The gravity here was about 15% higher than their home world and a politician somewhere had decided this was within acceptable limits.
Within a few generations the people here would start to look heavier and more muscled than the people of their home planet. At first a few jokes would be made about this, but a few new colonists might still slip on board the Empire shuttles sent a few times a year to pick up mined minerals and produce.
Then the people here would start to look so different that no one wanted to come here and no one wanted them to come home. Even the constant chatter over the Empire's network would reduce. Of course the shuttles would continue to take away good and bring whatever had been bought by the colonists, but no one would want to be seen dead on New Algaria.
