An advanced dark matter detector that hopes to detect an unusual collision between a dark matter particle and a common matter has just been approved in the US, with an opinion to starting the exploration in 2020. Called LUX-ZEPLIN (LZ), the detector will be manufactured in Lead, South Dakota, at the Sanford Underground Research Facility. An old gold mine, the detector will be situated 1, 480 meters (4,850 feet) underground away from any interfering and prepared to detect dark matter. It will be no less than 100 times more sensitive than current detectors, which have until now failed to find any sign for dark matter. The approval came previous month when the US Department of Energy approved the Critical Decision 2 and 3b analyses, which cover the scope, cost, and plan of the ambitious project.

LZ representative and a physics professor at the University of California, Santa Barbara, Harry Nelson said in a statement, "The nature of the dark matter, which includes 85% of all matter in the universe, is one of the most mystifying mysteries in all of the modern science. Just as science has explained the nature of familiar matter, from the periodic table of elements to subatomic particles, counting the just discovered Higgs boson, the LZ project will lead science in testing one of the most eye-catching hypotheses for the nature of the dark matter."
Until now the mysterious matter has stayed elusive. We can see its effects on galaxies, and it is a vital element of our precise models of the universe, but we do not know what it is truly made of. LZ will be searching for a theorized dark matter particle called a weakly interacting massive particle (WIMP). To complete the search, LZ will use a space filled with 10 tons (11 US tons) of filtered liquid xenon. Flashes of light and electrical pulses will indicate particle interactions, and researchers will be expecting some of these hints at dark matter colliding with normal matter.
LZ project manager and a physicist at the Lawrence Berkeley National Laboratory in California, Murdock Gilchriese said in the statement, "Nobody searching for dark matter interactions with the matter has so far persuasively seen anything, anywhere, which marks LZ more important than ever."
Dark matter is supposed to interact only through gravity and not with light, therefore why it received the “dark” prefix. Researchers in many disciplines are testing to limit the properties of dark matter with the help of astronomical observations and particle collider like the Large Hadron Collider (LHC). Positively, LZ will deliver the key information that we are still missing.
