Further signs of dark matter have been observed at a subterranean laboratory in northern Minnesota.
The Super Cryogenic Dark Matter Search ( or SuperCDMS ) is located underground and uses a highly chilled environment to help scientists pick up signs of potential dark matter particle collisions. For this to work, germanium and silicon are reduced to freezing temperatures near absolute zero ( 273.15 degrees Celsius ) and the collisions are detected using super-sensitive instrumentation.
Scientists at the project have revealed that they've picked up three events thought to indicate particle reactions that could be evidence of dark matter. While not enough to prove dark matter exists, the results are particularly tantalizing and will be cross-examined for further clues to indicate what caused them.
"Hints of dark matter, the mysterious stuff that makes up perhaps 85 percent of the matter in the universe, may have been observed by scientists."
