For the last decade, the science community has debated back and forth over whether or not the conceptual "space elevator" could actually be constructed. The elevator would carry cargo and possibly even life forms (though warm or cold blooded I am unsure) from a base on Earth to a suspended space station caught within the earth's gravity. The cord's tether design on this thing would theoretically be made out of carbon nanotube filaments. Apparently the measured strength of microscopic carbon nanotubes appears great enough to make it theoretically possible.
Don't believe me STILL- there was actually a contest between nano tech gurus to see who could build the strongest thether!
