Cosmic Queries: StarTalk's Guide to Who We Are, How We Got Here, and Where We're Going

Neil deGrasse Tyson and James Trefil organize this volume around ten fundamental questions concerning the origin and fate of the universe. The text moves from the Big Bang and the initial expansion of space-time to the formation of stars, planets, and the eventual cooling of the cosmos. It details physical laws like the constant speed of light and the behavior of subatomic particles, while also addressing contemporary mysteries such as dark matter, dark energy, and the possibility of a multiverse. The authors integrate historical scientific breakthroughs with current data from observatories to explain how life emerged on Earth and where humans fit into the chemical timeline of the galaxy.

This book serves curious readers who want a clear overview of astrophysics without overly technical jargon. It appeals to those who enjoy the conversational style of the StarTalk podcast and want a visual guide to complex phenomena like black holes or the cosmic microwave background. Readers finish the book with a firmer grasp of the scales of time and space, gaining a practical understanding of the evidence used to determine the age of the solar system and the ultimate trajectory of our universe.
