Black holes are common objects in the universe. Each galaxy contains large numbers-perhaps millions-of stellar-mass black holes, each the remnant of a massive star. In addition, nearly every galaxy contains a supermassive black hole at its center, with a mass ranging from millions to billions of solar masses. This review discusses the demographics of black holes, the ways in which they interact with their environment, factors that may regulate their formation and growth, and progress toward determining whether these objects really warp spacetime as predicted by the general theory of relativity.
黑洞是宇宙中常见的天体。每个星系都包含大量——也许有数百万个——恒星质量的黑洞，每个黑洞都是一颗大质量恒星的残骸。此外，几乎每个星系的中心都有一个超大质量黑洞，其质量从数百万到数十亿个太阳质量不等。这篇综述讨论了黑洞的分布情况、它们与周围环境相互作用的方式、可能调节其形成和生长的因素，以及在确定这些天体是否真的如广义相对论所预测的那样扭曲时空方面取得的进展。
