Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

This video explores the enigma of dark matter, an elusive substance believed to make up most of the universe's matter. While the universe is populated by visible stars and galaxies, much of its mass ...

This brings us a huge leap forward in our understanding of the universe.

A near invisible realm. The post Hubble Spots Bizarre Galaxy That Appears to Be 99.9 Percent Dark Matter appeared first on Futurism.

A galaxy made of 99.94% to 99.98% dark matter immediately challenges and updates models for how dark matter works. It also sheds light on how the universe arrived at the large-sca ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

Our Milky Way galaxy may not have a supermassive black hole at its center but rather an enormous clump of mysterious dark matter exerting the same gravitational influence, astronomers say. They ...

(via Sabine Hossenfelder) Physicists don’t actually know what the universe is really made of. The currently most popular theory is that most of the universe is made of dark matter, a mysterious type ...

This new map is not only the most detailed view of the universe’s invisible scaffolding to date, it also allows astronomers to look deeper into cosmic history. Reading time 3 minutes Dark matter—the ...

The Milky Way — and in fact our entire galactic neighborhood known as the Local Group — appear to be lodged in a vast, extended “sheet” of dark matter flanked on each side by cosmic voids, new ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

A huge clump of dark matter could be sitting on our galactic doorstep. Scientists found evidence of an invisible, massive nugget in the galactic neighborhood of the sun. The suspected clod of dark ...
