what is everything, and what is nothing? Professor Jim Al-Khalili explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness. EVERYTHING: what the universe might actually look like and the remarkable stories of the men and women who discovered the truth about the cosmos. NOTHING: science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. The quantum world of the super-small shaped the vast universe we inhabit today, and Jim Al-Khalili can prove it.
