Such attempts have been made in the past; the conclusion was that the body loses about 23 grams of weight at the time of death. (This is a tremendous amount of energy.) The scientific community did not accept the findings for various reasons.
Incarnation attributes to the human soul's energetic qualities. Clinical death means that the soul leaves the body, hence the perception that death brings about a (very slight) change in the body's mass. According to Einstein's well-known formula, E = MC², even a few grams of mass are tremendous energy!
- Today in the 21st century, with the latest technologies, it is possible to conduct a controlled study of what takes place in the moments of clinical death. Special sensors and cameras may even capture images we have never seen before. I believe a wealthy billionaire on the verge of death would be willing to fund such research if the finding approves that the human soul has mass! This will be a most sensational scientific revolution.
The question of what happens after death has preoccupied many scholars for generations. Quite surprisingly, no in-depth scientific research has been conducted on the subject.
I believe a determined and curious billionaire, not necessarily on the verge of death, will want to advance such research that will perpetuate his name forever.
