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.
