Scientists are about to launch an ambitious search for a “dark force” of nature which, if found, would open the door to a realm of the universe that lies hidden from view.
The hunt will seek evidence for a new fundamental force that forms a bridge between the ordinary matter of the world around us and the invisible “dark sector” that is said to make up the vast majority of the cosmos.
The chances of success may be slim, but should such a force be found it would rank among the most dramatic discoveries in the history of physics. The best theory of reality that physicists have explains only 4% of the observable universe. The rest is a mystery made up of dark matter, the strange material that lurks around galaxies, and the even more baffling dark energy, a substance called upon to explain the ever-accelerating expansion of the universe.
“At the moment, we don’t know what more than 90% of the universe is made of,” said Mauro Raggi, a researcher at the Sapienza University of Rome. “If we find this force it will completely change the paradigm we have now. It would open up a new world and help us to understand the particles and forces that compose the dark sector.”
