We humans know that we're going to die. We hope that we will have some form of afterlife. But we know that our bodies decay. Therefore in order to have an afterlife there must be some part of us that survives death. We have come to believe in the concept of the soul.
This book describes a possible scientific explanation for the soul and describes the ongoing tests by NASA and others that may lead to proof of some of the elements of the scientific speculations described in this book.
