Why did I love this book?
If you’ve ever wondered how the universe could have originated from a speck and expanded in a big bang, or why scientists came to believe such a thing, this book explains it all in an accessible, gripping story. Overbye, who is a science writer for the New York Times, paints a sweeping history of big bang cosmology through the colorful characters who put it together in the second half of the 20th century. The story revolves around astronomer Allan Sandage, who was a student of the famed Edwin Hubble. After Hubble discovered that the stars were arranged in galaxies that were speeding away from each other, he died, leaving Sandage to finish his quest to understand the implications of this expansion, measure the age of the universe, and determine whether the cosmos is eternally spreading out into an ever more sparse and lonely place.
