytical support, for his daughter, during training. According to Kumanan, being on the global stage representing India in sailing is another feeling altogether — especially when you come from a country where only a very few know that sailing is even an option as a career. <div type="image" title="nethra2_edited" msid="81984997" hostid="261" caption="&amp;lt;p&amp;gt;Nethra Kumanan with her parents and younger brother&amp;lt;/p&amp;gt;"></div> “If someone younger were to come up to me, I’d tell them that this sport takes a lot of time, a lot of hours in the water but it’s all worth it,” the 23-year old told the Olympic Channel. Whether she’s able to bring home a medal remains to be seen. But regardless of how she performs in Tokyo, qualifying itself has given her a place in the history books.

The Higgs boson is impossibly difficult to explain. But the fact of the matter is, if the Higgs boson did not exist, we would not be able to explain why fundamental particles, like electrons, have mass.
Without it, we could not exist. The universe could not exist.
Right now, we are all surrounded by something called the Higgs field. The Higgs field is always on. It is invisible to us, but within the field are little bosons that are popping up and vanishing all the time. Particles obtain their mass by plowing through the field.
"If the field wasn't around you, the electrons in your body would not have mass, and you would disintegrate," said Paul Padley, a physicist at Rice University who has been involved with experiments to discover the Higgs boson.
That's probably why the Higgs boson was nicknamed the "God particle," a term that the majority of physicists abhor, <a href="http://www.businessinsider.com/the-inventor-of-the-higgs-boson-hates-that-we-call-it-the-god-particle-2013-4" target="_blank">particularly Mr. Higgs</a> who is an atheist.
There have been lots of alternative explanations to the Higgs boson. Ideas have come and gone in the 50 years that it took to actually find the particle bearing the name of today's <keyword id="52659" type="ORGANIZATION" weightage="60" keywordseo="nobel-prize">Nobel Prize</keyword> winner.
On July 4, 2012, physicists announced that they had discovered a Higgs boson using the Large Hadron Collider at CERN. Padley is one of thousands of scientists who contributed to the discovery, but a limit of three people can win the Nobel prize, so it went to the first people to theorize the process of how particles obtain mass - finding the particle is proof that this process is real.
Below you can find a lightly edited transcript of our interview with Padley, who describes the science behind the elusive particle and the significance of its discovery.
Business Insider: Can we say for certain that scientists found a Higgs boson?
Paul Padley: Initially there was hesitation - we knew we had found something. But at this point CERN and the Nobel Prize committee have basically declared that this is a Higgs boson.
BI: You were involved in the discovery of the Higgs boson - as were thousands of other physicists on the experimental side. Do you believe it was fair to recognize just two recipients and why do you think this decision was made?
PP: They [Englert and Higgs] published the first papers on this Higgs mechanism. There are other people who contributed theoretically, but they were a bit later. The Nobel Prize committee is very strict that it just goes by order of publication. I don't know how they could ever award a Nobel Prize for the experimental work. The experiments are worthy of the Nobel Prize, but the current rules of the Nobel Prize committee are that they only give it to up to three individuals, and we're a lot more than three individuals.
BI: What is the biggest misconception about the Higgs particle?
PP: Everybody has trouble understanding exactly what it is. It's really hard to explain it because it's quite intricate mathematically. Fundamentally, <keyword id="55984" type="CITY" weightage="60" keywordseo="physics">physics</keyword> is a mathematical science. And when you try to explain it using English, or any language other than mathematics, you're going to come up short. In order to learn the mathematics behind the Higgs mechanism, you really have to go to graduate school in physics.
The underlying theoretical framework is something called relativistic quantum field theory. Take quantum mechanics, put special relativity on top of that, and then you have to apply that quantum mechanics and special relativity to the Higgs field. It's another level of abstraction mathematically from regular quantum mechanics. And that's actually the right framework to do things in.
BI: How did physicists know was properties they were looking for to confirm the existence of a Higgs particle?
PP: In the Large Hadron Collider, we take two protons and smash them together and scan through the debris looking to see what came flying out. When you create a Higgs particle, you don't measure it directly. It falls apart right away. We troll through the data looking for decay patterns that would correspond to something like a Higgs boson. For example, the theory predicts that the Higgs boson would decay to two photons some fraction of the time. So we look to see if we see these two photon decays, and we do see that.
BI: What role did you play in the discovery?
PP: I worked for a number of years on helping to construct and commission the CMS (Compact Muon Solenoid) experiment and participated in the analysis of the data. In particular, at Rice here we helped contribute some of the electronics that selects Muons - a type of fundamental particle that comes flying out of the detector. One of the ways in which the Higgs boson was discovered was by measuring it decay into two Z bosons. Those two Z bosons subsequently sometimes decay into muons. There was a large U.S. contribution - over a dozen universities and 100 people - that helped build the muon system.
BI: What's the practical benefit of this discovery?
PP: There's often a huge delay between when the theoretical idea is confirmed and when it turns into practical devices. We're at the forefront of knowledge. We're just trying to understand the basic laws of physics. Hopefully some day those will be put to good use. I think the immediate practical benefit is the technological advances that we have to make in order to do these experiments. These experiments are so technically challenging that sometimes we have to invent technology.

What Is A Higgs Boson? 

The elusive 'God particle' discovered by scientists in 2012 has always been hogging limelight for one reason or the other. Scientists at <keyword id="6624175" type="ORGANIZATION" weightage="100" keywordseo="Cern">CERN</keyword>, a European research organisation, found the Higgs Boson while conducting the Compact Muon Solenoid (<keyword id="15615" type="CITY" weightage="60" keywordseo="cms">CMS</keyword>) experiment, which is part of the Large Hadron Collider. CERN is expected to re-collect data around March 2015, and this time the team will onboard another member from India—IIT-Madras that is. 
 
CERN has collaborated with IIT-Madras to solve the mystery of the Gods particle, and the India’s premier education institute is aiming to make the best use of this wonderful opportunity. 
 
Experts believe that the latest move will help students to excel in the field of Physics. Numerous PhD students from the Physics department will get to work in the Large Hadron Collider (LHC), the world's largest and most powerful particle accelerator. 
 
On the other hand, members of various departments, which include physics, computer science and electrical engineering, at IIT-M can sharpen their skills by conducting experiments on data analysis, grid computing and high-end detector building. 
 
“Being connected to CERN can give many more students a taste of the power of fundamental research,” said Prafulla Kumar Behera of the physics department of IIT-Madras, pointing out that this is the first IIT and, in fact, the first institute from the southern States to have become a full member of the CMS. 
 It is important to note that Tata Institute of Fundamental Research, Mumbai, and <keyword id="71684" type="ORGANIZATION" weightage="60" keywordseo="Bhabha-Atomic-Research-Centre">Bhabha Atomic Research Centre</keyword>, Delhi and Panjab Universities have long been members of the CMS.

So, what is a neutrino?
Neutrinos are fundamental particles of matter that are created by a specific type of radioactive decay, called beta decay, and from nuclear reactions like the ones that take place in the sun and nuclear reactors. Neutrinos were also produced during the Big Bang.
Scientists know there are three different types of neutrinos - the different kinds exist because the particles spin in different patterns.
It seems like we know a lot about these particles, but really we don't, considering we're basically swimming in them.
"In seconds, trillions of these particles are streaming through your body," astronomer Ray Jayawardhana, author of "<a href="http://www.amazon.com/Neutrino-Hunters-Thrilling-Particle-Universe/dp/0374220638" target="_blank">Neutrino Hunters: The Thrilling Chase for a Ghostly Particle to Unlock the Secrets of the Universe</a>," said at a book signing on Dec. 10 hosted by the Secret Science Club.
Neutrinos are hard to pin down because they have almost no mass and interact weakly with other particles. It takes a giant chamber, like the one pictured above, full of extremely hot liquid hydrogen for scientists to be able to detect the presence of these particles.
The discovery of neutrinos. 
Though it has been theorized since 1930, we didn't discover the neutrino (in physical reality) until 1953. But its discovery was fundamentally important - it saved one of the most basic laws of science: The law of conservation of energy.
During beta decay, a neutron turns into a proton and spits out an electron. When scientists first measured what happens during beta decay they ran into a problem: The electrons were emitted with less energy than the reaction started with. It looked like energy was being lost somewhere in the beta decay process.
According to the law of conservation of energy, any reaction has to produce as much energy as it starts with. The scientists could not figure out an explanation for it, and some even considered giving up on the law.
But in 1930 the physicist Wolfgang Pauli came up solution, one that was considered insane for the time. He theorized that there must be another particle being emitted, it was just a particle that no one could see or detect.
According to Jayawardhana, Pauli had a great sense of humor about his crazy theory. He actually bet a case of champagne against himself and the ability of anyone to be able to detect the particle ever.
Finally, in the 1950s scientists confirmed that neutrinos exist.

Generally, neutrinos pass right through the ground. But a small fraction of neutrinos will actually hit something - sending out decay products that we can measure. There are several different types of neutrino detectors, but the basic idea is to catch a large number of neutrinos and hope that some of these will crash into atoms.
The image on the right shows the first recorded observation of a neutrino. The photograph was taken inside the chamber of a neutrino detector in the Argonne National Laboratory outside Chicago.
The spot where the invisible neutrino collides with a proton is circled in red.
Types of neutrinos.
Scientists know there at least three different kinds of neutrinos: electron, muon, and tau. The different types are referred to as "flavors" and they correspond with the way the particle is oscillating. Jayawardhana said the particles change flavors all the time.
"It's as if chocolate flavored ice cream changed to vanilla, then to strawberry, then back to chocolate - it really is that strange," Jayawardhana said.
The scientists detected the particle by mixing cadmium chloride in a tank of water. Cadmium absorbs neutrons really well. When the neutrinos collide with protons they produce neutrons and positrons. The positrons then collide with electrons and give off gamma rays.
Now that scientists have built more sophisticated neutrino detectors that can reliably detect all three flavors of these particles and study them, Jayawardhana says neutrinos have tons of potential.
