In cosmology, primordial black holes (PBHs) are hypothetical black holes that formed soon after the Big Bang.

2019年7月10日 · Primordial black holes could be a type of dark matter called MACHOs, which stands for massive compact halo objects, because astronomers think they’re found in the halos, or outskirts, of...

2024年12月2日 · Set to be published in the December issue of Physics of the Dark Universe and available online now, the theoretical study posits that a primordial black hole trapped within a large rocky object out in the cosmos would consume its liquid core and leave it hollow.

2025年1月13日 · The largest of the primordial black holes might resolve another open question: how supermassive black holes, especially those detected early in the universe, could have grown so big so quickly ...

2022年11月10日 · Abstract: Aspects of primordial black holes, i.e. black holes formed in the early Universe, are reviewed. Special emphasis is put on their formation, their r{ô}le as dark matter candidates and their manifold signatures, particularly through gravitational waves.

2024年5月7日 · Today, black holes form either when a massive star collapses or when heavy objects merge. However, scientists suspect that smaller “primordial” black holes, including some with masses similar to Earth’s, could have formed in the first chaotic moments of …

2024年12月2日 · New research co-led by the University at Buffalo proposes thinking both big and small to confirm their existence, suggesting that their signatures could range from very large—hollow planetoids in...

2021年12月16日 · How did supermassive black holes form? What is dark matter? In an alternative model for how the Universe came to be, as compared to the ‘textbook’ history of the Univers , a team of astronomers propose that both of these cosmic mysteries could be explained by so-called ‘primordial black holes’.

2024年12月6日 · New theoretical research explores innovative methods to detect primordial black holes, suggesting that signatures of these elusive objects could range from hollow planetoids in space to microscopic tunnels in earthly materials.

We overview the history of primordial black hole (PBH) research from the first papers around 50 years ago to the present epoch.
