In an English newspaper today, there is a report of some research done by scientists that proves that a Kindle (or any other electronic book) actually weighs more when loaded with a few virtual manuscripts to read than it does when totally empty. Not much (it has to be calculated, it is so minute a difference), but a calculable amount nevertheless. I love it when the world of science and the 'paranormal' move closer toward each other - as they inexorably must - and I love the way that the more esoteric the science, the more it seems to prove the existence of God - or at least God's idea of God, as revealed to us in revelations (with a small 'R').
This modern day intellectual experiment is on an exact parallel to the ones carried out in the days before the Age of Reason, when clerics would spend many hours discussing how many angels could fit on a pin-head. Although we laughed about such a notion in a later, secular society, it seems to me that these Theologians may have been employing the exact same science as is now used by all the physicists since Einstein, and nobody laughs at them these days.
For obvious reasons, it is very difficult to carry out experiments on people at the point of their death, but it has - I believe - been done once or twice in the past.
I remember hearing that one or more people have, in the past, agreed to cooperate by allowing themselves to be placed on a highly sensitive set of scales when they are about to die. They were weighed in the seconds before their expiry, then immediately afterwards, and it was found that the corporeal frame was measurably lighter after they had breathed their last.
It may be a massive jump in supposition (a quantum leap is a very small event indeed) to deduce from this that humans do indeed have 'souls', and that these souls leave the body considerably lighter when they vacate, but - as I have said before - I am prepared to believe in anything. Life is so much more exciting when you can.
The few corpses of people I have known very well that I have looked at, actually seem dramatically smaller when the life has left them, and I am not talking about the way that the drop in blood-pressure deflates the flesh of the deceased in death. Even the bones seem smaller - the size of the head, etc. so that the empty person looks like a miniature version of their live self.
Another experiment done some years ago discovered that if you sit quietly and imagine yourself to be in a gym for an hour a day, you actually start to develop muscle growth as if you had been weight-training.
Similarly, the more you exercise your brain, the larger it gets - even though it is not a muscle and there is always plenty of cellular room for terra-bytes of information which will never be assimilated in a single lifetime.
Of course, it is also possible to restrict the growth of your brain by consuming a bottle of wine every night. You wouldn't want to end up looking like a Mekon, would you?
