Between the Strokes of Night (1985)Charles Sheffield
The Argo crew experiences an unprecedented acceleration to 99.9997% of light speed, drastically reducing their subjective travel time to Gulf City, but raising tensions about alien intentions and leadership. Upon arrival, they find Gulf City abandoned by humans, with only robots present, and discover that due to relativistic effects and differing time frames between S-space and N-space, over twenty thousand years have passed for planetary colonies, leading to a profound cultural and technological disconnect. The crew confronts the reality that Gulf City is no longer the central hub of the spiral arm, and that their assumptions about time and progress were fundamentally flawed.
