As long as they knew the velocity of travel, they could determine their position using the three-dimensional model of the star system they had previously observed.
However, Lynn shook his head, not approving of this method. If conditions were normal, it might indeed be useful, but not now, as the Curvature Engine created a ring of distorted spacetime around the outside of the spaceship.
The space ahead was continuously stretched inward, and because distances were shortened, from a lower-dimensional perspective, both the light carrying information and the spaceship seemed to surpass the speed of light.
Of course, the real situation was that the distance between them was greatly shortened by the distortion of space and time.
So, the appearance of a light screen wasn't because their speed truly exceeded the speed of light by several multiples, but because the light itself was also accelerated when crossing that area of space...
