Warum Zeit und Raum in einem Schwarzen Loch vertauschen

I hate this fruity analogy, because time and space don’t really swap in any real sense, only in an abstract mathematic sense that has no real bearing on a layman’s perception. Passing the event horizon simply seals your fate, that’s all. Time does not reverse direction or loop backward—it still progresses forward in the sense that cause precedes effect, and an observer’s proper time (their own clock) ticks onward in one direction. This is just a very colourful way of saying your future is sealed to one fate.
