Summary
How do you detect a particle that emits no light - in other words, something invisible? This is the intriguing challenge faced by scientists hunting for 'dark matter'. In our series finale, we talk to Elizabeth Bloomfield from Oxford's Department of Physics about dark matter, how we know it exists, and why her research is taking her deep beneath a mountain in Italy in the quest to find it.
