Is it a good time to buy a Samsung Galaxy S26 or will the price drop soon?

by

According to the price at which the Samsung Galaxy S26 And taking into account our trend analysis and market history, this is how we see the purchase of Samsung mobile phones right now: 🟢 Buy with confidence Samsung galaxy 26 (base) Verdict “Launch” moment. It is on pre-launch sale and you will enjoy the novelty for a few months. official RRP €999 (Samsung store). Target price “on the street” Don’t pay more than €949 for the base model. Next release Samsung Galaxy Z Flip and Z Fold (expected in 2026), Samsung Galaxy S27 (expected in February 2027). Our recommendation Buy keeping two things in mind: 256 GB model: on Amazon it is on sale with a coupon for €949. 512 GB model: on Amazon it is on sale with a discount + coupon for €944. Our recommendation right now is to buy the 512 GB model taking advantage of the double direct and coupon discount. Regret cost Low. The mobile phone has just been launched and is on sale, so you can enjoy the novelty for a lower price. Why is the traffic light GREEN? Right now (March 2026) we are in its pre-launch period, so we have the news of a new mobile phone along with the offers that we usually have on most of the brand’s smartphones in this period. Thus, we find ourselves in this situation: Pre-release effect: The Galaxy S26 has not been launched yet, so we can enjoy a few months of the “newness” effect. Multiple offers: The launch has been accompanied by many offers, which may vary depending on the store we look at. Prices in their configurations: One of the most attractive offers lies in the “Double your storage”, a campaign that many stores have in which we have the 512 GB version at the same (or similar) price as the 256 GB version. This also affects higher internal storage configurations. Expert buyer advice: If you are going to buy a Samsung Galaxy S26 right now, go for the 512 GB or 1 TB configuration if you want to have a lot of storage, especially in its pre- and post-launch period, which is when it usually has the best offers in the first months of the cycle. Price history and change prediction The image above is a price chart of the previous generation, the Samsung Galaxy S25 (2024-2025), and we have superimposed it with the prices that we have seen so far on the Samsung Galaxy S26. This is what we see: What history tells us: During the first months of the cycle we only usually find post-launch offers, so it is not until after about three months that we can see better prices. Possible price drop in April: If we look at the price history of its previous generation, it was in April when we began to find more recurring offers, especially until the month of June. Keep an important fact in mind: Around October, we started seeing worse deals on the 128GB Galaxy S25. Because? Apple has a lot to do with it, since the iPhone 17 starts at 256 GB. To compete and sell, stores stopped launching offers on the 128 GB version, and began launching more on the 256 GB version. Hence, except in December, in November 2025 and in January and February 2026 we have seen crazy prices. So? If you see the price for 999 euros (RRP), you are losing money. The pre-launch “street price” right now is around 940 – 950 euros, don’t pay more than that, especially for the 256 GB base model. The best Samsung Galaxy S26 deals now: In the pre-launch period, both the official store and many suppliers have their own offers: Samsung has it for 749 euros paying with Bizum or Samsung Pay and with a direct discount. It allows you to have double the storage (512 GB) without paying more and you can save more money by handing over your old device. MediaMarkt has it for 899.10 euros if you pay through their app. amazon has it for 949 euros using the coupon and it saves you 100 euros if you are a student. The English Court has it for 999 eurosbut it offers a 5% discount when paying from the app, another 5% discount with the El Corte InglĂ©s card and another 10% when purchasing Samsung Galaxy Buds4 (the discount is on the headphones). fnac has it for 999 eurosbut it offers a 10% discount when purchasing Samsung Galaxy Buds4 (the discount is on the headphones). PcComponents has it for 999 eurosbut it offers training on artificial intelligence focused on Samsung Galaxy, allows you to have double the storage (512 GB) without paying more and allows you to finance the purchase at 0% for up to 36 months. Samsung Galaxy S26 (256GB) The price could vary. We earn commission from these links Is the Samsung Galaxy S26 for you now? To better understand whether or not you deserve to buy the mobile right now, these are the reflections I would make: âś… BUY IT TODAY IF: You need a cell phone because the one you have is broken or the battery no longer lasts you half a day. You want to enjoy the “new” effect on your mobile, also taking advantage of the fact that it is now on sale. You come from a very previous generation, from the Samsung Galaxy S23 back. â›” I DO NOT RECOMMEND IT IF: You have a recent mobile phone, a Samsung Galaxy S24 or Galaxy S25. The improvements, especially compared to the previous generation, are not great enough to justify the purchase at the time of its launch. You are going to pay the official price (999 euros). You can hold out for a few months, until at least April, which is when we start to see better offers. Good alternatives to the Samsung Galaxy S26 that I would buy If you still have doubts about whether or not to buy … Read more

an “invisible” galaxy made up almost 100% of dark matter

by

The Universe continues to be that great unknown. Not only because of its vast immensity, but because human research and subsequent theories that explain its functioning continue to require tweaks and reformulations. we have seen it when calculating the distances between planets of the Solar System, the size of Jupiter either what is the training mechanism of planetary systems. Now, a research team from the University of Toronto has discovered to the strongest candidate for a “dark galaxy”, something that until now was only considered a possibility. The candidate. The study presents the discovery of CDG-2, an acronym that literally means Candidate Dark Galaxy 2. It is an object 300 million light years away, in the Perseus cluster, with a peculiarity: it is almost completely dominated by dark matter, with a minimal number of stars. Thus, between 99.94% and 99.98% of its total mass would be dark matter and it only delivers a light of “only” six million suns compared to the brightness of tens of billions of the Milky Way. Context. Galaxies are something like the Lego pieces that make up the universe and they all contain dark matter. The dark matter It is something scientifically fascinating: it is invisible, it does not emit or reflect light, but its gravitational influence was the scaffolding on which galaxies were formed and is what holds them together today. In the Milky Way, estimates suggest that between 65 and 90% of the mass is dark matter, depending on the model, but astronomy has always wondered if there were even more extreme galaxies. The “dark galaxies” were until now just a theoretical prediction. Why is it important. To begin with, because it empirically confirms what the theoretical models contemplated, but it has more implications: It opens a new way to detect galaxies from statistically significant groupings of globular clusterswhich serve as a trace. As a case study: the most probable hypothesis is that neighboring galaxies ripped away the gas necessary for star formation, leaving only the skeleton. It makes us look at its “twin” CDG-1 with different eyes. Detected previously, it could be a case of an even more extreme dark galaxy, possibly a pure dark matter halo. How they discovered it. The research team came across this galaxy in a striking way: looking for its shadow, since it is practically undetectable. Their fingerprints were four globular clusters, small dense concentrations of stars around the Perseus cluster. After analyzing its disposition with statistics and ruling out that its grouping was a matter of chance, they pointed the three most powerful telescopes available, Hubble, Euclid and Subaru, towards that region and created the image that evidenced its existence. Is, in the words of the main researcher Dayi Li, “the first galaxy detected solely through its population of globular clusters.” Image: NASA, ESA, Dayi Li (UToronto); Image Processing: Joseph DePasquale (STScI) Pending subjects. However, CDG-2 is still a candidate and not a confirmation, which is why it keeps its name. To confirm with certainty the mass of dark matter it would be necessary to measure the velocities of its stars or clusters, something technically very difficult with current technology due to how little they shine. It will be necessary to wait for James Webb and new Euclid observations to improve the image of this object to better define it or continue finding more dark galaxies like it hidden in the universe. It would require measuring the velocities of its stars or globular clusters, something technically very difficult given their extreme tenuity. The next few years, with James Webb and new observations of Euclid, will be crucial to refine the portrait of this object and track whether there are more galaxies like it hidden in the large clusters of the universe.

The Samsung Galaxy S26 Ultra has shown us a wonderful future. One full of screens with privacy technology

by

Many revolutions come without us realizing it and by surprise. As if they were a supporting actor that no one seemed to pay attention to and turns out to be the real star of the movie: This is how the privacy screen arrived of the Samsung Galaxy S26 Ultra: an innovation that no one expected and that made the AI ​​or the cameras of that mobile barely matter. Because although all those things add up, they are an evolution that we were all waiting for. But the privacy screen thing is something else: it is an everyday revolution and so obvious that one can only think how it is possible that we are in 2026 and no one would have invented something like this before. Samsung, as our colleague Ana Boria rightly says – please, don’t miss the Short -, has suddenly destroyed the entire industry of tempered glass that protects privacy. For years we have seen how it was possible to add a “privacy protector” in the form of protective glass to our mobile phone or laptop. With it it was possible to prevent any curious/gossip from taking a look at our device over our shoulder, but Samsung has made these protectors no longer necessary, because it has shown us how this technology can be part of the device’s screen itself. The idea is not entirely new, of course. HP has already applied a similar idea in some of its laptops a whopping 10 years ago. He called it Sure View and developed it in collaboration with 3M. That technology effectively allowed the viewing angles of the EliteBook 1040 and 840 to be critically reduced, but the proposal did not seem to work. Image: Samsung. Samsung, however, has gone a step further because this privacy screen can not only be activated and deactivated whenever we want: it can even be activated or deactivated in a personalized way for each application: if you want the privacy screen mode to be activated every time you look at your bank application, you just have to select this option in the settings. The customization of this feature is also extraordinaryand Samsung allows you to adjust it so that it is activated automatically, for example, when we receive notifications, or that the screen also goes into “anti-gossip” mode just when we are entering a PIN for an application. With the function activated, the screen only looks good to those looking at it from the front. This is one of those ideas that show that not everything is invented in the world of technology and that a real practical and everyday improvement as “silly” as this can be much more important and impactful than some AI options that remain fireworks. In fact, here Samsung has surprised us with an innovation that should make apple blush: the Cupertino company does not stop boasting that They are the champions of privacyand although they have certainly traditionally stood out in this section, here Samsung has left them biting the dust. To them and to everyone. Privacy screens have already become one of the clear technological innovations of 2026. Now We just hope that all manufacturers follow the story and end up implementing similar systems on their mobile phones. That may take some time, of course, but today it seems inevitable to think that what Samsung has done is open the door to a wonderful future in which we will be much safer from gossip. Good for Samsung. In Xataka | Image | Xataka with Freepik

Samsung Galaxy S26 and S26+, features, price, technical sheet

by

As expected today, Samsung has revealed its flagships for 2026 through its Galaxy Unpacked. In it, in addition to the portentous Galaxy S26 Ultrawe have also learned all the information about the S26 and S26+, which are the terminals we will focus on in this article. Below these lines we tell you all the details. Samsung Galaxy S26 and S26+, technical sheet Galaxy S26 Galaxy S26+ SCREEN 6.3-inch 2X AMOLED panel FullHD+ resolution Refresh from 1 to 120 Hz 6.7-inch 2X AMOLED panel QHD+ resolution Refresh from 1 to 120 Hz DIMENSIONS AND WEIGHT 149.6 x 71.7 x 7.2mm 167 grams 158.4 x 75.8 x 7.3mm 190 grams PROCESSOR Exynos 2600 Exynos 2600 RAM 12GB 12GB STORAGE 256GB 512GB 256GB 512GB FRONT CAMERA 12 Mpx f/2.2 12 Mpx f/2.2 REAR CAMERAS Main 50 Mpx f/1.8, OIS 10 Mpx f/2.4 3x telephoto lens 12 Mpx f/2.2 wide angle Main 50 Mpx f/1.8, OIS 10 Mpx f/2.4 3x telephoto lens 12 Mpx f/2.2 wide angle BATTERY 4,300 mAh 25W charging Wireless charging Reverse wireless charging 4,900 mAh 45W charging Wireless charging Reverse wireless charging OPERATING SYSTEM Android 16 One UI 8.5 Android 16 One UI 8.5 CONNECTIVITY 5G Wi-Fi 7 Bluetooth 5.4 5G Wi-Fi 7 Bluetooth 6.0 OTHERS IP68 certification IP68 certification PRICE From 999 euros From 1,249 euros Conservative design As was the case in past generations, the two most affordable models in the family, the S26 and the S26+, share most of their specifications and are committed to a measured evolution in design to focus their efforts, above all, on performance and artificial intelligence. If you already knew the Galaxy S25the S26 will be visually very familiar. Perhaps the most obvious change in this sense is seen in the camera panel, which this time protrudes from the rear surface of the phone. However, in general terms, the device follows the same trend line that Samsung has applied to its devices in recent generations. As indicated in the technical sheet, the S26 maintains a compact body of 149.6 x 71.7 x 7.2 mm with a weight of 167 grams, while the S26+ grows to 158.4 x 75.8 x 7.3 mm and 190 grams. Both are built with Gorilla glass on both the front (Armor 2) as in the rear (Victory 2), and with certification IP68 which guarantees resistance to dust and water up to 1.5 meters deep for 30 minutes. Screen without surprises As for the screen, the S26 equips a panel LTPO AMOLED 6.3 inches with Full HD+ resolution and adaptive refresh rate of up to 120 Hz. That is, identical panel to the last generation. The S26+, for its part, has a 6.7-inch screen with QHD+ resolution and the same LTPO technology, also without surprises. Both panels reach a maximum brightness of 2,600 nits, and have HDR10+ compatibility. Samsung returns to the Exynos in Europe Here comes one of the most relevant points of this generation. Depending on the market, the Galaxy S26 and S26+ will have one or another processor under the hood, something they used to do until not long ago (the S24 already had this same two-chip strategy for different markets). In most international markets the Qualcomm Snapdragon 8 Elite Gen 5that is, Qualcomm’s top processor to date, while here in Europe (and it is known that also for India and the Middle East), Samsung will bet on its own chiphe Exynos 2600. We already know the Snapdragon 8 Elite Gen 5 from other phones, but this time it is optimized specifically for the Galaxy and integrates an eight-core CPU with two high-performance cores at 4.74 GHz and six efficiency cores at 3.62 GHz, accompanied by the Adreno 840 GPU. The Exynos 2600, for its part, uses a ten-core architecture with frequencies of up to 3.80 GHz and the Xclipse 960 GPU. We will have to wait to test it in depth in our analysis to draw conclusions. Both terminals arrive with 12 GB of RAM (the thing is not right now for more) and internal storage options of 256 GB or 512 GB. Cameras: unchanged hardware, but now with AI The rear camera system is identical on the S26 and S26+. Both have: A 50 MP main sensor (f/1.8, 24 mm equivalent focal length, 1/1.56″ sensor, dual-pixel PDAF and OIS). A 10 MP telephoto lens with 3x optical zoom (f/2.4, 67 mm, OIS). A 12 MP wide-angle camera with a 120-degree viewing angle (f/2.2, 13 mm, Super Steady video). Front camera with 12 MP sensor (f/2.2, 26 mm, dual pixel PDAF). In video, the terminals are capable of recording up to 8K at 24 or 30 frames per second, 4K at 30/60 fps and Full HD at up to 240 fps. All with support for 10-bit HDR and HDR10+. The great novelty in photography is not so much in the hardware, which remains practically the same as the previous generationbut in how artificial intelligence intervenes in the process. And Samsung’s new camera application will integrate conversational AI, so that the user will be able to ask the assistant to configure the framing, the shooting mode or even edit the photos using voice or text commands. Something similar to what Google introduced with the Pixel 10. In addition to this, there is the EdgeFusion function, which allows you to generate images with AI practically instantly and completely locally, without the need for an internet connection. AI takes over software even more As expected, the Galaxy S26 and S26+ arrive with Android 16 pre-installed and customization layer One UI 8.5. In addition to touches on visuals and usability, it is worth noting that Samsung has continued further expanding its focus on AImaking their devices the most complete in this area. In case you had forgotten, Bixby is still valid on these phones as a central assistant. Samsung promises deeper integration into native apps and greater understanding of natural language. The most striking novelty in this section is ‘Now Nudge’: the system detect the context of what … Read more

The Galaxy Ultra already had a scandalous screen. The Galaxy S26 Ultra directly changes the rules of the game

by

I don’t want to waste my time talking about seniority, but I’ve been dedicating myself to current technology and video games for more than a decade and I can say that, at this point, few things surprise me. There are evolutions and functions that are cool, but on very few occasions it is something groundbreaking. Then Samsung arrived with the screen of the Galaxy S26 Ultra and its privacy mode. And I tell you what it is one of those things that you have to see to believe. In the first impressions of all Samsung Galaxy S26 We have already told you the essentials. The South Korean company has put a lot of effort into providing its new models with artificial intelligence functions. According to their estimates, more than 80% of users see value in the features of AI and we have a call assistant to avoid the SPAM, agents who perform actions for usa photo editor to which we give commands with prompts and other functions that make more or less intense use of AI. However, what I have noticed the most is something done so that you do not ‘focus’ on the screen of the one next to you: the new privacy screen. It is a mix between software and software that is explained simply. Have you seen one of those tempered panels that are tinted so that they can only be seen from the front so that curious people can’t see anything? Well, that’s what the Galaxy S26 Ultra screen does. Yes with him S24 Ultra they introduced an anti-glare screen that worked very, very wellthey have now added another layer of technology and functionality. The operation is simple and has to do with the pixel matrix of the OLED panel. We have pixels that emit in a narrow spectrum and those that emit light in a wide spectrum. When privacy mode is not activated, the screen lights up all the pixels, allowing it to look great both from the front and at any angle. But, when we activate the new privacy mode, pixels that emit light in the wide spectrum are turned off. And that’s the trick. When that happens, as users, we notice that the brightness drops a little, but also that we can only see the screen if we are completely perpendicular. If we start to tilt the phone, we quickly lose the angle of vision to the point that at 30 degrees it is very difficult to see anything. In practice, whoever is next to you on the couch, on the train or on the bus, will not see anything at all on your screen. And this is great in terms of privacy, but also in terms of security. Because let’s see, you may be thinking that it is ideal so that no one sees your conversations. Telegram or a mischievous eye that tries to take a look at the gallery or the bank app. And yes, it’s useful for that, but also so that your PIN or important notifications don’t get caught. Because There are three ways to activate this mode: Activated at will in full screen. Activated when we run certain apps in full screen. Notifications only. For example, I don’t care if they see my Telegram, but I don’t care if they take a look at my photo gallery. So I can set it to turn on when I open the gallery and turn off when I exit. But, also, I can add another condition: When there is an app that asks for my PIN, it is automatically activated to hide the process. And the truth is that it works like a charm: it’s fast, transparent for the user once we configure it for the first time and… you don’t see anything, really. I know it sounds very “source: believe me”but in the photos and video above you can see it in operation. In addition, it is not tied to Samsung apps, but to anyone. And it also works with notifications, hiding only the notification bar at the top. Now, it has a catch. You may have noticed that I said “the screen of the Samsung Galaxy S26”, and there is a reason: It is a technology reserved for the most expensive model. We already saw this with the anti-reflective finish of the S24 Ultra and it is a decision that I understood. It is logical that manufacturers save exclusives for their most ambitious models. However, here we are no longer talking about a function to keep gossip away: we are talking about something focused on improving privacy and security. I think that little brothers should have it. What’s more, I think all brands should step up and copy this function. It’s going to make cell phones go up in price, yes, but the truth is that I prefer something like this to cell phones that are increasingly more and more powerful and with more and more –very expensive– RAM for AI functions. From now on, this Samsung ‘invention’ has become something to which I am going to pay close attention. And surely there is someone who doesn’t like anything: to manufacturers of tempered glass with privacy function. Because I have one from a very well-known brand and it works well, but it is a pain in many circumstances and, in addition, it interferes too much with the brightness sensor. That does not happen in this Samsung implementation. Samsung Galaxy S26 Ultra, 512GB, Smartphone with Galaxy AI, 200MP Camera, 12GB RAM, 5000mAh Battery, 3 Year Manufacturer’s Warranty + 1 Extra Year, Cobalt Violet Color (Spanish Version) The price could vary.

a “galaxy” that never lit up

by

If a galaxy is, above all, a collection of stars, what do we do when we find something that looks like a galaxy, but doesn’t have one? That’s the question it poses. Cloud-9an object detected in the nearby cosmic environment that defies common definitions. There are no explosions or flashes, just a silent cloud whose existence invites us to look at the first steps of galactic formation in a different way. What the researchers have identified is a type of object that had been in the realm of theory for years. Cloud-9 fits into the category of so-called RELHICa primitive cloud of neutral hydrogen associated with a halo of dark matter that never became a galaxy. According to NASAit would be a vestige of the first stages of galactic formation, preserved to this day in the local universe. Hubble as definitive proof. The key to the discovery was not to find something new, but to confirm an absence with an unprecedented level of precision. Where radio telescopes had detected hydrogen, Hubble found no trace of stars, not even the faintest ones. That combination of data ruled out the hypothesis of a dim dwarf galaxy and placed Cloud-9 in a different category. “Seeing that there are no stars is what shows that the theory is correct,” said Alejandro Benitez-Llambay, principal investigator of the program. “It tells us that we have found in the local universe a primordial block that never formed.” Cloud-9 is located about 14 million light years from Earth, in the vicinity of the spiral galaxy Messier 94, with which it appears to maintain a physical relationship. Its structure is compact and almost spherical, a rare feature among known hydrogen clouds in the nearby environment. The core is made up of neutral hydrogen and has a diameter of approximately 4,900 light years. Radio measurements indicate a mass of gas equivalent to around a million suns and, from that gas and assuming that the pressure of the material itself compensates for the gravity of the halo, the team estimates that the associated dark matter would be around 5 billion solar masses. When dark matter is not enough. Cloud-9 fits into a scenario long anticipated by theory, but difficult to verify: structures dominated by dark matter that manage to retain gas without transforming it into stars. For researchers, this type of object acts as a missing link between cosmological simulations and the observable universe. The cloud illustrates that not all dark matter halos evolve into luminous galaxies. Some are trapped in an intermediate state, offering a direct window into the processes that regulate when and how star formation is triggered. The object first appeared three years ago in a hydrogen gas survey by the Chinese FAST radio telescope, as a discrete signal on the fringes of Messier 94. Subsequent observations with the Green Bank Telescope and the Very Large Array reinforced the detection, but did not resolve its nature. Detecting these types of systems is especially complex because nearby, luminous objects tend to eclipse them, and because clouds can lose gas as they move through intergalactic space, further reducing their visibility. In addition, high-resolution radio data show slight distortions in the gas, compatible with some type of interaction with the nearby galaxy. Between being born or disappearing. The authors of the study suggest that the fate of Cloud-9 is not closed. A sufficient increase in mass would upset the current balance and push the gas toward star formation, something that has not happened so far. But there is also the possibility that the environment works against you. The proximity to Messier 94 could favor processes that remove part of the gas, further reducing its ability to evolve. In that case, Cloud-9 would end up dissipating without ever becoming a proper galaxy. The finding has also raised caution among researchers outside the study. Jacco van Loon, an astrophysicist at Keele University, has pointed out that other hydrogen clouds initially considered dark ended up showing unexpected stellar populations. In his opinion, proving that an object is really a relic of dark matter requires evidence that is difficult to obtain even with Hubble. This caution marks the next step of the work: expanding the search and using higher resolution observations to confirm whether Cloud-9 is an isolated case or part of a broader population.

Samsung Galaxy Z TriFold, first impressions. Samsung’s most ambitious leap in foldables has fine print

by

Imagine carrying a cell phone in your pocket that can transform into a 10-inch tablet when you fully deploy it. That is the promise of Samsung Galaxy Z TriFoldan idea that was already on the table and that really makes sense as soon as you have it in front of you. Closed, it behaves like a bar format phone with a 6.5-inch screen, something familiar and relatively comfortable, but just start opening it to understand that the South Korean company wanted to go one step further. I think it’s not just about gaining inches, but about materializing a complex idea. After the initial impact, my first reading of the Galaxy Z TriFold is that of a device that surprises with its degree of maturity within a still young category. It is noticeable that Samsung has focused on the solidity of the whole, on how the pieces are assembled and on conveying a certain confidence when handling it, something that, as my colleague Javier Lacort commented in 2024, has not always been evident. Before moving forward, it is worth remembering that we are dealing with first impressions, they are clear sensations, open questions, but without a thorough approval in search of definitive conclusions.

We are not looking at a conventional folding device, but rather a device with three panels and two folds that only supports two real ways of use: closed, like a phone, or completely open, “like a 10-inch tablet.” Unlike the approach we have seen in the Huawei Matewhere it is possible to use the device partially deployed with two active panels, there is no middle ground here. When you use it unfolded and the interior screen becomes the center of the experience, the TriFold begins to justify its approach. We are talking about a 10-inch Dynamic AMOLED 2X panel with 2160 x 1584 resolution, 120 Hz and a density of 269 ppi, figures that explain why it feels so visually solid indoors. My contact with the device has been in the Samsung offices, in the evening and with artificial light, and in that context the experience has been excellent, with vivid colors and constant fluidity. It is true that the maximum brightness of the interior panel is 1600 nits, compared to 2600 nits for the exterior screen, but I have not had the opportunity to test it outdoors. When you leave content consumption, the TriFold lets itself be loved in multitasking scenarios. The screen offers real margin to maintain multiple applications open at the same time without the experience feeling limited, something that marks a distance from smaller folding products. Everything is more comfortable and less compressed, and the whole thing conveys a sense of order that is appreciated. It also seems relevant to me that it allows executing Samsung DeX directly on the screen itself, without an external monitor, because it reinforces your productivity focus. Now, in the hand, the Galaxy Z TriFold makes it clear from the first moment that it is not a light or discreet device when closed. With its 309 grams and a thickness of 12.9 mm when folded, it feels powerful, even more than one would expect when reading the technical sheet. That said, it is also worth putting it in perspective, because in numbers it does not go to the most extreme part of what we have seen in first generation folding devices. Opened, the perception changes noticeably, the weight is better distributed and the whole is surprisingly manageable for a 10-inch screen. One of the elements that caught my attention during the test was the way in which the TriFold manages its own folding. It is not just a question of hinges, but of how the device conditions the user’s gesture to protect itself. The route is clearly defined and if you try to close it incorrectly, the phone responds with a vibration and a warning on the screen that tells you not to continue there, something that reinforces the feeling of being in front of a product designed to avoid errors. Although the interior screen is the TriFold’s great attraction, it is also its most delicate part. When unfolded, the two folds are there and are part of the experience, although not in an intrusive way. It is not something that is constantly obvious and, in many moments, you can forget about them, but when you change the angle or the light hits it in a certain way they appear. In my case, for years the folds have bothered me a lot in folding ones, but over time I have learned to … Read more

a supermassive black hole ejected from its galaxy at 3.4 million km/h

by

Until now, we thought about supermassive black holes like the immovable anchors of galaxies, being gravitational giants that keep everything in order from the center. But we were quite wrong, since the James Webb Space Telescope us has confirmed that, sometimes, these anchors break and are shot through intergalactic space as if they were real gun bullets. The study. A team led by astronomer Pieter van Dokkum of Yale University has presented the first observational confirmation of a wandering supermassive black hole. It is called RBH-1 and its existence is the result of one of the most violent events that physics allows: being “kicked” out of your home by gravitational waves. A scar. Detecting this is not easy, since black holes They cannot be seen with the naked eye, but the destruction they leave in their wake is analyzed. This is precisely what JWST saw when it detected a massive linear structure about 200,000 light years long (twice the diameter of the Milky Way), which connects a distant galaxy with a bright, fuzzy spot. After trying to analyze this destruction in more detail, the telescope itself has revealed that it is a discontinuity. In layman’s terms: there is something extremely massive moving at an absurd speed of 954 km/s, which is equivalent to 3.4 million kilometers per hour. A speed that would allow us to travel from the Earth to the Moon in less than seven minutes. How do we know? The question in this case seems obligatory: How do we know that it is a black hole and not a simple star formation? The answer lies in everything it leaves in its wake, since by moving at this type of high speed, the black hole It compresses the gas so violently that it generates a trail of hot plasma that can be measured, as well as the formation of new stars. And now science has been able to confirm that this gas is not heated by the light emitted by stars, but by the brutal collision of a target that has at least 10 million times the mass of the Sun. Why is he running away? The theory behind this phenomenon is not new, but has been predicted by general relativity for 50 years. But in order to understand what has happened here, we can see it in three different steps: The first thing that happened was the merger of two galaxies and their respective supermassive black holes that began to orbit each other. After this, a third galaxy arrives to join this party and its black hole interacts with the binary system formed before. Finally, a cosmic “kick” is given. In this case, the interaction of three bodies generates a great asymmetry in the gravitational waves that results in a black hole shooting out of the galaxy at a high speed. It’s not the first. We already knew about wandering “stellar mass” black holes (a few times the mass of the Sun) roaming our own Milky Way, detected by gravitational microlensing effects by Hubble or the Gaia mission. However, finding a supermassive, what is the type of object that usually lives in the heart of galaxies, is a milestone on a different scale. Why this matters. The confirmation of RBH-1 is not a simple curiosity for physicists, but validates models of galactic evolution that suggest that the universe is full of these ‘exiles’. And this shows that if supermassive black holes can be ejected so easily, it means that many galaxies could be “orphaned” of their central core, affecting how they grow and form stars.
