From what I’ve read so far, a space elevator’s counterweight must extend beyond geostationary orbit in order to keep tension on the tether. If you’re higher than GEO, your orbital period will be longer than a day, so how is the counterweight kept stationary when it’s higher than GEO?
In: Physics
The counterweight isn’t in orbit – it is tethered to the Earth.
It would stay there the same way the rock on the end of a string stays extended when you whirl it around your head
