Between the Strokes of Night (1985)Charles Sheffield
In this chapter, a group at Gulf City receives a long-delayed communication from a colony on Kallen's World, revealing challenges in identifying the origin of stellar changes affecting their galaxy. The colony reports difficulties in locating the first star to have changed spectral type, which is crucial to understanding the stellarforming phenomenon, and passes the responsibility back to the Gulf City team. The meeting concludes with a discussion on the limitations of current data and the need for patience and passive observation to solve the mystery.
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.
