The Cube tether physics

The mathematics has become excruciating I'll have you know, and in fact alot of the calculations are showing some very non-intuitive results (all with good reasons after I really think hard about it).

However I am bent on success, since a real Skyhook, even functioning at a hundredth of its capacity, would represent a 30- to 90- fold increase in launch capacity over the space shuttle.

As for the complex and non-intuitive results, the greatest challenge is presenting the information in a functional manner. This is truely tough stuff.
