Ah thanks, I was a dingus and looked up the diameter instead of the circumference. Still doesn’t really matter where you build it. No matter what it’s fucking up a a good portion of the equator if it falls.

It still can’t really fall. It’d be moving incredibly fast sideways. Fast enough to miss the Earth for a while. Geo stationary orbit is the point where orbital speed matches Earth’s rotational speed, so if it’s anchored at the ground, then it’s at orbital speed if at GEO. The higher the orbit, the slower the orbital speed. So using a higher orbit to maintain tension means it’d be traveling beyond escape velocity, held down by the cable. A break would release the mass into the solar system

I think that depends on how big the tether is tbh. It has to be usable as an elevator so it can’t just be a thin cable. And your scenario is assuming that it would be cut down near the base, if it’s damaged anywhere higher up anything below the cut will fall down to earth.

Yeah that’s kinda what I was envisioning, maybe half the tether zingin off into space when the other half fell into the pacific or desert, but even half is gonna be like 20,000km I guess.
Also wasn’t there a scenario like this in one of the Mars Trilogy books?

Not certain about the mars trilogy but there is a collapsing space elevator in the foundation series (at least on the show, haven’t read the books yet.)
