Researchers have created the first diamond nanothreads -- which are basically like carbon nanotubes, but stronger and stiffer. Mathematically, these diamond nanothreads are possibly the strongest and stiffest material that can be constructed in the known universe. As interest in space elevators and other international megaprojects swell, these diamond nanothreads might be exactly what we need to get crazy seemingly impossible constructions off the whiteboard and into reality.
