Scientists are still trying to discover the origins of the universe. The latest attempt will be soon in the Black Hills of South Dakota. The old Homestake Gold Mine has been turned into a lab to do experiments in dark matter. They will be using a dark matter detector. Why? "Regular matter—people and planets, for
example—make up about 4 percent of the total mass-energy of the
universe. Scientists estimate that dark matter makes up about 25
percent." If they can detect the dark matter, "it could explain why the universe isn't made
up equally of matter and antimatter. That, in turn, could explain how
the world as we know it came to be."
"Dark matter is too sensitive to detect in
normal laboratories, but one so far underground would help shield it
from pesky cosmic radiation. Also, the LUX detector is submerged in
water, further insulating it."
