What is dark matter? Even for astrophysicists, it’s a question that remains unanswered.
These invisible particles make up most of the matter in the universe and about a quarter of the universe as a whole. They are thought to be the cosmic glue that binds the universe together, but we still don’t know what kind of particle they are. Finding the answer to that question could provide us with an unprecedented understanding of the past, present and future of our known universe.
New research from astrophysicists at Northeastern University provides a potential new way of answering this age-old question.
“Everything in the universe is a particle and a wave and a field, so the baseline [assumption] is dark matter must be a particle,” says Jacqueline McCleary, an assistant professor of physics and author on this recent paper. “The question is what kind of a particle, as a particle is very vague.”
