Webb15 okt. 2024 · This dark-matter-free model is an extension of the so-called MOND (modified Newtonian dynamics) theory, which assumes that the gravitational force on galaxy scales is different from the standard Newtonian force. Previous MOND-based models could not reproduce the CMB. The researchers say that their model can be … Webb11 apr. 2024 · Dark matter is still theoretical since it only seems to interact with gravity while somehow avoiding nature’s other electromagnetic forces. Its lack of interaction with light gives the stuff its name since dark matter is something we cannot directly observe.

Webb28 juli 2024 · Another set of dark matter theories that many scientists consider to have fallen short is modified Newtonian dynamics (or “MOND”). These theories propose a modification to Newton’s laws of motion that would apply only at very small accelerations, which would adequately explain the abnormal rotation speed of galaxies. WebbDark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. [1] Dark matter is called "dark" because it does not appear to …

Dark matter makes up 85% of the universe and is hard to detect because it only interacts with gravity and not with light or other electromagnetic radiation. To track down dark matter, scientists observed ... WebbSo, because of the effects of gravitational lensing, we know there’s something else bending the light, which is thought to be dark matter. Yes, or more precisely, we know there's more mass than the luminous component that we see.
