LIGO Detects Most Massive Black Hole Merger to Date

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories.

The signal, designated GW231123, was detected during the fourth observing run of the LVK network on November 23, 2023. LIGO, the Laser Interferometer Gravitational-wave Observatory, made history i

Merger of two massive black holes is one for the record books

The results were presented at the Edoardo Amaldi Conference on Gravitational Waves in Glasgow, Scotland. The LIGO/Virgo/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. LI

Dozens of ‘Ghost Galaxies’ Are Orbiting the Milky Way, Astronomers Suspect

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best understanding of how the universe works. But there’s a problem. According to the theory, the Milky Way should have significantly more satellite galaxies than scientists have observed with telescopes and predicted with computer simulations. By combining the highest-resolution supercomputer simulations

Xbox Ally Gaming Handheld Price Could Be Higher Than Expected, Leak Suggests

The ROG Xbox Ally handheld gaming device from Asus and Microsoft debuted last month, and there were a lot of questions about the new portable. The big question about price might have been answered by a leak, and it looks like this handheld won't be cheap. A Google search screenshot showed a listing for the Xbox Ally and upgraded Ally X at 599 and 899 euros, as first spotted by Spanish gaming site 3DJuegos on Sunday and reported by Insider Gaming. This would put the Xbox Ally at approximately $7

US government is giving leading AI companies a bunch of cash for military applications

The US Chief Digital and Artificial Intelligence Office (CDAO) is handing out millions of dollars to the leading AI companies to develop military applications. Each of these "awards" are worth up to $200 million, with Anthropic, Google, OpenAI and xAI on the receiving end. The agency notes that this money will be used to "develop agentic AI workflows across a variety of mission areas." In other words, this is primarily for military applications. A press release says the move will "broaden" the

Why I recommend this Samsung Galaxy Watch over competing Androids

ZDNET's key takeaways The 47mm Samsung Galaxy Watch Ultra normally retails for $650 on Amazon, although it occasionally goes on sale. It's a stylish-looking smartwatch with a slew of safety features and a long-lasting battery. However, it's only available in a single size (47mm, to be exact), meaning it may not be a good fit for folks with smaller wrists. $419.99 at Amazon Samsung's Galaxy Watch Ultra is the company's top-of-the-line wearable, sporting a tough exterior, an eye-catching design

AI slows down open source developers. Peter Naur can teach us why

AI slows down open source developers. Peter Naur can teach us why. AI slows down open source developers. Peter Naur can teach us why. Metr recently published a paper about the impact AI tools have on open-source developer productivity1. They show that when open source developers working in codebases that they are deeply familiar with use AI tools to complete a task, then they take longer to complete that task compared to other tasks where they are barred from using AI tools. Interestingly the

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

Zac Kew-Denniss / Android Authority As a big fan of flip phone foldables, the new Galaxy Z Flip 7 looks like a phone I’ve been wanting from Samsung for years. Samsung’s Z Flip handsets have always been a safe choice in the flip phone market, but the Flip 7 looks like a truly exciting one. Between the vastly improved cover screen, larger main display, and slimmer design, it’s an impressive piece of kit. But for everything Samsung seems to have gotten right with the Z Flip 7, I do have some conc

Malicious VSCode extension in Cursor IDE led to $500K crypto theft

A fake extension for the Cursor AI IDE code editor infected devices with remote access tools and infostealers, which, in one case, led to the theft of $500,000 in cryptocurrency from a Russian crypto developer.

A Clear Sign Just Emerged That Tesla Is Panicking

Tesla sales are so abysmal in Canada that Elon Musk has made the drastic choice to dramatically lower the price of the new Model Y as it attempts to climb out of the hole. As Electrek reports, a Model Y in Canada now costs $65,ooo CAD ($47,465 USD), which is a cool $20,000 CAD cheaper than it was just a few days prior. We'll get into the hows and whys in a second, but first some backstory. Earlier this year, after Trump raised the specter of tariffs against its northern neighbor, Canada moved

Xbox Ally X and Ally leaked prices make the Steam Deck sound like a steal

TL;DR The prices for Xbox’s upcoming handhelds may have leaked. The most expensive model may cost €899, while the cheaper model is said to be €599. While the metadata was scraped from ASUS’ website, these prices could just be place holders. Earlier this year, leaks suggested Xbox was partnering with ASUS to release a handheld under the Xbox brand. A month ago, the company finally confirmed the collaboration during its summer showcase, unveiling two models: the ASUS ROG Xbox Ally X and ROG Xbo

Google’s Pixel 8 Pro is $599, and includes a free Pixel Watch 2

Pricing May Doom Asus’ Xbox Ally Handheld Before It Even Gets a Fair Shot

There hasn’t been any truly new Xbox console hardware in five years. Instead, the first real novel Xbox device isn’t made by Microsoft at all. Asus is designing a new handheld that looks like an Xbox controller split in half with an added screen. While Microsoft has reportedly delayed its own first-party handheld PC, it will need to rely on hardware partners like Asus to push its grand new vision for Xbox hardware. If Microsoft wants it to be a success, it needs to ensure people can actually aff

Sony’s Best-in-Class ANC Headphones May Have a Major Design Flaw

Sony’s WH-1000XM6 headphones might sound great, but that’s only if they don’t break before you put them on your head. While it’s too early to say whether Sony’s latest world-class headphones have a widespread issue, the first reports of broken hinges are starting to roll in, and they feel ominously reminiscent of similar problems with the WH-1000XM5. See Sony WH-1000XM6 at Best Buy In a Reddit thread that’s actually pulled from a Red Note post (sorry for the convolution; that’s just the way li
