"So no information is traveling faster than the speed of light"---this is the key distinction. I feel like we are on the verge of no longer saying the speed of light, but the speed of causality or information seems more relavant.

I've seen many depictions of black holes looking like a funnel, a heavy object on a trapoline or studied using water to create a vortex. All the depictions make it seem as if the event horizon is on a singular plane. How accurate could this be for actual black holes? I picture in my head, a central point or singularly being in one static position while the space around it is warped from every possible direction creating infinite vortices all being "stretched" (down?) Towards the singularity.

I guess my question is: Do we need to think in higher dimensions to be able to understand black holes and is it feasible that humans will ever one day be capable of imagining and comprehending anything but the 3 spacial dimensions we've been adapted to believe?
