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.
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.
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.
When a submarine hull collapses, it moves inward at about 1,500 miles per hour - that’s 2,200 feet per second. A modern nuclear submarine’s hull radius is about 20 feet. So the time required for complete collapse is 20 / 2,200 seconds = about 1 millisecond.
A human brain responds instinctually to stimulus at about 25 milliseconds. Human rational response (sense→reason→act) is at best 150 milliseconds.
The air inside a sub has a fairly high concentration of hydrocarbon vapors. When the hull collapses it behaves like a very large piston on a very large Diesel engine. The air auto-ignites and an explosion follows the initial rapid implosion. Large blobs of fat (that would be humans) incinerate and are turned to ash and dust quicker than you can blink your eye.
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?
“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?
