They are all around us in every nook and cranny. Trillions upon trillions inside and out of every planet, star, galaxy and the space in between. Billions pass through you every single second, night and day. But despite the phenomenal numbers it was not until 1953 that conclusive evidence of the existence of the most abundant thing in nature was discovered: the neutrino.

Since then scientists have devoted their lives to chasing these ghosts of nature. Despite its meagre size the tiny neutrino has had a profound effect upon our Universe and may hold  the answer to one of the greatest questions of all time: the Creation of the Universe.

Dr Ben Still is a particle physicist. He works as part of an international collaboration of about 500 scientists and engineers on the Tokai to Kamioka (T2K) experiment in Japan. The T2K experiment aims to use the world's most intense beam of neutrinos, one of the least understood of the fundamental particles, fired from the East coast of Japan to the Super-Kamiokande particle detector 295km to the West. By investigating the changes in the their properties as the neutrinos travel between the two sites physicists can get closer to understanding these Universe-creating particles.
