It takes no time at all for a 3D object to travel from its domain into a 2D domain. On the other hand, a 2D object takes infinite time to reach a 3D domain. Inversely, it takes infinite energy for a 3D object to change into a 2D object while a 2D object takes almost zero energy to change into a 3D object.

For example, the entire universe started out as a zero dimension object at the big bang singularity of infinite energy at zero time. Relative to a higher dimension object the big bang took no time at all seen in reverse from 3D to 2D to 1D to 0D. Motion-wise this suggests that, relatively, a higher dimension of space-time has less motion than lower dimension. At the highest dimension of space-time is absolute rest. At the lowest dimension of space-time is absolute motion. Therefore, if the entire universe is evolving into higher and higher dimensions, it should be getting closer and closer to absolute rest. However, where and when seen by a lower dimension observer this universal deceleration appears as universal acceleration.
