How fast did the people in it die?
Of course once the sub filled with water they would die instantly because it would reach insane pressures (300-400 ATM or 5800 PSI)

Less than 4 milliseconds. They didn’t feel a thing.
To add context here, it takes your brain somewhere around 100ms to detect and then another 250 to process pain. So 4ms is not only fast, it’s absurdly fast.
To get a sense of how fast it is, go ahead and stub your toe, the time it took to feel it is 100 times longer.

I just take solace in the fact that they probably just snapped out of existence instead of having to slowly die in a dark tube over a few days.
I had seen a comment saying human to salsa in 4 milliseconds. ಠ_ಠ
And because what failed was the carbon fibre composite pressure vessel, it probably didn’t even give any warnings to make them worried. It would be like squeezing a glass bottle, everything will be perfectly fine until it just instantly shatters.
Sometimes glass will give a ‘click’ as a crack starts. Not sure about carbon fibre though.
Did some math based on that number since it seemed pretty insane. That would mean that each side of the outer hull would have been moving inward at about 425mph by my estimate. Seems slower than I would expect by that number, but 4ms is hella fast.
Do you think they died from the water rushing in and hitting them unconscious?
They died by being crushed with enough pressure such that the air inside the sub ignited ie compressed so much it essentially exploded. Death was instant.
I know a diesel engine works off compression, but it has a fuel. All fires must have oxygen, fuel, and heat. What fuel would they have in the titan to ignite?
Everything (including the passengers) inside the sub could have been fuel for combustion had there been time for the reaction to take place. If I remember correctly the interior of the sub could have temporarily been hotter than the surface of the sun during the implosion. Pretty sure just about everything burns at those temps. But the collapse and gas release from the hull happened so quickly I doubt there was time for anything to ignite.
If you compress a gas enough it will get hot enough to ignite. Google “fire pistons”.
It’s also why airplane tires are filled with nitrogen instead of air. On landing, the high pressure and heat can cause the oxygen in air to combust.
Ex-people, plastic and so on. With a small room’s worth of air it wouldn’t have burned long, though.
More significant is just how hot it would get as it collapses. When you suddenly compress an an ideal gas (which air is a lot like) it gets hotter in proportion to it’s previous absolute temperature. Room temperature is already 273K, and the pressure down there is hundreds of time larger than at the surface. At some point the law would break down on the way, but you get the basic idea. It was probably as hot as the sun without any help from combustion
“Rushing” implies something like a wave. The thing crushed flat like the plastic tube it was, and would have done so too fast to even visually track.
If you were to slowly lower an open glass into the ocean, it would gradually fill with water. So i just think its the same with the sub, albeit faster?
Sure, but “faster” here means around the speed of sound, and that’s fundamentally a different thing from the playful streams we’re used to. The thing was waaay down there when it went.
If there was a tiny little hole somewhere that wasn’t getting larger, maybe it would slow down enough to just gradually fill the vessel. In that case, though, it would not have imploded. They found it in pieces and the US Navy heard the pop.
Yeah I guess if you think of the fact it actually went ‘boom’ you can imagine the water didnt really flow in but rather flew in very fast. There was probably a huge shockwave that killed them instantly
How did you get this number?
Physics and math. J/k. I’ve seen similar numbers thrown about. Here is a link to a Quora question What happens to the human body when a submarine implodes from 2 years ago that may be of interest.
