In 2012, physicists showed that this paradox is tightly linked to the nature of the event horizon. They’d known since the 1970s that black holes emit radiation, and that this radiation probably somehow carries the scrambled information about the stuff that fell into the hole. Now they imagined what would happen if an astronaut who was about to cross the …

New research suggests that dark matter could gather over vast periods of time at the heart of Jupiter-sized planets, creating black holes that eat these worlds from within. This striking concept may mean extrasolar planets, or “exoplanets,” could be used to study the mystery of dark matter. In this new model, superheavy dark matter particles could be trapped by exoplanets, …

Exoplanets might hold hidden clues about dark matter. New research suggests these distant worlds could even collapse into black holes, challenging existing theories. Credit: SciTechDaily.com Scientists’ model indicates that dark matter inside gas giants could collapse into black holes detectable by observation. Astronomers have identified more than 5,000 planets orbiting stars outside our solar system. These distant worlds, known as …

The Event Horizon Telescope (EHT) established a reputation worldwide in 2019 when it released the first-ever image of a black hole. This was made possible by the science of Very Long Baseline Interferometry (VLBI), a technique in which multiple instruments collect light to create a complete picture of what an object looks like. In this case, the image was of …

In a new study, scientists began pondering a pretty wild question: What if black holes can convert dead star matter into dark energy, the mystery force driving the acceleration of the expansion of the universe? If so, then it just might explain a multitude of “hiccups” in our models of the universe. This new theory proposes that black holes could …

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 …

In a high-resolution satellite image taken by NASA’s Landsat 8 on May 3, 2016, a series of dark, swirling shapes appeared in the clouds above Heard Island, a remote volcanic island in the Southern Ocean. Located roughly 1,000 kilometers north of Antarctica, this uninhabited landmass became the center of attention after the release of the image revealed what looked like …

Famed YA author Louis Sachar is out with his first novel for adults. Alex Labry/Ace hide caption toggle caption Alex Labry/Ace Louis Sachar, the author of Holes and the Wayside School series, has spent nearly half a century writing books for kids. And he was originally going to continue that streak with his new novel, The Magician of Tiger Castle. …

Scottie Scheffler’s shot looked like one that Hollywood would have concocted for a movie.  But the wild 82-foot chip shot for birdie on the 17th hole Sunday during the final round of the BMW Championship was not the result of a scripted moment, and it helped propel Scheffler to his fifth PGA Tour title of the year.  Scheffler had hit …

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. Black holes are massive, strange and incredibly powerful astronomical objects. Scientists know that supermassive black holes reside in the centers of most galaxies. And they understand how certain stars form the comparatively smaller stellar mass black holes once they reach …
