Exploring the Possibility of a Space Elevator: Nanotubes and the Future of Space Travel

The video discusses the concept of a space elevator, a cost-effective method to send payloads into space. Dr. Bradley Edwards proposes using a ribbon made of carbon nanotubes, which are stronger than steel, to support the elevator. The cable would be attached to a platform on the equator and could carry up to 13 tons. Edwards plans to launch sections of the cable into space using rockets, aiming for a more reliable system than traditional boosters. The development of the necessary carbon nanotube strength is expected to take about two more years.
