> Einstein was inspired because as a patent clerk he worked across from the railway station and was very aware of time, time standards, physical trains.

[citation needed] I guess he was more inspired by the Michelson experiment and the Lorentz transformations.

Gravity works exactly like here (But you can jump higher). Time works exactly like here too (The length of the day and the year are different, it will be a problem to choose a good calendar, but it's already a mess here. Anyway, it's not a scientific or technological problem, people just don't want to change the calendar they are use to.)

Perhaps they will find a few new interesting cases for climate science an geology???

They would spend all their time struggling to stay alive; no real science would ever get done. Look at the space station today. They're in a low earth orbit, completely dependent on resupply and accomplish very little other than siphon funding from unmanned exploration that actually leads to amazing breakthroughs because, "humans in space!"
