skyhooks and cranes

Submitted by ccrichar on Sun, 03/01/2009 - 5:05pm.
Skyhooks and Cranes are metaphors that do not appeal to me in context to the course.  Skyhooks cannot be foundational and Cranes are foundational.  Skyhooks need to involve the galaxies in order to be foundational and Cranes just need the earth to stand upon.  I do not understand skyhooks as a foundation.  A foundation needs something to stand upon and skyhooks has none other than the galaxies.  And then which galaxy does it stand upon?
