A good chunk of cosmology is riding on whether dark matter exists or not. But what makes us so certain that dark matter is ...
A new kind of dark matter could help explain some of the universe’s mysteries, a new study suggests. The study proposes that there are dense clumps of “self-interacting dark matter”, or SIDM, each ...
A quiet shift in the numbers behind the universe’s growth is pushing scientists toward a bold possibility. Two of the cosmos’ most elusive players, dark matter and neutrinos, may not be strangers ...
A group of undergraduate students pulled off something remarkable: they built their own dark matter detector and used it to ...
Dark matter is some kind of substance that has gravity—it holds galaxies together—yet cannot be directly seen with any instrument yet created. We know it’s out there because of the effects it has on ...
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 ...
Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass. Because it’s so abundant, astronomers believe it should explain many unsolved ...
The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark ...
Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to anchor our galaxy, explaining both the blistering speeds of stars near the ...
