The Gold at Starbow's End
I just binge watched this on Netflix and I knew the premise sounded familiar. I wonder if this series was inspired by the Frederik Pohl short story "The Gold at Starbow's End"? First published in Analog Science Fiction/Science Fact, March 1972. It also was also published in magazine form as "Alpha Aleph" and expanded to a complete novel, Starburst, in 1982. Here's a quick synopsis of the story.
