So, essentially, it’s saying there exist N spatial dimensions (N meaning any number you want). When you throw Time into the mix, you’ve got two ways to think about it:

- You can “reduce” things and think of Time not as one single system, but as multiple, separate timelines.
The author goes with option 2. In this view, it’s not that each spatial dimension gets its own clock; it’s that each possible version of the entire N-dimensional universe runs on its own unique framework of Time.
So instead of:
You’ve got:
These parallel timelines can coexist. When Muad’Dib predicts the future, he’s basically looking across all of them, then locking onto the one timeline he chooses, “freezing” his perception to that single framework and reading the future from there.
