Is there dark matter at the bottom of a gold mine?

Scientists in the United States are searching for dark matter at the bottom of a South Dakota gold mine as part of a world first experiment.

Earlier this month the world’s most sensitive dark matter detector was lowered into the mine, and it’s now sitting more than a kilometre and a half below the earth’s surface, AP reports.

The instrument was also placed inside a large water tank and it’s hoped both measures will shroud it in enough insulation to isolate dark matter that would be undetectable on the surface.

If the test, known as the Large Underground Xenon experiment, goes to plan the data could be used to answer age-old questions about the universe and its origins.

Scientists at the University of California have been working on the experiment for around five years, and it will take several months before the detector reaches its most sensitive level.
