Anchor a tube on earth and slope it all the way into space

  1. Aug 11, 2009 #1
    All right, I know I'll make an azz of myself with all the big brains around but I have to know. (My physics knowledge is at a high school level so please forgive my ignorance)

    I we were to anchor a tube on earth and slope it all the way into space, would anything happen? Has there been experiments? Theories?

    Just my stoner brain I guess :)

    Thanks guys!

    The only thing that would happen is that you'd have a very long tube sticking out of the atmosphere. There would be no flow of air through the tube for the same reson that the atmosphere doesn't blow away into space: gravity. The pressure difference between the top and the bottom is exactly offset by the force of of gravity so the net flow is zero.

    If you make the tube exactly the right length, you'll get a space elevator:


    but without the elevator :rofl:

    Thanks a lot neg. Makes a lot of sense (even to me) :tongue2:

    Great link, ideasr. Go nanotubes...want to see that elevator built in my lifetime.
