黑洞事件视界是宇宙学耦合的

Black hole event horizons are cosmologically coupled

Valerio Faraoni, Massimiliano Rinaldi

AI总结:

证明静态球对称黑洞视界无法嵌入含时几何,指出因宇宙膨胀黑洞必然与宇宙学耦合,这为超大质量黑洞增长机制提供了依据并对暗能量难题具启示意义。

摘要:

证明了严格静态且球对称的黑洞事件视界无法嵌入含时几何。若强行嵌入,会在预期视界处产生裸零奇点。因此,由于宇宙正在膨胀,黑洞必然与宇宙学膨胀耦合,这被提出作为星系中超大质量黑洞的增长机制,并对暗能量难题具有启示。

英文摘要:

It is shown that an exactly static and spherically symmetric black hole event horizon cannot be embedded in a time-dependent geometry. Forcing it to do so results in a naked null singularity at the would-be horizon. Therefore, since the universe is expanding, black holes must couple to the cosmological expansion, which was suggested as the growth mechanism for supermassive black holes in galaxies, with implications for the dark energy puzzle.
