"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)....

When a little boy finds a hole in his garden he fills it up with the things that he loves hoping for a tree to grow. As the hole gets bigger, there is no tree to be seen. Read through to see what finally happens to the hole.

Find out what black holes are, what causes them, and how scientists discovered them.

"On December 26, 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves generated from merging black holes for the first time in human history. But why is this significant? Through an engaging, easily accessible approach, the origins, dynamics, and ultimate fate of black holes are thoroughly unraveled so that students without a scientific background can grasp complex physics theories. This text supports the...

"Hill and Hole were best friends. Hill likes being a hill, and Hole likes being a hole, but sometimes they wonder what it would be like to swap places. Maybe Mole and Wind can help?"-- Two friends, a hill and a hole, long to be more like one another.

A desperate game of survival unfolds after 13 year old John traps his family in a hole in the ground in this unsettling psychological thriller. Based on the short story by Nicolás Giacobone *El Pozo*

"From the acclaimed author of Black Hole Blues and Other Songs from Outer Space--an authoritative, wholly accessible, fascinating guide to the most challenging phenomena of contemporary science, which is now the anchor of our understanding of the cosmos. Throughout her career, astrophysicist Janna Levin has focused, alongside her research, on making the science she studies not just accessible, but, perhaps more important, intriguing to the nonscientist....

"Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole's core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics....

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.
