Something Extremely Strange Is Happening at the Event Horizon of This Supermassive Black Hole

In 2019, scientists unveiled the first-ever images of a black hole, M87*. Those observations kickstarted a wave of new investigations into how black holes work, how they grow, and how they change. And now, after a few upgrades, the Event Horizon Telescope network is back with another bombshell centered on M87*—finding tantalizing evidence of previously unknown physics at the event horizon of the black hole itself.

Scientists Detect Strange Signal in Gravitational Waves

For the first time, astrophysicists have measured the recoil — or "kick," in the parlance — resulting from the birth of a new black hole that formed from the merger of two preexisting ones. The international team of researchers measured the ripples in the fabric of spacetime, known as gravitational waves, allowing them to get unprecedented insights into the turbulent dynamics of two black holes crashing into each other. The team analyzed data collected by the Advanced LIGO and Virgo gravitatio

A single, 'naked' black hole confounds theories of the young cosmos

news.ycombinator.com Charlie Wood 2025-09-29 04:27:12

A black hole unlike any seen before has been spotted in the early universe. It’s huge and appears to be essentially on its own, with few stars circling it. The object, which may represent a whole new class of enormous “naked” black holes, upends the textbook understanding of the young universe. “This is completely off the scale,” said Roberto Maiolino, an astrophysicist at the University of Cambridge who helped reveal the nature of the object in a preprint posted on August 29. “It’s terribly ex

Scientists Say They Can't Explain the Signal They Just Detected From Beyond Our Galaxy

futurism.com Unknown 2025-09-29 03:15:24

Gamma ray bursts are some of the most powerful explosions in the universe, unleashing as much energy in mere seconds as the Sun will in its entire 10 billion year lifespan. Typically, they're produced by stars dying in a spectacular supernova — a rapid collapse that completely obliterates the stellar object. But now, astronomers say they've detected a gamma ray burst that utterly defies explanation: it repeated multiple times over the course of a single day, as if the star somehow suffered back

New black hole merger bolsters Hawking area theorem

arstechnica.com Unknown 2025-10-02 14:41:19

Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, the newly formed black hole will have a larger surface area. This became known as Hawking's area theorem. Analysis of the gravitational signal from a black hole merger detected in January provides the best observational evidence to date in support of Hawking's theorem, according to a new paper publis

It’s been a fantastic week for Stephen Hawking’s black hole theories. Yesterday, LIGO confirmed the famed physicist’s prediction about black hole mergers. Now, another team believes they’ve found a way to observe primordial black holes—cosmic behemoths that emerged not from the ashes of dying stars but from the chaos of the early universe.

Scientists Say Black Holes Could Form Inside Planets, Leading to Absolute Catastrophe

Astrophysicists find no 'hair' on black holes

news.ycombinator.com Matt Von Hippel 2025-10-27 13:40:08

According to Albert Einstein’s general theory of relativity, the behavior of a black hole depends on two numbers: how heavy it is, and how fast it is rotating. And that’s it. Black holes are said to have “no hair” — no features that distinguish them from their fellows with the same mass and spin. With new data, it has started to become possible to test this no-hair conjecture. Astronomers have detected hundreds of signals from colliding black holes over the past 10 years.
