What is the weight of the human soul ?

[!gad]The idea of a material soul is not new. The Greek philosopher, Heraclitus, who lived in the sixth century BC, thought that the soul was composed of an unusually fine or rare kind of matter, such as air or fire. However, if it was material it had to have some weight. Barbara Brennan, former NASA engineer and now world-renowned energy healer, observes that ‘aura’ appears to have weight. Robert Monroe also believes that the ‘Second Body’ has weight, although much less than the carbon-based body. (The terms ‘aura’, ‘astral body’ and the ‘Second Body’ refer to what is generally described as the ‘subtle body’ in the metaphysical literature. The subtle body has often been loosely identified as the ‘soul’.)

If the soul has weight, it means it has mass and is subject to Earth’s gravitational force. This has motivated various researchers, including Noetic Science, to undertake experiments to weigh the soul. In 1907, Dr. Duncan McDougall weighed six patients, while they were in the process of dying from tuberculosis. When death was imminent, the entire bed of the patient was quickly placed on a highly sensitive industrial sized scale. In each case, when the patient expired, he noticed an extremely small sudden change in the weight of the deceased which could not be accounted for by other means. The missing mass, which this weight loss represented, was used to support his hypothesis that the body had a soul which had mass. On the death of the visible body, the soul departed, and so did this mass. The weight of the soul, based on the average loss of mass in six patients, was measured by McDougall to be 21 grams. A paper summarising his findings appeared in the journal American Medicine in 1907. One critic quickly pointed out that the sphincter and pelvic floor muscles relax at death, and that the loss was perhaps due to ejected urine and/or faeces. McDougall rebutted that if this were the case, the weight would remain upon the bed and, therefore, upon the scale.

Someone else suggested that the dying patients’ final exhalation might have contributed to the drop in weight. To disprove this, McDougall climbed into the bed and exhaled “as forcibly as possible” while his assistant watched the scale. No change was observed. Another critic reasoned that body weight was being continually lost as water escapes into the air through What is the Weight of the Human Soul? An Estimate Based on Dark Matter Statistics 70 NEW DAWN ¦ Special Issue No. 15 www.newdawnmagazine.com the evaporation of perspiration and the water vapour that goes out with the breath. McDougall claimed to have accounted for this also. His first patient, he wrote, lost water weight at the rate of an ounce per hour, far too slowly to explain the sudden threequarter- ounce (about 21 grams) drop precisely at the time of death. In the 1920s, Dutch physicists Drs Malta and Zaalberg Van Zelst claimed that the (physical-etheric) subtle body is capable of expanding by 1.26mm and contracting by 8mm. According to them, it was composed of “extremely small and widely separated” atoms and had a density of 176.5 times lighter than air and weighed, on average, 69.5 grams (or about two-and-a-quarter ounces). The description that the ‘atoms’ were widely separated means that the particle density in the subtle body was low. This and the observation that the body could expand and contract suggest that the subtle body was composed of low density plasma, which could vary its density to some extent.

In 1988, Noetic Science carried out experiments on the largest number of patients and concluded that the human soul weighs 1/3,000th of an ounce. The experiments were carried out by East German researchers who weighed more than 200 terminally ill patients just before and immediately after their deaths. In each case the weight loss was exactly the same – 1/3,000th of an ounce. This is approximately 0.01 gram or 10-5 kg. The expert’s report on these experiments, co authored by physicist Elke Fisher, was criticised by Gerard Voisart, a leading French pathologist, who said that the weight difference between the living and dead could be accounted for by air leaving the lungs. However, Drs. Fisher and Mertens pointed out that this was considered in their calculations. Furthermore, they argued that the device they used to weigh the ‘soul’ had a margin of error of less than 1/100,000th of an ounce or 0.0003 grams.

“It occurred to us that the weight loss could be the result of an instantaneous physical deterioration,” said Dr. Fisher. “But after exhaustive study we agreed – that was not the case. The only possible explanation is that we were measuring the loss of the human soul or some kind of life force.” Dr. Becker Mertens of Dresden claimed in the German science journal Horizon that the only logical conclusion is that the existence of the human soul had been confirmed and its weight determined. “The challenge before us now is to figure out exactly what the soul is composed of,” he said. “We are inclined to believe that it is a form of energy. But our attempts to identify this energy have been unsuccessful to date.” This author’s Dark Plasma Theory, first published in 2006, proposes that these bodies are composed of low density plasma of dark matter particles. dARK PLASMA THEORY ESTIMATE Dark Plasma Theory holds that there is a halo of low density plasma around the Earth composed of exotic A sensational New york times news story from 1907 reports on Dr. Duncan McDougall's (pictured left) experiments to discover the weight of the human soul.

Minimal (dark) plasma cells developed in this ‘dark biosphere’ after Earth formed. Over more than 4 billion years these first cells evolved into complex dark plasma life forms. Being plasma life forms they exhibit features commonly seen in ordinary standard plasma. Heraclitus was probably close to the mark when he hypothesised that the soul was composed of a rare ‘finer substance’ which appeared like air or fire to him – two substances which, from a lay perspective, would bear a close resemblance to plasma. However, the reader should take careful note that these life forms are not composed of ordinary shortlived plasma but non-standard plasma composed of dark matter particles, which is invisible to most humans (just as dark matter is). Some of these life forms formed symbiotic relationships with members of the human species and co-evolved, integrating with the living carbon-based human body. On the death of the carbonbased bodies, the dark bioplasma bodies separate and return to their societies in the dark biosphere (i.e. Earth’s dark matter halo). It is these exotic life forms that are popularly called the ‘souls’ of human beings. In order to estimate the density and weight of the ‘soul’, i.e. the human bioplasma body, we must first estimate the density of dark matter particles on Earth.

Dark Matter Density Around Earth

The background galactic halo dark matter density is estimated to be about 5.35 x 10-28 kg cm-3. Xu and Siegel, from the University of Arizona, estimated the mass of dark matter within the Solar System (between 0.2 AU and 100 AU) to be 1.07 x 1020 kg (or 1.78 x 10-5 the Earth mass) (AU=Astronomical Unit. This is a unit equal to the distance of the Earth from the Sun). The mass of dark matter within the orbit of Earth (i.e. within 1 AU) was estimated to be 7.69 x 1019 kg. The corresponding dark matter density was approximately 9.65 x 10-23 kg cm-3. This is five orders of magnitude greater than the background galactic halo dark matter density. Xu and Sigel’s estimate that the dark matter density around Earth exceeds the galactic halo density significantly has been correlated by Stephen Adler from Princeton University.

Anomalies relating to accelerations, observed during fly-bys of spacecraft orbiting the Earth, suggest that the dark matter density around Earth had been significantly understated (as suggested earlier by this author). According to Adler the magnitude of the observed anomalies requires dark matter densities many orders of magnitude greater than the galactic halo density. Adler suggested that by comparing the total mass of the Earth- Moon system (determined by lunar laser ranging) with the sum of the lunar mass (determined by its gravitational action on satellites or asteroids) and the Earth mass (determined by the LAGEOS geodetic survey satellite), a direct measure of the mass of Earth-bound dark matter lying between the radius of the Moon’s orbit and the geodetic satellite orbit can be obtained. Based on this, the mass of Earth-bound dark matter must be less than 4×10-9 of the Earth’s mass, giving an upper dark matter mass limit of 2.32 x 1016 kg. (This is less than one-hundredth-millionth of Earth’s mass and therefore has negligible effects on gravity.) According to Adler, to explain the flyby anomalies, Earth-bound dark matter would have to be concentrated within a radius of about 70,000 km around Earth, within a volume of approximately 1.44 × 1030 cm3. For the dark matter mass within this volume not to exceed 4 × 10-9 of the Earth’s mass, the mean dark matter density would have to be about 10-14 kg cm-3. This is greater than the background galactic halo dark matter density by fourteen orders of magnitude. Based on the analyses above, it is reasonable to conclude that there exists a halo of dark matter particles around the visible component of the Earth within a An 18th century print depicts the soul rising from the body. 72 NEW DAWN ¦ Special Issue No. 15 www.newdawnmagazine.com Jay Alfred is the author of Dark Plasma Theory (formerly described as “plasma metaphysics”).

Jay has been researching dark plasma life forms since 2001. He is the author of three books on the Dark Plasma Theory: Our Invisible Bodies (2006), Between the Moon and Earth (2007) and Brains and Realities (2006), which are available on all Amazon, Borders and other online bookshops. He is the Research Director of Dark Plasma Life Research Organisation and a Consultant at ARPAST (Arkansas Paranormal and Anomalous Studies Team), a science-based research group that studies anomalous and currently unexplained phenomena. His organisation’s website is www.dapla.org. radius of approximately 70,000 km. Earth’s dark matter halo has been dubbed “Dark Earth” by the author and its attributes, based on the most recent estimates, compared to the visible Earth, are given below:

Dark Earth Visible Earth Mass 2.32 x 1016 kg 5.97 x 1024 kg Volume 1.44 × 1030 cm3 1.08 x 1027 cm3 Mean Density 10-14 kg cm-3 5.5 x 10-3 kg cm-3 Mean Radius 70,000 km 6,371 km The above estimates show that the dark matter halo would be three orders of magnitude or about 1.33 x 103 or 1,330 times larger in volume than the visible rocky Earth. This approximates with the dimensional relationship between the volume of Jupiter’s huge gas envelope and its tiny rocky core (the latter approximates the volume of the visible rocky Earth). In other words, we would expect an envelope of dark matter particles the size of Jupiter around the visible component of the Earth with a mean density of 10-14 kg cm-3.

Weight of the Soul

A man weighing 100kg is approximately 100 litres or 105 cm3 in volume. Based on a mean density of dark matter of 10-14 kg cm-3 (as estimated above) and the approximate volume of the human body of 105 cm3, the weight of the human bioplasma body (or the ‘soul’) is estimated to be: 105 cm3 x (10-14 kg cm-3), multiplied by the gravitational acceleration of 10 ms-2, or approximately 10-8 Newtons. However, in lay language, this is often taken to be 10-8 kg. Estimated Weight of the Soul: Based on Noetic Science Experiment 10-5 kg Based on Dark Matter Statistics 10-8 kg The weight of the soul, as measured in the Noetic Science experiment was 10-5 kg while the estimate based on dark matter statistics in this article is even lower at 10-8 kg. Considering that the dark matter estimate was the mean density, one should not expect a very close correlation. Bioplasma bodies may actually be denser than the surrounding environment (in the dark biosphere). The measurement in the Noetic Science experiment may also contain a certain percentage attributable to the weight of unaccounted ordinary matter. Looking at the broad picture, therefore, these estimates can be considered quite close. We hope that this finding will motivate further experiments to weigh the human soul using more sensitive scales in controlled settings.

Well, If attention (a tention) is to be defined as whatever it is you pay attention to, then vibration is simply a state of attention of a certain frequency. Energy defines you, not the other way round. Putting an arbitrary number to the 'weight' of the soul is utter nonsense to begin with. When we have absolute control over gravity, matter will be of the mind. If thats your definition of attention then I have to assume your understanding of vibration is equally wrong or made up. Attention is the concentration of your mental awareness on an object, not the object itself like your definition wo... [More]

I find it quite amusing, that I have just finished reading Dan Brown's newest novel, the Lost Symbol, in which one of the characters claims she proved the Human soul has weight - and then I run into this thread.

my humble opinion..... Number one, the McDougall experiment was done in the early 1900´s with i think about 5-6 patients, and there needs to be a new controlled study with today's technology Things like the weight of the lungs before and after, plus as many other parameter's as we can possibly measure...this seems to be a great way to investigate one of the biggest mysteries left!! This has been a great thread/forum for a couple of really good ideas, the measuring of the fetus for example, really good idea for the pro life/choice movement, but in this case its only gonna raise the question of ...

My theory is that the building blocks of the universe, simply worded, is energy. Thus if we have a soul its just another "form" of energy, as Einstein discovered there is a correlation between energy and mass, thus the soul MUST have a weight/mass......but wait....only if it exists. Wait, so electricity has mass? Got a Giorgio Tsoukalos vibe from that statement. I really think there is a more natural explanation for that 21 gram average taken from 6 people.

Agreed, its very possible, maybe even more plausible, that there is a natural explanation for this phenomenon. Thus the need for a new investigation. To measure something means when need a point of reference, if its unmeasurable by today's scientific standard or in other words outside our realm of understanding, then the question itself becomes redundant.

On my early 20s I had just decided to study biochemistry. Long days of physiology, biology, physic caught me in those old buildings of the university with hundred of student listening to a professor with some aura of rock star performing in front of a current audience of nerds. I’ve never imagine that in my enlightenment mind I would be pushed to think in the paranormal thanks to those classes that found us more than one time at the edge of the knowledge of the science that planted the seeds that inspire my today research.

In all fairness, it's more a matter of a lack of better words. New definitions are assigned to "energy" and "vibration", and are established strongly enough so that, in a way, it isn't misuse any more than it's just an example evolving language. I'm still not sure exactly what "vibration" is supposed to mean in the new age context, though. Many people link astrology and Edgar Cayce to new age stuff, but I dont know how you even define someone who's a "new age believer" of sort, maybe someone who listen whale sound tapes like Homer did in Simpsons? I do that too though sometimes... I guess ther... [More]

After reading all these posts, I was left wondering about the people who allege the ability for Out of Body experiences and whether or not there have ever been any studies on the difference in their weight whilst their consciousness, or "soul", was on vacation?

Hi! I am very interested in this kind of experiments and i wonder, has anyone found an actual article regarding this kind of experiments? i am working on a simmilar experiment myself and need any information about the measurements done in the past. somehow i find it very hard to find a single article... thank u for your help!

If you fart in outer space...do you gain weight or lose weight? If you are in outer space traveling at the speed of light...and you turn on the headlights...do you slow down or speed up?
