Summary:
- The "21 Grams" experiment was a controversial study conducted in the 1930s that aimed to measure the weight of the human soul by weighing people before and after death.
- The experiment was conducted by Dr. Duncan MacDougall, who believed that the soul had a physical weight that could be detected using a specially designed bed scale.
- The results of the experiment were inconclusive and have been widely criticized by the scientific community, as the study had significant methodological flaws and the findings were not reproducible.
