University of Calgary researchers are a part of a group who just got one step closer to solving a mystery of the universe. Dr. Timothy Friesen, Ph.D., an associate professor of Physics and Astronomy in the Faculty of Science, and his team led a new measurement comparing the spectrum of hydrogen to its antimatter counterpart—antihydrogen.

The results of this new measurement are published in the journal Nature.

“Fairly core in our theoretical models is the symmetry between matter and antimatter, and if that symmetry is broken there would be a huge impact on how we construct those theories and how we think about our absolute laws in physics,” says Friesen.
