Researchers have uncovered a concealed force that might affect dark matter, which could lead to a revised understanding of how the Universe develops, challenging prior assumptions regarding the expansion of cosmic structures. A study published in the Journal of Cosmology and Astroparticle Physics reveals that this force not only attracts dark matter particles but also reduces their effective mass over time, diminishing the influence of gravity. The authors of the study suggest that these insights may clarify ongoing discrepancies between measurements of cosmic expansion and observations of large-scale structures, paving the way for novel avenues in cosmological research.
