Sure knots, like this trefoil, may be shaped from vortices in a quantum fluid

By manipulating a quantum fluid, researchers might type liquid knots that by no means unravel. These might assist us make clear odd quantum objects from the daybreak of the universe.
When tiny whirlpools referred to as vortices type in a fluid, they’ll make loops that may then be knotted like a loop of string. However whereas a string can type knots that received’t unravel with out the assistance of scissors, knotted vortices in a fluid break away extra simply. They will explode right into a diffuse swarm of…
