If a blackhole is huge within rather than tiny (only its compressed expression appearing tiny to outsiders, so a gravity well of increasing depth, and thus increasing space), couldn't it have layers of event horizons, separated by vast amounts of space where nature operates as normal, perhaps even locally and perceptually expansive despite ultimately still being drawn closer into the next inner event horizon and further away from the previous outer event horizon. With the possibility the next inner event horizon is wider/larger/deeper/further/vast than its prior event horizon.

  • $\begingroup$ A Kerr black hole has multiple horizons, but (probably) not like how you're describing. On a related note, I think you'd enjoy Lee Smolin's fecund universes hypothesis. $\endgroup$

  • $\begingroup$ What does "blackhole is huge within rather than tiny" mean? This makes no sense. The event horizons of some SMBHs would comfortably fit Jupiter's orbit around the Sun. Perhaps you might start by reading how an event horizon is defined (eg on Wikipedia), and then edit your post if there's still something worth asking. For further guidance, see How to Ask and take the Tour. :-) $\endgroup$ 10 hours ago
