This week's Question: Penn State researchers recently developed ultra-thin, super-strong nanothreads made from diamonds. The nanothreads could ultimately be used to construct a "space elevator" to take people to orbit. A Japanese company, Obayashi, similarly sees the feasibility of such an elevator and envisions a space station tethered to the equator by a 96,000-km cable made of carbon nanotechnology. In theory, robotics cars with magnetic motors would quickly take people and cargo to the station. What do you think? Will cosmic elevators take us to space?
