Having read the book Friday by Robert Heinlein many years ago, I became aware of the concept of the space elevator/ space tethers. While fascinating in concept, our current technology negates the reality of this idea, however the physics involved are sound and it is a real possibility.
In the novel Friday, there were several colonies on multiple tethered space stations. To be honest, I don't remember mention of a gravitational effect on those stations. Was there gravity present from either mechanical means i.e. Star Trek-style "gravity generators" or from the Centrifugal action of the tether itself, or was it never actually stated, just implied?
