The precise distance from the Atlantic station to the one in space must be 22,23 million meters above Earth. The geosynchronous orbit starts there, and the four outward forces are stronger than the downward forces. To create a space elevator, the construction would start from the bottom and move up. The main problem is the weight of the line, which could disrupt the orbit and the conveyor. To balance the station in space, the line would need to be tapered. Steel is one of the most robust materials on Earth, but it is cumbersome and heavy. Lighter materials like kevlar, carbon, and titanium could be used to increase the strength of the cable. Carbon nanotubes, a unique material with a strength of 130 Gap Pascals, could be used, but the cost of building the cable is too high.
