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 … Webb3 juni 2024 · Particle physicists and theorists are comfortable with the idea that the energy of a particular field must be transmitted by its force particle instead of by the field itself. This concept can be translated to dark energy, with dark matter (the other 27 percent of the universe) being its force particle. [6]
