A Space Elevator is a proposed structure designed to transport materials and people from the Earth's surface to space. It would consist of a long cable anchored to the Earth and extending into space, allowing vehicles to ascend and descend along the cable, significantly reducing the cost of reaching orbit.
The concept of a space elevator has been popularized by science fiction and theoretical physics. It relies on advanced materials, such as carbon nanotubes, to withstand the immense tension and gravitational forces. If realized, a space elevator could revolutionize access to space and facilitate further exploration of our solar system.
