The Ghost Particle
The cosmos has a secret ingredient: a swarm of invisible particles that fills every cubic inch of space. Trillions of them zip through our bodies but we don't even notice. Yet without these ghostly, mysterious particles known as neutrinos, the sun wouldn't shine and the elements that make up our world wouldn't exist. The story of the 70-year struggle to understand these particles is a tale of atom spies, secret laboratories and mind-boggling disappearances.
