Can scientists make a space elevator?
"The question Artsutanov asked himself had the childlike brilliance of true genius. A merely clever man could never have thought of it -- or would have dismissed it instantly as absurd. If the laws of celestial mechanics make it possible for an object to stay fixed in the sky, might it not be possible to lower a cable down to the surface, and so to establish an elevator system linking earth to space?" -- Arthur C. Clarke, 1979, "The Fountains of Paradise"
(CNN) -- It sounds like science fiction. And it was.
Now, 30 years after "2001" author Arthur C. Clarke wrote about an elevator that rises into outer space, serious research is happening all over the world in an effort to make the far-fetched-sounding idea a reality.
