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

news.ycombinator.com Charlie Wood 2025-09-24 19:27:12

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

Exploding Primordial Black Holes Could ‘Rewrite the History of the Universe’

gizmodo.com Gayoung Lee 2025-09-28 17:40:17

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. In a paper published September 9 in Physical Review Letters, a team of physicists make the bold prediction that, within the next decade, we will be able to w

Scientists Discover Black Hole Created Less Than One Second After the Big Bang

futurism.com Unknown 2025-10-06 04:45:29

Astronomers examining data from the James Webb Space Telescope say they've spotted what might be the oldest black hole in the universe, born less than a second after the Big Bang. Their findings, published in a new study awaiting peer review, could offer the best evidence yet of the existence of what's known as a primordial black hole, a hypothetical object that's divided scientists for decades. Potentially far smaller than their modern counterparts — perhaps as tiny as a planet or even an ato

Black Holes Are the Elusive Source of the Universe’s Dark Energy, Study Argues

gizmodo.com Gayoung Lee 2025-10-29 12:25:46

Dark energy—the hypothetical force accelerating our universe’s expansion—sometimes raises more questions than it answers. A new study, however, presents surprising evidence that black holes may be an incubator for dark energy—suggesting that the force may be less constant than we believed. In a paper published August 21 in Physical Review Letters, researchers used data from the Dark Energy Spectroscopic Instrument (DESI) to test a hypothesis that argues black holes convert dead star matter into

Scientists have recreated the Universe's first molecule

Immediately after the Big Bang, which occurred around 13.8 billion years ago, the universe was dominated by unimaginably high temperatures and densities. However, after just a few seconds, it had cooled down enough for the first elements to form, primarily hydrogen and helium. These were still completely ionized at this point, as it took almost 380,000 years for the temperature in the universe to drop enough for neutral atoms to form through recombination with free electrons. This paved the way

Radical New Theory Rewrites the Story of the Earliest Universe

gizmodo.com Gayoung Lee 2026-01-02 17:05:38

Following the Big Bang, our universe expanded at an exponential rate. According to this theory, known as cosmic inflation, the explosive growth produced tiny quantum fluctuations that later evolved into galaxies. Cosmic inflation neatly explains how our universe got so large and mostly homogenous, and that’s why it’s remained a strong theory in cosmology for decades. But it’s far from perfect. Cosmic inflation depends on certain theoretical assumptions that can get rather arbitrary—not ideal fo

CERN Physicists Find Key Piece of the Matter-Antimatter Puzzle

All matter in our universe has an evil twin: antimatter. Cosmological models suggest that the Big Bang should have created equal amounts of matter and antimatter that cancel each other out. But for reasons physicists still aren’t completely sure about, that didn’t happen. As a result, our universe today hosts slightly more matter than antimatter—our very existence being clear, physical proof. Now, we might be one step closer to explaining why there’s an imbalance between matter and antimatter,

Images of the cosmos, such as the James Webb Space Telescope’s deep space snapshot, make space look chock-full of stuff. In the grand scheme of things, it is, but all those stars, galaxies, planets, and other celestial objects may not be as uniformly distributed as photos make them look. The fact is, space is likely peppered with bubbles of relative emptiness, and some astronomers believe we’re sitting inside of one.

If the lineages are followed back beyond the origin of life on Earth to the origin of the universe, it would be logical to assume that the memory of the universe was lower in the past, which means that the universe's ability to generate objects of high Assembly is limited by its size in time.

Research suggests Big Bang may have taken place inside a black hole

The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from something else – something more familiar and radical at the same time?
