Dark matter makes up roughly a quarter of the universe, with normal matter only making up five per cent and the remainder being dark energy. Image credit: NASA, ESA, CFHT, CXO, M.J. Jee (University of California, Davis), and A. Mahdavi (San Francisco State University)
A new proposal has been made describing the nature of the ever-so-elusive dark matter. In this new research, astronomers suggest that some particles of dark matter, which constitutes the majority of all matter in the universe, contain an extremely tiny electrical charge that interacts with normal matter through electromagnetic force.
“You’ve heard of electric cars and e-books, but now we are talking about electric dark matter,” says Julian Munoz of Harvard University in Cambridge, Massachusetts, United States. “However, this electric charge is on the very smallest of scales.”
This work by Munoz and his collaborator Avi Loeb of the Harvard-Smithsonian Centre for Astrophysics (CfA) in Cambridge, Massachusetts, United States, coincides with the recently announced results by the Experiment to Detect the Global EoR (Epoch of Reionisation) Signature (EDGES) collaboration. In February 2018, it was announced that scientists detected a radio signature from the first generation of stars that formed only 180 million years after the Big ...
