> turning all organic matter to ash Is this actually true? I see it being repeated everywhere but there is a lot of mass in a human body. Can 100 milliseconds of "ignition" (as you put it) really burn off all of that?

I am no expert on any of this but was curious. So I entered some guesstimates in online calculators. Assuming they were at 12,500 ft / 3810m we get a pressure down there of 5546 PSI / 382 Bar. Compressing the air in the cabin from roughly atmospheric pressure to 382 Bar would heat it to above 1300°C, or 1600°F. As far as I understand, in milliseconds. That’s a lot of heat energy. The water around them will absorb som…

That doesn’t seem nearly hot enough to burn bodies before the water takes the place of all that hot air.

Do the bodies themselves get hot from being compressed? I’d assume largely no with our water content.

> OceanGate’s submersibles are the only known vessels to use real-time (RTM) hull health monitoring. With this RTM system, we can determine if the hull is compromised well before situations become life-threatening, and safely return to the surface. This innovative safety system is not currently covered by any classing agency. Given that Stockton Rush risked and lost his own life, he must have believed these words. He…

In an interview with James Cameron, he mentions[1] that he and other submersible industry experts believe that the system worked and that they did in fact have warning, as they had dropped the weights (which were found far away from the debris field) and were attempting to resurface before the implosion: [1]: "This Oceangate sub had sensors on the inside of the hull to give them a warning when it was starting to crac…

Reddit upvoting rich people dying from something extravagant? No, never.

That's too cynical. I'm sure if it was 5 unknown poor people or 5 random people the interest would have been the same. People just love following search and rescue stories, that's all there is to it. E.g. the Thailand Cave rescue, or the various mining-related rescues, the interest is always high.

No, it seems to me that Reddit broadly has a culture of hatred for specific groups they blame for most of the world's problems: boomers, and the extremely wealthy.

Tragic result, just as it were for the Titanic. The parallels between the hubris of what was said about each craft's capabilities, to the outcomes of blindly believing in it, down to even the irony in the names "Titanic" and "Titan" seems sadly poetic. Rest in peace.

The sinking of the Titanic and World War 1 are often mentioned in context, as marking the end of the long peace in Europe. I hope the sinking of the Titan won't mark something like World War 3 ...

I'm really curious about the carbon fibre design, I'm not a material expert but I do dive and for tanks they work because of the internal pressure of tank. The 'weaving' is supposed to be link connecting your two hands together interlocking fingers, in one direction you will meet a full resistance, but in the opposite direction your fingers will unlock. I have no idea but seems to me if there is external pressure the…

The looking glass was only rated for 4,000 feet. Implosion happened around 9,000 feet, which would suggest the glass handled over twice its rated depth.

Sorry but for metric units, 9k feet is around Looking glass rated 4k 'feet' around 1200 meters..

Not sure as there is a video of the ceo going to 3k meters solo in the titan on a 10~ hour trip..

That said, not much of this craft was 'rated' for anything..

More than that, one report mentioned the US Navy notified the search teams that they heard an explosion Sunday night and used it to limit the search area. The US Navy has literally has experience detecting underwater explosions (see project Azorian). It's not guaranteed of course, but any loud sound near the point of contact loss seems pretty open shut. Imo, it made a more interesting story in a slow news cycle. How…

There's a difference between knowing that a certain number of people are statistically dying right now vs knowing that 5 specific people are currently dying in a specific way.

Most of the people getting shot in mass shootings aren't doing something stupid on purpose.

Can someone walk me through what would have happened, physically, to a human body in the moment this happened. I’m curious. Similar to wondering what happens to people in space.

Randall Munroe probably said it best, "You would just stop being biology and start being physics."

I'm definitely going to hell for laughing at that.

and survived several dives before that to 13000ft, no?

I'm wondering this myself, they don't have any history logged of a trip before.

I think this might have been the first one. In minimal fairness, at least the owner put his money where is mouth was.

Sidebar : The owner/ceo did a 10 hour overall at max ~3kMeteres

A lot of measure of units thrown around in this thread too.

I'm surprised millionaires/billionaires didn't do better research on that company before going on the trip

Life is unpredictable. One day you are a billionaire who is eating lobsters, the other day the lobsters are eating you...

It's amazing how fast everyone goes from being covid/vaccine experts to {flavor of the week} experts to submersible experts.

There are experts on every topic, you shouldn't be surprised to hear from them when that is the topic of discussion.

Conveniently, my fairly average high school graduating class of around 350 has dozens of experts on nearly any popular topic.
