can we space elevator? should we space elevator?

From acollierastro.

I am so sorry but I don’t understand why anyone wants a space elevator.

Coffee and the problem Episode 1: The science fiction writer R. A. Heinlen describes a skyhook satellite that consists of a long rope placed in orbit at the equators, aligned along a radius from the center of the earth, and moving so that the rope appears suspended in space above a fixed point on the equator. The bottom of the rope hangs free just above the surface of the earth (radius R). Assuming that the rope has uniform mass per unit length (and that the rope is strong enough to resist breaking!), find the length of the rope.
