no one died yet...
- redtexture 3y agoNow all dead. Apparently on the way down.
- aredox 3y agoEverybody was already dead.
- CydeWeys 3y agoThey could all easily already be dead. We simply don't know.
- wkat4242 3y agoIf indeed that viewport collapsed at 4000m as the article suggests, they probably didn't even have time to realize they were dying.
- euroderf 3y agoRelatively, exceedingly merciful.
- misiti3780 3y agoHow long would it take to get down to 4000m though, didnt they lose contact like 1 hour in?
- methodical 3y agoThe ascent and descent to Titanic is about 2 hours one-way. The exact time they say they lost contact was after around 1 hour and 45 minutes. It was likely at or close to at the depth of Titanic.
- Sohcahtoa82 3y agoThe article says they were going for 4000m, but it was only rated for 1300m. That would imply a collapsing somewhere between the two. Also, would the body, being mostly made of water itself, really get crushed instantly? I would certainly expect the pressure to squeeze all the air out of your lungs. I know nothing about how the body behaves under high pressure.
- kadoban 3y agoI looked up a depth to pressure calculator, at even 1300m, the pressure is 1892.67 psi. "psi" is pounds per square inch, and a human has ballpark 3000 square inches of surface area. So to get a (very) rough approximation, picture what would happen if you squeezed a human with 3000*1892 pounds of force. Or try not to picture it, because I imagine it being pretty gross.
- flangola7 3y agoMythBusters did this with a realistic (pig?) manikin. Pretty gross, yes.
- xuf 3y agoFor anyone that would want to see that: ‘Mythbusters - Compressed diver’ https://youtu.be/LEY3fN4N3D8 https://youtu.be/LEY3fN4N3D8
- justinclift 3y agoYeah. Reminds me of this underwater pressure awareness training video on youtube from a few years ago: https://www.youtube.com/watch?v=PXgKxWlTt8A https://www.youtube.com/watch?v=PXgKxWlTt8A (if you're squeemish, don't click that link) Industrial divers / welders / etc get all kinds of training to avoid that stuff, for good reason.
- j2bax 3y agoI'm sure they never imagined this video being paired with an incident like this but wow, their joyful and excited reactions (with no context of the lead up to this experiment) feels really morbid/sick. I realize they were trying to prove a myth and it worked, but still found it unsettling.
- anigbrowl 3y agoI'm Hollywooding it here, but I bet it develops crack lines before collapsing. Most things in nature fail slowly, then all at once - think of standing on an iced-over puddle or pulling tree limbs.
- wkat4242 3y agoI think 400 atmospheres of pressure change the dynamics a lot here. Perhaps there might be a hairline crack that makes a window shatter when it's hit with a hammer. Except the hammer impact is constant. I don't think there would have been a lot of time.
- anigbrowl 3y agoI don't mean that it had a crack in it, but that it developed one as a precursor to total failure. My experience of physical materials is that they almost never just atomize, rather there's a weakpoint from which the failure cascades. I'm envisioning a process that might only last a few seconds, or be measurable in milliseconds.
- archi42 3y agoThe forces are immense and act all the time. In your daily life, you don't usually have that kind of system, so this feels counterintuitive. Press against a solid object gently with one hand on each side, then suddenly yank away one hand. The object will be accelerated gently. Now do that with all your strength and send the object flying through the room in no time, with a few dozen kg of pressure. Now imagine that you could apply hundreds of tons of pressure. In such a system, every change will be nigh instantaneous.
- anigbrowl 3y agoI understand the physics just fine, thanks. I'm not disputing that it will be 'nigh instantaneous', I'm talking about how it fails. You and downvoters are also neglecting the fact that the submersible isn't suddenly teleported to/near its destination at which point it suddenly fails. It gets there slowly, passing through its safety envelope on the way.
- c00lio 3y agoOxygen is just about running out in the next few hours, they don't seem to have had any sonar contact, no cable or underwater phone. Getting something like a DSRV (which wouldn't really help if they are at ground level there, because it cannot dive that deep) there will take at least a day. Even if they are still alive, their chances of rescue are nonexistent.
- TimothyBJacobs 3y ago> Oxygen is just about running out in the next few hours, Official reports have been saying 40 hours a few hours ago.
- jacurtis 3y agoYes there were oxygen scrubbers on-board that had an estimated endurance to provide clean air for about 5 days for 5 people. It has come out that it is wildly untested and optimistic estimate. The longest mission they had conducted onboard was 12 hours. So the theoretical limit may not be realistic. If there was panic onboard, that would increase oxygen usage dramatically, which could cut as much as 25% off the estimate (which is nearly a day in this case). In other words... it is grim.
- jvm___ 3y agoThe best 'find things on the bottom of the ocean' gear is usually on a ship somewhere, but just happens to be in-between ships, but is on the Jersey islands in the English Channel. Except it still needs a military cargo plane to retrieve it, deliver it to Newfoundland and be moved by ship on location. Time isn't on their side.
- jethro_tell 3y agoWell, it's schrodinger's submersible at this point.
- civilitty 3y agoTalk about a collapsing wave function! (Or don't)
- aleph_minus_one 3y agoPrevent the collapse of the wave function to prevent the possibility that the occupants are dead.
- deleted 3y ago[deleted]
- jethro_tell 3y agoWell, they're lost at sea until found if I'm not mistaken.
- quietbritishjim 3y agoIf the viewing window collapsed then they would have been pretty much instantly compressed to a paste.
- jacurtis 3y agoYeah, everyone calculating oxygen rates is a nice optimistic view on the situation. I think occams razor suggests that they experienced a breach or defect in the viewing window (or possibly the hull). At the pressures they were at, it would have been over for them, before they ever even knew there was a problem. The pressures are so great, that they would have assimilated into the water instantly. For what its worth, as sad as that sounds, it is possibly a better fate than the alternative of suffocating to death for 4 days in complete darkness (which is exactly what happened to 23 crew members aboard the Kursk russian sub back in 2000 [1]) [1] https://en.wikipedia.org/wiki/Kursk_submarine_disaster https://en.wikipedia.org/wiki/Kursk_submarine_disaster

- saberdancer 3y agoI also thought they suffocated but it seems more likely that they died in a fire. "Analysts concluded that 23 sailors took refuge in the small ninth compartment and survived for more than six hours. When oxygen ran low, they attempted to replace a potassium superoxide chemical oxygen cartridge, but it fell into the oily sea water and exploded on contact. The resulting fire killed several crew members and triggered a flash fire that consumed the remaining oxygen, suffocating the remaining survivors."
- inimino 3y agoApparently they were trying to fix the cartridge and the officer lost control of it and was killed instantly, some of the others dove under the water and survived the fire, but as the fire had consumed all the oxygen, it didn't matter. How they figured all that out from what they hauled up, I can only imagine.
