World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

So, I understand that because water is not compressible, animals without air in their bodies are safe at such high pressures in the deep sea, but what I'm wondering is what would it look like if a human in the deep sea was suddenly exposed to those pressures, as would happen if a submarine rapidly pressurizes? I know the lungs would collapse and whatnot because the air would be pressurized into I'm guessing a liquid, like how propane sloshes when under pressure in a tank, but what else? What causes the instant death? Maybe the water shoots into nose/mouth so fast it acts like a bullet and applies a bunch of force to the walls internally?
These are styrofoam cups that've been crushed by the pressure at the bottom of the ocean. The water isn't looking for your nose, it'd just crush your outsides into your insides until you hit a relative density, like the cup, but not as pretty. The air in your lungs would instantly compress and heat to several thousand degrees C, turning your insides back into your outsides. I think.
Holy shit and all of that happens within 2 nanoseconds I think? So that's why the victims in that submarine wouldn't even know it already happened because our brain takes 4 nanoseconds before we could process that pain.
There's a big chance they've all passed out from lack of oxygen by the time this happened. It's instant death either way.
The velocity of a catastrophic implosion like that would exceed Mach 2 (686 m/s). Nerve conduction is about 50-60 m/s. Dead before they knew anything was going wrong.
