Radical New Theory Rewrites the Story of the Earliest Universe

Following the Big Bang, our universe expanded at an exponential rate. According to this theory, known as cosmic inflation, the explosive growth produced tiny quantum fluctuations that later evolved into galaxies. Cosmic inflation neatly explains how our universe got so large and mostly homogenous, and that’s why it’s remained a strong theory in cosmology for decades. But it’s far from perfect. Cosmic inflation depends on certain theoretical assumptions that can get rather arbitrary—not ideal fo

These Stylish Bluetooth Headphones With Unbelievable Battery Life Are Still a Steal After Prime Day

Discount available: Marshall's Major V headphones are worth it even at full price, but right now they're down to $111 -- or around 31% off -- on Amazon, which is still a great deal. I might not be a true battle-tested headphone expert like CNET's David Carnoy, but I still love headphones and I'm confident in what I like about them. My most recent pickup, the Marshall Major V on-ear Bluetooth headphones, quickly became a pair that I adore. What is Marshall? Marshall is a British audio hardware

5 Android phones you should buy instead of the Galaxy Z Fold 7

C. Scott Brown / Android Authority The Samsung Galaxy Z Fold 7 doesn’t officially hit store shelves until later this month, but it’s already established itself as one of the most exciting foldable releases of the year. With its impressively thin and light design, larger screens, and better cameras, the Z Fold 7 makes a strong argument for being the folding phone to buy in 2025. Although the US isn’t teeming with foldable handsets the way other markets are, there are still options to choose fro

iPhone 17 Air’s rumored accessory could be exactly what new model needs

iPhone 17 Air is a brand new model expected to debut this fall, with Apple prioritizing form over function. The ultra-thin, futuristic design will come with some compromises, but one rumored new accessory could solve my biggest concern: battery life. Apple planning special battery case for iPhone 17 Air, per report Numerous hands-on videos and photos have emerged in the last few months of iPhone 17 Air dummy models. And reactions seem extremely positive. For example, Unbox Therapy said, “That

The $2,000/week summer camps aiming to cure teens of phone addiction

With smartphone addiction a growing problem among US teens, one solution being tried is digital detox summer camps, where parents are charged around $2,000 a week to separate their kinds from their electronic devices. One kid sent to camp was so desperate to remain connected he brought three phones with him, handed over one, had another found in his bag, and was ratted out on the third by his room-mate … Smartphone addiction has been a problem for so long now that it was officially declared to

I tested Samsung's Galaxy Z Fold 7, and it became my new favorite foldable (despite the limitations)

Samsung Galaxy Z Fold 7 4.2 / 5 Very good pros and cons Pros Smallest crease on a book-style foldable Slim and light design Premium in-hand feel A more complete AI suite than its rivals Same main camera as Galaxy S25 Ultra Cons Costs $2,000 Sharp hinge corners Slow charging speed Weak 3x telephoto camera $2,000 at Samsung $2,000 at Amazon more buying choices The Galaxy Z Fold 7 is Samsung's biggest design overhaul since the Z Fold 2 in 2020, and it's back with a bang.

Phones with both a cooling fan and water resistance don’t exist, until now

OPPO TL;DR OPPO has announced the K13 Turbo and K13 Turbo Pro in China. These new phones have cooling fans and are water-resistant. The OPPO K13 Turbo series starts at ~$251 in China. We’ve seen a few gaming phones over the years with built-in cooling fans. Unfortunately, the need for a cooling fan vent means these phones aren’t water-resistant. Thankfully, OPPO’s latest phones buck this trend. OPPO announced the K13 Turbo and K13 Turbo Pro in China today, and both of these budget gaming ph

Report: iOS 27 to focus on new features for upcoming iPhone Fold

Act surprised: Apple is soon expected to formally kick off development of iOS 27. This year, Apple will have a big task: updating the iOS experience in preparation for its most radical new iPhone yet. Details are unclear, but iOS 27 will unsurprisingly focus heavily on optimizing software for Apple’s first foldable iPhone. This will include new features specifically for the iPhone Fold as well as ensuring that iOS as we know it today is optimized for the new form factor. In the latest edition

ChatGPT's GPT-5-reasoning-alpha model spotted ahead of launch

GPT-5 might be just a few days or weeks away, as we've spotted references to a new model called gpt-5-reasoning-alpha-2025-07-13. As spotted on X, OpenAI is testing a model called "gpt-5-reasoning-alpha-2025-07-13." This model was finalised on the 13th of July, and it appears to be the final round of testing.

Life Without Screens: This Camp Is a Teen’s Worst Nightmare

Summer. For teens not at work, it’s hot, it’s boring, and it’s an ideal time to close the door and spend about every waking moment watching, playing, texting, streaming—anything but talking—on the phone. With almost half of teenagers in the US saying they’re online almost constantly, the adults in their lives are growing more desperate to drag them off. Families are establishing screen-free zones in their homes, states are banning phones in schools, and a new kind of summer camp has emerged: dig

Foldable phones are thin and light in 2025, so why are these brands bending the truth?

Paul Jones / Android Authority TL;DR A Twitter user has shown that the Galaxy Z Fold 7 is thinner than the HONOR Magic V5. It turns out both HONOR and OPPO measure their foldables without the protective inner screen film. A closer look at product pages also reveals that some brands don’t include these layers when weighing their foldables. HONOR launched the Magic V5 in China earlier this month, and the company claimed that the white version was the world’s thinnest foldable phone at 8.8mm. H

The best Android phones for 2025

Read our full Google Pixel 9 Pro and Pixel 9 Pro XL review Processor: Google Tensor G4 | Display: 6.3-inch Super Actua, up to 120Hz | Cameras: Rear array (50MP wide, 48MP ultrawide with Macro Focus, 48MP 5x telephoto lens), 42MP dual PD selfie front camera with autofocus | Battery: 4,700mAh Finally, a smaller Pixel Pro. Google's Pixel series has long been one of the best Android phones around, with the Pro model being the superior version. But it was always a little too big and too cumbersome

I still prefer my Google Pixel 9 Pro over the expensive flagships - and it's not even close

Adam Breeden/ZDNET Last year, I was emphatic that my time with Pixel phones was over because Google had announced it was planning to inject even more AI "goodness" into Android. I saw that as an opportunity to jump ship. My goal was to buy the Nothing Phone 3. Then, as fate would have it, Nothing CEO Carl Pei announced that his company was going all-in on AI, and the next Nothing Phone would leverage the technology in ways no other device had. Foiled again. Also: This hidden Pixel camera set

iOS 26’s Photos app has a helpful new feature for events: Here’s how it works

At WWDC25, Apple introduced a few new capabilities to the Photos app for iOS 26. Most notably, it reintroduces a tab bar layout after last year’s controversial single-page redesign. It also allows you to create spatial scenes from existing photos. On top of those headlining features, there’s another underlying feature in the Photos app for iOS 26 that a lot of users might appreciate, and thats event details. Let’s explain. With iOS 26, if you’ve gone to a concert, sporting event, or some sort

5 underrated Android features I use all the time, and you should too

Andy Walker / Android Authority Features like split-screen mode, Quick Share, and various battery optimizations are more or less common knowledge amongst Android users. But Google’s OS has so many features, it’s easy for some to fly under the radar — especially since they can be buried deep within the settings. A lot of the features I use regularly aren’t talked about as much as they should be, partly due to the fact not everyone is aware that they even exist. I want to change that by sharing

Think smartphone cameras have peaked? Here’s what’s still to come

Robert Triggs / Android Authority I’ve seen some absolutely phenomenal camera phones cross my desk this year. The extravagant Xiaomi 15 Ultra and more mainstream OnePlus 13, in particular, have upped the ante on the iPhone, Galaxy, and Pixel triopoly, providing avid photographers more choice than ever before. While some of their best bits will inevitably trickle down to more affordable price points, thereby introducing more consumers to these superb capabilities, there’s also a sense that we m

The Hunt for a Fundamental Theory of Quantum Gravity

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally interwoven threads of space and time seem to stop short. These mysterious points are known as singularities. Singularities are predictions of Albert Einstein’s general theory of relativity. According to this theory, clumps of matter o

The Galaxy Z Fold 7 is my first foldable phone, and it totally caught me off guard

Adamya Sharma / Android Authority I’ve handled every foldable phone Samsung has ever launched. I have admired their engineering. I have watched with jealousy as people at airport lounges and hotel lobbies dramatically unfold their devices like they were unfolding a future I have purposely denied myself. But despite my curiosity and awe, I’ve stayed far, far away from foldables, especially book-style devices. Samsung’s flip phones still felt closer to home for someone like me who’s used only sla

Threat actors downgrade FIDO2 MFA auth in PoisonSeed phishing attack

A PoisonSeed phishing campaign is bypassing FIDO2 security key protections by abusing the cross-device sign-in feature in WebAuthn to trick users into approving login authentication requests from fake company portals. The PoisonSeed threat actors are known to employ large-volume phishing attacks for financial fraud. In the past, distributing emails containing crypto seed phrases used to drain cryptocurrency wallets. In the recent phishing attack observed by Expel, the PoisonSeed threat actors

Key takeaways: The rumored iPhone 17 Pro is expected to be released in early September. The Pro is rumored to be getting a scratch-resistant antireflective display. Colors could include black, silver, dark blue and orange. The new iPhone is likely just a couple of months away from release, and rumors about an iPhone 17 Pro have been ramping up.

Samsung Galaxy Z Fold 7 review: stunning, bendy, and spendy

is a reviewer with over a decade of experience writing about consumer tech. She has a special interest in mobile photography and telecom. Previously, she worked at DPReview. I’ve been using the Galaxy Z Fold 7 for a week, and I’ve run out of ways to say “It’s so nice.” It’s not essential, or life-changing; it’s nice. It’s an understatement, though. Samsung joins the likes of Honor and Oppo in making a folding phone that’s almost as thin as a regular phone, and it’s a trend with real benefits.

Nothing Phone 3 review: flagship-ish

Nothing says that the Phone 3 is its “first true flagship phone,” and it has put its money where its mouth is. The phone is getting a full US launch, and at $799, it costs exactly the same as a Pixel 9, Galaxy S25, or iPhone 16. That makes reviewing the Phone 3 refreshingly simple, because there are only two real questions that matter: is this as good as those three? And will it be as good as what we’re expecting from the new Pixel and iPhone models that are right around the corner? The answer

After six years, it’s finally time for me to switch back to a Pixel

C. Scott Brown / Android Authority In my five years working as an Android journalist, I’ve been known as the Samsung guy. That’s been an accurate description, but it may surprise you to learn that I used to be a Nexus/Pixel fanatic, using every Google flagship from the Nexus 6 to the Pixel 3XL. That changed toward the start of 2019, when I became tired of how unreliable Pixels were for me in a few areas and started to use Samsung phones exclusively. Recently, I got to spend a month with the Pi

Best iPhone in 2025: Here's Which Apple Phone You Should Buy

Phone makers promise varying lengths of long-term software and security support, ranging from just one year to as many as seven. These updates not only ensure you get many of the latest features, but also keep your phone secure. Phone cameras have gotten better over the past five years. But don’t be fooled by how many cameras a phone has. More is not necessarily better. Phones are big in general, with the smallest ones having a 6.1-inch screen and larger models topping out at 6.8 inches. That

HSBC note says Apple’s AI fumble may stretch iPhone upgrade cycle

In a new note to investors, HSBC says that the slow rollout of the AI features Apple introduced at WWDC 2024 has so far “failed to trigger significant improvement in user experience,” and that unless Apple gets back on track, users could end up pushing off their next iPhone upgrade. Here are the details. According to the note (via MacDailyNews), “the iPhone still represents about half of Apple’s sales,” but “initial hopes that AI would accelerate the renewal cycle have been short-lived,” as the

Best Back-to-School Tech Gear and Gadgets in 2025

Earfun has made some very solid budget earbuds, and now it's entered the full-size ANC headphone space with its new-for-2024 Wave Pro headphones. They list for $80, but they're down to $64 on Amazon right now if you apply the on-page coupon. While they may not sound as good as premium noise-canceling headphones from Bose or Sony, they're comfortable to wear, feature decent sound with punchy bass (they're a bit lacking in clarity and bass definition compared to more expensive models), and they of

Apple has three products launching this fall that we’ve waited a long time for

Apple has a big fall launch season up ahead, with 15+ new products coming. But per various reports and rumors, there are three particular products launching that we’ve been waiting a long time for. #1: AirTag 2 AirTag first arrived over four years ago, and it hasn’t had a single hardware revision since then. But rumors about an AirTag 2 have been circulating for a long while. Based on recent reporting, it sounds like we’ll finally get a new AirTag this fall. New features are expected to incl
