Dark Matter Hunters Construct a New Weapon - Detector

That dark matter has never been found is no deterrent to the physicists who are looking for it.

“Even if we don’t know what dark matter is, we know how it must act,” said Eduardo Abancens, a physicist at Spain’s University of Zaragoza and designer of a prototype dark matter detector.

According to physicists, only around five percent of what makes up the universe can presently be detected. The existence of dark matter is inferred from the behavior of faraway galaxies, which move in ways that can only be explained by a gravitational pull caused by more mass than can be seen. They estimate dark matter represents around 20 percent of the universe, with the other 75 percent made up of dark energy, a repulsive force that is causing the universe to expand at an ever-quickening pace.
