Strong Hints Of Dark Matter Detected By Space Station

Dark matter is a type of matter hypothesized to account for a large part of the total mass in the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level. Instead, its existence and properties are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe.

Physicists announced last Wednesday that they have discovered the most convincing evidence yet of the existence of dark matter. Members of an international team gathered at Nasa in Washington and Cern in Switzerland to report their findings, which come from a $2bn particle detector mounted to the International Space Station.
