Researchers pioneer a new way of searching for dark matter
The existence of dark matter is a long-standing puzzle in our universe. Dark matter makes up about a quarter of our universe, yet it does not interact significantly with ordinary matter.

In a new study, scientists report results from the PandaX-4T experiment, setting stringent limits on dark matter–nucleon interactions using low-energy data and the Migdal effect, ruling out significant parameter space for ...
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional ...
