LUX-ZEPLIN

Researchers at the Sanford Underground Research Facility in Lead say they’ve taken a huge step forward in the quest to confirm the existence of dark matter. Late last month, they finished assembling the key piece of the LUX-ZEPLIN experiment’s xenon detector. 

Proving the existence of dark matter requires enough precision to catch two flashes of light that would be undetectable to human eyes. Scientists believe those flashes happen if a dark matter particle collides with a xenon atom.
