Ultracold state of matter reveals potential dark matter candidate's fuzziness.

Scientists have used an ultracold state of matter called Bose-Einstein condensate (BEC) to mimic the behavior of "fuzzy" dark matter, which is believed to be made up of tiny particles with wave-like behavior. The team found that BECs resembled the physical state at the cores of fuzzy dark matter "halos" and that there were specific similarities with BECs. This achievement is promising for future attempts to create laboratory settings that replicate aspects of matter distribution in the universe on a smaller scale.
