一项发表在《宇宙学和天体粒子物理学杂志》2026年第06期的研究表明，暗物质粒子之间可能存在隐藏力相互作用，但其作用机制与科学家原来的预期截然相反[1]。这种额外的吸引力虽然能使暗物质聚集更为有效，但在宇宙膨胀的过程中却会使暗物质的有效质量减轻，从而削弱其引力影响[1]。这通常会抑制而非加速宇宙大尺度结构的增长[1]。
研究团队包括Marco Costa、Cyril Creque-Sarbinowski、Olivier Simon和Zachary J. Weiner，其中Weiner来自圆周物理研究所[1]。该研究基于暗能量光谱仪（DESI）的最近测量结果进行分析[1]。
Weiner表示，"我们对暗物质的了解迄今为止只是通过其引力效应学到的"[1]，并指出"宇宙通常比我们的直觉更微妙，这正是为什么我们必须继续测试这些想法"[1]。
Researchers have discovered that dark matter particles may interact through a hidden force with counterintuitive effects, according to new findings published in the Journal of Cosmology and Astroparticle Physics in June 2026 [1]. The study, conducted by Marco Costa, Cyril Creque-Sarbinowski, Olivier Simon, and Zachary J. Weiner of the Perimeter Institute for Theoretical Physics, reveals that while this additional attractive force makes dark matter cluster more efficiently, it simultaneously reduces dark matter's effective mass as the universe expands [1]. This weakening of gravitational influence typically suppresses rather than accelerates the growth of large-scale cosmic structures, contrary to what scientists had anticipated [1].
The research builds upon recent measurements from the Dark Energy Spectroscopic Instrument (DESI) [1]. Weiner emphasized the limitations of current understanding, noting that "what we have learned about dark matter so far has been only through its gravitational effects" [1]. He further reflected on the nature of cosmic phenomena, stating that "the universe is often more subtle than our intuition, which is why we must continue to test these ideas" [1].
