Portsmouth大学宇宙学与引力研究所和巴塞罗那空间科学研究所的研究人员提出了一项新的宇宙起源模型，认为存在于大爆炸之前的黑洞可能以"宇宙化石"的形式延续至今，从而解释暗物质的本质1。该研究由Enrique Gaztañaga教授主导，已于2026年8月11日发表在《Physical Review D》期刊上1。
这一理论基于量子物理学原理，提出宇宙并非源于单一奇点的爆炸，而是从先前收缩阶段的反弹中产生1。根据该模型，约90米以上尺寸的物体能够穿过这次宇宙反弹过程1，原始黑洞作为这样的大质量天体得以保存。研究人员指出，这一假说有助于解释为何超大质量天体在宇宙早期即已出现1。鉴于暗物质的质量超过普通物质约5倍1，这些来自前宇宙时代的黑洞可能构成了观测到的暗物质的主要成分。
Researchers at the University of Portsmouth have proposed a novel cosmological model suggesting that black holes existing before the Big Bang may have survived to the present day as "cosmic fossils."1 According to the theory, these primordial black holes could account for the nature of dark matter and shed light on why supermassive objects emerged so early in cosmic history.1
The study, led by Professor Enrique Gaztañaga and published in Physical Review D on August 11, 2026, is based on quantum physics principles positing that the universe rebounded from a contracting phase rather than originating from a singularity.1 The research, conducted jointly by the University of Portsmouth's Institute of Cosmology and Gravitation and the Barcelona Space Sciences Institute, challenges the conventional understanding of cosmic origins.1 According to the model, "the universe may not have begun with a single explosion, but rather emerged from a cosmic bounce."1 Objects capable of passing through the bounce had a size threshold of approximately 90 meters, the researchers noted.1
The framework offers a potential explanation for observations made by the James Webb Space Telescope of mysterious early-universe phenomena termed "red dots."1 Given that dark matter constitutes more than five times the mass of ordinary matter in the universe, and the cosmos is approximately 13.8 billion years old, the discovery of a mechanism to account for dark matter's composition holds significant implications for cosmological understanding.1
