Using a specially designed 3D printed vacuum system, scientists have developed a way to "trap" dark matter with the aim of detecting domain walls. This will be a significant step forwards in unraveling some of the mysteries of the universe.

Scientists from the University of Nottingham's' School of Physics have created a 3D printed vacuum system that they will use in a new experiment to reduce the density of gas, and then add in ultra-cold lithium atoms to try to detect dark walls. The research has been published in Physical Review D.

Professor Clare Burrage from the School of Physics is one of the lead authors on the study and explains, "Ordinary matter that the world is made from is only a tiny fraction of the contents of the universe, around 5%, the rest is either dark matter or dark energy—we can see their effects on how the universe behaves but we don't know what they are. One way people try to measure dark matter is to introduce a particle called a scalar field."
