Long-Lived Stellar Blast Kindles Hope of a Supernova We’ve Never Seen Before
...a preview of how they may have looked and behaved. Perhaps they were also responsible for the first black holes, said Stan Woosley, an astrophysicist at the University of California,...
Cosmic Map of Ultrahigh-Energy Particles Points to Long-Hidden Treasures
...galaxies: objects called active galactic nuclei, or AGNs. AGNs are the white-hot centers of “active” galaxies, in which plasma engulfs the central supermassive black hole. The black hole sucks the...
Topologists Tackle the Trouble With Poll Placement
...time to vote. Empty areas completely surrounded by the shapes are called holes. The holes are where residents would be either making their way to the polls or waiting in...
AI Starts to Sift Through String Theory’s Near-Endless Possibilities
...space-times surrounding exotic black holes. Perhaps, he speculated, computers could also solve for the metrics of Calabi-Yau space-times. “Everyone said, ‘Oh, no, you couldn’t possibly do that,’” Wiseman said. “So...
What Astronomers Are Learning From Gaia’s New Milky Way Map
...massive black hole at the center of the Large Magellanic Cloud. Full-size galaxies almost always harbor huge central black holes, which are of mysterious provenance. Their presence in some mini...
A Jewel at the Heart of Quantum Physics
...quantum field theory enters crisis mode in black holes. Black holes pack a huge amount of mass into an extremely small space, making gravity a major player at the quantum...
Math Duo Maps the Infinite Terrain of Minimal Surfaces
...constructed, offer a lens through which to study the geometry of the surrounding space, and they turn up in a range of scientific settings, from the study of black holes...
Any Single Galaxy Reveals the Composition of an Entire Universe
...The simulations also included rough treatments of complicated events like supernovas and jets that erupt from supermassive black holes. Ding’s neural network studied nearly 1 million simulated galaxies within these...
A New Tool for Finding Dark Matter Digs Up Nothing
...gravitational waves that pass through the planet, created by the distant collisions of black holes, only stretch and compress each mile of Earth’s surface by one-thousandth the diameter of an...
