What is the Cold Dark Matter Theory?
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.
Dark Matter Theory refers to the extensive framework that encompasses various particles beyond the conventional CDM or WIMP dark matter models. It involves studying the effects of dark sector physics on astrophysical structures to understand the properties and nature of dark matter through theoretical predictions and astronomical observations.
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,...

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. Learn more.
Oct 1, 2024 · Dark matter’s existence was first inferred by Swiss American astronomer , who in 1933 discovered that the mass of all the stars in the Coma cluster of galaxies provided only about 1 percent of the mass needed to keep the galaxies from escaping the cluster’s gravitational pull.
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.
