英国朴茨茅斯大学的研究团队提出了一项新颖理论，认为存在于大爆炸之前的黑洞可能作为"宇宙化石"存活至今，并可能解释暗物质的本质[1]。这项研究由朴茨茅斯大学宇宙学与引力研究所及巴塞罗那太空科学研究所联合开展，论文作者Enrique Gaztañaga教授在研究中探讨了"宇宙反弹"模型[1]。
根据该模型，宇宙从早期的收缩阶段扩张而来，古老黑洞可能在这一过程中幸存[1]。研究指出，能够存活下来的物体大小约为90米以上[1]。这些原始黑洞的存在或有助于解释早期宇宙中大质量物体的形成，而暗物质比普通物质重5倍左右[1]。Gaztañaga教授表示："如果宇宙确实经历了反弹，那么今天塑造星系的暗结构可能是来自大爆炸之前的宇宙时代的遗迹"[1]。该论文已于2026年8月11日发表在《Physical Review D》第113卷第4期[1]。
Researchers from the University of Portsmouth's Institute of Cosmology and Gravitation and the Barcelona Space Sciences Institute have proposed a novel explanation for dark matter: primordial black holes that may have survived from before the Big Bang itself [1]. The study, led by Professor Enrique Gaztañaga and published in Physical Review D Volume 113, Issue 4 in 2026, explores a "bouncing universe" model in which the cosmos expanded from an earlier contraction phase, allowing ancient black holes to persist through this cosmic transition [1].
According to the research, objects larger than approximately 90 meters could have survived the bouncing process and remained intact to the present day [1]. Dark matter, which outweighs ordinary matter by roughly five times, has long puzzled cosmologists, and these relict black holes from the pre-Big Bang era offer a potential solution to this mystery [1]. Professor Gaztañaga remarked that "if the universe indeed experienced a bounce, then the dark structures shaping galaxies today could be remnants from the cosmic era before the Big Bang" [1].
