He weighed the bodies of 6 people who died: He discarded 2 of the measurements, 1 showed a drop in weight, 2 more showed a drop that increased as time passed (was the soul squeezing out?) and 1 showed a drop that reversed and then happened again (did the soul forget something and pop back in?) So in all it was a flop.

By the way, why do you think it was made illegal to way people when they die in 1908?

We did a video on this, if anyone wants more details. it's admittedly not very good since we had two days to film six videos, but THE INFO IS THERE.

Will someone please do WLD (weight loss at death) tests with a very sensitive weight scale (model KG10 10,000×0.1g) during euthanasia of animals (that weigh less than 22 lbs.) to test a prediction: The higher the WLD, the higher the thought level. So a reptile should test lower than a mammal, and so on. Let's open a window into the 5th dimension.

Brave for the experts screaming how it's impossible because they got offended

A deep knowledge of science will make you belive in God and a shallow knowledge of science will make you an atheist.

What if the 21gram is caused due to the bloood circulation which makes it a dynamic load on the body and when the body dies the circulation stops rendering the blood static, hence the decrease in weight albeit a small amount. btw I do believe in soul but before we draw conclusions we should consider every possible physical explanation.

The experiment was totally a joke.
One of the patients lost weight but then put the weight back on, and two of the other patients registered a loss of weight at death but a few minutes later lost even more weight. One of the patients lost "three-fourths of an ounce" (21.3 grams) in weight, coinciding with the time of death. MacDougall disregarded the results of another patient on the grounds the scales were "not finely adjusted", and discounted the results of another as the patient died while the equipment was still being calibrated.

Clarke criticized the experiment's validity. Clarke noted that at the time of death there is a sudden rise in body temperature as the lungs are no longer cooling blood, causing a subsequent rise in sweating which could easily account for MacDougall’s missing 21 grams. Clarke also pointed out that, as dogs do not have sweat glands, they would not lose weight in this manner after death.

We assume that WHATEVER that creates our Universe-Reality is God in the final-ultimate…..There could be INTERMEDIATE GODS, that fully created us
and yet is not the "final" God….Just because humans are really different from Other Animals does not automatically make you the dearest product of god.
We humans are searching and forever searching, but we have a problem with aggrandizing ourselves….

I have such an idea that I can prove that if there is any thing in this world like ghost spirit or not, I cannot speak English, I can only speak in Hindi. I am from india my mobile number is this ( WhatsApp number ) +91 9997921424 . But I need a 10 by 10 lens for this, which I do not have, nor do I have enough money to buy such a big lens. If anyone gives me such a big lens, I will proof everything whether there is such a thing as a soul or not. And I will also proof whether an atheist is right or wrong.And which religions are wrong and which religions are from the same religion? All these religions are wrong.If I am not able to proof this, then I am ready to go on the cross.Not only this, I will also prove from this that what happens when we read any such thing like a dua or a mantra, etc. Are any gods or angels coming to protect us, all these things are nonsense.If any country of the world gives me this country, now whatever I need, then this discovery will be written in the history of that country which will be one of the greatest discoveries in the world.For this I am willing to bet with all the atheists of the world as well.But I do not know how to speak English, I can only speak Hindi. I am from india I have given you the mobile number above.If anyone gives me this, then call me on my mobile number and talk in Hindi. Thanks

the universe operates in liquids and various forms we consider elements. sperm cells contain the components to help create life, yet require an egg.. i dont know the whole process scientifically, but spiritually that could be seen as a spirit attaching to a shell.
emotions all operate and fluids, and blood and everything contains the basic building blocks of life.. when the body dies, the fluids vacate the body, and evaporate so science and religion could really be saying the same thing

Anyone tried to weigh it now days?

Science Series May 10, 2020 - 11:50 PM

According to Hindu culture soul haven't any weight it's called 'suchma shareer ' you British people why you thinks that soul have weight does light have any weight no ( I know it shows dual nature) we don't believes that soul is a solid object that is present in somewhere in our body

21 grams

Is it true they captured a soul in a box and it did weigh less than an ounce.hence it is common for angels to possess birds.its the mass/ matter/ volume equation

This is one of the best episodes out there and one that still challenges science today. This man’s scale is still used today as the most sensitive scale known to mankind

Something was not correct regarding the experiments done to determine whether the soul weighed 21 grams.

it was never repeated scientifically ever again successfully with the same results, at the very least, never published as being scientifically successful.

We know that the soul does not have mass. It is this phenomena that allows the soul to travel anywhere within the mind and body of GOD, essentially by travelling without moving. Some call this phenomena "out of body experiences", or "Astro-Travelling"

Of course, that only applies to the current relative way the soul is perceived in our realities. It is better described as the soul having no mass relative to our physical mass. In essence the soul is Quantum entangled with the mass of our physical bodies.

The soul is quantum entangled the same way that the future and the past is quantum entangled with the present.

The real phenomena would be, what would happen if our souls gained mass relative to our physical mass in our realities…?

For one, we would no longer have the freedom to traverse the mind and body of GOD, and we all know what that means, Hell…

Believe it, or not!

Perhaps if someone was possessed by a "demon" and then exorcised, their weight may drop by 21 grams.

It may be possible that a demon weighed 21 grams when it released the persons soul under a mild blessing from a priest during the passing away.

This may explain why the experiment was never successfully repeated scientifically again.

The chances you would try the experiment again knowing if a person was possessed or not, are millions to one.

Believe it, or not!

god does not exist

Mark H IIL June 15, 2021 - 3:50 AM

If a soul can be measured in 21 grams then there would undoubtedly be evidence of a physical soul because mass is a measure of matter and matter is inherently physical. This is bullshit
