"A near-death experience happens when quantum substances which form the soul leave the nervous system and enter the universe at large, according to a remarkable theory proposed by two eminent scientists.

According to this idea, consciousness is a program for a quantum computer in the brain which can persist in the universe even after death, explaining the perceptions of those who have near-death experiences."

"It is based on a quantum theory of consciousness he and British physicist Sir Roger Penrose have developed which holds that the essence of our soul is contained inside structures called microtubules within brain cells."
