Recent research indicates that dark matter fills what was previously thought to be empty space in the universe, challenging long-held beliefs about cosmic voids. Cosmologists have found that intergalactic space is not devoid of matter but is instead permeated by dark matter, which plays a crucial role in gravitational interactions. Discussions around the deformation of continuous media suggest that the presence of dark matter influences the geometry of spacetime, particularly in relation to baryonic matter. The Milky Way's dark matter halo is described as a state of displacement of dark matter, further complicating our understanding of cosmic structures. This evidence supports the notion that there is no truly empty space in the universe, as all regions are filled with some form of energy density.
