Physicists have built the first ever black hole bomb, a long-theorised phenomenon where energy is boosted by a black hole and trapped by surrounding mirrors until an explosion occurs. Thankfully ...

Astronomers confirm a wandering black hole in our galaxy’s Sagittarius region using Hubble and Gaia microlensing data.

While it's much smaller than the largest supermassive black holes detected, it's still a whopper considering how early in the history of the universe it appeared. An enormous black hole in the ...

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 ...

They suggested it might be a lone black hole. Shortly thereafter, a second research team challenged that result, suggesting it was more likely a neutron star. After continuing to study the object ...

A Michigan State University researcher saw X-rays coming from a black hole using the NASA Chandra X-Ray Observatory telescope. "Every large galaxy has a supermassive black hole, but the exact ...

Dark matter may have contributed to the formation of giant black holes in the early universe, researchers propose in a new paper. More observations, especially with the James Webb Space Telescope ...

Another idea, first proposed by respected physicist and mathematician Roger Penrose, is that we could extract energy from rotating black holes, also known as Kerr black holes, after Roy Kerr ...

While he offers several explanations for what could cause the universe to rotate, he focuses mainly on the hypothesis that it is inside a gigantic black hole. Because black holes naturally rotate ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...
