Black Hole

Solving the equations of general relativity for colliding black holes is no simple matter. Physicists began using supercomputers to obtain solutions to this famously hard problem back in the 1960s. In 2000, with no solutions in sight, Kip Thorne, 2018 Nobel Laureate and one of the designers of LIGO, famously…

SummaryAs children once did before Christmas, astrophysicists have been eagerly awaiting the arrival of a catalog, this one listing not toys, but cataclysmic collisions of objects such as black holes—the ghostly ultraintense gravitational fields left behind when massive stars collapse. Last week, it arrived, courtesy of the world's network of…

I’m a compulsive journal-scribbler. This habit, which goes back to my teens, has proved useful to my career. All my articles and books start as journal entries. But my motivation is not merely professional. If I don’t record my thoughts, I won’t remember them, and they won’t matter. So I…

Abstractions blogBy Adam MannNovember 3, 2020 Once missing in action, middleweight black holes have finally been detected. Now researchers are trying to figure out how they grow from small ones. Samuel Velasco/Quanta Magazine Until recently, black holes — those celestial spheres so dense that not even light can escape their…

Curated by MyScienceShop, the online store of Discover, this list of geek gifts for space lovers will leave any science buff captivated, kind of spooked, and curious about black holes. Black holes have hijacked the attention of science geeks everywhere. Give the gift of eternal exploration. 1. The Space &…

Home News (Image: © Brian Christensen/Stocktrek Images) Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole. Black holes – regions in space where gravity is so strong that nothing can escape – are a hot topic…

After getting…

SERIESHidden StructureBy George MusserOctober 29, 2020In a landmark series of calculations, physicists have proved that black holes can shed information, which seems impossible by definition. The work appears to resolve a paradox that Stephen Hawking first described five decades ago. In a series of breakthrough papers, theoretical physicists have come…
