In a quiet corner of Oxfordshire, particle physicists are dreaming of solving the mysteries of the Universe.
At the heart of the matter is something once described as the tiniest quantity of reality ever imagined by a human being.

The ghostly particles, neutrinos, weigh almost nothing, but they could help explain why the Universe, and everything in it, exists.

If the hopes of scientists are realised, the UK will become home to a neutrino factory.
