Space Elevators

A space elevator is a theoretical structure that extends from Earth's surface into space, allowing objects to be transported without rockets. Imagine a tall, strong cable anchored at the equator, with a counterweight beyond geostationary orbit. Gravity pulls the cable downward, while centrifugal force from Earth's rotation pulls it outward, creating tension that keeps it taut. Vehicles called climbers can ascend or descend along the cable, carrying payloads efficiently and potentially reducing launch costs. Though technologically challenging, space elevators could revolutionize access to space by providing continuous, energy-efficient transit.
