Science is not about a collection of facts, but rather it is a way of analyzing what we observe. The concept is, if you have a good theory it will predict things, then you can go out, do experiments, and see if you are right. Of course, in general it is not so easy to form a theory without resorting to nature, which means that most theories largely explain what is known. Nevertheless, the objective is to make a limited number of predictions of what we do not know. Someone then goes out and carries out the experiments, tests or whatever and if the theory is correct, the observations are just what the theory predicted. That is great news for the theoretician.
That is all very well, but what happens when there is a phenomenon that cannot be the subject of an experiment. In a previous post (http://wp.me/p2IwTC-6q ) I remarked that my Guidance Wave interpretation of quantum mechanics permitted, but by no means required, life after death. This cannot be experimented on and reported, however there are a number of reports of people who claim to have “almost died” or momentarily died and who have been revived and then given quite strange and explicit stories. What can science say about them?
One comes from a book I was given to read. Written by a pastor Todd Burpo, it tells of what his son, who was just short of four years old at the time, reported after he had nearly died in hospital. The son made several statements, all of which entailed an “out of body experience” and most involved a short visit to heaven to sit on Jesus’ lap. However, two of the descriptions were of more interest to me, because they described how the “out of body” boy saw his parents, each in a different room, and described what they did. In principle, there is no way he could have this information. The story also has a very frustrating element. The boy described the marks on Jesus’ hands, from the crucifixion. The pastor took that as clear evidence, because how would the boy know where the marks were? The most obvious reply is, he lived in a religious house and there probably were images around. Further, and this is the frustrating part, the standard Roman crucifixion did not have nails through the hands, so the boy was wrong, right? The problem is, Jesus did not have a standard crucifixion. What usually happened was that the victim was left on the cross until the flesh had more or less rotted away or had been picked by the crows, then the residue was disposed of, but not given a burial. To cut the body down and give it for burial was never done, except this time. Accordingly, if it were non-standard, it may have been the soldiers put the nails where it would be easier to get them out later. In short the killer evidence essentially ends up as useless. There is then the added complication that if true, Jesus may have given the image the pastor wanted.
The second is also interesting. Harvard neurosurgeon Dr Eben Alexander was in a coma for several days caused by severe bacterial meningitis. During his coma, he too had a vivid journey, first into other rooms, from which he described people’s actions that he had no possibility of knowing about through his physical body, and then into what he knew to be the afterlife. Now he had previously been a skeptic about this, and considered such accounts to be hallucinations, but in his own case his neocortex was non-functional during his coma, and furthermore, he gives nine different scientific reasons why what he experienced cannot be due to such hallucinogens or imagination. Since I am not an expert in brain function, I cannot comment usefully on his analysis. On one hand he is a prominent neurosurgeon, and should be an expert on brain function, so his analysis should be taken seriously, nevertheless, as Richard Feynman remarked about science, the easiest person to fool is yourself.
Perhaps the most spectacular accounts have been presented by Elisabeth Kübler-Ross, MD, a psychiatrist. She had noted that if children have this experience, they always see their mother and father if the parent is dead, but never if they are still alive. Christian children often see Jesus; Jewish ones never do. One particularly unusual account came from a woman who described what people were doing trying to resuscitate her after an accident. She claimed to have had this out of body experience and had watched everything. What is unusual about this is the woman was blind; the out of body “her” could see everything, but when she was resuscitated, she reverted to being blind. Another unusual report was from someone who met one of his parents in this “afterlife”, who confirmed being dead. This parent had died only one hour previously, five hundred miles or so away.
At this point we should look at the structure of a scientific proposition. There are two conditional forms for a statement that apply to a proposition under a given set of conditions:
(a) If the hypothesis is correct, then we shall get a certain set of observations.
(b) If and only if the hypothesis is correct, then we shall get a certain set of observations.
The difference lies here. In (a) there may be a multiplicity of different hypotheses that could lead to the observation, such as a hallucination, or a memory dump. This would apply to observations that the person could have recalled or imagined. In (b) there is only one explanation possible, therefore the hypothesis must be correct. Obviously, it is difficult to assert there is only one possible explanation, nevertheless, seeing something in another room when nearly dead seems to only being explained by part of the person (the soul, say) travelling out of the body into the other room.
So, where does this leave us? Essentially, in the position that there can be no proof until you die. Before that it is all a matter of faith. Nevertheless, as I argued, my guidance wave interpretation of quantum mechanics at least makes this possible within the realms of physics, but it does not require it. Accordingly, you either believe or you do not. The one clear fact though, is that if you do believe, it will almost certainly make dying easier, and that in itself is no bad thing.
