Cosmic Inflation Explained

Cosmic inflation proposes that, in the first moments after the Big Bang, the universe expanded at an extremely rapid, accelerating pace for a brief instant before easing into the slower expansion we observe today. This book introduces the idea to young readers through clear explanations of harder topics, including dark energy, dark matter, and the cosmic microwave background, supported by vivid illustrations. Together these ideas show how researchers studying inflation have changed what we know about the universe's origin, its development over time, and its possible future.

The title is built around the scientific method. It draws on data gathering, analysis, and theories supported by evidence, in line with the emphasis on those skills in the Next Generation Science Standards. Sidebars look more closely at current, related subjects, and a Further Reading section suggests additional sources for students who want to keep exploring.
