Lucy Kirkwood's new play is about families and particle physics. It premieres at the National Theatre, London, in July 2017. Alice is a scientist. She lives in Geneva. As the Large Hadron particle collider starts up in 2008, she is on the brink of the most exciting work of her life, searching for the Higgs Boson. Jenny is her sister. She lives in Luton. She spends a lot of time Googling. When tragedy throws them together, the collision threatens them all with chaos.
