Migration between star systems happened very slowly.
Traveling between stars required enormous amounts of energy and careful planning. Even with advanced technology, journeys often took many years or even centuries. Because of this, migrations were never rushed.
Before a new system was chosen for settlement, scientists and engineers studied it for a long time. They observed the star's stability, the number of planets in orbit, the presence of water or useful minerals, and the level of radiation in the region.
Only when a system showed long-term stability did civilizations begin building habitats there.
Most of the time, settlers did not land directly on planets. Instead, they built large artificial habitats in orbit. These habitats could be carefully controlled environments where temperature, gravity, air, and water were managed by stable systems.
This approach allowed people to live safely even in systems where planets were not suitable for life.
