For General Readers
For thousands of years, the soul has been considered as a supernatural entity ouside the realm of science. This book suggests that the soul could be a physical entity known as the gravitational geon which is likely to be the origin of consciousness. A living brain may create the gravitational geon that constitutes the conscious part of the mind whereas the gravitational geon (soul) created by a dying brain exhibits out-of-body experience. The size of a soul geon is estimated to be about 5 meters in radius.
