Scientists at the University of Nottingham’s School of Physics have embarked on an ambitious mission to trap dark matter using a specially designed 3D printed vacuum system. By detecting domain walls, they hope to unlock some of the mysteries surrounding the universe. This groundbreaking research has been published in Physical Review D and promises to shed light on the elusive dark matter and dark energy that dominate the cosmos.

The Theory Behind the Experiment

The researchers based their experiment on the concept that light scalar fields undergo density-driven phase transitions, leading to the formation of domain walls. These defects, known as dark walls, are crucial in unveiling the existence of scalar fields, which constitute a significant portion of the universe’s composition. By lowering the density and observing defects in the scalar fields, the team aims to prove the existence of dark walls, providing invaluable insights into the nature of dark matter.

The team led by Professor Clare Burrage and Associate Professor Lucia Hackermueller meticulously designed the 3D printed vessels used in the experiment. These vessels were constructed based on theoretical calculations of dark walls to create the ideal shape for trapping dark matter. By cooling lithium atoms to near absolute zero (-273°C) using laser photons, the researchers were able to manipulate quantum properties, facilitating precise analysis and detection of dark walls.

To detect dark walls, the team exposed a cold atom cloud to the trapped dark matter. The deflection of the atom cloud served as evidence of the presence of dark walls. By firing laser photons at the atoms, the researchers reduced the energy within the atoms, akin to slowing down an elephant with snowballs. This meticulous experimental process required three years to develop and is poised to yield groundbreaking results within a year.

Whether the experiment confirms the existence of dark walls or not, it represents a significant advancement in our understanding of dark energy and dark matter. By conducting controlled laboratory experiments, scientists can directly measure phenomena that are otherwise unobservable, offering key insights into the fundamental forces shaping the universe. The research underscores the importance of innovative approaches in unraveling the enigmatic mysteries of the cosmos.

The quest to trap dark matter using a 3D printed vacuum system represents a pioneering endeavor in the field of astrophysics. By harnessing the power of technology and innovative experimental design, scientists continue to push the boundaries of our understanding of the universe. The discovery of dark walls could fundamentally alter our perception of the cosmos and pave the way for new insights into the elusive nature of dark matter and dark energy.
