Smaller than an atom, and able to race through objects at the speed of light: these mysterious particles are called neutrinos. They could possibly hold the key to the existence of all matter. To observe them, scientists must venture into the eerie silence that reigns only in the most remote places on Earth - or at the bottom of the deepest mines. Using computer animations and access to underground observatories in Canada, Japan, and Antarctica, the documentary follows the interstellar journey of a neutrino crossing our planet from the other side of a black hole.
This fascinating and metaphysical film provides insight into the history of Earth and reveals how the secrets of the universe could be unlocked if we listen to our planet.
