A Wrinkle in Time (And Space)

The fifth dimension. A topic of hot debate, especially between astrophysicists and particle physicists. Mathematically and abstractly, the fifth dimension is structurally legitimate. The fifth dimension is a dimension that supposedly exists at a right angle to time. If one were to draw a space-time diagram (please read Stephen Hawking's books for reference for now about space-time diagrams; I'll explain them later), then add an extra axis at a right angle to time, then it would look as though once an object reaches a certain point in time, it could suddenly change to a different position in space.
Is instantaneous travel throughout the universe possible? Maybe.
