Underground lab searching for dark matter
July 5th, 2009
Located two kilometres deep into the Vale Inco Creighton Mine, near Sudbury, Ont, the SNOLAB International Underground Science Facility (www.snolab.ca) is an ultra-clean environment, shielded from most of the effects of cosmic rays. It’s the deepest lab of its kind. From inside its isolated confines, scientists search for dark matter particles left over from the Big Bang and try to pinpoint a rare radioactive process called neutrino-less double beta decay which could spell out how matter evolved in the early universe. The dark matter the SNOLAB site hunts for is thought to make up about 25% of the mass in the universe. The rest is 5% ordinary matter — what you and I are made up of — with the remaining of the universe comprised of “Dark Energy.” Debate rages about what Dark Matter particles are, as scientists around the world try to search for it.
