Why is our universe three dimensional? Cosmic knots could untangle the mystery
Next time you’re untangling your earbuds in frustration, here’s an idea to help put it in perspective: knots may have played a crucial part in kickstarting our universe, and without them we wouldn’t live in three dimensions.

There are already answers to that in string theory and in cdt theory.

With so many elementary particles in close proximity, they would have created a whole mess of flux tubes. Most of these tubes would have quickly been destroyed though, since matter and antimatter annihilate each other when they meet, taking the flux tubes with them.
>but there are times when flux tubes can survive longer than the particles that they link. If those particles move in just the right way, they can twist their flux tubes into knots, which are stable enough to exist on their own. And if several of these flux tubes intertwine, they can form an even more stable network of knots, which would have quickly filled the early universe.
That seems novel.
