No trace of dark matter halos
No trace of dark matter halos
Signs of disturbance in the dwarf galaxies of one of Earth's nearest galaxy clusters indicate an alternative gravity theory According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity.
