"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)....

At the heart of our galaxy lies a monster so deadly it can bend space, throwing vast jets of radiation millions of light years out into the cosmos. Its kind were the very first inhabitants of the universe, the black holes. Join Professors Brian Cox and Jeff Forshaw in exploring our universe's most mysterious inhabitants, how they are formed, why they are essential components of every galaxy, including our own, and what secrets they still hold, waiting...

Follows Dr. Alex Fillippenko and his High-Z Supernova Search Team as they use the Keck telescope in Hawaii to look for supernovae, find black holes, and study the effects of dark energy.

"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....
