Hartle believes that the general theory of relativity should be a part of the university science curriculum. He hopes to remove a gap in the knowledge of undergraduate students, so they can better understand how scientific theory and observation are connected. 

Hartle illustrates his book by discussing the exciting phenomena that have been discovered by those who have dedicated their lives to learning about gravity. For example, he uses the Global Positioning System satellites, black holes, X-ray sources, pulsars, quasars, gravitational waves, the Big Bang (a cosmological event), and large-scale structures in the universe to illustrate his point about how general relativity explains an array of everyday and exotic phenomena.

Understanding Gravity

In 'Gravity', James B. Hartle takes us on a journey to understand the fundamental concept of gravity. He explains it in a way that's easy to grasp, even if you're not a physicist. You'll find yourself seeing the world in a whole new light after reading this book.

The Role of Einstein

Hartle digs into Einstein's theory of relativity, showing us how it revolutionized our understanding of gravity. He makes it clear that without Einstein, our current knowledge of the universe would be vastly different.

The Universe and Beyond

The book isn't just about gravity on Earth. Hartle explores the role of gravity in the wider universe, from black holes to the Big Bang. If you've ever wondered about the cosmos, this book will give you a lot to think about.

The Impact of Gravity

Gravity isn't just a scientific concept. It impacts our daily lives in ways we often don't realize. Hartle helps us see how gravity influences everything from the tides to the way we age.

The Future of Gravity Research

Hartle doesn't just look at what we already know about gravity. He also looks ahead to the future of gravity research, giving us a glimpse into the exciting discoveries that could be just around the corner.
