WebApr 11, 2024 · Atomic spectroscopy is used to search for the space-time variation of fundamental constants which may be due to an interaction with scalar and pseudo-scalar (axion) dark matter. In this letter, we study the effects which are produced by the variation of the nuclear radius and electric quadrupole moment. The sensitivity of the electric … WebOct 15, 2024 · The standard model of modern cosmology is unthinkable without dark matter, although direct detections are still missing. A broad perspective of how dark matter was postulated and became accepted is presented, from prehistory, over observations of galaxy clusters, galaxy rotation curves, the search for baryonic dark matter, possible …

Web1 day ago · But while dark matter provides gravity to pull the universe together, an equally mysterious force — dark energy — is pulling it apart. “We know even less about dark energy than we do about dark matter,” Nord explains. ... Physics may not have granted Nord flight or X-ray vision — not yet, at least. But over the course of his long ... WebPhysicists have established that dark matter must have mass and exert gravity, but it must also be relatively slow-moving, and its interactions (other than gravity) with known particles must be weak or absent. cf2000a

WebDark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. Dark matter is called "dark" because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect, or emit electromagnetic radiation and is, therefore, difficult to detect. Various astrophysical … Web6 hours ago · A quantum-based theory can also help explore the origin of the matter-antimatter asymmetry or the nature of dark matter and dark energy – phenomena that cannot be explained within the Standard Model.
