Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe. Now, Tyson invites us to go behind the scenes of his public fame by unveiling his candid correspondence with people across the globe who have sought him out in search of answers. In this hand-picked collection of 100 letters, Tyson draws upon cosmic perspectives to address a vast array of questions about science, faith, philosophy, life, and of course, Pluto.

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: Observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria.

In this illuminating audiobook, Tyson and coauthor James Trefil, a renowned physicist and science popularizer, take on the big questions that humanity has been posing for millennia - How did life begin? What is our place in the universe? Are we alone? - and provide answers based on the most current data, observations, and theories.

Black holes are some of the most mystifying and mysterious parts of our galaxy. How big can a black hole get? Do black holes ever die? What does it sound like when black holes smash into each other? Learn the answers to all of these questions and more in this fascinating look into the phenomena scientists are learning more about every day.

Speed limits. Internet speeds. The speed of Earth. There are so many aspects of human life that are ruled by speed, even if we don’t realize it everyday. In this best of Seeker collection, you’ll learn how we decide speed limits, how fast a thought travels, how much acceleration the human body can take, and the simple discovery that let us fly faster than the speed of sound.
