It is physically possible to build a ladder all the way to the Moon. A structure made out of close-to-ideal carbon nanotubes would have sufficient strength.
It would just require an unbelievable complex carbon nanotube 'weaving' system that can somehow operate and move directly between the Earth and Moon.
Which is quite an interesting parallel to the complexity of the human brain when I think about the analogy.
- HPsquared 3y agoHow would it behave with the relative movement and rotation of the moon/earth? Would it maintain a stable position? I imagine it would wrap around the earth if it was fixed to the surface. But if it's free floating, wouldn't it want to fall one way or the other? Or spin somehow? EDIT: this would be a good one for Randall Munroe's "What If" EDIT EDIT: of course: https://what-if.xkcd.com/157/ https://what-if.xkcd.com/157/
- cyanydeez 3y agothere's no material stuff enough. it'd basically go logarithmic, eventually parallel to rotation.
