Cutting-edge astrophysics that builds on Einstein's theories to find the unseen matter that fills the Universe.Dark energy. Dark matter. These strange and invisible substances don't just sound mysterious: their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that...

From the best-selling author of The Seven Daughters of Eve, an eye-opening work no dog lover or ancestry aficionado should be without.How did wolves evolve into dogs? When did this happen, and what role did humans play? Oxford geneticist Bryan Sykes used the full array of modern technology to explore the canine genetic journey when our ancestors first learned to hunt together with wolves. In the process, he discovered that only a handful of genes have crea...

From the big bang to black holes, this fast-paced illustrated tour of time and space for the astro-curious unlocks the science of the stars to reveal fascinating theories, surprising discoveries, and ongoing mysteries in modern astronomy and astrophysics.Before the big bang, time, space, and matter didn't exist. In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theo...

A theoretical astrophysicist explores the ideas that transformed our knowledge of the universe over the past century.The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research—an astrophysicist who literally creates maps of in...

The award-winning science writer "packs a lot of learning into a deceptively light and enjoyable read" exploring the contentious history of the black hole ( New Scientist).For more than half a century, physicists and astronomers engaged in heated dispute over the possibility of black holes in the universe. The strange notion of a space-time abyss from which not even light escapes seemed to confound all logic. Now Marcia Bartusiak, author of Einstein's U...

"Slack engagingly reveals how the Federalist attack on the First Amendment almost brought down the Republic . . . An illuminating book of American history." — Kirkus Reviews , starred reviewIn 1798, with the United States in crisis, President John Adams and the Federalists in control of Congress passed an extreme piece of legislation that made criticism of the government and its leaders a crime punishable by heavy fines an...

“All you have to do is ask ‘why’ and open to any page. Good luck putting it down.” —Alton Brown, host of Good Eats and Iron ChefHave you ever wondered why onions make us cry? Do you believe bananas contain more calories as they ripen and get sweeter? This sequel to the best-selling What Einstein Told His Cook continues Robert L. Wolke’s investigations into the science behind our foods. In response to ongoing questions from readers of his nationally syndic...

In 2000, Martin Bojowald, then a twenty-seven-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity—a cunning combination of Einstein’s theory of gravity with quantum mechanics—to create a simple model of the universe. Loop quantum cosmology was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do—illuminate the very birth of the universe.Ever since, loop quantum...

On July 4, 2012, physicists at the Large Hadron Collider in Geneva madehistory when they discovered an entirely new type of subatomic particle that many scientists believe is the Higgs boson. For forty years, physicists searched for this capstone to the Standard Model of particle physics—the theory that describes both the most elementary components that are known in matter and the forces through which they interact. This particle points to the Higgs field, which provides the key to underst...

The epic, behind-the-scenes story of an astounding gap in our scientific knowledge of the cosmos.In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.Richard Panek tells the dramatic story of how scientists reached this conclus...
