If you don’t have glasses for the solar eclipse, this homemade box made with cardboard and aluminum foil works just as well.

by

If you plan to see the solar eclipse on August 12, you will surely have already been researching methods to see it safely. To look directly at the Sun, x-rays, photographic negatives or any of the tricks that were recommended in the past are not useful. We can hurt our eyes a lot. Only approved glasses are valid. However, if you do not have or do not want to buy them, you can always resort to indirect methods, such as pinhole camera. It is an ideal method to use with children, since you can see the solar eclipse without risk And, what’s more, they have a good time making the box. Of course, it is a perfect plan to do as a family. We tell you everything you need to do it. Materials The materials to make the pinhole camera are very simple. First of all, you need a cardboard box. It may be worth an empty cereal container or shoe box. You also need a white piece of paper, a piece of aluminum foil, tape, a pencil, scissors and a thumbtack. How is the pinhole camera made? To make the pinhole camera, first we need to draw one of the shortest sides of the cardboard box on the sheet of paper. For example, the base of the cereal box. We place it on the sheet of paper, draw the outline and then cut it out. We must glue the resulting piece of paper inside, on the bottom of the box. Next, at the opposite end of the box, two square-shaped holes should be made. If we have a cereal box, which has that side open, we would have to glue a piece of cardboard in the middle, so that the two square openings on the sides can be seen. In this NASA publication there is a video that shows how it should look.. Then, cover one of the openings with aluminum foil secured with adhesive tape. Also, make a small hole in the center of the aluminum foil with a thumbtack. With this the pinhole camera would be ready. How to use it to view the solar eclipse? To use the pinhole camera we must position ourselves with our backs to the sun and look through the hole that doesn’t have aluminum foil. The sun’s rays enter through the small hole in the aluminum foil, which acts as if it were the lens of a camera, so that the image behind it is projected on the blank paper that we place at the bottom of the box. It should be noted that, logically, this device only works during partial solar eclipse. When totality is reached and the Moon completely covers the Sun, there is hardly any light that can enter through the hole, so there will be no projections to look at. The good thing is that, only during that totality, you can look at the sun directly, without glasses. Of course, you have to be very clear when the totality begins and when it ends, since with very little light we can damage our retinas. In short, this is a good way to indirectly see the partial solar eclipse without the need for approved glasses. If you are in one of the places within the band of totality, once it begins, you can look at the Sun directly, but be careful not to go too far. Unless you are in a town like Lerín, where The bells will ring to warn when totality begins and endsget away from the slightest ray that appears.

In 1778 Mozart attempted to teach composition to a French noblewoman. It didn’t go well at all, but thanks to her we now have unpublished works

by

Wolfgang A. Mozart died more than two centuries ago at the age of 35, but neither the time that has passed since his death nor his youth have prevented his talent from continuing to surprise us in 2026. Literally. Although few musicians have been as scrutinized as the Austrian genius, the Bibliothèque Nationale de France (BnF) just discovered an unpublished notebook from 1778 with scores from Mozart’s hand. The 44-page work contains seven pieces for flute and harp. Beyond the artistic value, the discovery sheds new clues about his life. The date: 02/02/2026. Sometimes chance is capricious. Coincidentally, that day, a week after the 270th anniversary of Mozart’s birth, one of the BnF conservators was rummaging through old manuscripts in the archive when he came across a piece that caught his attention. “I opened it and saw staves full of deletions, corrections and additions,” relates the BcN employee, François-Pierre Goy, responsible for the collections prior to 1800. “I recognized Mozart’s handwriting, his way of drawing the brackets, the rounded treble clefs leaning forward, the double final bars with fermatas above and below,” explained Goy to Le Monde. If it is not common to find an unpublished work by Mozart, that specific discovery was even more exceptional: the notebook dates from the end of the 18th century, but it is not signed and the BnF stored it among twenty manuscripts that were in the process of being recataloged. Following the trail. Goy had a hunch (one based on his extensive knowledge of the Austrian composer), but that is not enough to attribute an anonymous notebook to Mozart. To confirm his suspicions he went to Laurence Decoberthead of the Iconography and Documentation Service of the Department of Performing Arts of the BnF and a good connoisseur of the Austrian composer. In fact, he participated in the exhibition ‘Mozart, a French passion’, in 2017. Their analysis must also have pointed to Mozart’s authorship because Goy and his colleague decided to turn to a third specialist. Just a few months ago, in April, there was a knock on the door of Armin Brinzingthe director of the Mozart Library at the Mozarteum University of Salzburg. The expert did not have many doubts either: he confirmed the attribution and, above all, highlighted the historical importance of the work. “It is Mozart’s most important discovery in decades,” claims. What does the notebook contain? The document contains 44 handwritten folios with seven short works for flute and harp, as well as composition exercises, nothing strange if we take into account the context in which the experts place it: the BnF believes that it collects the composition lessons that Mozart gave to Marie-Louise-Philippine de Bonnières de Guînesan aristocrat three years younger than the Austrian and who is remembered above all for her skill as a harpist. “The use of French paper in the manuscript and its content (composition exercises and seven pieces for flute and harp) suggest that it bears witness to the lessons that Mozart gave directly from May to July 1778, during his last stay in Paris, to de Guînes,” explains the French organization. The young harpist, who was 19 years old at the time, was the eldest daughter of Adrien-Louis de Bonnières de SouastreDuke of Guînes and great lover of music. In fact, the duke himself was reputed to be a virtuoso flutist. By hiring Mozart as a composition teacher, he hoped that his daughter would create “great sonatas” for the instruments they both played: she the harp; he the flute. “I’ve tried everything”. The notebook located between the shelves of the BnF completes an episode in Mozart’s life that we already knew in part. Through a letter that Wolfgang wrote in May 1778 to his father, Leopold, who remained in Salzburg, we know, for example, that his young pupil may have been a skilled harpist, but she did not seem to have the makings of a composer. “She has no ideas, nothing comes of it. I’ve tried everything with her,” recognized Mozart frustrated. In general, his stay in Paris was not as profitable as he expected. He did not receive the recognition he desired and Goy explains that the duke never paid the Austrian for a flute, harp and orchestra concert that he commissioned. “We don’t even know if the Guînes family ever performed the pieces.” Why is it important? Locating a lost Mozart manuscript is always good news, even more so if (as in this case) it includes several unknown pieces. The notebook found by Goy, however, presents a series of peculiarities that make it even more interesting on a historical level. For example, the works are intended for a flute that the duke had bought in London, an instrument “rare, if not unique in Paris”, clarify from the BnF. Furthermore, Mozart did not devote the same attention to the flute or harp that he did to other instruments for which he created more repertoire, such as the clarinet. The new BnF work is also completed with annotations that seem 100% taken by the student and six blank final pages, without annotations. The big question. The manuscript is fascinating, but the truth is that experts seem to have few doubts about its origin. The BnF believes that it is one of the pieces “confiscated” in the mansion of the Duke of Guînes in mid-1794, during the Terror period of the French Revolution. Goy himself remembers that in the National Archives of France there is an inventory that cites “two bundles of sheet music” bound books taken from the aristocrat’s house in May 1794, after he sought refuge in England. The truth is that in recent years music lovers have enjoyed the discovery of various works unknown by Mozart, including pieces from his adolescence. “One of the most important”. Whoever wants to enjoy the short pieces for flute and harp that have just been resurfaced from the BnF archives can do so now in a performance made June 21 in the Ovale room of … Read more

His answer is called Zhuri and it already works

by

USA takes years working on methods to obtain solar energy directly from space. What is known as space solar energy is shown as an improvement on the conventional solar plants that we have here on Earth. The density of solar energy in orbit is six times greater than on Earth and the problem of weather interference is eliminated. However, it is true that there are quite a few technological obstacles that must be resolved. Although Europe, the United Kingdom and Japan have already made some proposals, the United States has a very prominent activity around the implementation of this type of projects. Therefore, it was to be expected that sooner or later China, the North American country’s eternal space rival, would join. After presenting several proposals project, Zhuri has finally been selected, with which Xidian University it has already started to work. From geostationary orbit to your electrical devices. The Zhuri mechanism, which means “chasing the Sun” in Chinese, consists of several steps. First, a 4.8-meter dome-shaped mirror suspended on a 75-meter tower is used, which is responsible for concentrating sunlight on a series of panels, similar to those used on Earth. This sunlight is used to obtain electricity, which cannot be transmitted directly in space, so it is then converted into microwaves, which can travel more efficiently. These then pass to a rectifying antenna, known as a rectenna, whose role is to transform these microwaves back into direct current electricity. That is the electricity that reaches the Earth. Other devices. In addition to the mirrors mentioned, Fresnel lenses of 2 to 7 meters wide have also been tested, as they are capable of focusing light even more efficiently, with less expenditure of materials. They even include cooling liquids that help manage solar heat, avoiding some of the inconveniences that it could cause. The first tests have been a success. In the first tests, scientists from Xidian University have obtained energy in the order of kilowatts, so for now the results are very positive. They are not alone. In the United States there are several projects aimed at obtaining solar energy directly from space. For example, Caltech has been researching in this area since 2013 and has already carried out some experiments in orbit in 2023. Also some private companies, as Goalplan to power their data centers with space solar energy by 2030. And, of course, the United States government could not be absent. The ARACHNE project, of the Air Force, is based precisely on this same goal. On the other hand, in Europe the ESA has the project Solaris and UK Space Solar. Both plan to start operating in 2030. And above all, Japan stands out, which has been researching in this area for decades and was one of the first countries to test wireless power transmission. Not to be confused with Reflect Orbital. The United States has other similar projects, as Reflect Orbitalbut they should not be confused, as they are much more controversial. With them, what reaches the Earth is not electrical energy, as with everything we have mentioned so far, but rather sunlight itself, which is “squeezed” even during the night. The objective of both types of projects is similar, but the means are very different. Beware of challenges. All countries that have tried to obtain space solar energy have encountered the same challenges. For example, they highlight problems in addressing the ease of deployment of folding or self-assembling structures, achieving precise microwave aiming, and ensuring the safety of the beams, both for the environment and for aircraft crossing the area where this electrical energy is being obtained. To address some of these handicaps, China uses modular units that fly in formation rather than a single massive structure, thereby improving endurance and making maintenance easier. Short term goals. Logically, the ultimate goal of this type of project is to bring solar energy to any part of the Earth. However, for now, we want to go step by step and achieve small preliminary challenges, such as wireless charging of satellites in orbit or the supply of lunar bases in orbit or on the lunar surface.

build submarines. The last one weighs five tons and works

by

Zhang Shengwu is 60 years old, he is a farmer and has not studied naval engineering, although throughout his long life he has had other jobs that can be assumed to be a handyman, such as a carpenter, welder or in the shipping industry. Back in 2014, Shengwu saw a person on TV building his own submarine and, just like you and I ventured to make a cod pil-pil after seeing Argiñano do it effortlessly (spoiler: it goes wrong), the farmer made the determination to build it for himself. As China Daily tellsnot even his family’s warnings about the risks or the cost stopped him. Just over a decade later, in early July 2025, Zhang Shengwu showed the world his creation with a successful test dive of his “Big Black Fish”, a homemade submarine weighing five tons capable of submerging eight meters, the latest of his creations. It is neither the first submarine he has made nor is it almost certainly the last. Some play petanque, I make submarines. The idea of ​​building a submarine from scratch caught his attention, so he invested 5,000 yuan (approximately 642 euros at the exchange rate) to buy sheet steel, a motor and a battery. In about six months he had built his first prototype, a submarine six meters long, 1.2 meters high, weighing two tons, how Sixth Tone collects. The bad news is that there was a leak. The good news is that the design of its prototype obtained a patent, a formal recognition by the Chinese state of the technical validity of the project. Obviously it didn’t stop there. He then built a surface ship that also got a patent. As Shengwu himself acknowledges, his head is never idle, so he already had the following project in mind: invested 40,000 yuan (just over 5,000 euros) to create the second generation of his submarine, which would later become the Big Black Fish. First submarine built by Zhang Shengwu. CCTV News His masterpiece: he Big Black Fish. He improved and lengthened the hull to seven meters and 1.8 meters high, so that its cabin now seats two people. For more stability, Zhang poured approximately two tons of concrete into the hull as a counterweight and mounted two ballast tanks at the bow and stern: “The tanks collect water to submerge and empty it to float,” explains for Sixth Tone. He didn’t want any more leaks like his previous project, so he welded every joint and installed circular hatches. This boat is capable of reaching speeds of up to four knots and Zhang is especially proud of its performance. So, details that “a small battery and a motor can propel this huge structure underwater. And it can submerge for half an hour without a single drop of water entering, it can even recoil.” Context. For someone to assemble something as complex and unintuitive as a submarine at home sounds exotic, but the reality is that in China it happens relatively often: in 2009 another inventor named Li Yuming Up to five homemade submarines were manufactured. In 2014 a former prison officer named Zhang Junlin He also developed a tourist submarine that he tested in the South China Sea. In 2015, a Shaanxi villager He borrowed 200,000 yuan to make a 9.2-meter one. Why is it important. It is no coincidence: the Chinese government has been betting on rural talent for years. Thus, in 2020 was fixed The goal is to have one million “innovation leaders” and 15 million entrepreneurs in rural areas by 2025. In fact, in Anhui, the province where Zhang Shengwu and the prison officer – inventor come from, these profiles can qualify for a one-time initial subsidy of 5,000 yuan if their activity remains stable for more than six months. Shengwu fits that profile: without a college degree but with a lot of time and persistence, he has successfully executed complex technology.

what it is, how it works and who can use Xiaomi’s AI agent platform

by

Let’s tell you What is Xiaomi MiMo Claw and how does it work?the artificial intelligence platform created by Xiaomi. This is a service that combines the manufacturer’s own artificial intelligence with the platform OpenClawthe popular AI agent. Xiaomi simplifies all of this to the maximum so that anyone can use it. So that you understand it well, we are going to start by explaining what exactly this tool is and how it works. Then, we will tell you who can use it. What is Xiaomi MiMo Claw MiMo Claw is a platform created by Xiaomi, built on OpenClawan open source AI agent framework. OpenClaw allows artificial intelligence to take control of your devices and do things for you on them, both to manage files and to do things on the network. About OpenClaw Xiaomi uses its most advanced artificial intelligence model, MiMo-V2.5-Pro. It is this version of MiMo that acts as an agent, being able to do the tasks you ask of it. Come on, it’s not limited to answering questions, it can also perform actions for you. Xiaomi has been testing this tool in beta for months, and on June 16, 2026, it confirmed the launch of its official version. Its great asset is yesu integration with Kingsoft Office (WPS Office), the office suite that is the Chinese alternative to Microsoft Office or Google Workspace. With this agreement, whoever uses its programs will have Xiaomi’s AI functions integrated. Xiaomi claims that in its internal tests at ClawEval, a testing ground that measures the performance of AI agents, its model had a task completion rate of 63.8%, with token consumption between 40% and 60% lower than that of similar products. Of course, remember that these are data that Xiaomi itself has given, it is necessary to treat the figures with caution. How MiMo Claw works MiMo Claw works as an AI agent, not a chatbot. This means that it is not limited to writing you answers for what you ask, it can take care of perform complex multi-step tasks without you having to guide them through each one of them. According to the data published by Xiaomi, the system can sustain more than a thousand consecutive calls to tools within the same session. This means that you do not lose track of what you are doing, and the logic is not interrupted in a long task. Come on, it’s harder to stay halfway without knowing what to do when the tasks are especially long. This is possible, among other things, because MiMo-V2.5-Pro ​​handles a context window of up to one million tokens. Tokens measure the amount of text and information that can be remembered and taken into account less work. The model natively supports the protocol MCP or Model Context Protocol. It is a standard that acts as a bridge between the AI ​​model and data sources that feed it to give it the information it needs to function. This means that it allows an AI to call external tools, being able to search the Internet, open files or execute code autonomously without the user having to do anything else. As we have told you, MiMo Claw is integrated into Kingsoft Office, so it focuses on the office field. MiMo Claw is compatible with more than 95% of common document formats, such as Word, Excel, PowerPoint or PDF among many others. This allows you to create complete cycles. For example, you can generate a document with AI, preview it and edit it in real time, all without leaving the Kingsoft Office ecosystem or resorting to other platforms. You can also create documents with a single click from templatesmanage files, and execute several tasks at the same time. This entire system is hosted in the cloud, so you don’t need to install anything nor use it on a powerful computer, although this also means that it does not have as much privacy as local alternatives. Of course, it is available 24 hours a day and can continue working or correcting errors while you sleep or do other things. Who can use MiMo Claw MiMo Claw can be used independently on the website of mimo.mi.comwhere in Use MiMo do you have a link for MiMo Claw. Of course, its deployment will be progressive outside of China. The service is in a phase where subscriptions and technical support for abroad are not yet enabled. Even so, when it arrives its free usage time will be 4 hours. MiMo Claw’s integration with Kingsoft Office is also designed for the Chinese domestic market. Therefore, if you use the version of WPS Office available in European app stores you will not find native integration with MiMo Clawit will only be in the Chinese versions. Therefore, at the moment MiMo Claw can only be used in China, and we will have to wait to see if it ends up reaching Europe. European data protection regulations are strict, so it may take a while to arrive.

What is Gemini Spark, what you can do with it, how it works and who can use it

by

Let’s explain to you What is Gemini Spark and how does it work?the new function of artificial intelligence integrated within the application Gemini. This is a response by the company to OpenClaw and others AI agentsbut aimed at helping us manage our digital life. The idea is not so much to do things for us on the computer as to be able to carry out online tasks autonomously, and even when our mobile phone or computer is turned off. We are going to explain this concept to you so that you understand it well, and then we will tell you how it works. What is Gemini Spark Gemini Spark is an artificial intelligence agent created by Google, and integrated into the Gemini application. AI agents are artificial intelligence systems capable of carry out actions autonomously. You ask them to do a task, and they carry out all the steps interacting with third-party services without the need for your supervision. Come on, it’s like a secretary who does tasks for you. In the case of Spark, it will be able to reason based on what you ask of it and the information it obtains from your connected applications. With this, then will take actions on your behalf interacting with these services. With Gemini Spark you can assign it a task and it will start working on it autonomously, even with your phone and computer turned off. And as one of the aspects that always worries security agents, Google assures that Spark is designed to consult you before taking important actions. Come on, you will have the final decision in these things. Spark can be working in the background 24 hours a day, seven days a week when you ask it to do something. It runs on the Gemini 3.5 model, uses the Antigravity harness, and integrates with Google Workspace tools such as Gmail, Slides, Docs, and all the tools in the company’s office suite. The difference with the normal Gemini is the following. AI chatbots require you to have it open for it to do things. Then, you ask them to do something, they respond and do it, and that’s it. The session ends there. Spark for his part maintain a persistent presence in your apps and digital environment, when you give it the order it can work in several steps and continue doing it in the background while you do other things, or while you sleep. How it works and what you can do with Gemini Spark Gemini Spark doesn’t live inside your device, but on dedicated Google virtual machines. This is what makes keep running in the background even if you close your laptop or lock your mobile. It connects to Gmail, Docs, Slides, and other Workspace tools with structured API integrations, making it more predictable than agents navigating the desktop pixel by pixel. This agent can connect natively with Gmail, Calendar, Drive, Docs, Sheets, Slides, YouTube and Google Maps. It is important that you know that these connections are disabled by defaultand you will be the one who decides which of them you want to activate to work with Spark. Spark can use a remote browser to leave the Google ecosystem. This way, they can enter a website and interact with it to perform tasks such as adding products to a shopping cart on your behalf. This tool will be able to do complex jobs for you. You can set recurring tasks to be done as often as you decide, teach it new skills, and let it execute multi-step jobs on your behalf. You can also organize your Google Drive files, even adding them to a spreadsheet by adding tags and notes. It can also automatically extract data from emails, create folders in your Drive cloud, etc. You can also teach it personalized behaviors or “Skills” to repeat, such as reading your last 50 emails sent, generating a style guide with your writing style and applying it when you ask it to write an email, and more. Another thing you can do is configure schedules to organize tasks with schedules or when conditions are met. For example, you can ask that every Monday at nine in the morning scan your inbox and summarize your emails, propose a list of priority tasks, or block gaps in your work calendar. You will also be able to create written documents or presentations from a prompt in tools such as Docs or Slides. It can review events, respond to invitations or schedule calendar meetings, convert email chains into a travel plan, record expenses in a spreadsheet, analyze past bills to anticipate future household payments, add recurring reminders, browse websites and compare options, help you complete reservations, and much more. The most important thing is that all this is going to do under your supervision. It’s as if Spark were an employee, who will send you updates on steps it deems critical, and will require your explicit approval to perform high-risk actions, such as sending emails. Who can use Gemini Spark Gemini Spark is part of the Google AI Ultra subscription. This means that if you want to use it you will have to go for the most expensive subscriptionwhich in Spain means paying a minimum of 100 euros per month.

They have asked 1,600 experts how the Universe works. They don’t agree on almost anything

by

We continually read news about new findings that they defy the known physics of the Universe. This may lead us to ask ourselves something: do we know so little about the Universe that absolutely everything challenges it? To answer this question it is important to give a little context. Yes, a lot is known about astrophysics, but when we talk about something as immense as the Universe, even that “a lot” can fall short. Furthermore, much of this information is based on hypotheses that have been accepted as consensus, but not on absolute truths. Therefore, it is not strange that in the largest survey ever conducted It has been proven to astrophysicists and astrophysics fans that there is a lot of disagreement on almost everything related to the cosmos. The largest survey. In 2024, during an astrophysics conference in Copenhagen, a survey was carried out in which 85 experts participated. All of them had to answer a series of questions about some of the best-known theories in astrophysics. With this survey it was seen that there is a lot of disagreement, even in those theories in which there is supposed to be a great consensus. In order to check whether these disagreements were a result of the sample size, a new survey was carried out in 2025, this time with 1,600 people who had to answer 11 questions. Some participants were experts from the American Astrophysical Society. Others were amateur readers of Physics Magazine. With a larger sample, the results were very similar. There is very little consensus. From hypotheses to certainties. Science in general, and astrophysics in particular, is built on hypotheses that evolve as scientific advances are made. For this reason, it is often more full of probabilities than certainties. It is important to differentiate different branches of science. In health sciences, there are certainties. For example, we know that antibiotics attack bacteria and are not useful against viruses, no matter how many people insist on taking them for the flu. We also know that their abuse can be very harmful, since it contributes to the development of resistance in bacteria. Those are certainties, although logically there is also information that evolves over time. In astrophysics, hypotheses accepted by consensus often outnumber certainties. There are very clear certainties, such as that the Earth is not flat or that it revolves around the Sun. But also some hypotheses with which not even experts agree. Cosmic inflation wins. The issue on which there was the greatest consensus in the 2025 survey, the results of which were recently published, was cosmic inflation. That is, the hypothesis that points to an exponential expansion of the Universe which began in its first moments, after the Big Bang. 51% of respondents agreed that this theory explains many problems in cosmology at once and therefore has a high probability of being true. Talking about the Big Bang. The existence of the Big Bang was another of the theories with the greatest consensus in the survey, although the truth is that the figure is nothing to write home about either. 25% of the participants agreed that this event gave rise to the Universe 13.8 billion years ago. On the other hand, there were 68% of people who indicated that the Universe was born at a time when there was a large increase in temperature and density, but they did not indicate when that occurred. Disagreements with dark matter. Gravitational behaviors that do not respond to the observed mass have been observed in the Universe. That is, it seems as if there are massive objects exerting a gravitational attraction on others, but these objects are not detected, not even large accumulations of atoms. There is nothing. 27% of those surveyed consider that this can be explained by the existence of dark matter. However, there are 12% who believe that all this may be due to changes in the behavior of gravity on cosmic scales. That is to say, when we talk about the immensity of the Universe, the gravity exerted by objects is not the same. On the other hand, there are 5% of people who consider that the key is in primordial black holes. Although here we must emphasize that one of the hypotheses about the origin of dark matter is that it is formed in part by primordial black holes, so they would not be denying its existence. String theory to solve incompatibilities. The theory of general relativity was proposed on large, cosmic scales. On the other hand, quantum mechanics talks about the behavior of matter on a subatomic scale. Both questions seem incompatible, but to understand the Universe we need to work at both scales. Therefore, for a long time there has been thought about a theory that helps unify both issues. This, for 19% of those surveyed, is string theory. In it, subatomic particles, instead of being treated as points, are considered vibrational states of a more basic extended object, called a string. Normally, when we try to calculate the energy of a particle by considering it a mathematical point, without extension, we get closer to it eternally. We can do a kind of infinite zoom. On the other hand, when the points are replaced by strings with a minimum length, a result must necessarily be obtained. It does not tend to infinity. On the other hand, in string theory gravity, which not normally considered on a quantum scalearises naturally. Another hypothesis. The point is that, in the survey we are talking about, there are 12% of people who consider that string theory does not solve the problem, but that another theory does: that of loop quantum gravity. This, basically, acts in a completely opposite way. String theory emerges with quantum mechanics as a starting point and tries to find ways to make gravity make sense. On the other hand, the theory of loop quantum gravity starts from the General Theory of Relativity and attempts to quantize it in a way that … Read more
