It turns out black holes shrink as the Universe expands. A new model has combined a rotating black hole with cosmic expansion: the ergosphere and event horizon decrease, while dark energy shows no reaction to the hole's spin.
🎯 The shrinking event horizon works like a patch on an air mattress: when the fabric stretches, the patch tightens but the thread stays intact.
🎬 Sci-fi writers imagine black holes as portals, but in this work, they are merely obedient objects, shrinking in the swelling cosmos.
