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

Over the past few decades, a handful of scientists have been racing to explain a disturbing aspect of our universe: only four percent of it consists of the matter that makes up you, me, our books, and every star and planet.

The rest is completely unknown.

Richard Panek tells the dramatic story of the quest to find this “dark” matter and an even more bizarre substance called “dark energy”.

This is perhaps the greatest mystery in all of science, and solving it will bring fame, funding, and certainly a Nobel Prize.
