A Centuries-Old Experiment Could Help Find Dark Matter

Physicists are reviving the Cavendish experiment with a modern twist to search for hypothetical milicharged particles that could make up part of dark matter.

Using oscillating electric fields inside a Faraday cage, the proposed method could detect tiny violations of Gauss’s law with remarkable sensitivity—potentially opening a new way to investigate the hidden matter of the universe.
