Materials For Space Elevators - From Carbon Nanotubes To Graphene And Beyond...

Such a fleeting and ethereal thing, won't even survive being tightly held in one's grasp. And yet, while easily smothered, it never truly dies. It only becomes more real in its absence, and somehow, it always finds its way back to you again.

After all the worldly wealth and power will have crumbled to nothing, all the flames burnt out and all waters dried away, sit down on the last piece of rock, open your palm and close your eyes. It will be there, waiting for you.
