Physicists from Harvard University explore the possibility that dark matter، or a small amount of it، may have an electric charge، as the Technical Times said.
If true، dark matter would be able to interact with ordinary matter through an electromagnetic force، allowing scientists to dig deeper into this elusive material that makes up 25 percent of the universe.
It would also shed some light on a more recently uncovered mystery about the beginnings of the universe.
Researchers led by Julian Muñoz، theoretical cosmologist and postdoctoral fellow at Harvard's Department of Physics، are taking inspiration from research concluded in February.
Working out of the Murchison Radio-astronomy Observatory in Western Australia، the Experiment to Detect the Global Epoch of Reionization Signature (EDGES) were able to detect radio signals from 180 million years ago، at which point the first stars were born to form the early universe.
The EDGES team also created a profile of the young universe's radio waves، which helped Muñoz and his team come up with their findings.
Most scientists believe that when the first generation of stars shone their light، they emitted ultraviolet rays that pulled the electrons from atoms of hydrogen that were floating around in the space between the stars.
