该研究解决了膨胀宇宙中黑洞视界演化的问题，证明黑洞表观视界倾向于共动，证实宇宙耦合的必要性，为黑洞早期增长提供新可能。
AI 中文摘要
此前研究表明，在随时间变化的背景中，静态黑洞的事件视界无法存在，否则会成为裸奇点。鉴于此，留下的问题是：黑洞视界在膨胀的宇宙中如何演化？本文给出该谜题的解决方案，全面证明黑洞的表观视界倾向于成为共动的，从而证实宇宙耦合的必要性，并为黑洞的早期增长提出引人关注的可能性。
英文摘要
It has been shown that static black hole event horizons cannot exist in time-dependent backgrounds without becoming naked singularities. In light of this, we are left with the question ``how does a black hole horizon evolve in an expanding universe?'' Here we offer a solution to this puzzle by showing in full generality that regular black hole apparent horizons tend to become comoving, thus confirming the necessity of a cosmological coupling and raising intriguing possibilities for the early growth of black holes.
