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 new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into ...

The universe is overrun with dark matter, outweighing the ordinary stuff that stars and planets are made of five-to-one. But ...

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.

Since Thread and Matter are two different things, they can exist without each other. However, products that are built to support both are referred to as Matter over Thread, where Matter is the ...

Dark matter will help explain not only how our universe was made, but also its components. It will help people understand fundamental physics and how additional particles and forces exist. The ...

David Joffe receives funding from NASA through a grant from the Georgia Space Grant Consortium. Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer ...

At the center of our galaxy, something incredibly heavy is pulling the strings. Stars there swing around it at breakneck speeds, gas heats up and glows, and even light itself seems to bend. For years, ...

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