New Research Suggests Dark Matter Exerts a Hidden Force with Counterintuitive Effects

Scientists are exploring the possibility that dark matter particles interact through a hidden force beyond gravity. A new study published in the Journal of Cosmology and Astroparticle Physics (JCAP) found that while this additional attractive force helps dark matter cluster more efficiently, it surprisingly tends to slow the growth of cosmic structure rather than accelerating it. This research aims to address discrepancies in observations of cosmic expansion and the development of large-scale structures.
