I've read a bunch on space elevators and from what everyone is saying, it would be required that the elevator is in geosynchronous orbit. From my understanding, that is so that it would stay fixed in one position over the earth.
Also, from my understanding a space elevator would be some sort of cable that runs up into space and so people would essentially ride that cable up. Now that would also explain why it would need to be in geosynchronous orbit, since the cable would then otherwise wrap itself around the earth.
That got me thinking though, what if you were to build a super-structure from the ground up. Something similar to the image below. If you were able to create a structure strong enough to withstand the all of the elemental forces in the upper atmosphere:
- Would it be possible to have the structure sticking out into space, but not in geosynchronous orbit?
- What would be the challenges in creating a structure like this?
- Could something like this change the earths rotational period?
