While I have no doubt it would require an unreasonable amount of material and resources, so not doable... I wonder.... would a space-elevator made out of modern materials, but shapped like a pyramid with a broad base, be able to be made tall enough to extend into space. I figure if the base is wide enough and the materials at least as strong as solid rock, it should be possible... but without running the numbers I dunno... I do know there is a limit on the maximum size of a mountain so .... i dunno.
