    Grams
AI Thread Summary
The discussion centers on the movie "21 Grams" and the concept of measuring the weight of the soul at the moment of death. It questions the credibility of the film's premise, highlighting the improbability of accurately measuring weight changes at death. The conversation emphasizes that the soul is metaphysical and cannot be quantified by physical measurements, which is a fundamental limitation of physics. Additionally, it suggests that any weight loss at death could be attributed to the expulsion of air from the lungs rather than the departure of a soul. Ultimately, the view presented is one of skepticism towards the existence of a soul or an afterlife.

Im curious about the movie 21 grams

thanks
 
Physics news on Phys.org
Just how many people do you suppose have died while laying on a scale senstive enough to make this measurement? How many people have ever measured their weight to this accuracy, and know it to that accuracy at the moment of death so as to be able to detect this change in weight?

I think the answer to both these question is exacly 0.

Why do you think anything that is said in a movie is in the least bit crediable?
 
i don't know maybe you are right and the soul doesn't have to respond to gravity

maybe that would mean that souls don't have to respond to time either
 
IMHO
The soul is metaphysical, it is not of the world of measurment. I as a physisist am only able to deal with measurments, with and must have measurements in order to understand the PHYSICAL universe. This is a fundamental restriction which PHYSICS will never overcome. The similarity of the emphasised words in not cooincidental. Physics is the study of the physical universe. The soul, or essence of life, is not measurable, there for not a part of physics.
 
I suppose when you die, your lungs collapse. This could account for a weight loss as air is expelled from the lungs.
I personally don't believe in God, or a soul. I believe that when your gone, that's it. You've had your chips.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
