Today there are three known materials strong enough for a #SpaceElevator: carbon nanotubes, hexagonal boron nitride, and single crystal graphene. Single crystal #graphene is currently the most promising. https://www.isec.org/space-elevator-tether-materials
In graphene, the #carbon forms a sheet of interlocked atoms as hexagons one carbon atom ⚛️ thick https://en.wikipedia.org/wiki/Graphene
T1200-grade fibre has a tensile strength 💪 10 times greater than ordinary steel, yet it is less than one-tenth of a human hair in diameter. Using 120,000 carbon-fibre filaments twisted together, the carbon-fibre rope has a diameter of under 2mm when taut. It is strong enough to tow a coach 🚍 loaded with 54 adults https://www.scmp.com/news/china/science/article/3346398/china-beats-us-japan-carbon-fibre-arms-race-create-worlds-first-t1200-factory
Building a space elevator would take great mastery of engineering and materials science.
Would it make a big difference if the anchor station on Earth could move?
Like if we built a railroad around the equator and let the base of the elevator rotate around the Earth, what speed would the train have to be going to make the actual elevator cable portion of the system a lot easier?
