Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to find meaning in the face of this vast expanse. Greene takes us on a journey from the big bang to the end of time, exploring how lasting structures formed, how life and mind emerged, and how we grapple with our existence through narrative, myth, religion, creative expression, science, the quest for truth, and a deep longing for the eternal.

In June of 1916, Albert Einstein published his ambitious paper proposing the existence of gravitational waves. In 2016, Einstein's 100-year-old theory was proven correct when scientists detected ripples in the fabric of space. Einstein and Relativity: A Conversation by Paul Rudd and Brian Greene celebrates this achievement, with Greene and Rudd sitting down to talk about string theory, relativity, and the discovery of gravitational waves.

Based on the NPR series of the same name, This I Believe features 80 Americans—from the famous to the unknown—completing the thought that begins with the book's title. The pieces that make up the program compel listeners to re-think not only what and how they have arrived at their own personal beliefs, but also the extent to which they share them with others.

In a rare blend of scientific insight and writing as elegant as the theories it explains, Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.

Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past?
