The Yellow Wood is fictional science – not science fiction. In the real world of today’s physics, we have no understanding of what energy is nor do we understand the source of the gravitational force. If there is the tiniest chance that the fictional theories described in this book about energy and gravitation are in fact correct, it would be of incredible importance to our understanding of our world and our universe. The story follows the development of a young physics teacher, Paul, his family and his theories concerning energy, gravitational force and the transmission of light.
