It's a metaphor
You know how when you throw a rope into a box, when you take it out it’s all tangled? Here’s a weird fact: nobody really understands why.
It’s hard to imagine it happening any other way, but really, when you think about it, why would a rope get tangled so badly just because you stopped looking at it? Shouldn’t it just pretty much sit there and do nothing, like other objects do? Where does this chaos even come from?
Strange but true: if you put rope in a box, but leave one end of the rope hanging out, it won’t tangle. You can pull on the free end of the rope and get the whole thing out of the box without a single knot. But as soon as both ends of the rope are in the box, all bets are off. It will get tangled and knotted for sure.
