The title space does not allow a whole lot in the way of explanation:
coming out of the labs now are carbon nanotubes that are not yet totally up to full potential strength but they are making enough to wind up 18 miles a day of the stuff now in one length, making the space elevator concept a whole lot closer! :

If you look at the comments, at the end of them I made one about a concern of mine with the counterweight of the theoretical elevator, there is the station at geosync orbit but needing a counterweight a hundred thousand miles beyond that where the pull on the tether will be AWAY from the earth. I worry about how the two would be kept in a more or less straight line, how would they do that since an object orbiting a hundred thousand miles up has a natural orbital period a lot longer than one in 24 hour (by definition, geosync) orbit.
