如果宇宙学暗物质有一个由小的原始黑洞（BH）组成的成分，它们可能会对第一批恒星的物理学和随后大质量黑洞的形成产生重大影响。原始黑洞会被压缩到这些恒星中，然后通过动力摩擦下沉到恒星中心，产生一个更大的黑洞，可能会很快吞噬整个星星。如果这些原始黑洞的质量超过1022 g，那么第一批恒星可能只会存活很短的时间，对宇宙的形成不会有太大的贡献。
If the cosmological dark matter has a component made of small primordial black holes (BHs), they may have a significant impact on the physics of the first stars and on the subsequent formation of massive BHs. Primordial BHs would be adiabatically contracted into these stars and then would sink to the stellar centre by dynamical friction, creating a larger BH which may quickly swallow the whole star. If these primordial BHs are heavier than ∼10 22 g, the first stars would likely live only for a very short time and would not contribute much to the
