The 4% Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality

Exploring “one of the most important stories in the history of science” (Washington Post), Panek nimbly outlines recent findings in physics, astronomy, and cosmology and evaluates rival theories in clear, comprehensible language. He also dives into the bureaucratic morass and professional enmities of contemporary research, examining how these discoveries were made as well as who made them. While some critics appreciated this behind-the-scenes human drama as a tool for understanding the full story, others believed that Panek’s alternating focus on the scientists themselves detracted from the actual science. However, even readers who prefer their science straight up will find much to admire in this accessible and fascinating survey of one of the most exciting—and maddening—fields of study.
