A Quantum Crystal That Will Search for Dark Matter
Scientists at the US National Institute of Standards and Technology (NIST) have created a quantum crystal that could potentially be used to detect dark matter using quantum entanglement and “time reversal”.
Capturing a bonafide axion could be the key to unlocking one of the biggest unsolved mysteries in science: the nature of dark matter. Scientists know that dark matter exists because we can see its immense gravitational effects on the “normal” baryonic matter that makes up our bodies, planets, and stars. But because it doesn’t emit any conventional signals, dark matter has proved to be difficult to observe and explain, even though it is five times as abundant as normal matter.
