Engineering studies on space elevators confirm that a tether extending beyond geosynchronous orbit can be used by climbers to deliver payloads into space and interplanetary trajectories.
The claim is a specific, empirical aerospace engineering concept. Retrieved papers [1] and [5] discuss space elevator mechanics, tethers extending beyond geosynchronous orbit, and their role in transporting payloads into space and facilitating interplanetary travel, directly supporting the physical feasibility of launching payloads into solar orbits via space elevators. Other papers are off-topic or tangential.
