How does a black hole generate a magnetic field and how can it be measured and visualized? Alan CroftSeattle, Washington As ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

An illustration of two stellar-mass black holes merging in the accretion disk of an active galactic nucleus. (Shu-Rui Zhang) ...

The study of black holes has long been at the forefront of gravitational physics, and recent advances have significantly enriched our understanding of these enigmatic objects within the framework of ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...

They’re the boogeymen of science fiction, a paradox of science and quite possibly a key to understanding the universe. Scientists have been scrambling to understand the mysterious forces of black ...

Ten years ago, astronomers made history when they first detected ripples in spacetime, called gravitational waves, from the collision of two black holes. That moment in 2015, known as GW150914, ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

But we have no reason to think they exist right now.” A black hole is an area in space that has gobs of gravity. We’re ...

University of Oregon astronomer Yvette Cendes made a surprising discovery years after a black hole shredded a star. What is "Jetty McJetface"?

Between May 2023 and January 2024, a global network of gravitational-wave detectors picked up 128 new cosmic signals, more ...
