New research shows a direct interaction between dark matter particles and those that make up ordinary matter.
The Lambda-Cold Dark Matter model , which came to the forefront in the late 1990s, considers various observations of the universe that previously appeared inconsistent and tries to create consensus explanations on the universe's energy breakdown, including the nature and role of dark matter.
The Lambda-CDM model suggests that dark matter particles are slow, cold, and inert and do not interact with other particles other than gravitationally. But suppose the team of scientists behind theis correct. In that case, there are huge, sphere-like regions in distant space, such as at the center of spiral galaxies, that are "taken over" by dark matter particles which directly interact with ordinary matter like protons, electrons, neutrons, and photons.
Spiral galaxies feature a"vast spherical region" of dark matter particles with density that changes as the region expands over time. ViaWhat they found in that central region of these faraway galaxies was unexpected to the scientists and may go against the established notions of the standard model of cosmology.
Such a process could be responsible for the shape and density of the regions observed by the scientists, leading to a potential rethink of what we know about dark matter. Suppose there is an interaction of the kind the paper suggests.
after a prolonged shut down for maintenance to search for dark matter, among other mysterious particles.
