Main Question or Discussion Point
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!
Hi lovegood! Welcome to PF!how do i use space-time diagram to explain that the displacement is zero?
unless its near a naked singularity and in a closed time loop :tongue2: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?
