LONDON (Reuters) -- British scientists equipped with state-of-the-art detectors deep underground in northern England have begun a search for one of the most tantalizing secrets of the universe -- Dark Matter.
"If we are successful in our quest then we are looking at a place in the history books," Neil Spooner of Sheffield University said Tuesday. "This will be one of the great discoveries of our time."
Scientists around the world are racing to be the first to discover the truth about Dark Matter, which cannot be seen because it does not emit light. They believe it makes up the vast majority of the universe.
Scientists say stars account for less than 1 percent of the mass of the universe, with gas clouds and other objects accounting for close to another 5 percent.
