so if a object on earth was tied to it it would be pulled into space? would it have to go escape velocity or it would slowly be pulled into space?

Shaky is a structural engineer; now he's actually in his element.

So...no spooling?

If you had a rope that stretched from the Earth 1000 miles into geostationary orbit, then the speed at one end of the rope would not be the same as the other end (at the equator, the Earth rotates at 1038 mph. 1000 miles up, the other end of the rope would be traveling ~1298 mph). This would cause the rope to want to tumble, but one end is attached to a building. If the rope and building was strong enough to withstand these forces, then the rope would fall to the Earth. I doubt there will be any spooling, but I don't know for sure.

It would stay straight and spin with the earth if it had the correct counter weight on the other end, this is what some are actually working on builing a space elevator🙂

I'm surprised no one caught my mistake: a wire "only" 1000, or even 10,000 miles long, could not spool around the Earth's 25,000-mile circumference.

So what if astronauts going to the moon drew out a wire 200,000 miles long? Anchored to Mt. Everest, would that spool as Earth rotated?

Wasn't sure if you meant spooling around the Earth or around the building.

if it did spool around the earth would it stay in orbit or fall to earth?

it would fall to earth

EDIT: again, showing my lack of physics knowledge, aren't all orbits either anterograde or retrograde? like, isn't the idea of something just "orbiting" another body sort of untrue? Like, the moon is eventually getting farther from earth, and our satelites are eventually coming down...

I believe that is the case, since otherwise would mean (I think) some sort of unchanging perpetual motion. All we see in our fleetingly brief lives are snapshots of cosmic activity.

Also: in falling to Earth, it would be interesting to speculate what type of havoc this unbreakable wire would wreak as it settled (tightened?) into place. Would it, eg, slice through landscapes? the crust?
