📌 MAROKO133 Eksklusif ai: Scientists Intrigued by Black Hole That Fell Into Star,

This summer, astronomers detected a gamma ray burst (GRB) so powerful that they’re still struggling to explain what caused it. These cosmic explosions are typically produced by stars dying in a spectacular supernova, unleashing in moments as much energy as the Sun will over its entire lifetime.

But this new one, dubbed GRB 250702B, blows everything we know about these fearsome blasts out the water. For starters, it lasted a staggering seven hours, which is vastly longer than they typically do. And it also appeared to repeat several times over its run, which shouldn’t be possible. A GRB is produced by the total obliteration of a star, so how could the same source emit multiple blasts?

A wealth of theories have been put forward ever since the detection. But a new one, published in a study slated to be submitted to the journal Monthly Notices of the Royal Astronomical Society, may be the most terrifying yet.

In an inversion of the well known scenario of a black hole devouring a star, the researchers propose that a star actually swallowed a black hole. Once subsumed, the massive infiltrator begins to rip apart the star’s core, then devour the rest of its host from the inside out, producing an incredibly energetic stream of particles called a jet.

“It’s a GRB-like phenomenon, but it allows for the longer time scale,” Daniel Perley, an astrophysicist from the UK’s John Moores University who was not involved in the study, told Science.

Death by black hole is not an unusual fate for a star. The most well known form are tidal disruption events, which occur when a star wanders too close to a supermassive black hole that weighs millions if not billions of solar masses and are often found in the heart of a galaxy. The object’s ungodly gravity shreds the star down into a stream of material as it floats closer. Instead of immediately getting consumed, the spaghettified star dust gets pulled into a swirling disk around the black hole, like water circling a drain, emitting huge amounts of energy.

This latest theory theory to explain GRB 250702B flips the idea on its head in a few ways. Instead of a supermassive black hole, it’s a stellar mass black hole — or a modest-sized black hole that forms from the implosion of a star — which is orbiting another star that’s burned through all its fuel. This moribund star begins to puff out, creating an envelope that’s dwarfs its original size. This tugs on the black hole, causing it to gradually fall into the star’s core. From there, the black hole rips the star apart, creating the lengthy jets that appear to us like a GRB.

“The argument posed in this paper is a very compelling one,” Hendrik van Eerten at the University of Bath in the UK told New Scientist.

The GRB was first detected by NASA’s Fermi Gamma-ray Space Telescope on July 2, appearing as three distinctive bursts. Follow up observations proved that the source was coming from well outside our galaxy, up to billions of light years away, ruling out the possibility that it only appeared so powerful because of its proximity.

Other explanations researchers are considering include a star collapsing under its own weight, or perhaps a tidal disruption event involving an intermediate mass black hole. All of them have glaring issues, though — so the mystery continues to eat astronomers up inside.

📌 MAROKO133 Breaking ai: Crypto Kingpin Turns Up Dead in Lamborghini After Market

The past week has not been kind to blockchain entrepreneurs, whose holdings suffered the largest crypto liquidation in history last Friday, an event which wiped more than $380 billion off the market.

During the short but heavy crash, the price of Bitcoin fell 15 percent, while the second-largest cryptocurrency, Ethereum, dropped some 21 percent. The alt-coin market all but collapsed, many of them falling as much as 80 percent, raising serious doubts about the future of the broader crypto ecosystem.

Depending where you look, crypto prices are already rebounding as investors rush to hedge against another fall. But the recovering wasn’t in swing before Konstantin Ganich, a Ukrainian crypt fund manager and influencer was found dead in his Lamborghini, the victim of a gunshot wound.

Ganich, who was also known as “Kostya Kudo” on social media, was rumored to have lost anywhere from $7 million to $60 million in the crash, according to various Ukrainian media sources. Peter Korotaev, a journalist who runs the English-language blog Events in Ukraine, wrote that “much, if not most” of that money belonged to investors.

According to Korotaev, Ganich had claimed in Ukrainian-language interviews that his crypto holdings were insured for losses up to 15 percent. He added that the crypto tycoon paid investors a fixed monthly sum of 7 percent based on their buy-in, no matter how good or bad the market was doing — a classic hallmark of a crypto scam.

Police initially told news media that the 32-year-old crypto blogger died by suicide. Before his death, Ganich was reportedly depressed about the crypto crash, and sent farewell messages to love ones, per 44, a local news aggregator in Kyiv.

However, according to Ukrainian Independent News Agency (UNINA) — one of the longest-running news agencies in Ukraine — Ganich’s acquaintances allege that law enforcement bureaucrats pressured the crypto trader the night before his death, demanding a share of his income. While not confirmed by state investigators, that allegation was also raised by another news agency, Strana, which added that Ganich was likely managing funds for ranking Ukrainian government and police officials.

Those claims throw an intriguing wrench into the official story, especially given the day-to-day volatility of the crypto trade. As one of Ganich’s associates told UNINA, “if crypto people shot themselves after every market crash, they would all be lying in the ground.”

Throwing even more fuel onto the conspiracy fire, Korotaev writes, is the fact that the victim’s gun was a gift from Kyryllo Budanov, the head of Ukrainian military intelligence described by western researchers as Ukraine’s “top spymaster.” Budanov is known for perpetuating massive call center scams on behalf of the Ukrainian government, among other financial espionage.

Whether by suicide or murder, it’s not out of the realm of possibility that Ganich’s death resulted from his role in the pressure cooker that is the Ukrainian crypto scene. Despite being one of the poorest countries in Europe, Ukraine is one of the world leaders in crypto adoption, with tens of billions of dollars worth of the stuff flowing through the nation every year.

“Political and economic relations in Ukraine at the highest levels are based on corruption,” one crypto investor told Strana. “In recent years, corruption has shifted to cryptocurrency. Cryptocurrency is the main nerve center of all Ukrainian corruption right now.”
