That series strived for realism in that regard, and in using magnetic boots to work in zero gravity; which was admirable. That made the things that were not realistic stand out even more imo. The (unfortunately named) Epstein drive, a drive that consumes very little mass under constant acceleration allows for relativistic speeds in very little time (weeks). Their ships were flying from one side of the solar system to the other in weeks, but they couldn’t make interstellar flights? Also the effects of cosmic rays and hard radiation on reproduction makes the disaffected belter population seem impossible. That’s all fine of course, just inconsistent imo.
Shohreh Aghdashloo performance was a real treat though!
