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?

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.

I'm gonna go out on limb and say they're no longer with us.
Yeah I don't think you're very far out on that limb. The likelihood of successful rescue is extremely low.
I can't really believe anybody would spend $250K on a submarine expedition with the guy in charge of Ocean Gate, and his incredibly cavalier attitude toward safety.
Yea when I first heard about this I kinda just wrote them off tbh. The ocean is massive and moving, plus they're in a glorified, malfunctioning, soup can.
I've never heard of the guy, but I can imagine based on that description jeez.
"It's all apart of the experience" probably.
Maybe for a camping trip, but not this lol. Your already completely and literally out of your element.
I've heard somewhere it's easier and safer to explore deep space than to explore the deep ocean.
I wonder...is that only because we use probes? Or is it something to do with atmospheric pressure? Like I'm assuming water is heavier than space so even if you had a space suit on underwater you'd still get crushed or eaten by some big ass squid.
I'd love if a scientist could weigh in on this.
So, I'm not a scientist, but I've watched plenty of space and ocean documentaries because it's interesting to think about, so I'm pretty qualified, right? So, space is actually the opposite of heavy. It's a vacuum, so the vessels designed to operate there have to deal with holding pressure IN, instead of out. Also, there's no big ass squid in space to eat you, lmao.
even if you get a hole in your space suit you'll live for a minute or so before freezing/dying of lack of oxygen. Get a pin hole in a sub down by the titanic and it will basically instantly implode killing you before you even knew something happened. space is far easier other than getting there and the radiation you need to protect against long term.
Yes you are qualified, cause you summed it up pretty good! Summary: ocean is sketchy af!
My layperson understanding is that with space you only have to have something robust enough to keep the atmospheric pressure in (as well as other considerations of course) which allows for less robust materials. For deep sea exploration you need something robust enough to keep the water pressure out.
For additional info: 10 metres of water depth is approximately equivalent to 1 atmosphere's worth of pressure (ATM) - so 50 metres is 5ATM and so on and so forth. So theoretically a submarine would have to combat hundreds of ATMs of pressure, whereas a space craft only has to combat at most a couple of ATM.
In the ISS a minor hole can be patched pretty easily and quickly as it's a slow leak of air out, however if a leak occurs in a submarine the results can be explosive and deadly.
To add a little: when a thing fails in compression (submarine), it's usually unpredictable and catastrophic. When it fails in tension (spaceship), it starts slow and fails in a predictable way.
Tension is also much easier to calculate when you're designing structures. Engineers will often go out of their way to make sure that tensile failure is the controlling failure mode, just to make sure that we don't have to fuck with compression.
Thank you, yes this is what I had in my head, I appreciate you wording it properly, with examples!
I mean just superficially space is 0 atmospheres of pressure and sea level is 1. Compare that to the many hundreds of bars of pressure at the bottom of the ocean.
The distance is greater when exploring space but there's nothing there. No currents or waves or storms or sharks... Just nothingness.
I mean everyone says "omg they're crazy", but it's so easy to say that, and all of us have at least a few things that we'd be willing to do that an onlooker could point to and say "lol why do that when you might die".
There's nothing wrong with taking an informed risk, and it's really up to you what kind of risk you're comfortable taking. Most of these people seem to have a consistently high risk tolerance, and three of them were very experienced, so I don't think it's fair to call them "stupid" or "idiots" just because your risk/reward assessment doesn't line up with theirs. If that was their idea of living the best life possible, then that's good for them.
I'd also say that the majority of people in life aren't as happy as they could be because they're too scared to let go of convenience and familiarity. People turn down dream opportunities because it means moving to a different country, they stay in jobs they hate because they're scared of what comes next, they don't travel to places because five years ago someone died there, and they stay in unfulfilling relationships because they hate the thought of being alone or having to meet new people. So if you're the kind of person who basically spends their life on the couch with the same old people in the same old place eating the same old food watching the same old shows and you dream about what could've been, I'm not sure you have the right to lob criticisms at people who chose to get up and do stuff.
I get what you're saying about taking a calculated risk - like going for a bungee jump or paragliding or bouldering. However, the more you read about this particular craft the more you realize how much they ignored highly standard safety procedures and design. So I feel like the people criticizing are less saying "why bungee jump when you could die" and more saying "why would you bungee jump without a cord and pay 250,000 dollars for the privilege."
