A scientific and globetrotting exploration of the physics experiments changing the ways we understand our universe.

Why is the universe expanding? What is the nature of dark matter? Do other universes exist? In this timely and original book, science writer Anil Ananthaswamy embarks on a global journey to some of the world's most inhospitable and dramatic research sites to witness first-hand the audacious physics experiments conducted to answer profound questions about the nature of the universe.

From the Atacama Desert in the Chilean Andes to the European Southern Observatory's Very Large Telescope on Mount Paranal to deep inside an abandoned iron mine in Minnesota and to the East Antarctic Ice Sheet, Ananthaswamy weaves together stories about the people and places at the heart of this cosmological research.
