In the real world a sufficiently long lever would break.

https://en.wikipedia.org/wiki/Space_elevator

talks about a sufficiently long cable, which - if anchored to the 
earth's surface and extended above sychronous orbit height - would build 
a stair way to the stars, or at least to synchronous orbit.

Any real material cable would break under the tension. Carbon nanotubes 
are almost strong enough.
