Apr 15, 2024 · The only rule of physics that dark matter seems to follow is gravity: It has mass, apparently, and that mass has gravity and forms a vital part of the scaffolding of galaxies, galaxy clusters,...

Dark matter candidates arise frequently in theories that suggest physics beyond the Standard Model, such as supersymmetry and extra dimensions. One theory suggests the existence of a “Hidden Valley”, a parallel world made of dark matter having very little in common with matter we know.
Oct 1, 2024 · dark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).

Sep 23, 2024 · Theoretical physicist Tracy Slatyer proposes new scenarios for dark matter and helped discover the Fermi bubbles.
Matter is defined as any substance that has mass and occupies space. But there’s more to the universe than the matter we can see. Dark matter and dark energy are mysterious substances that affect and shape the cosmos, and scientists are still trying to figure them out.
Scientists are trying to determine what dark matter is made of, but our current understanding has many gaps. Roman will provide clarity by exploring the structure and distribution of both normal matter and dark matter across space and time.
Nov 5, 2020 · Dark matter doesn’t emit, reflect, or absorb light, making it essentially invisible to current instruments. Researchers instead infer things about dark matter through what its powerful gravity allows it to do: bend and focus the light around it, a phenomenon called gravitational lensing.
