"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)....

The universe is rapidly expanding. Of that much scientists are certain. But how fast? And with what implications regarding the fate of the universe? Ellen Jackson and Nic Bishop follow Dr. Alex Fillippenko and his High-Z Supernova Search Team to Mauna Kea volcano in Hawaii, where they will study space phenomena and look for supernovae, dying stars that explode with the power of billions of hydrogen bombs. Dr. Fillippenko looks for black holes--areas...
