We know dark matter exists thanks to observations of large-scale structure, galactic dynamics, and precision observations of the CMB. All of these observations suggest a gravitational interaction. A key open question concerns the particle nature of dark matter, and its interactions with ordinary matter.
The LZ Experiment aims to answer this question, offering new sensitivity to possible dark matter - nucleon scattering. Check out some fun Q&A with a handful of my LZ colleagues in the video on the left.
Even if LZ detects dark matter, it will not answer all the questions we have. We are also working on instrumentation R&D towards future experiments which will offer additional sensitivity to interactions of dark matter with ordinary matter.
