New Proposal to Search for Dark Matter - Universe Today
Dark matter is a mystery. Astronomers know it's there because they can measure the effect of its gravity on stars and galaxies, but they can't see it. One theory about the nature of dark matter is that it's composed of theoretical subatomic particles called Weakly Interacting Massive Particles (WIMPS). A team from Italy believed they detected these WIMPs back in 1998, but other scientists were skeptical. A researcher from the University of Utah has proposed that the Italians search for different streams of particles coming from different galaxies to validate their original experiment.
