Position of a ship in a new dimension

[lovegood]

i need some help here, say if there's a ship, no matter how it steers, it will always end up at the starting point, becauses it is in a new dimension, but how do i go about explaining it? thanks!

 

[lovegood]

how do i use space-time diagram to explain that the displacement is zero?

What do you MEAN by "in a new dimension"?

 

[lovegood]

as in fourth dimension?

 

[HallsofIvy]

Then how does a spaceship "move into the fourth dimension"?

Hi lovegood! Welcome to PF!

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.

Or am I misunderstanding you?

unless its near a naked singularity and in a closed time loop

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.
