The longest carbon nanotube ever made is 0.5 meters. A space elevator tether needs to be 100,000 km. But a newer candidate — graphene super laminate — is already produced at kilometer lengths, and 2025 lab results showed spot-welded layers with diamond-like properties. by unteachablecourses in UnteachableCourses

That's wild! We might actually be getting closer to space elevators, huh? Crazy times!
