Africa-Press – Cape verde. <\/strong><\/span>Scientists believe that roughly 85 percent of the Universe is made of dark matter – a certain type of material that cannot directly be observed since it does not emit light or energy.<\/p>\n

An old gold mine and a vat containing liquid xenon are the key elements of an ongoing hunt for the elusive dark matter that is believed to make up about 85 percent of all matter in the Universe.<\/p>\n

This hypothetical form of matter doesn\u2019t emit, absorb or scatter light, while existing almost everywhere in our Universe, making it undetectable in astronomical observations. In the hopes of solving this fundamental mystery, a team of researchers picked an old gold mine in Lead, South Dakota, US, burrowing down underground to a depth of nearly a mile, or 1.6 kilometers, to block out all background noise.<\/p>\n

The experiment spearheaded by Lawrence Berkeley National Lab (Berkeley Lab) with contribution from physicists at the University of Massachusetts Amherst and involving an international team comprising around 250 engineers and scientists is calculating on catching the undetectable dark matter as it interacts with other particles.<\/p>\n

The crucial element of the Sanford Underground Research Facility is liquid xenon, sitting inside two titanium tanks, fitted with detectors able to zoom in on miniscule flashes of energy potentially coming from a particle of dark matter colliding with a xenon atom. The titanium is designed to keep the liquid xenon cold and also to maintain background radiation down to a minimum.<\/p>\n

According to the plan for the experiment, the mysterious dark matter might come from the theoretical Weakly Interacting Massive Particles (WIMPs). The WIMPs, if they exist, while interacting with gravity, could be expected to collide with particles of visible matter on rare occasions. Early results are expected sometime in 2023, with observations scheduled to continue for up to five years.<\/p>\n
