But few of us understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Where are we going? Award-winning astrophysicist and Professor of Physics at Princeton University, Jo Dunkley traces the evolution of the Universe from the Big Bang fourteen billion years ago, past the birth of the Sun and our planets, to today and beyond. She explains cutting-edge debates about such perplexing phenomena as the accelerating expansion of the universe and the possibility that our universe is only one of many.
