论文摘要
我们讨论了暗物质与宇宙的熵之间的关系，即暗物质在大众层的层次结构中以原始黑洞（PBH）的形式存在。最轻的层是包括银河系在内的星系中的中间质量PIMBH。银河中心的超质量黑洞位于第二层。我们被猜测，存在第三层非常庞大的PBH，比整个星系更大。我们讨论了鲁宾天文台和詹姆斯·韦伯太空望远镜的未来观察结果。
We discuss the relationship between dark matter and the entropy of the universe with the premise that dark matter exists in the form of primordial black holes (PBHs) in a hierarchy of mass tiers. The lightest tier are intermediate-mass PIMBHs within galaxies including the Milky Way. Supermassive black holes at galactic centres are in the second tier. We are led to speculate that there exists a third tier of extremely massive PBHs, more massive than entire galaxies. We discuss future observations by the Rubin Observatory and James Webb Space Telescope.
