Imagine a "rope" (for want of a better word) is wrapped all the way around the Earth, to the point that you can hold both ends.
There is no slack on the rope, i.e. it doesn't stretch. It also isn't caught on anything on the Earth's surface and no friction applies to it, if that matters.
If I pull one end in one hand, would the other end move instantaneously? I don't see why it wouldn't but it's hard to imagine it moving straight away when it's wrapped around such a distance.
I'm no physicist so I might not be accounting for something obvious, or it is just that simple. Because of this I also wasn't sure how to tag this. Thanks.
