I find all these constructions very interesting, and this latest one is very interesting as well.” Supermazes would inhabit black holes that weren’t truly black holes. Instead they’d be fuzzballs: ...

While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and slowly ...

Quasars are distant galaxies ... X-Ray Flashes from a Nearby Supermassive Black Hole Accelerate Mysteriously Jan. 13, 2025 — Astronomers observed flashes of X-rays coming from a supermassive ...

This black hole is about 400 million times the mass of the Sun, making it one of the biggest ever spotted at this early point in cosmic history. What’s even more startling is its relationship ...

"Our findings pave the way for rigorous examinations of black holes and the exploration of new physics in gravity." Cosmic echoes from some of the universe's most violent collisions are far more ...

Black holes are bounded by outer barriers called event horizons that prevent us from ever viewing their interiors or their hearts, singularities at which all known laws of physics collapse.

After decades of inactivity, the black hole at the galaxy's heart burst with light. Now, the cosmic monster appears to be doing something that is forcing astronomers to re-evaluate their ...

A massive black hole at the heart of a galaxy in the Virgo constellation is waking up, shooting out intense X-ray flares at regular intervals that have puzzled scientists, a study said Friday.

What if everything we know—the stars, the galaxies, the expanding fabric of space-time—isn’t floating in a limitless void, but instead exists inside a black hole? It may sound like a work of ...

A scientist from Tokyo Metropolitan University has solved the longstanding problem of a "dissonance" in gravitational waves emitted by a black hole. Using high precision computing and a new ...
