!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

You get heavier, totally anecdotal evidence on my part but I've stepped on the scale in the morning, let a glorious one rip, and the number went up by 0.1.
I am not saying that I gained 0.1 lbs, just that afterward the scale rounded it up instead of down.
Sounds like solid scientific research to me, I will now carry this nugget of information as an absolute fact.
A balloon full of helium has more mass than a balloon without helium, but less weight https://en.m.wikipedia.org/wiki/Mass_versus_weight.
~~Methane weighs more than nitrogen (70% of atmosphere); you lose weight and mass. Molar mass of nitrogen 7; methane 16. ~~

Edited to comment about mass: Except that a) methane is leaving the body and is not necessarily being replaced; the volume is simply taken up by a contracting colon and b) methane may be less dense than air, but it does contain fecal particles as well, which are tiny but still heavier than air.
At room temperature methane is lighter than the atmosphere on Earth's surface, not heavier.
However, pressurized in your body it may he heavier. I see no studies measuring this.
This guy farts.
But he doesn't let it weigh him down.

That's not true. A balloon full of helium has more mass and more weight than a balloon without helium. Weight is dependent only on the mass of the balloon+helium and the mass of the planet (Earth).
The balloon full of helium displaces way more air than the balloon without helium since it is inflated. The volume of displaced air of the inflated balloon has more weight than the combined weight of the balloon and helium within, so it floats due to buoyancy from the atmosphere. Its weight is the same regardless of the medium it's in, but the net forces experienced by it are not.
Is there a measure for the force exerted on the ground for something then? Such that a balloon would be 0
Methane is lighter than air. Methane is indeed ~16 but nitrogen has atomic number 7, molecular mass ~14, and the molecules are N2, so ~28.
The molar mass of elemental nitrogen is 14, not 7. However, its equilibrium state in our atmosphere is as N2 which has a molar mass of 28.
One of those interesting facts I like and will bring up sometimes, the pound and the gram aren't just different scales for the same thing since the pound is the measure of weight or force and the gram is the measure of mass. In the vast majority of cases most people encounter in everyday life they'll be roughly interchangeable if you convert, most things being done at roughly 1g with extremely minor variations for location that won't come up unless you're doing super precise measurements, buoyancy won't come into play for majority of things most people are measuring in day to day, etc.
The pound is actually a unit of mass. What you're thinking of is the pound-force.
You misspelled kilograms and Newtons.
Sharting makes you lighter for sure
Only if you're naked.
I shit your pants
bit rude innit
~~Farts are mostly particulate. So, you'd be lighter.~~
Edit: I did not have "researching farts" on my dance card today, but here we are - I have inadvertently repeated a misnomer. While flatulence can be accompanied by aerosolized liquid, microbial elements, and particulate fecal matter, our gut is actually much more efficient than previously thought at separating gasses. Healthy farts do not contain a significant amount of non-gaseous material. A tiny bit of such material would weigh more than the gaseous content, hence the misnomer that farts are mostly liquid and solid material by weight.
As the gasses contain hydrogen and sometimes methane, they are indeed lighter than air, on average. They may also contain sulfides and carbon dioxide that are heavier than air, but in smaller quantities.
So, according to flatus experts (yes, that's a thing), yes, farting on Earth likely makes you heavier.
For those who want to suffer as I have, here is a fairly comprehensive article on the matter.
m.. mostly?
On top of the fact that the gases have lower molecular weights than air, they are also at 37°C or 310K ie ~5% lighter still.
Please discuss this with your doctor.
I think "mostly particulate" would have to cause visible exhaust fumes 😅
As a homogenous blob, you would become lighter and denser.
Makes me muuuuuch lighter. At least that's the feeling in my belly!
That is less pressure, not weight.
Methane is lighter than air, so farting makes you heavier.
But not in any measurable way.
Methane is lighter than air
Objection! ;-)
This comparison is not relevant, unless you take in as much air immediately as you have just pressed out.
Would you now please show us how you do that?
If it's lighter than air, it's lifting you while it's inside of you...
If it's not there, it's not lifting you, and you're heavier.
Think of a balloon that is so old it doesn't rise anymore. It just stays neutrally bouyant. In this case it's even less than that. It is a completely and totally negligible amount of difference. But while holding a fart you're technically a very shitty balloon.

But you don't know at what immmmense pressure I can hold my farts!
There is a limit beyond which it will all have dissolved into your blood stream.
Higher pressure decreases the relative volume of the gas, increasing its density and reducing its buoyancy. What you need is extra voluminous farts in an otherwise nearly empty, low pressure digestive tract.
Unless you are in a vacuum chamber, then it makes you lighter. Also you would be dead.
It depends on how pressurized it is. And clearly farts are pressurized.
I think, you get lighter from the thrust, and the loss of those rarefied substances also reduce your mass.
