Black hole ‘carnivals’ could produce the signals seen by gravitational wave detectors

Artist’s impression of a collection of black holes at the heart of a star cluster. Credit: ESA/Hubble, N. Bartmann Since 2015, the LIGO-Virgo-KAGRA collaboration has detected around 85 pairs of colliding black holes. We now know that Einstein was right: gravitational waves are generated by these systems as they wind around each other, warping spacetime …

Physicists produce symmetry-protected Majorana edge modes on a quantum computer

Physicists produce symmetry-protected Majorana edge modes on a quantum computer

Artistic representation of Majorana edge modes on a string of superconducting qubits. Credit: Google Quantum AI Google Quantum AI physicists have used their quantum computer to study an efficient type of particle that is more resilient to environmental disturbances that can degrade quantum computations. These effective particles, known as Majorana edge modes, form as a …

Alpine villages produce their own electricity

Alpine villages produce their own electricity

Overall, this imbalance between the number of small factories and their overall production is similar. Small generating stations represent about 91% of all hydroelectric installations, but account for only 11% of hydroelectric production. And yet they’ve seen a global boom in recent years – along with a growing body of evidence from around the world …

We Finally Know How Black Holes Produce the Brightest Light in the Universe

We Finally Know How Black Holes Produce the Brightest Light in the Universe

For something that emits no light that we can detect, black holes love to blanket themselves in radiation. In fact, some of the brightest light in the Universe comes from supermassive black holes. Well, not really black holes themselves; it is the material that surrounds them as they actively suck up large amounts of matter …

We Now Know Why Black Hole Jets Produce High-Energy Radiation

Enlarge / The jets of material ejected around black holes can be enormous. Active galactic nuclei, powered by the supermassive black holes they contain, are the brightest objects in the Universe. The light comes from jets of matter projected at a speed close to light by the environment around the black hole. In most cases, …
