Also, Oldcron drive...

I believe they are going FTL in realspace. I believe they just turn off their most/all of their mass and inertia and do the inertialess drive thing. They have to slow down to turn though. I suppose they could be using hyperdrive/hyperspace. *shrugs*. It seemed like star trek style warp drive, hah..


Anyway, it's notable that in this setting, you don't get exponential technical increases; you get lots of civilizations (including minor civilizations that mostly do their own thing) hitting massive walls of technological understanding, and tech being stagnant for a very, very long time...
