#2042 Yo me ciño a lo que se explica en la wookiepedia:
Hyperspace was a dimension of space-time[1] alternative to that of realspace. It could only be accessed through molecular displacement, which was achieved by breaking the speed of light.[2] It was coterminous with realspace, meaning that each point in realspace was associated with a unique point in hyperspace, and all adjacent points in realspace were adjacent in hyperspace as well. Additionally, every object in realspace (such as stars, planets, and asteroids) had its "shadow" counterpart in hyperspace. Aside from those well-established facts acknowledged by all competent astrophysicists and astrogation experts, other aspects of hyperspace admittedly remained a mystery.[1]
No es lo mismo viajar en la dimensión del hiperespacio, que viajar en a la velocidad de la luz en el espacio real.
