Whats dark matter.

A wispy dark sector particle could interact with ordinary matter by emitting a dark photon that morphs into an ordinary photon. But that low-energy photon would barely nudge a nucleus. In the right semiconductor, however, the same photon could excite an electron and enable it to flow through the material.The “discovery” of dark matter.
