How did it all begin? Where is it all going? A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. His theory changed the way we think about space and time, revealed how our universe has been expanding from a hot dense state called the big bang and predicted black holes. WHERE THE UNIVERSE CAME FROM is a 13.8-billiion-year journey through the cosmos. Discover how Einstein's work explains why the cosmos is the way it is, why 95% of the universe is missing, how physicists go to extraordinary lengths to unlock gravity's secrets and how black holes could hold the key to a theory of everything.
