Hi lovegood! Welcome to PF! :smile:

If your fourth dimension is time, then the ship can't return to its starting-point … because, on the space-time diagram, the ship must always be going up. :smile:

Or am I misunderstanding you? :confused:

I am not sure if this answers what you are asking but perhaps your dimension is a point, no matter how you move you are still at the beginning. Or perhaps you are referring to a closed dimension, like the surface of a ball. No matter how you move would can (not will) end up back at the beginning.
