A new candidate for dark matter and a way to detect it

Two theoretical physicists at the University of California, Davis have a new candidate for dark matter, and a possible way to detect it. They presented their work June 6 at the Planck 2019 conference in Granada, Spain and ...

Microscopic wormholes possible in theory

Wormholes play a key role in many science fiction films—often as a shortcut between two distant points in space. In physics, however, these tunnels in spacetime have remained purely hypothetical. An international team led ...

Magnetic monopoles detected in a real magnet for the first time

Researchers from the Helmholtz Centre Berlin, in cooperation with colleagues from Dresden, St. Andrews, La Plata and Oxford, have for the first time observed magnetic monopoles and how they emerge in a real material. They ...

Dark matter might cause fundamental constants to change over time

(Phys.org)—The fundamental constants of nature—such as the speed of light, Planck's constant, and Newton's gravitational constant—are thought to be constant in time, as their name suggests. But scientists have questioned ...
