📌 MAROKO133 Eksklusif ai: Astronomers Spot Something "Totally Unexpected&quot

A supermassive black hole lurking at the center of M87, a supergiant galaxy 55 million light-years from Earth, is acting far more strangely than anticipated.

Since 2017, astronomers from the Event Horizon Telescope (EHT) — an international collaboration combining a global network of radio telescopes — have closely watched the enormous gaping maw, resulting in the first-ever images of a black hole ever captured by humankind.

Now, by comparing observations from 2017, 2018, and 2021, scientists made a surprising discovery about how the magnetic fields near the black hole, dubbed M87*, change over time.

As detailed in a new paper published in the journal Astronomy & Astrophysics, an international team of astronomers discovered that the black hole’s polarization flipped between 2017 and 2021, raising the possibility of a complex internal magnetic structure near its event horizon, the boundary in space beyond which nothing, even including light, can escape.

The findings suggest that magnetic fields play a significant role in how matter gets sucked up into the black hole and how energy gets spat back out, while also highlighting how much there’s still to learn about these cosmic monstrosities.

“What’s remarkable is that while the ring size has remained consistent over the years — confirming the black hole’s shadow predicted by Einstein’s theory — the polarization pattern changes significantly,” said coauthor and Harvard astronomer Paul Tiede in a statement. “This tells us that the magnetized plasma swirling near the event horizon is far from static; it’s dynamic and complex, pushing our theoretical models to the limit.”

Thanks to many improvements and instrument upgrades to the EHT project, scientists now have a smorgasbord of new data to examine that “will certainly keep us busy for many more years,” co-lead and Radboud University Nijmegen assistant professor Michael Janssen added.

According to the analysis, M87*’s polarization pattern flipped between 2017 and 2021, which “was totally unexpected,” as coauthor and Kyunghee University astronomer Jongho Park put it in the statement.

The finding “challenges our models and shows there’s much we still don’t understand near the event horizon,” he added.

Thanks to several new telescopes that were added to the EHT’s global network in 2021, the team was able to examine the spiraling, jet-like beams of energetic particles leaving M87* at almost the speed of light.

This enhanced sensitivity allowed them to detect “subtle polarization signals,” as coauthor and Max Planck Institute for Radio Astronomy postdoctoral researcher Sebastiano von Fellenberg explained in the statement.

The scientific community is celebrating the latest findings as a major breakthrough in our understanding of black holes.

“These results show how the EHT is evolving into a fully fledged scientific observatory, capable not only of delivering unprecedented images, but of building a progressive and coherent understanding of black hole physics,” said University of Naples Federico II astronomy professor and EHT project scientist Mariafelicia De Laurentis.

“It is a concrete demonstration of the extraordinary scientific potential of this instrument,” she added.

📌 MAROKO133 Hot ai: Meta's Disastrous Smart Glasses Demo Even Worse Than We T

Mark Zuckerberg’s MetaConnect 2025 keynote on Wednesday quickly turned into a humiliating experience.

The company’s demos of its new artificial intelligence-powered smart glasses failed repeatedly, causing Zuckerberg to stammer his way through awkward silences.

“This is, uh… it happens,” the CEO stammered after his smart glasses refused to accept a WhatsApp video call on stage. “Let’s try it again, I keep messing this up.”

Another demo involved content creator and amateur chef Jack Mancuso trying to get assistance from his AI glasses while cooking up a steak sauce. But the segment devolved into confusion as the “Live AI” feature assumed he was far more along in the process than he actually was, the kind of hallucination you’d expect from an AI assistant.

“You already combined the base ingredients,” the AI told Mancuso, who was sheepishly standing in front of an empty glass bowl.

It was an embarrassing display, highlighting some glaring shortcomings with the company’s efforts to infuse its Ray-Ban smart glasses with a heavy dose of AI.

Afterward, in an ask-me-anything on Instagram, Meta’s CTO Andrew Bosworth explained what went wrong, insisting that it was a “demo fail, not a product fail.”

“When the chef said, ‘Hey Meta, start Live AI,’ it started every single Ray-Ban Meta’s Live AI in the building,” he said. “And there was a lot of people in that building.”

“That obviously didn’t happen in rehearsal,” Bosworth said. “We didn’t have as many things.”

It wasn’t the only major blunder Meta encountered during its keynote.

Since Meta routed all traffic to its “dev server,” including from all of the headsets in the building, “we DDoS’d ourselves, basically,” Bosworth admitted, referring to a common cyberattack strategy known as a “denial-of-service attack” that attempts to bring a network down by overwhelming it with phony internet traffic.

Bosworth also attempted to explain why Zuckerberg’s attempt to make a WhatsApp video call using the Meta Ray-Ban Display smart glasses completely failed.

Apparently, it was due to a “never-before-seen bug” that Zuckerberg was unable to accept calls on his smart glasses.

“You guys know we can do video calling,” Bosworth pleaded on Instagram. “We got WhatsApp, we know how to do video calling.”

But should we really take the CTO’s excuses at face value? Besides coping with the seemingly inevitable software bugs, there’s a decent chance users of Meta’s smart glasses will also run into a plethora of hallucinations — a reality numerous AI gadget manufacturers have faced already.

In other words, instead of being lied to by an AI on a desktop computer or smartphone, Meta is opening up the possibility of having a robotic voice mislead you straight through your smart glasses as well.

Whether that kind of potential frustration is worth $379 for the regular smart glasses — and $799 for a version of the Ray-Bans with a small screen that wearers can see in their vision — remains to be seen.

On the other hand, journalists who got the opportunity to try the glasses out for themselves appear to have been surprisingly impressed by the experience. So maybe Zuckerberg’s disastrous keynote was just the result of poor planning after all.
