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.
