- A woman who is lying in a coma in a hospital and later tells what at that time was discussed in the hall of the hospital, far from the department where she lay... - A man who recognizes people who previously were only in his surroundings while he lay in coma... - A woman who for surgery is cooled down to a level where her brain no longer functions, reports on that operation from personal observation Just three of the millions of near-death experiences (NDE's) that people have experienced in a life-threatening situation. How can that be? What is that, an NDE? And what do the deeper phases mean in which people meet deceased relatives and friends in a different world? Is there a relation with religion? Dr. Wiebe Oost is a physicist who became fascinated by the impossible observations these people did. He set out to try to place this puzzling phenomenon within the framework of modern science, but without repeating the mistake of earlier attempts to find an explanation which ignored the majority of the phenomena. In "On Heaven’s Edge" you will find a report of his quest and his conclusions. They shed a new light on matters like the human mind and the reality of an afterlife
