You may be interested to hear that the people of our visiting races each take rest time from their work here once or twice per Earth year.
All of them use the opportunity of our widest holiday downtime to take turns visiting their homes and families.
This is because even with advanced technologies of dimensional travel, it still takes a long time to cross space between our worlds.
So to carry out their specialty work here, most of the crews of our visiting races must live here in large crafts parked outside of our atmosphere.
Considering each of our visiting races from near and far, travel to Earth takes them an average of two weeks.
All advanced races in all the Universes visit their neighboring worlds.
And each of our visiting races, most from our arm Orion of our Milky Way Galaxy, also visits some of our other visiting races' worlds.
As neighbors, we all share the same little tiny part of space.
