Black holes are indeed cool, but they are also complicated and misunderstood. Sean Carroll just published a book that describes diving into a black hole (at the end of a lot of discussion of physics), or if you prefer short story format I think there’s a pretty accurate Greg Egan story about the process, though I don’t remember if that goes into the whole “time gets rotated to become a spacelike dimension” thing.
