2001: A Space Odyssey Part 6, Chapter 41

Grand Central

• Lots of description about extra-stellar weirdness outside the pod. In the film, this is where you get twenty minutes or so of trippy psychedelic lights. Can't do that in a book, so it's just Arthur C. telling you that things look somewhat weird.
• It's not as effective, really.
• There's some faster than light travel going on which messes with Bowman's clock (space and time are all smooshed together. Einstein said so).
• Bowman's watch actually stops altogether, but Bowman's still moving.
• He's above a planet; he realizes it's some sort of cosmic switch station.
• You pick a Star Gate, and it sends you somewhere in the universe.
• Like a railroad switch engine yard, but with more stars.
