No such thing. Ask away!

!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:

Rules (interactive)


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.

For those who are unaware: A couple billionaires, a pilot, and one of the billionaires' son are currently stuck inside an extremely tiny sub a couple thousand meters under the sea (inside of the sub with the guys above).

They were supposed to dive down to the titanic, but lost connection about halfway down. They've been missing for the past 48 hours, and have 2 days until the oxygen in the sub runs out. Do you think they'll make it?

That depends on if their CO2 scrubbing lasts longer than their O2 supply. Your body can't actually feel a lack of O2, the feeling most people associate with suffocation is actually your body detecting a build up of CO2 in your blood. If they can keep scrubbing the CO2 out of the air after they run out of O2 then they'll just start to get lightheaded, kind of drunk feeling, tired, and eventually just pass out and die. You actually barely feel it happening which is why O2 sensors are so important when working in poorly ventilated confined spaces. I know this first hand because I work with bulk liquid nitrogen and I've damn near knocked myself out a couple times via an inert gas cloud. One moment you're perfectly fine, then you just start to black out and it dulls your senses so much that you don't even have the brain power to process what's happening. Them running out of oxygen more slowly will extend that process a bit but it still isn't a painful process and the thought numbing effect from your brain running out of oxygen keeps it from even feeling particularly alarming.

So as long as they can keep scrubbing CO2 then at least they won't die a particularly "unpleasant" death. That is assuming the sub didn't just pop from pressure like you said.
