That the human soul is actually truly something that exist, I always wondered what is the soul or is it measurable, what is it made off, then I came across this piece on wikipedia while doing my research. In 1907, a Massachusetts doctor named Duncan MacDougall proved the existence of the human soul. It’s called 21 grams Theory.
He measured the weight of a person at the moment of death. He had 6 patients all of which experienced weight loss with the average loss of weight being 21 grams…
He recorded not only each patient’s exact time of death, but also his or her total time on the bed, as well as any changes in weight that occurred around the moment of expiration.
He even factored losses of bodily fluids like sweat and urine, and gases like oxygen and nitrogen, into his calculations. His conclusion was that the human soul weighed three-fourths of an ounce, or 21 grams.
The results of MacDougall’s study appeared in The New York Times in March 1907.
The idea that the soul weighs 21 grams has appeared in novels, songs, and movies — it’s even been the title of film Dan Brown described MacDougall’s experiments in some detail in his adventure yarn The Lost Symbol.
