Parapsychology
Main article: Parapsychology See also: Near-death studies and Near death experienceA study conducted in 1901 by physician Duncan MacDougall sought to measure the weight lost by a human when the soul "departed the body" upon death. MacDougall weighed dying patients in an attempt to prove that the soul was material, tangible and thus measurable. Although MacDougall's results varied considerably from "21 grams", for some people this figure has become synonymous with the measure of a soul's mass. The title of the 2003 movie 21 Grams is a reference to MacDougall's findings. His results have never been reproduced, and are generally regarded either as meaningless or considered to have had little if any scientific merit.
The Society for Psychical Research was founded in 1882 with the express intention of investigating phenomena relating to Spiritualism and the afterlife. Its members continue to conduct scientific research on the paranormal to this day. Some of the earliest attempts to apply scientific methods to the study of phenomena relating to an afterlife were conducted by this organization. Its earliest members included noted scientists like William Crookes, and philosophers such as Henry Sidgwick and William James.
J. B. Rhine, who was critical in the early foundations of parapsychology as a laboratory science, was committed to finding scientific evidence for the spiritual existence of humans. Scientists who have worked in this area include Raymond Moody, Susan Blackmore, Charles Tart, William James, Ian Stevenson, Michael Persinger and Pim van Lommel among others.
After 25 years of parapsychological research, Susan Blackmore came to the conclusion that there is no empirical evidence for an afterlife. David Fontana however on the subject of parapsychology has said that "the evidence for survival is so strong that anyone who cares to study it is likely to end up convinced". He further says that the reason there is no complete conclusive repeatable evidence is because that if the afterlife was so demonstrable then it would become "another chapter in a school textbook" and that "the whole process of questioning, probing, studying, observing, meditating and of wanting so desperately and enduringly to know, is part of the development of mind itself".
Some, such as Francis Crick in 1994, have attempted a "scientific search for the soul". Frank Tipler has argued that physics can explain immortality, though such arguments are not falsifiable and thus do not qualify, in Karl Popper's views, as science.
In 2008, Penny Sartori, an intensive care nurse from Swansea, published a book about near death experiences following 10 years of research. Sartori says that people who went through out-of-body experiences felt as if they floated above themselves and were able to accurately recount what had happened in the room even though their bodily eyes were closed.
Investigation of the afterlife also includes the study of (among others) cases of haunting, apparitions of the deceased (including, in some cases, information conveyed by those same apparitions), instrumental trans-communication (recording of electronic voice phenomena on tape), and mediumship.
