The nature of the excess and whether it could be originating from dark matter has been debated for over a decade." Credit: NASA Goddard/A. Mellinger (Central Michigan Univ.) and T.

Dark Matter's Quantum Nature Leaves No Trace in Detectors

A graph from the PRL publication showing that the quantum nature of axion dark matter (shown on the left), an ultralight wave-based dark-matter candidate, vanishes when viewed by a modern detector (shown on the right), whether or not researchers are using advanced quantum technologies to detect them.
