"In 1916, Einstein became the first to predict the existence of gravitational waves: sounds without a material medium generated by the unfathomably energy-producing collision of black holes. Now, Janna Levin, herself an astrophysicist, recounts the story of the search, over the last fifty years, for these elusive waves--a quest that has culminated in the creation of the most expensive project ever funded by the National Science Foundation ($1 billion-plus)....

"From your own backyard, exploring soil and sand, to great, big machines that dig, this board book explores everything that digs with fun photos and colorful design."--Publisher's website.

The Chicken Squad uncovers mysterious remains while digging a meteor/storm shelter, and they stop work to investigate just as a big storm is approaching.

"On Friday, Llama will destroy the world."--Page [4] of cover.

Scientists are all aboard an Earth discovery vessel on a fruitless search for life in space when they encounter a lost spaceship perched on the event horizon of the universe's most powerful phenomenon, a black hole.

"The astonishing science of black holes and their role in understanding the history and future of our universe. Black holes are the most extreme objects in the universe, and yet they are ubiquitous. Every massive star leaves behind a black hole when it dies, and every galaxy harbors a supermassive black hole at its center. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Which...

Sam and Dave are on a mission. A mission to find something spectacular. So they dig a hole. And they keep digging. And they find ... nothing. Yet the day turns out to be pretty spectacular after all.

"Zia imagines what might happen if the hole in her pocket became big enough to fall right through."--

According to astrophysicist Tyson, director of New York City's Hayden Planetarium, size does matter when it comes to black holes, although the chances of your surviving the encounter aren't good in any case. Tyson takes readers on an exciting journey from Earth's hot springs, where extremophiles flourish in hellish conditions, to the frozen, desolate stretches of the Oort Cloud and the universe's farthest reaches, in both space and time. Tyson doesn't...

"In a riveting course designed to give non-scientists the matchless experience of scientific discovery and deep understanding, The Evidence for Modern Physics: How We Know What We Know takes you through the most remarkable insights of contemporary physics, showing why physicists believe what they do."--The Great Courses.
