21 grams. That is what our soul weighs. I kid you not. But, doubters, don't take my word for it.
I'll try to condense this down as I like to write my blog in the form of a short story instead
of a novel. Bear with me as this is about the things we can't see or quantify. Until 1901, that is.
Dr. Duncan MacDougall sought to measure mass lost by a human body at death. In his quest to prove his hypothesis that the soul had mass when it departed the body, he took into account body fluids, weights, air, etc. He measured patients he knew were dying on an industrial scale, which was reported to be sensitive to 2 tenths of an ounce. On nearly all of the patients, when they took their last breath, the weight loss was the same. 21 grams.
Dr. MacDougall later measured fifteen dogs with similar controls and circumstances and reported the results as "uniformly negative". With no perceived change in mass, he took the results as confirmation that dogs did not have souls. It was later conjectured that Dr. MacDougall was in fact sacrificing experimental animals; created a scandal when published by the New York Times.
Be that as it may, his colleagues said they couldn't replicate his studies, and therefore, found his experiments unscientific. Now, that might have been the end of the story, until a modern day anesthetist used quantum physics to study what happens with consciousness, proto-consciousness and the rest of the story will come in the next post.
