It takes deep, below-the-navel brazen audacity to take on Google in online search.

How a mysterious particle could explain the Universe’s missing antimatter

arstechnica.com Unknown 2025-11-18 16:15:17

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current theories, matter and its counterpart, antimatter, ought to have been created in equal amounts at the time of the Big Bang. But antimatter is vanishingly rare in the universe. So what happened? Physicists don’t know the answer to that question yet, but many think the solution must involve some subtle dif

Model intelligence is no longer the constraint for automation

news.ycombinator.com Unknown 2025-11-18 21:44:49

The perception is that model improvement seems to be stagnating. GPT-5 wasn’t the step change that people were expecting. Yet, models continue to improve on reasoning benchmarks. Recently, both OpenAI and Google models were on par with gold medallists in the International Mathematical Olympiad 2025 (IMO). At the same time it’s still difficult to make AI agents work for relatively simple enterprise use cases. Why is there such a disparity in model performance between problem domains? Why are mode

SpaceX is continuing with final preparations for the 10th full-scale test flight of the company's enormous Starship rocket after receiving launch approval Friday from the Federal Aviation Administration. Engineers completed a final test of Starship's propulsion system with a so-called "spin prime" test Wednesday at the launch site in South Texas.

SpaceX Has Likely Skirted Federal Income Taxes for Decades, Investigation Reveals

Since its founding in 2002, Elon Musk’s SpaceX has emerged as the leading force in commercial spaceflight and a key launch provider for the U.S. government. A recent investigation suggests its dominance may stem—at least in part—from two decades of federal tax avoidance. Internal company documents reviewed exclusively by The New York Times show that SpaceX can exploit net operating loss (NOL) carryforwards, a U.S. tax provision that lets companies use past losses to offset future taxable income

Earlier this year, Nintendo helped popularize the microSD Express standard by requiring it for the new Switch 2 console. Created in 2019, the specification had languished in relative obscurity for years because the cheap, plentiful non-Express microSD cards were generally fast enough for the things that people were using them for, and because most hardware didn't support microSD Express cards in the first place.

Trump Rips Up Environmental Rules Protecting Wildlife From Destructive Rocket Launches

Their friendship may be over, but president Donald Trump just handed Elon Musk and his company SpaceX a major boon by brushing aside major environmental regulations.

As part of this push, the Federal Aviation Administration is directed to "eliminate or expedite" environmental reviews — an obstacle that has been a persistent thorn in Musk's side.
