The Experiment That Tried to Weigh the Human Soul
It’s a little complicated to weigh a dying person on a hospital bed, but that didn’t deter Duncan MacDougall. In the early 20th century, MacDougall’s unique bed-scale detected that 21 grams left the human body at the moment of death. He had finally discovered it: the weigh of the human soul … or so he…

Would Permanent Daylight Savings Time Really Improve Our Quality of Life?
Whether you’re pro-Daylight Savings or pro-Standard Time, the science is clear: Switching *between* the two every year is terrible for human health. So why haven’t we stuck with one system all year? The answer is both scientific AND political. Hosted by Annie Colbert Reported by Tom Hawking Edited by Avital Oehler Written and Produced by…

Let’s launch our garbage into the sun!
Ummm, no. Earth is messy. So can’t we just send our junk somewhere else? Aside from the moral quandaries raised by such poor stewardship of our already disheveled solar system, Earthlings probably haven’t made a habit of beaming literal garbage into space yet because we simply can’t afford to.

God created this universe so that he could live in it as life, everywhere possible.
There is no I. I am a part of God that will never die. Soul or not.

Nah, it was the Cosmic Whelk who invented the universe. He did it one Tuesday evening after a particularly spicy vindaloo. May his Holy molluscular univalveness endure for eternity. Asnails.

Really, and which of the 2000+ “god(s)” are you talking about? Is it Hera? Thor? Yahwey? Vishnu? What part are you? How did you determine this? How did your “god” create the universe? What evidence do you have for ANY of this that I can test and verify for myself?
See, we’re talking about science and reality here – if you wanna believe in your fairy tales great, go right ahead – but when you tell others the intelligent of us will want EVIDENCE – got any? No? None? Really, none? Oh, some bronze age book of fairy tales written by nomadic goat herders – really?

So 21 grams of what exactly? What is the carrier, or at least the physical correlate to a soul? And via which channel is it emitted from the body? I mean, if we can reliably replicate the phenomenon, the next step is trying to THOROUGHLY explain it.

Which of course you can’t do since the “soul” doesn’t exist other than a concept.

And that’s precisely the problem. Air HAS weight. If he didn’t measure any difference, then it’s due to his measuring method.
A football without air weighs less than a football with air; it’s a matter of the accuracy of the instruments.
So if he can’t even achieve that level of accuracy, how does he expect to weigh something like a soul?!?

Well given it doesn’t exist he’s not going to measure that anyway…

This is the most r/midwit or r/athiest type of bait I’ve seen since the 2010’s🤣
Just smart enough to “call out” the giant, invisible, all-powerful entities not being there; just stupid enough to think they’re somehow the first to notice or not comprehend the reasons they’ve spread across every culture in history… classic.

What about those soul-less people running around us and making everyone’s lives unbearable? Their souls surely weigh nothing, dead or alive!
@Haggie

Even if dead bodies do weigh less, it doesn’t prove the existence of a soul. It only proves that some amount of weight is lost at death. They may as well claim that the weight loss at death proves that God exists.

If this is an example of what Popular Science has become I’m glad that I haven’t subscribed to it for decades! What a poor article and poor journalistic effort! Briefly: She says his experiments were flawed but doesn’t say how and after 100 yrs if someone has the knowledge and experience to determine how his experiments were flawed then that means they know how to conduct an unflawed experiment and so why haven’t they? Next, she says his work was debunked but doesn’t mention the man’s name who supposedly debunked the 21 gram experiments or how he supposedly debunked them. I’d like to know his exact methodology and any reference materials etc and a step by step account of how he debunked them. Then also I want to know who debunked the debunker? The article mentions one of the 6 people dying while he was adjusting the scales. Why? To add filler to the story? Why mention later things he did like using X-rays, more filler? Small sample size? Yes well ok. That is valid. But after 100 years why hasn’t anyone else added to the sample size? I’m sure if you offered terminal patients or their families some cash incentives to help pay their medical or funeral expenses etc that you would have an overwhelming supply of volunteers to participate in such experiments. And using today’s technology we could get much more accurate measurements.
