New Humans in Space ?

set up for quite primitive gravity environment like in 2001 a Space Odyssey - aliens wouldn't need to use that sort of basic physics to create microgravity environments - hence they can build motherships of any old size and shape that don't have treadmill walkways etc  Who then ? perhaps the millennium human the new corporate model - the place is probably full of macdonalds ...

Thanks to Streetcap1 for finding this
